Probs with mysql_db_query and mysql_result

Hello list, I have a Problem with mysql_db_query and mysql_result. The mysql_db_query in the following Code does only work, if i delete the third parameter ($ConnID). Otherwise i get a 'Document contains no data' - Error in the browser. $ConnID = mysql_pconnect("localhost", "root", "password"); $Rs = mysql_db_query("database", "select * from DateiTypen", $ConnID); without a connection-ID it seems to work: $ConnID = mysql_pconnect("localhost", "root", "password"); echo $ConnID . " "; $Rs = mysql_db_query("database", "select * from DateiTypen"); echo $Rs; this gives 'Resource id #1 Resource id #2' as Output. But I can't get a value out of the ResultSet then. The following Code gives a 'Document contains no Data' - Error again: $Value = mysql_result($Rs, 0, "Beschreibung"); echo $Values; Environment: Solaris 7, Apache 1.3.6, php40b3-dev. The same Code works without problems on Linux/Apache 1.3.6/php40b2 against the same mysql-Server. Please help, thanks a lot, Dirk
