DROP AGGREGATE

Function

DROP AGGREGATE deletes an aggregate function.

Precautions

DROP AGGREGATE deletes an existing aggregate function. Only the owner of the aggregate function can run this command.

Syntax

DROP AGGREGATE [ IF EXISTS ] name ( argtype [ , ... ] ) [ CASCADE | RESTRICT ]

Parameter Description

  • IF EXISTS

    Do not throw an error if the specified aggregation does not exist. A notice is issued in this case.

  • name

    Existing aggregate function name (optionally schema-qualified).

  • argtype

    Input data type of the aggregate function. To reference a zero-parameter aggregate function, use * to replace the input data type list.

  • CASCADE

    Cascade deletes objects that depend on the aggregate function.

  • RESTRICT

    Refuses to delete the aggregate function if any objects depend on it. This is a default processing.

Examples

Delete the aggregate function myavg of the integer type:

DROP AGGREGATE myavg(integer);

Compatibility

The SQL standard does not provide the DROP AGGREGATE statement.
