DROP PROCEDURE v14

Name

DROP PROCEDURE — Remove a procedure.

Synopsis

DROP PROCEDURE [ IF EXISTS ] <name>
  [ ([ [ <argmode> ] [ <argname> ] <argtype> ] [, ...]) ]
  [ CASCADE | RESTRICT ]

Description

DROP PROCEDURE removes the definition of an existing procedure. To execute this command, you must be a superuser or the owner of the procedure. For an overloaded procedure, you must specify all input (IN, IN OUT) argument data types to the procedure.

The IF EXISTS, CASCADE, and RESTRICT parameters aren't compatible with Oracle databases. Only EDB Postgres Advanced Server uses them.

Parameters

IF EXISTS

Specifies not to throw an error if the procedure doesn't exist. A notice is issued instead.

name

The name (optionally schema-qualified) of an existing procedure.

argmode

The mode of an argument: IN, IN OUT, or OUT. The default is IN. DROP PROCEDURE ignores OUT arguments, since only the input arguments are needed to determine the procedure’s identity. List only the IN and IN OUT arguments.

!!! Note Specifying argmode isn't compatible with Oracle databases. It applies only to EDB Postgres Advanced Server.

argname

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

!!! Note Specifying argname isn't compatible with Oracle databases. It applies only to EDB Postgres Advanced Server.

argtype

The data type of an argument of the procedure.

!!! Note Specifying argtype isn't compatible with Oracle databases. It applies only to EDB Postgres Advanced Server.

CASCADE

Drop objects that depend on the procedure and all objects that depend on those objects.

RESTRICT

Prevent dropping the procedure if any objects depend on it. This is the default.

Examples

This example removes the select_emp procedure:

DROP PROCEDURE select_emp;
