Bug description: error in mysqli when updating a record
Description:
------------
im getting an error when doing a second update on the same record in the
database.
mysqli_affected_rows() always returns 0 after the first update if you are
trying to update the same record.
ive used the mysql console to perform the same update and that works
fine.
Reproduce code:
---------------
$conn = mysqli_connect("localhost","root","****","****");
mysqli_autocommit($conn, FALSE);
$result = mysqli_query($conn,"update users set password = '$md5' where
username = '$myvar' ");
echo mysqli_affected_rows($conn)."<br />";
//check that no errors have occured or warnings
if (mysqli_warning_count($conn) == null )
{
echo mysqli_affected_rows($conn)."<br />";
if ( mysqli_affected_rows($conn) > 0)
{
echo "some data";
mysqli_commit ($conn);
}
}
else
{
echo "error";
mysqli_rollback($conn);
}
mysqli_free_result($result);
mysqli_close($conn);
}
Expected result:
----------------
it should return > 0 for mysqli_affected_rows and run the following code
Actual result:
--------------
returns 0 if updating the same record
