Querying Access through Excel
Hi,
I have a spreadsheet that exports data into Access.
I used ADO/DAO to do this without a problem.
I am adding more functionality to the spreadsheet and want to be able
to tell if i am going to add duplicate records before they get added.
I want Excel to look at two columns in Access - "Year" and "Month" and
if they are the same as the year and month of the data that I am about
to enter I want a message to pop-up warning me that I could be
entering duplicate information.
I've tries the following:
sSQL = "SELECT * FROM Activity WHERE ([ReportingMonth]=1 AND
ReportingYear]=2004/2005)"
rs.Open sSQL, cn
MsgBox rs.RecordCount
If rs.RecordCount 0 Then MsgBox "duplication possible"
but the problem i come across is that rs.RecordCount displays "-1"
even when i have thousands of records that match the criteria.
Can anyone point out where i am going wrong.
many thanks in advance
