Getting Column Names from an AS400 Database

Can someone tell me why the following code: //---------------------------------------------------- $q = sprintf("SELECT * FROM DB#LIBNAME.TABLENAME"); $conn = new COM ("ADODB.Connection") or die("Cannot start ADO"); $connStr = "Provider=IBMDA400;Password=XXXXXX;User ID=XXXX;Data Source=999.99.1.100;Transport Product=Client Access;SSL=DEFAULT"; $conn->open($connStr); $rs = $conn->execute($q); $outval = odbc_columns($conn, "DB#LIBNAME", "%", "TABLENAME", "%"); //---------------------------------------------------- results in this error being generated on the $outval line? odbc_columns() expects parameter 1 to be resource, object given in D:\WAMP\www\directory\filename.php on line 13 Cheryl L.
