mysqli_autocommit (PHP 5) mysqli_autocommit (no version information, might be only in CVS) mysqli->autocommit -- Turns on or off auto-commiting database modifications DescriptionProcedural 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.
Note:
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'.
Return Values
Returns TRUE on success or FALSE on failure.
ExamplesExample 1. Object oriented style <?php
$mysqli = new mysqli("localhost", "my_user", "my_password", "world");
if (mysqli_connect_errno()) {
printf("Connect failed: %s\n", mysqli_connect_error());
exit();
}
/* 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();
?> |

Example 2. Procedural style <?php
$link = mysqli_connect("localhost", "my_user", "my_password", "world");
if (!$link) {
printf("Can't connect to localhost. Error: %s\n", mysqli_connect_error());
exit();
}
/* turn autocommit on */
mysqli_autocommit($link, TRUE);
if ($result = mysqli_query($link, "SELECT @@autocommit")) {
$row = mysqli_fetch_row($result);
printf("Autocommit is %s\n", $row[0]);
mysqli_free_result($result);
}
/* close connection */
mysqli_close($link);
?> |
