Interface PreparedStatement

All Superinterfaces:

All Known Subinterfaces:

CallableStatement

public interface PreparedStatement

extends Statement

An object that represents a precompiled SQL statement.

A SQL statement is precompiled and stored in aPreparedStatement 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 typeINTEGER, then the method setInt should be used.

If arbitrary parameter type conversions are required, the methodsetObject 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)

setAsciiStream

void setAsciiStream(int parameterIndex, InputStream x, int length) throws SQLException

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 parameter, it may be more practical to send it via ajava.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.

Parameters:

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:

parameterIndex - the first parameter is 1, the second is 2, ...

void setBinaryStream(int parameterIndex, InputStream x, int length) throws SQLException

Sets the designated parameter to the given input stream, which will have the specified number of bytes. When a very large binary value is input to a LONGVARBINARY parameter, it may be more practical to send it via ajava.io.InputStream object. The data will be read from the stream as needed until end-of-file is reached.

Note: This stream object can either be a standard Java stream object or your own subclass that implements the standard interface.

Parameters:

parameterIndex - the first parameter is 1, the second is 2, ...

x - the java input stream which contains the binary parameter value

length - the number of bytes in the stream

clearParameters

void clearParameters() throws SQLException

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.

Throws:

[SQLException](../../java/sql/SQLException.html "class in java.sql") - if a database access error occurs or this method is called on a closed PreparedStatement

setObject

void setObject(int parameterIndex, Object x, int targetSqlType) throws SQLException

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.

Parameters:

parameterIndex - the first parameter is 1, the second is 2, ...

x - the object containing the input parameter value

targetSqlType - the SQL type (as defined in java.sql.Types) to be sent to the database

Throws:

[SQLException](../../java/sql/SQLException.html "class in java.sql") - 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

[SQLFeatureNotSupportedException](../../java/sql/SQLFeatureNotSupportedException.html "class in java.sql") - if targetSqlType 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

Types

setObject

void setObject(int parameterIndex, Object x) throws SQLException

Sets the value of the designated parameter using the given object. The second parameter must be of type Object; therefore, thejava.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 implementingRef, 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 thesetObject(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 - the first parameter is 1, the second is 2, ...

x - the object containing the input parameter value

Throws:

[SQLException](../../java/sql/SQLException.html "class in java.sql") - 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

execute

boolean execute() throws SQLException

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 methodgetResultSet or getUpdateCount to retrieve the result; you must call getMoreResults to move to any subsequent result(s).

Returns:

true if the first result is a ResultSet object; false if the first result is an update count or there is no result

Throws:

[SQLException](../../java/sql/SQLException.html "class in java.sql") - if a database access error occurs; this method is called on a closed PreparedStatement or an argument is supplied to this method

See Also:

Statement.execute(java.lang.String), Statement.getResultSet(), Statement.getUpdateCount(), Statement.getMoreResults()

addBatch

void addBatch() throws SQLException

See Also:

Statement.addBatch(java.lang.String)

setCharacterStream

void setCharacterStream(int parameterIndex, Reader reader, int length) throws SQLException

Sets the designated parameter to the given Reader object, which is the given number of characters long. When a very large UNICODE value is input to a LONGVARCHAR parameter, it may be more practical to send it via ajava.io.Reader 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.

Note: This stream object can either be a standard Java stream object or your own subclass that implements the standard interface.

Parameters:

parameterIndex - the first parameter is 1, the second is 2, ...

reader - the java.io.Reader object that contains the Unicode data

length - the number of characters in the stream

Throws:

[SQLException](../../java/sql/SQLException.html "class in java.sql") - 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

Since:

1.2

setRef

void setRef(int parameterIndex, Ref x) throws SQLException

getMetaData

ResultSetMetaData getMetaData() throws SQLException

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 aPreparedStatement 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.

Returns:

the description of a ResultSet object's columns ornull if the driver cannot return aResultSetMetaData object

Throws:

[SQLException](../../java/sql/SQLException.html "class in java.sql") - if a database access error occurs or this method is called on a closed PreparedStatement

Since:

1.2

setDate

void setDate(int parameterIndex, Date x, Calendar cal) throws SQLException

Sets the designated parameter to the given java.sql.Date value, using the given Calendar object. The driver uses the Calendar object to construct an SQL DATE value, which the driver then sends to the database. With a Calendar object, the driver can calculate the date taking into account a custom timezone. If noCalendar object is specified, the driver uses the default timezone, which is that of the virtual machine running the application.

Parameters:

parameterIndex - the first parameter is 1, the second is 2, ...

x - the parameter value

cal - the Calendar object the driver will use to construct the date

Throws:

[SQLException](../../java/sql/SQLException.html "class in java.sql") - 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

Since:

1.2

setTime

void setTime(int parameterIndex, Time x, Calendar cal) throws SQLException

setNull

void setNull(int parameterIndex, int sqlType, String typeName) throws SQLException

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 - the first parameter is 1, the second is 2, ...

sqlType - a value from java.sql.Types

typeName - the fully-qualified name of an SQL user-defined type; ignored if the parameter is not a user-defined type or REF

The reader must contain the number of characters specified by length otherwise a SQLException will be generated when the PreparedStatement is executed. This method differs from the setCharacterStream (int, Reader, int) method because it informs the driver that the parameter value should be sent to the server as a CLOB. When the setCharacterStream method is used, the driver may have to do extra work to determine whether the parameter data should be sent to the server as a LONGVARCHAR or a CLOB

Parameters:

parameterIndex - index of the first parameter is 1, the second is 2, ...

reader - An object that contains the data to set the parameter value to.

length - the number of characters in the parameter data.

Throws:

[SQLException](../../java/sql/SQLException.html "class in java.sql") - 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 if the length specified is less than zero.

[SQLFeatureNotSupportedException](../../java/sql/SQLFeatureNotSupportedException.html "class in java.sql") - if the JDBC driver does not support this method

1.6

setBlob

void setBlob(int parameterIndex, InputStream inputStream, long length) throws SQLException

Sets the designated parameter to a InputStream object. The inputstream must contain the number of characters specified by length otherwise a SQLException will be generated when the PreparedStatement is executed. This method differs from the setBinaryStream (int, InputStream, int) method because it informs the driver that the parameter value should be sent to the server as a BLOB. When the setBinaryStream method is used, the driver may have to do extra work to determine whether the parameter data should be sent to the server as a LONGVARBINARY or a BLOB

Parameters:

parameterIndex - index of the first parameter is 1, the second is 2, ...

inputStream - An object that contains the data to set the parameter value to.

length - the number of bytes in the parameter data.

Throws:

[SQLException](../../java/sql/SQLException.html "class in java.sql") - 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; if the length specified is less than zero or if the number of bytes in the inputstream does not match the specfied length.

setNClob

void setNClob(int parameterIndex, Reader reader, long length) throws SQLException

Sets the designated parameter to a Reader object. The reader must contain the number of characters specified by length otherwise a SQLException will be generated when the PreparedStatement is executed. This method differs from the setCharacterStream (int, Reader, int) method because it informs the driver that the parameter value should be sent to the server as a NCLOB. When the setCharacterStream method is used, the driver may have to do extra work to determine whether the parameter data should be sent to the server as a LONGNVARCHAR or a NCLOB

Parameters:

parameterIndex - index of the first parameter is 1, the second is 2, ...

reader - An object that contains the data to set the parameter value to.

length - the number of characters in the parameter data.

Throws:

[SQLException](../../java/sql/SQLException.html "class in java.sql") - if parameterIndex does not correspond to a parameter marker in the SQL statement; if the length specified is less than zero; if the driver does not support national character sets; if the driver can detect that a data conversion error could occur; if a database access error occurs or this method is called on a closed PreparedStatement

setSQLXML

void setSQLXML(int parameterIndex, SQLXML xmlObject) throws SQLException

Sets the designated parameter to the given java.sql.SQLXML object. The driver converts this to an SQL XML value when it sends it to the database.

Parameters:

parameterIndex - index of the first parameter is 1, the second is 2, ...

xmlObject - a SQLXML object that maps an SQL XML value

Throws:

[SQLException](../../java/sql/SQLException.html "class in java.sql") - 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 java.xml.transform.Result,Writer or OutputStream has not been closed for the SQLXML object

[SQLFeatureNotSupportedException](../../java/sql/SQLFeatureNotSupportedException.html "class in java.sql") - if the JDBC driver does not support this method

Since:

1.6

setObject

void setObject(int parameterIndex, Object x, int targetSqlType, int scaleOrLength) throws SQLException

Sets the value of the designated parameter with the given object. The second argument must be an object type; for integral values, thejava.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 aReader then the reader must contain the number of characters specified by scaleOrLength. If these conditions are not true the driver will generate aSQLException 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 implementingRef, 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 - the first parameter is 1, the second is 2, ...

x - the object containing the input parameter value

targetSqlType - the SQL type (as defined in java.sql.Types) to be sent to the database. The scale argument may further qualify this type.

scaleOrLength - 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.

Throws:

[SQLException](../../java/sql/SQLException.html "class in java.sql") - 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 if the Java Object specified by x is an InputStream or Reader object and the value of the scale parameter is less than zero

[SQLFeatureNotSupportedException](../../java/sql/SQLFeatureNotSupportedException.html "class in java.sql") - if targetSqlType 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

setAsciiStream

void setAsciiStream(int parameterIndex, InputStream x, long length) throws SQLException

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 parameter, it may be more practical to send it via ajava.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.

Parameters:

parameterIndex - the first parameter is 1, the second is 2, ...

x - the Java input stream that contains the ASCII parameter value

length - the number of bytes in the stream

Throws:

[SQLException](../../java/sql/SQLException.html "class in java.sql") - 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
