CALL(7)			 PostgreSQL 13.1 Documentation		       CALL(7)

NAME
       CALL - invoke a procedure

SYNOPSIS
       CALL name ( [ argument ]	[, ...]	)

DESCRIPTION
       CALL executes a procedure.

       If the procedure	has any	output parameters, then	a result row will be
       returned, containing the	values of those	parameters.

PARAMETERS
       name
	   The name (optionally	schema-qualified) of the procedure.

       argument
	   An input argument for the procedure call. See Section 4.3 for the
	   full	details	on function and	procedure call syntax, including use
	   of named parameters.

NOTES
       The user	must have EXECUTE privilege on the procedure in	order to be
       allowed to invoke it.

       To call a function (not a procedure), use SELECT	instead.

       If CALL is executed in a	transaction block, then	the called procedure
       cannot execute transaction control statements. Transaction control
       statements are only allowed if CALL is executed in its own transaction.

       PL/pgSQL	handles	output parameters in CALL commands differently;	see
       Section 42.6.3.

EXAMPLES
	   CALL	do_db_maintenance();

COMPATIBILITY
       CALL conforms to	the SQL	standard.

SEE ALSO
       CREATE PROCEDURE	(CREATE_PROCEDURE(7))
