<p class="MsoNormal">I have in interesting problem. We have been successfully using .NET Data Provider 2.1 for a while to select data and never had a problem, however we have never needed to update/insert until recently because we do all that through OpenROAD
Server. Recently my colleague wrote an insert that works fine, but when I copied his approach it always fails. The InsertCommand.ExecuteNonQuery() raises an exception with the message “Connection closed”. When I check the errlog.log on the server, it states
“E_GC4807_CONN_ABORT Aborting client connection, reason follows” and “E_US0005 Could not open the iirelation table”.<o:p></o:p></p>
