CALL
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. 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 43.6.3
.
Examples
CALL do_db_maintenance();
Compatibility
CALL
conforms to the SQL standard.
