Help for commit of rollback in mysql

[Karthik.gautham]

Hi guys I want to commit the transaction if all the queries executed in the loop, or else I need to rollback how do i do this, I tried this , but I am not sure how efficient it is.

       mysql_query("START TRANSACTION");

for($i=0;$i<100;$i++)
{
    $res=mysql_query("some query")
    array_push($array,$res);
}


if(in_array(0,$array))
          mysql_query("rollback");
           else
          mysql_query("commit");

If its there any efficient method plese let me know, any help will be much appriciated,
Thanks in advance.

While I'm sure this can be done with the very old mysql extension, mysqli makes this very easy. This is taken from the php mysqli::commit documentation. http://www.php.net/manual/en/mysqli.commit.php

<?php
$mysqli = new mysqli("localhost", "my_user", "my_password", "world");

/* check connection */
if (mysqli_connect_errno()) {
    printf("Connect failed: %s\n", mysqli_connect_error());
    exit();
}

$mysqli->query("CREATE TABLE Language LIKE CountryLanguage");

/* set autocommit to off */
$mysqli->autocommit(FALSE);

/* Insert some values */
$mysqli->query("INSERT INTO Language VALUES ('DEU', 'Bavarian', 'F', 11.2)");
$mysqli->query("INSERT INTO Language VALUES ('DEU', 'Swabian', 'F', 9.4)");

/* commit transaction */
$mysqli->commit();

/* drop table */
$mysqli->query("DROP TABLE Language");

/* close connection */
$mysqli->close();
?>
