mysqli_autocommit
(no version information, might be only in CVS)
mysqli->autocommit -- Turns on or off auto-commiting database modifications
Description
Procedural style:
bool
mysqli_autocommit ( mysqli link, bool mode )
Object oriented style (method)
class
mysqli {
bool
autocommit ( bool mode )
}
mysqli_autocommit() is used to turn on or off auto-commit mode
on queries for the database connection represented by the link
object.
Nota:
mysqli_autocommit() doesn't work with non transactional
table types (like MyISAM or ISAM).
To determine the current state of autocommit use the SQL command
'SELECT @@autocommit'.
Valori restituiti
Restituisce TRUE in caso di successo, FALSE in caso di fallimento.

/* turn autocommit on */ $mysqli->autocommit(TRUE);
if ($result = $mysqli->query("SELECT @@autocommit")) { $row = $result->fetch_row(); printf("Autocommit is %s\n", $row[0]); $result->free(); }
/* close connection */ $mysqli->close(); ?>

if ($result = mysqli_query($link, "SELECT @@autocommit")) { $row = mysqli_fetch_row($result); printf("Autocommit is %s\n", $row[0]); mysqli_free_result($result); }
