  hi,
  
  I use Example module to write a custom module but the $dbconn->GenId(...) always returns 0 (in my module as in Example module).
  
  I saw a hack by Larsneo in :
  /includes/classes/adodb/drivers/adodb-mysql.inc.php
  and the explanation in:
  /includes/classes/adodb/readme_postnuke.txt
  
  But why using $dbconn->GenId(...) if it always return 0 ???
  
  I need to know the item id I insert in database. How to do that without calling GenId() ?

  You're recommended to use this code becuase certain databases don't have auto-increment fields but use sequences instead. One example is oracle. However mysql has auto-increment fields so the GenID method of adodb has no effect when used on a mysql DB.
  
  If you follow the example module code further you'll see that the inserted id is calculated later using the PO_Insert_ID method.
