Required privilegesSyntaxParametersExamples

Amazon Redshift will no longer support the creation of new Python UDFs starting November 1, 2025. If you would like to use Python UDFs, create the UDFs prior to that date. Existing Python UDFs will continue to function as normal. For more information, see the blog post .

DROP PROCEDURE

Drops a procedure. To drop a procedure, both the procedure name and input argument data types (signature), are required. Optionally, you can include the full argument data types, including OUT arguments. To find the signature for a procedure, use the SHOW PROCEDURE command. For more information about procedure signatures, see PG_PROC_INFO.

Required privileges

Following are required privileges for DROP PROCEDURE:

  • Superuser

  • Users with the DROP PROCEDURE privilege

  • Procedure owner

Syntax

DROP PROCEDURE sp_name ( [ [ argname ] [ argmode ] argtype [, ...] ] )

Parameters

sp_name

The name of the procedure to be removed.

argname

The name of an input argument. DROP PROCEDURE ignores argument names, because only the argument data types are needed to determine the procedure's identity.

argmode

The mode of an argument, which can be IN, OUT, or INOUT. OUT arguments are optional because they aren't used to identify a stored procedure.

argtype

The data type of the input argument. For a list of the supported data types, see Data types.

Examples

The following example drops a stored procedure named quarterly_revenue.

DROP PROCEDURE quarterly_revenue(volume INOUT bigint, at_price IN numeric,result OUT int);
