CALL(7)                           PostgreSQL 12.3 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.
