A little time on google told me that if you want to do a write after a read (or the other way around) you need to free up the query resource - apparently they hold read / write locks. so, free up $statement before doing a write: $sesdb = new PDO('sqlite:file.sqlite3'); $query="SELECT ZNAME, ZQUANTITY, ZPRODUCTID FROM ZITEM WHERE ZCategory != 14"; $statement= $sesdb->query($query); $result=$statement->fetchAll(); $statement=null; foreach ($result as $product) { $prodname=$product[0]; $prodqty = $product[1]; $prodid=$product[2]; $sql = "UPDATE ZITEM SET ZQUANTITY='0' WHERE ZPRODUCTID='{$prodid}'"; $sesdb->exec($sql); } On Wed, Aug 20, 2008 at 11:49 AM, Amy Gibbs <amy@willowtreecrafts.co.ukwrote:No errors reported, but it's not updating the db, error_reporting(E_ALL); $sesdb = new PDO('sqlite:file.sqlite3'); $query="SELECT ZNAME, ZQUANTITY, ZPRODUCTID FROM ZITEM WHERE ZCategory != 14"; $statement= $sesdb->query($query); $result=$statement->fetchAll(); foreach ($result as $product) { $prodname=$product[0]; $prodqty = $product[1]; $prodid=$product[2]; $sql = "UPDATE ZITEM SET ZQUANTITY='0' WHERE ZPRODUCTID={$prodid}"; $sesdb->exec($sql); } On 20 Aug 2008, at 10:11, Evert Lammerts wrote:can you put error_reporting(E_ALL); somewhere above the query and check if there's some output?
