Q&A > database programming > How do I lock tables using DBI and mySQL? contributed by filmo

Follow up question: Does the lock cover multiple statement handles? i.e.
$dbh->do("LOCK TABLES foo WRITE, bar READ"); $sth->prepare("SELECT x,y,z FROM bar"); $sth2->prepare("INSERT INTO foo SET a = ?"); while (@ary = $sth->fetchrow_array()) { $sth2->$execute($ary[0]); } $sth2->finish(); $sth->finish(); $dbh->do("UNLOCK TABLES");
Is this correct or will $sth2 not be able to access the tables because of the lock?
