NAME

       DROP FUNCTION - remove a user-defined function

SYNOPSIS

       DROP FUNCTION name ( [ type [, ...] ] ) [ CASCADE | RESTRICT ]

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

       type   The type of a parameter of the function.

       CASCADE
	      Automatically drop objects that depend on the function (such as operators or triggers).

       RESTRICT
	      Refuse to drop the function if there are any dependent objects.  This is the default.

   OUTPUTS
       DROP FUNCTION
	      Message returned if the command completes successfully.

       WARNING: RemoveFunction: Function "name" ("types") does not exist
	      This message is given if the function specified does not exist in the current database.

DESCRIPTION

       DROP  FUNCTION  will remove the definition of an existing function. To execute this command the user must be the owner of the function. The
       input argument types to the function must be specified, since several different functions may exist with the same name and different  argu-
       ment lists.

NOTES

       Refer to CREATE FUNCTION [create_function(7)] for information on creating functions.

EXAMPLES

       This command removes the square root function:

       DROP FUNCTION sqrt(integer);

COMPATIBILITY

       A DROP FUNCTION statement is defined in SQL99. One of its syntax forms is similar to PostgreSQL's.

SYNOPSIS

       DROP [ PROCEDURAL ] LANGUAGE name [ CASCADE | RESTRICT ]

   INPUTS
       name   The name of an existing procedural language. For backward compatibility, the name may be enclosed by single quotes.

       CASCADE
	      Automatically drop objects that depend on the language (such as functions in the language).

       RESTRICT
	      Refuse to drop the language if there are any dependent objects.  This is the default.

   OUTPUTS
       DROP LANGUAGE
	      This message is returned if the language is successfully dropped.

       ERROR: Language "name" doesn't exist
	      This message occurs if a language called name is not found in the database.

DESCRIPTION

       DROP PROCEDURAL LANGUAGE will remove the definition of the previously registered procedural language called name.

   NOTES
       The DROP PROCEDURAL LANGUAGE statement is a PostgreSQL language extension.

       Refer to CREATE LANGUAGE [create_language(7)] for information on how to create procedural languages.

USAGE

       This command removes the PL/Sample language:

       DROP LANGUAGE plsample;
