delt Posted May 6, 2007 Share Posted May 6, 2007 I have a database for storing the information of documents that users upload. I'm organizing the new entries by ID numbers (as traditionally done). When creating a new row, I'm having difficulty getting the last ID/highest ID so I can add 1 for the new ID of the new row. The code that I've been trying to fix (below) does well until I get to the 10th ID. After that, it recognizes "9" as the largest ID. $result = mysql_query("SELECT * FROM resources ORDER BY resource_id DESC"); $current = mysql_fetch_array($result); $id = $current[resource_id] + 1; How can this be resolved or what way would be better for performing this task? Thanks! (MySQL version 4.1.21) Quote Link to comment Share on other sites More sharing options...

Wildbug Posted May 7, 2007 Share Posted May 7, 2007 Are you using an AUTO_INCREMENT column? Quote Link to comment Share on other sites More sharing options...
