CALL

CALL — invoke a procedure

Synopsis

CALLname ( [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. SeeSection 4.3 for the full details on function and procedure call syntax, including use of named parameters.

Notes

The user must haveEXECUTE privilege on the procedure in order to be allowed to invoke it.

To call a function (not a procedure), useSELECT instead.

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

PL/pgSQL handles output parameters inCALL commands differently; seeSection 41.6.3.

Examples

CALL do_db_maintenance();

Compatibility

CALL conforms to the SQL standard.
