SQL Union syntax in VBScript?

1,032 Views
Last Modified: 2012-05-11
Experts, I have the 3 following individual queries that I run from VB against SQL.

I'm trying to figure out how to make them a "UNION SELECT" statement, but can't get the syntax right.

Would somebody know how I could update the 3 individual query strings into a single one? - that way I can do a DISTINCT against the query to drop duplicates.

Thanks for any information you can provide.
objRecordSet.Open "SELECT PrinterName, DriverFileName, DriverTextString, ModelNumber FROM " & SQLTable_PrinterMap_Global, _
            objConnection, adOpenStatic, adLockOptimistic


    objRecordSet.Open "SELECT PrinterName, DriverFileName, DriverTextString, ModelNumber FROM " & SQLTable_PrinterMap_Room & " WHERE RoomNumber = '" & ComputerLocation & "'", _
            objConnection, adOpenStatic, adLockOptimistic


    objRecordSet.Open "SELECT PrinterName, DriverFileName, DriverTextString, ModelNumber FROM " & SQLTable_PrinterMap_Computer & " WHERE ComputerName = '" & ComputerName & "'", _
            objConnection, adOpenStatic, adLockOptimistic
