NAME

       DROP FUNCTION - remove a function

SYNOPSIS

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

DESCRIPTION

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

PARAMETERS

       IF EXISTS
	      Do not throw an error if the function does not exist. A notice is issued in this case.

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

       argmode
	      The mode of an argument: IN, OUT, INOUT, or VARIADIC.  If omitted, the default is IN.  Note that DROP FUNCTION does not actually pay
	      any attention to OUT arguments, since only the input arguments are needed to determine the function's identity.  So it is sufficient
	      to list the IN, INOUT, and VARIADIC arguments.

       argname
	      The name of an argument.	Note that DROP FUNCTION does not actually pay any attention to argument names,	since  only  the  argument
	      data types are needed to determine the function's identity.

       argtype
	      The data type(s) of the function's arguments (optionally schema-qualified), if any.

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

       RESTRICT
	      Refuse to drop the function if any objects depend on it. This is the default.

EXAMPLES

       This command removes the square root function:

       DROP FUNCTION sqrt(integer);

COMPATIBILITY

       A DROP FUNCTION statement is defined in the SQL standard, but it is not compatible with this command.

TABLE(7)							   SQL Commands 						     DROP TABLE(7)

NAME

       DROP TABLE - remove a table

SYNOPSIS

       DROP TABLE [ IF EXISTS ] name [, ...] [ CASCADE | RESTRICT ]

DESCRIPTION

       DROP  TABLE  removes tables from the database.  Only its owner can drop a table. To empty a table of rows without destroying the table, use
       DELETE [delete(7)] or TRUNCATE [truncate(7)].

       DROP TABLE always removes any indexes, rules, triggers, and constraints that exist for the target table.  However, to drop a table that	is
       referenced  by  a  view	or  a  foreign-key  constraint	of another table, CASCADE must be specified. (CASCADE will remove a dependent view
       entirely, but in the foreign-key case it will only remove the foreign-key constraint, not the other table entirely.)

PARAMETERS

       IF EXISTS
	      Do not throw an error if the table does not exist. A notice is issued in this case.

       name   The name (optionally schema-qualified) of the table to drop.

       CASCADE
	      Automatically drop objects that depend on the table (such as views).

       RESTRICT
	      Refuse to drop the table if any objects depend on it. This is the default.

EXAMPLES

       To destroy two tables, films and distributors:

       DROP TABLE films, distributors;

COMPATIBILITY

       This command conforms to the SQL standard, except that the standard only allows one table to be dropped per command, and apart from the	IF
       EXISTS option, which is a PostgreSQL extension.
