DROP ROUTINE(7) PostgreSQL 12.4 Documentation DROP ROUTINE(7)

NAME

DROP_ROUTINE - remove a routine

SYNOPSIS

DROP ROUTINE [ IF EXISTS ] name [ ( [ [ argmode ] [ argname ] argtype [, ...] ] ) ] [, ...]


    [ CASCADE | RESTRICT ]

DESCRIPTION

DROP ROUTINE removes the definition of an existing routine, which can be an aggregate function, a normal function, or a procedure. See under DROP AGGREGATE (DROP_AGGREGATE(7)), DROP FUNCTION (DROP_FUNCTION(7)), and DROP PROCEDURE (DROP_PROCEDURE(7)) for the description of the parameters, more examples, and further details.

EXAMPLES

To drop the routine foo for type integer:

DROP ROUTINE foo(integer);

This command will work independent of whether foo is an aggregate, function, or procedure.

COMPATIBILITY

This command conforms to the SQL standard, with these PostgreSQL extensions:

•The standard only allows one routine to be dropped per command.

•The IF EXISTS option

•The ability to specify argument modes and names

•Aggregate functions are an extension.

SEE ALSO

DROP AGGREGATE (DROP_AGGREGATE(7)), DROP FUNCTION (DROP_FUNCTION(7)), DROP PROCEDURE (DROP_PROCEDURE(7)), ALTER ROUTINE (ALTER_ROUTINE(7))

Note that there is no CREATE ROUTINE command.
