Does this list of inspections exist in the db? Could you not use an
INSERT INTO SELECT * FROM TABLE WHERE type statement...much less
processing overhead then

Cat, the other other white meat
Hi Bastien,
Something like this is what you mean?
if (!empty($Go)) { $query = "SELECT * FROM restaurants WHERE name = '$ucName' AND address = '$ucAddress' AND inDate ='$inDate' AND inType = '$inType' "; $result = mysql_query ($query); $row = mysql_fetch_object ($result); If (mysql_num_rows($result) == 0) { $sql = "INSERT INTO `restaurants` (name, address, inDate, inType, notes, critical, cviolations, noncritical) VALUES ("; $sql .= " '$ucName', '$ucAddress', '$inDate', '$inType', '$notes', '$critical', '$cleanViolations', '$noncritical')"; $result = mysql_query($sql) or die(mysql_error()); } So if all three things are met, that entry is in there if not insert right?
