DROP PROCEDURE(7) | PostgreSQL 13.16 Documentation | DROP PROCEDURE(7) |
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 the user must be the owner of the procedure. The argument types to the procedure must be specified, since several different procedures can exist with the same name and different argument lists.
PARAMETERS¶
IF EXISTS
Do not throw an error if the procedure does not exist. A
notice is issued in this case.
name
The name (optionally schema-qualified) of an existing
procedure. If no argument list is specified, the name must be unique in its
schema.
argmode
The mode of an argument: IN or VARIADIC. If omitted, the
default is IN.
argname
The name of an argument. Note that DROP PROCEDURE
does not actually pay any attention to argument names, since only the argument
data types are needed to determine the procedure's identity.
argtype
The data type(s) of the procedure's arguments (optionally
schema-qualified), if any.
CASCADE
Automatically drop objects that depend on the procedure,
and in turn all objects that depend on those objects (see
Section 5.14).
RESTRICT
Refuse to drop the procedure if any objects depend on it.
This is the default.
EXAMPLES¶
DROP PROCEDURE do_db_maintenance();
COMPATIBILITY¶
This command conforms to the SQL standard, with these PostgreSQL extensions:
•The standard only allows one procedure to be
dropped per command.
•The IF EXISTS option
•The ability to specify argument modes and
names
