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 40.6.3.
Examples
CALL do_db_maintenance();
Compatibility
CALL
conforms to the SQL standard.
