Problem with Multiple Table Joins
by DevX Pro
I have two tables Region(RegionId-PK, RegionName) and District(DistrictId-PK, DistrictName, RegionId-FK). When I open a recordset (rs) like : Dim rs as new ADODB.Recordset rs.Open "SELECT District.*, Region.RegionName FROM District INNER JOIN Region ON District.RegionId = RegionId", cn Now, with this recordset, it gives an "Insufficient key column information..." message on rs.Delete method. Moreover, when I update the value RegionId like : rs!RegionId = 3 rs.update The value of 'RegionName' should be updated correspondingly. But it doesn't happen. It will only be updated when I re-query it. But it will be unnecessary extra work and more importantly, the record pointer will be changed on re-query. So could you give me solution to both update and delete problems. Please note that, the same query works well in Access.
