RETURN (Snowflake Scripting) | Snowflake Documentation (original) (raw)

A table. Use TABLE(...) in the RETURN statement.

If your block is in a stored procedure, you must also specify the RETURNS TABLE... clause in theCREATE PROCEDURE statement.

Note

Currently, in the RETURNS TABLE(...) clause, you can’t specify GEOGRAPHY as a column type. This applies whether you are creating a stored or anonymous procedure.

CREATE OR REPLACE PROCEDURE test_return_geography_table_1() RETURNS TABLE(g GEOGRAPHY) ...

WITH test_return_geography_table_1() AS PROCEDURE RETURNS TABLE(g GEOGRAPHY) ... CALL test_return_geography_table_1();

If you attempt to specify GEOGRAPHY as a column type, calling the stored procedure results in the error:

Stored procedure execution error: data type of returned table does not match expected returned table type

To work around this issue, you can omit the column arguments and types in RETURNS TABLE().

CREATE OR REPLACE PROCEDURE test_return_geography_table_1() RETURNS TABLE() ...

WITH test_return_geography_table_1() AS PROCEDURE RETURNS TABLE() ... CALL test_return_geography_table_1();

If you want to return the data that a RESULTSET points to, pass the RESULTSET to TABLE(…), as shown in the example below:

CREATE PROCEDURE ... RETURNS TABLE(...) ... RETURN TABLE(my_result_set); ...
