(PECL ibm_db2 >= 1.0.0)
db2_autocommit — Returns or sets the AUTOCOMMIT state for a database connection
Sets or gets the AUTOCOMMIT behavior of the specified connection resource.
connectionA valid database connection resource variable as returned from db2_connect() or db2_pconnect().
valueOne of the following constants:
DB2_AUTOCOMMIT_OFFTurns AUTOCOMMIT off.
DB2_AUTOCOMMIT_ONTurns AUTOCOMMIT on.
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
DB2_AUTOCOMMIT_OFF indicates that AUTOCOMMIT is off,
while a value of DB2_AUTOCOMMIT_ON 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.
Retorna true em caso de sucesso ou false em caso de falha.
Exemplo #1 Retrieving the AUTOCOMMIT value for a connection
In the following example, a connection which has been created with AUTOCOMMIT turned off is tested with the db2_autocommit() function.
<?php
$options = array('autocommit' => DB2_AUTOCOMMIT_OFF);
$conn = db2_connect($database, $user, $password, $options);
$ac = db2_autocommit($conn);
if ($ac == DB2_AUTOCOMMIT_OFF) {
print "$ac -- AUTOCOMMIT is off.";
} else {
print "$ac -- AUTOCOMMIT is on.";
}
?>O exemplo acima produzirá:
0 -- AUTOCOMMIT is off.
Exemplo #2 Setting the AUTOCOMMIT value for a connection
In the following example, a connection which was initially created with AUTOCOMMIT turned off has its behavior changed to turn AUTOCOMMIT on.
<?php
$options = array('autocommit' => DB2_AUTOCOMMIT_OFF);
$conn = db2_connect($database, $user, $password, $options);
// Turn AUTOCOMMIT on
$rc = db2_autocommit($conn, DB2_AUTOCOMMIT_ON);
if ($rc) {
print "Turning AUTOCOMMIT on succeeded.\n";
}
// Check AUTOCOMMIT state
$ac = db2_autocommit($conn);
if ($ac == DB2_AUTOCOMMIT_OFF) {
print "$ac -- AUTOCOMMIT is off.";
} else {
print "$ac -- AUTOCOMMIT is on.";
}
?>O exemplo acima produzirá:
Turning AUTOCOMMIT on succeeded. 1 -- AUTOCOMMIT is on.
