Описаниеmixed db2_autocommit ( resource connection [, bool value] )

Список параметров
- connection
A valid database connection resource variable as returned from
db2_connect() or db2_pconnect().
- value
One of the following constants:
- DB2_AUTOCOMMIT_OFF
Turns AUTOCOMMIT off.
- DB2_AUTOCOMMIT_ON
Turns AUTOCOMMIT on.
Возвращаемые значения
When db2_autocommit() receives only the
connection parameter, it returns the current state
of AUTOCOMMIT for the requested connection as an integer value. A value of
0 indicates that AUTOCOMMIT is off, while a value of 1 indicates that
AUTOCOMMIT is on.
When db2_autocommit() receives both the
connection parameter and
autocommit parameter, it attempts to set the
AUTOCOMMIT state of the requested connection to the corresponding state.
Возвращает TRUE в случае успешного завершения или FALSE в случае возникновения ошибки.

if ($rc) {
print "Turning AUTOCOMMIT on succeeded.\n";
