PreparedStatement | API reference | Android Developers (original) (raw)
interface PreparedStatement : Statement
An object that represents a precompiled SQL statement.
A SQL statement is precompiled and stored in a PreparedStatement
object. This object can then be used to efficiently execute this statement multiple times.
Note: The setter methods (setShort
, setString
, and so on) for setting IN parameter values must specify types that are compatible with the defined SQL type of the input parameter. For instance, if the IN parameter has SQL type INTEGER
, then the method setInt
should be used.
If arbitrary parameter type conversions are required, the method setObject
should be used with a target SQL type.
In the following example of setting a parameter, con
represents an active connection:
PreparedStatement pstmt = con.prepareStatement("UPDATE EMPLOYEES SET SALARY = ? WHERE ID = ?"); pstmt.setBigDecimal(1, 153833.00) pstmt.setInt(2, 110592)

From class Statement Unit addBatch(sql: String!) Adds the given SQL command to the current list of commmands for this Statement object. The commands in this list can be executed as a batch by calling the method executeBatch. **Note:**This method cannot be called on a PreparedStatement or CallableStatement. Unit cancel() Cancels this Statement object if both the DBMS and driver support aborting an SQL statement. This method can be used by one thread to cancel a statement that is being executed by another thread. Unit clearBatch() Empties this Statement object's current list of SQL commands. Unit clearWarnings() Clears all the warnings reported on this Statement object. After a call to this method, the method getWarnings will return null until a new warning is reported for this Statement object. Unit close() Releases this Statement object's database and JDBC resources immediately instead of waiting for this to happen when it is automatically closed. It is generally good practice to release resources as soon as you are finished with them to avoid tying up database resources. Calling the method close on a Statement object that is already closed has no effect. **Note:**When a Statement object is closed, its current ResultSet object, if one exists, is also closed. Boolean execute(sql: String!) Executes the given SQL statement, which may return multiple results. In some (uncommon) situations, a single SQL statement may return multiple result sets and/or update counts. Normally you can ignore this unless you are (1) executing a stored procedure that you know may return multiple results or (2) you are dynamically executing an unknown SQL string. The execute method executes an SQL statement and indicates the form of the first result. You must then use the methods getResultSet or getUpdateCount to retrieve the result, and getMoreResults to move to any subsequent result(s). **Note:**This method cannot be called on a PreparedStatement or CallableStatement. Boolean execute(sql: String!, autoGeneratedKeys: Int) Executes the given SQL statement, which may return multiple results, and signals the driver that any auto-generated keys should be made available for retrieval. The driver will ignore this signal if the SQL statement is not an INSERT statement, or an SQL statement able to return auto-generated keys (the list of such statements is vendor-specific). In some (uncommon) situations, a single SQL statement may return multiple result sets and/or update counts. Normally you can ignore this unless you are (1) executing a stored procedure that you know may return multiple results or (2) you are dynamically executing an unknown SQL string. The execute method executes an SQL statement and indicates the form of the first result. You must then use the methods getResultSet or getUpdateCount to retrieve the result, and getMoreResults to move to any subsequent result(s). **Note:**This method cannot be called on a PreparedStatement or CallableStatement. Boolean execute(sql: String!, columnIndexes: IntArray!) Executes the given SQL statement, which may return multiple results, and signals the driver that the auto-generated keys indicated in the given array should be made available for retrieval. This array contains the indexes of the columns in the target table that contain the auto-generated keys that should be made available. The driver will ignore the array if the SQL statement is not an INSERT statement, or an SQL statement able to return auto-generated keys (the list of such statements is vendor-specific). Under some (uncommon) situations, a single SQL statement may return multiple result sets and/or update counts. Normally you can ignore this unless you are (1) executing a stored procedure that you know may return multiple results or (2) you are dynamically executing an unknown SQL string. The execute method executes an SQL statement and indicates the form of the first result. You must then use the methods getResultSet or getUpdateCount to retrieve the result, and getMoreResults to move to any subsequent result(s). **Note:**This method cannot be called on a PreparedStatement or CallableStatement. Boolean execute(sql: String!, columnNames: Array<String!>!) Executes the given SQL statement, which may return multiple results, and signals the driver that the auto-generated keys indicated in the given array should be made available for retrieval. This array contains the names of the columns in the target table that contain the auto-generated keys that should be made available. The driver will ignore the array if the SQL statement is not an INSERT statement, or an SQL statement able to return auto-generated keys (the list of such statements is vendor-specific). In some (uncommon) situations, a single SQL statement may return multiple result sets and/or update counts. Normally you can ignore this unless you are (1) executing a stored procedure that you know may return multiple results or (2) you are dynamically executing an unknown SQL string. The execute method executes an SQL statement and indicates the form of the first result. You must then use the methods getResultSet or getUpdateCount to retrieve the result, and getMoreResults to move to any subsequent result(s). **Note:**This method cannot be called on a PreparedStatement or CallableStatement. IntArray! executeBatch() Submits a batch of commands to the database for execution and if all commands execute successfully, returns an array of update counts. The int elements of the array that is returned are ordered to correspond to the commands in the batch, which are ordered according to the order in which they were added to the batch. The elements in the array returned by the method executeBatch may be one of the following: A number greater than or equal to zero -- indicates that the command was processed successfully and is an update count giving the number of rows in the database that were affected by the command's execution A value of SUCCESS_NO_INFO -- indicates that the command was processed successfully but that the number of rows affected is unknown If one of the commands in a batch update fails to execute properly, this method throws a BatchUpdateException, and a JDBC driver may or may not continue to process the remaining commands in the batch. However, the driver's behavior must be consistent with a particular DBMS, either always continuing to process commands or never continuing to process commands. If the driver continues processing after a failure, the array returned by the method BatchUpdateException.getUpdateCounts will contain as many elements as there are commands in the batch, and at least one of the elements will be the following: A value of EXECUTE_FAILED -- indicates that the command failed to execute successfully and occurs only if a driver continues to process commands after a command fails The possible implementations and return values have been modified in the Java 2 SDK, Standard Edition, version 1.3 to accommodate the option of continuing to proccess commands in a batch update after a BatchUpdateException obejct has been thrown. ResultSet! executeQuery(sql: String!) Executes the given SQL statement, which returns a single ResultSet object. **Note:**This method cannot be called on a PreparedStatement or CallableStatement. Int executeUpdate(sql: String!) Executes the given SQL statement, which may be an INSERT, UPDATE, or DELETE statement or an SQL statement that returns nothing, such as an SQL DDL statement. **Note:**This method cannot be called on a PreparedStatement or CallableStatement. Int executeUpdate(sql: String!, autoGeneratedKeys: Int) Executes the given SQL statement and signals the driver with the given flag about whether the auto-generated keys produced by this Statement object should be made available for retrieval. The driver will ignore the flag if the SQL statement is not an INSERT statement, or an SQL statement able to return auto-generated keys (the list of such statements is vendor-specific). **Note:**This method cannot be called on a PreparedStatement or CallableStatement. Int executeUpdate(sql: String!, columnIndexes: IntArray!) Executes the given SQL statement and signals the driver that the auto-generated keys indicated in the given array should be made available for retrieval. This array contains the indexes of the columns in the target table that contain the auto-generated keys that should be made available. The driver will ignore the array if the SQL statement is not an INSERT statement, or an SQL statement able to return auto-generated keys (the list of such statements is vendor-specific). **Note:**This method cannot be called on a PreparedStatement or CallableStatement. Int executeUpdate(sql: String!, columnNames: Array<String!>!) Executes the given SQL statement and signals the driver that the auto-generated keys indicated in the given array should be made available for retrieval. This array contains the names of the columns in the target table that contain the auto-generated keys that should be made available. The driver will ignore the array if the SQL statement is not an INSERT statement, or an SQL statement able to return auto-generated keys (the list of such statements is vendor-specific). **Note:**This method cannot be called on a PreparedStatement or CallableStatement. Connection! getConnection() Retrieves the Connection object that produced this Statement object. Int getFetchDirection() Retrieves the direction for fetching rows from database tables that is the default for result sets generated from this Statement object. If this Statement object has not set a fetch direction by calling the method setFetchDirection, the return value is implementation-specific. Int getFetchSize() Retrieves the number of result set rows that is the default fetch size for ResultSet objects generated from this Statement object. If this Statement object has not set a fetch size by calling the method setFetchSize, the return value is implementation-specific. ResultSet! getGeneratedKeys() Retrieves any auto-generated keys created as a result of executing this Statement object. If this Statement object did not generate any keys, an empty ResultSet object is returned. **Note:**If the columns which represent the auto-generated keys were not specified, the JDBC driver implementation will determine the columns which best represent the auto-generated keys. Int getMaxFieldSize() Retrieves the maximum number of bytes that can be returned for character and binary column values in a ResultSet object produced by this Statement object. This limit applies only to BINARY, VARBINARY, LONGVARBINARY, CHAR, VARCHAR, NCHAR, NVARCHAR, LONGNVARCHAR and LONGVARCHAR columns. If the limit is exceeded, the excess data is silently discarded. Int getMaxRows() Retrieves the maximum number of rows that a ResultSet object produced by this Statement object can contain. If this limit is exceeded, the excess rows are silently dropped. Boolean getMoreResults() Moves to this Statement object's next result, returns true if it is a ResultSet object, and implicitly closes any current ResultSet object(s) obtained with the method getResultSet. There are no more results when the following is true: // stmt is a Statement object ((stmt.getMoreResults() == false) && (stmt.getUpdateCount() == -1)) Boolean getMoreResults(current: Int) Moves to this Statement object's next result, deals with any current ResultSet object(s) according to the instructions specified by the given flag, and returns true if the next result is a ResultSet object. There are no more results when the following is true: // stmt is a Statement object ((stmt.getMoreResults(current) == false) && (stmt.getUpdateCount() == -1)) Int getQueryTimeout() Retrieves the number of seconds the driver will wait for a Statement object to execute. If the limit is exceeded, a SQLException is thrown. ResultSet! getResultSet() Retrieves the current result as a ResultSet object. This method should be called only once per result. Int getResultSetConcurrency() Retrieves the result set concurrency for ResultSet objects generated by this Statement object. Int getResultSetHoldability() Retrieves the result set holdability for ResultSet objects generated by this Statement object. Int getResultSetType() Retrieves the result set type for ResultSet objects generated by this Statement object. Int getUpdateCount() Retrieves the current result as an update count; if the result is a ResultSet object or there are no more results, -1 is returned. This method should be called only once per result. SQLWarning! getWarnings() Retrieves the first warning reported by calls on this Statement object. Subsequent Statement object warnings will be chained to this SQLWarning object. The warning chain is automatically cleared each time a statement is (re)executed. This method may not be called on a closed Statement object; doing so will cause an SQLException to be thrown. Note: If you are processing a ResultSet object, any warnings associated with reads on that ResultSet object will be chained on it rather than on the Statement object that produced it. Boolean isClosed() Retrieves whether this Statement object has been closed. A Statement is closed if the method close has been called on it, or if it is automatically closed. Boolean isPoolable() Returns a value indicating whether the Statement is poolable or not. Unit setCursorName(name: String!) Sets the SQL cursor name to the given String, which will be used by subsequent Statement object execute methods. This name can then be used in SQL positioned update or delete statements to identify the current row in the ResultSet object generated by this statement. If the database does not support positioned update/delete, this method is a noop. To insure that a cursor has the proper isolation level to support updates, the cursor's SELECT statement should have the form SELECT FOR UPDATE. If FOR UPDATE is not present, positioned updates may fail. Note: By definition, the execution of positioned updates and deletes must be done by a different Statement object than the one that generated the ResultSet object being used for positioning. Also, cursor names must be unique within a connection. Unit setEscapeProcessing(enable: Boolean) Sets escape processing on or off. If escape scanning is on (the default), the driver will do escape substitution before sending the SQL statement to the database. Note: Since prepared statements have usually been parsed prior to making this call, disabling escape processing for PreparedStatements objects will have no effect. Unit setFetchDirection(direction: Int) Gives the driver a hint as to the direction in which rows will be processed in ResultSet objects created using this Statement object. The default value is ResultSet.FETCH_FORWARD. Note that this method sets the default fetch direction for result sets generated by this Statement object. Each result set has its own methods for getting and setting its own fetch direction. Unit setFetchSize(rows: Int) Gives the JDBC driver a hint as to the number of rows that should be fetched from the database when more rows are needed for ResultSet objects genrated by this Statement. If the value specified is zero, then the hint is ignored. The default value is zero. Unit setMaxFieldSize(max: Int) Sets the limit for the maximum number of bytes that can be returned for character and binary column values in a ResultSet object produced by this Statement object. This limit applies only to BINARY, VARBINARY, LONGVARBINARY, CHAR, VARCHAR, NCHAR, NVARCHAR, LONGNVARCHAR and LONGVARCHAR fields. If the limit is exceeded, the excess data is silently discarded. For maximum portability, use values greater than 256. Unit setMaxRows(max: Int) Sets the limit for the maximum number of rows that any ResultSet object generated by this Statement object can contain to the given number. If the limit is exceeded, the excess rows are silently dropped. Unit setPoolable(poolable: Boolean) Requests that a Statement be pooled or not pooled. The value specified is a hint to the statement pool implementation indicating whether the applicaiton wants the statement to be pooled. It is up to the statement pool manager as to whether the hint is used. The poolable value of a statement is applicable to both internal statement caches implemented by the driver and external statement caches implemented by application servers and other applications. By default, a Statement is not poolable when created, and a PreparedStatement and CallableStatement are poolable when created. Unit setQueryTimeout(seconds: Int) Sets the number of seconds the driver will wait for a Statement object to execute to the given number of seconds. By default there is no limit on the amount of time allowed for a running statement to complete. If the limit is exceeded, an SQLTimeoutException is thrown. A JDBC driver must apply this limit to the execute, executeQuery and executeUpdate methods. Note: JDBC driver implementations may also apply this limit to ResultSet methods (consult your driver vendor documentation for details). Note: In the case of Statement batching, it is implementation defined as to whether the time-out is applied to individual SQL commands added via the addBatch method or to the entire batch of SQL commands invoked by the executeBatch method (consult your driver vendor documentation for details). |
From class Wrapper Boolean isWrapperFor(iface: Class<*>!) Returns true if this either implements the interface argument or is directly or indirectly a wrapper for an object that does. Returns false otherwise. If this implements the interface then return true, else if this is a wrapper then return the result of recursively calling isWrapperFor on the wrapped object. If this does not implement the interface and is not a wrapper, return false. This method should be implemented as a low-cost operation compared to unwrap so that callers can use this method to avoid expensive unwrap calls that may fail. If this method returns true then calling unwrap with the same argument should succeed. T unwrap(iface: Class<T>!) Returns an object that implements the given interface to allow access to non-standard methods, or standard methods not exposed by the proxy. If the receiver implements the interface then the result is the receiver or a proxy for the receiver. If the receiver is a wrapper and the wrapped object implements the interface then the result is the wrapped object or a proxy for the wrapped object. Otherwise return the the result of calling unwrap recursively on the wrapped object or a proxy for that result. If the receiver is not a wrapper and does not implement the interface, then an SQLException is thrown. |
Public methods
addBatch
abstract fun addBatch(): Unit
Adds a set of parameters to this PreparedStatement
object's batch of commands.
Exceptions | |
---|---|
java.sql.SQLException | if a database access error occurs or this method is called on a closed PreparedStatement |
clearParameters
abstract fun clearParameters(): Unit
Clears the current parameter values immediately.
In general, parameter values remain in force for repeated use of a statement. Setting a parameter value automatically clears its previous value. However, in some cases it is useful to immediately release the resources used by the current parameter values; this can be done by calling the method clearParameters
.
Exceptions | |
---|---|
java.sql.SQLException | if a database access error occurs or this method is called on a closed PreparedStatement |
execute
abstract fun execute(): Boolean
Executes the SQL statement in this PreparedStatement
object, which may be any kind of SQL statement. Some prepared statements return multiple results; the execute
method handles these complex statements as well as the simpler form of statements handled by the methods executeQuery
and executeUpdate
.
The execute
method returns a boolean
to indicate the form of the first result. You must call either the method getResultSet
or getUpdateCount
to retrieve the result; you must call getMoreResults
to move to any subsequent result(s).
Return | |
---|---|
Boolean | true if the first result is a ResultSet object; false if the first result is an update count or there is no result |
Exceptions | |
---|---|
java.sql.SQLTimeoutException | when the driver has determined that the timeout value that was specified by the setQueryTimeout method has been exceeded and has at least attempted to cancel the currently running Statement |
java.sql.SQLException | if a database access error occurs; this method is called on a closed PreparedStatement or an argument is supplied to this method |
executeQuery
abstract fun executeQuery(): ResultSet!
Executes the SQL query in this PreparedStatement
object and returns the ResultSet
object generated by the query.
Return | |
---|---|
ResultSet! | a ResultSet object that contains the data produced by the query; never null |
Exceptions | |
---|---|
java.sql.SQLTimeoutException | when the driver has determined that the timeout value that was specified by the setQueryTimeout method has been exceeded and has at least attempted to cancel the currently running Statement |
java.sql.SQLException | if a database access error occurs; this method is called on a closed PreparedStatement or the SQL statement does not return a ResultSet object |
executeUpdate
abstract fun executeUpdate(): Int
Executes the SQL statement in this PreparedStatement
object, which must be an SQL Data Manipulation Language (DML) statement, such as INSERT
, UPDATE
or DELETE
; or an SQL statement that returns nothing, such as a DDL statement.
Return | |
---|---|
Int | either (1) the row count for SQL Data Manipulation Language (DML) statements or (2) 0 for SQL statements that return nothing |
Exceptions | |
---|---|
java.sql.SQLTimeoutException | when the driver has determined that the timeout value that was specified by the setQueryTimeout method has been exceeded and has at least attempted to cancel the currently running Statement |
java.sql.SQLException | if a database access error occurs; this method is called on a closed PreparedStatement or the SQL statement returns a ResultSet object |
getMetaData
abstract fun getMetaData(): ResultSetMetaData!
Retrieves a ResultSetMetaData
object that contains information about the columns of the ResultSet
object that will be returned when this PreparedStatement
object is executed.
Because a PreparedStatement
object is precompiled, it is possible to know about the ResultSet
object that it will return without having to execute it. Consequently, it is possible to invoke the method getMetaData
on a PreparedStatement
object rather than waiting to execute it and then invoking the ResultSet.getMetaData
method on the ResultSet
object that is returned.
NOTE: Using this method may be expensive for some drivers due to the lack of underlying DBMS support.
Return | |
---|---|
ResultSetMetaData! | the description of a ResultSet object's columns or null if the driver cannot return a ResultSetMetaData object |
Exceptions | |
---|---|
java.sql.SQLException | if a database access error occurs or this method is called on a closed PreparedStatement |
java.sql.SQLFeatureNotSupportedException | if the JDBC driver does not support this method |
getParameterMetaData
abstract fun getParameterMetaData(): ParameterMetaData!
Retrieves the number, types and properties of this PreparedStatement
object's parameters.
Return | |
---|---|
ParameterMetaData! | a ParameterMetaData object that contains information about the number, types and properties for each parameter marker of this PreparedStatement object |
Exceptions | |
---|---|
java.sql.SQLException | if a database access error occurs or this method is called on a closed PreparedStatement |
setArray
abstract fun setArray(
parameterIndex: Int,
x: Array!
): Unit
Sets the designated parameter to the given java.sql.Array
object. The driver converts this to an SQL ARRAY
value when it sends it to the database.
Parameters | |
---|---|
parameterIndex | Int: the first parameter is 1, the second is 2, ... |
x | Array!: an Array object that maps an SQL ARRAY value |
Exceptions | |
---|---|

java.sql.SQLException | if parameterIndex does not correspond to a parameter marker in the SQL statement; if a database access error occurs or this method is called on a closed PreparedStatement |
setAsciiStream
abstract fun setAsciiStream(
parameterIndex: Int,
x: InputStream!
): Unit
Sets the designated parameter to the given input stream. When a very large ASCII value is input to a LONGVARCHAR
parameter, it may be more practical to send it via a java.io.InputStream
. Data will be read from the stream as needed until end-of-file is reached. The JDBC driver will do any necessary conversion from ASCII to the database char format.
Note: This stream object can either be a standard Java stream object or your own subclass that implements the standard interface.
Note: Consult your JDBC driver documentation to determine if it might be more efficient to use a version of setAsciiStream
which takes a length parameter.
Parameters | |
---|---|
parameterIndex | Int: the first parameter is 1, the second is 2, ... |
x | InputStream!: the Java input stream that contains the ASCII parameter value |
Exceptions | |
---|---|
java.sql.SQLFeatureNotSupportedException | if the JDBC driver does not support this method |
java.sql.SQLException | if parameterIndex does not correspond to a parameter marker in the SQL statement; if a database access error occurs or this method is called on a closed PreparedStatement |
setAsciiStream
abstract fun setAsciiStream(
parameterIndex: Int,
x: InputStream!,
length: Int
): Unit
Sets the designated parameter to the given input stream, which will have the specified number of bytes. When a very large ASCII value is input to a LONGVARCHAR

setNull
abstract fun setNull(
parameterIndex: Int,
sqlType: Int,
typeName: String!
): Unit
Sets the designated parameter to SQL NULL
. This version of the method setNull
should be used for user-defined types and REF type parameters. Examples of user-defined types include: STRUCT, DISTINCT, JAVA_OBJECT, and named array types.
Note: To be portable, applications must give the SQL type code and the fully-qualified SQL type name when specifying a NULL user-defined or REF parameter. In the case of a user-defined type the name is the type name of the parameter itself. For a REF parameter, the name is the type name of the referenced type. If a JDBC driver does not need the type code or type name information, it may ignore it. Although it is intended for user-defined and Ref parameters, this method may be used to set a null parameter of any JDBC type. If the parameter does not have a user-defined or REF type, the given typeName is ignored.
Parameters | |
---|---|
parameterIndex | Int: the first parameter is 1, the second is 2, ... |
sqlType | Int: a value from java.sql.Types |
typeName | String!: the fully-qualified name of an SQL user-defined type; ignored if the parameter is not a user-defined type or REF |

java.sql.SQLFeatureNotSupportedException | if sqlType is a ARRAY, BLOB, CLOB, DATALINK, JAVA_OBJECT, NCHAR, NCLOB, NVARCHAR, LONGNVARCHAR, REF, ROWID, SQLXML or STRUCT data type and the JDBC driver does not support this data type or if the JDBC driver does not support this method |
setObject
abstract fun setObject(
parameterIndex: Int,
x: Any!
): Unit
Sets the value of the designated parameter using the given object. The second parameter must be of type Object
; therefore, the java.lang
equivalent objects should be used for built-in types.
The JDBC specification specifies a standard mapping from Java Object
types to SQL types. The given argument will be converted to the corresponding SQL type before being sent to the database.
Note that this method may be used to pass datatabase- specific abstract data types, by using a driver-specific Java type. If the object is of a class implementing the interface SQLData
, the JDBC driver should call the method SQLData.writeSQL
to write it to the SQL data stream. If, on the other hand, the object is of a class implementing Ref
, Blob
, Clob
, NClob
, Struct
, java.net.URL
, RowId
, SQLXML
or Array
, the driver should pass it to the database as a value of the corresponding SQL type.
Note: Not all databases allow for a non-typed Null to be sent to the backend. For maximum portability, the setNull
or the setObject(int parameterIndex, Object x, int sqlType)
method should be used instead of setObject(int parameterIndex, Object x)
.
Note: This method throws an exception if there is an ambiguity, for example, if the object is of a class implementing more than one of the interfaces named above.
Parameters | |
---|---|
parameterIndex | Int: the first parameter is 1, the second is 2, ... |
x | Any!: the object containing the input parameter value |
Exceptions | |
---|---|
java.sql.SQLException | if parameterIndex does not correspond to a parameter marker in the SQL statement; if a database access error occurs; this method is called on a closed PreparedStatement or the type of the given object is ambiguous |
setObject
abstract fun setObject(
parameterIndex: Int,
x: Any!,
targetSqlType: Int
): Unit
Sets the value of the designated parameter with the given object. This method is like the method setObject
above, except that it assumes a scale of zero.

): Unit
Sets the value of the designated parameter with the given object. The second argument must be an object type; for integral values, the java.lang
equivalent objects should be used. If the second argument is an InputStream
then the stream must contain the number of bytes specified by scaleOrLength. If the second argument is a Reader
then the reader must contain the number of characters specified by scaleOrLength. If these conditions are not true the driver will generate a SQLException
when the prepared statement is executed.
The given Java object will be converted to the given targetSqlType before being sent to the database. If the object has a custom mapping (is of a class implementing the interface SQLData
), the JDBC driver should call the method SQLData.writeSQL
to write it to the SQL data stream. If, on the other hand, the object is of a class implementing Ref
, Blob
, Clob
, NClob
, Struct
, java.net.URL
, or Array
, the driver should pass it to the database as a value of the corresponding SQL type.
Note that this method may be used to pass database-specific abstract data types.
Parameters | |
---|---|
parameterIndex | Int: the first parameter is 1, the second is 2, ... |
x | Any!: the object containing the input parameter value |
targetSqlType | Int: the SQL type (as defined in java.sql.Types) to be sent to the database. The scale argument may further qualify this type. |
scaleOrLength | Int: for java.sql.Types.DECIMAL or java.sql.Types.NUMERIC types, this is the number of digits after the decimal point. For Java Object types InputStream and Reader, this is the length of the data in the stream or reader. For all other types, this value will be ignored. |

Deprecated: Use setCharacterStream
Sets the designated parameter to the given input stream, which will have the specified number of bytes. When a very large Unicode value is input to a LONGVARCHAR
parameter, it may be more practical to send it via a java.io.InputStream
object. The data will be read from the stream as needed until end-of-file is reached. The JDBC driver will do any necessary conversion from Unicode to the database char format. The byte format of the Unicode stream must be a Java UTF-8, as defined in the Java Virtual Machine Specification.
Note: This stream object can either be a standard Java stream object or your own subclass that implements the standard interface.
Parameters | |
