I have been working on this version, still no luck tho. $query="select * from csv_stage2 order by parent_id"; $result=mysql_query($query); $num=mysql_numrows($result); $i=0; while ($i < $num) { $id=mysql_result($result,$i,"uid"); $query1="update csv_stage2 set prod_variant_id = $i where uid = $row[uid]"; mysql_query($query) or die(mysql_error()); ++$i; }

I need to update rows in a table with serial integer values for each GROUP For example 1, 2, 3, 4, 5, 6, ... and so on, for each grouping of rows BEFORE: GROUP, LINE_NUMBER 100 0 100 0 100 0 200 0 200 0 AFTER: GROUP,LINE_NUMBER 100 1 100 2 100 3 200 1 200 2 I have been working on the solution with no luck, please help if you can $result=mysql_query("select * from csv_stage2 order by parent_id"); $i = 1; while($row=mysql_fetch_array($result)){ if ($parent_id = $row[parent_id]) { mysql_query("update csv_stage2 set prod_variant_id = $i where uid = $row[uid]") or die (mysql_error()); } else { $parent_id = $row[parent_id]; $i = 1; mysql_query("update csv_stage2 set prod_variant_id = 1 where uid = $row[uid]") or die (mysql_error()); } ++$i; }
