Interbase 5.6 error and php 4.0.4

I just upgraded to 4.0.4 from 4.0.2 and decided to try to access our Interbase Server data. Here is the code snippet: (I had not tried to access Interbase before the upgrade, so I don't know if 4.0.2 was working) <? require("qc.inc"); $conn = ibase_connect($host,$user,$pwd); echo $conn; $sql = "select * from manufacturer"; $rslt = ibase_query($conn,$sql); $rcd = ibase_fetch_object($rslt); echo $rcd->AIRWAY_BILL; ?> qc.inc has our host, user, and pwd info. The result of $conn is 'Resource id #1' which seems to be a strange link id - I thought it was an integer value? The error is Warning: InterBase: Dynamic SQL Error SQL error code = -901 feature is not supported from the $rslt= line where the actual query is run. Any ideas regarding Interbase would be appreciated - thanks. ________________________ Greg Kelley, IT Director Londavia, Inc.
