We are running SQL Server 2008 on 64bit boxes. We’ve had a request to create a query that has a Where clause that draws data from an Excel table. In pseudo code, the query might look as follows:
Select column1, column2, column3 From MyDatabase.MyTable Where column4 IN (Select all values from column 'A' in SubIDs.xls whose sheet name is 'SubIDs')
It depends how often the data in the XLS changes: if it doesn’t change often, then you can load it into a database table and query it directly. SSIS is a common way to automate this, but there’s no 64-bit OLE DB provider for Jet, so you would need to use 32-bit packages:
Alternatively, you could create a linked server to the Excel spreadsheet and query it directly. See example E here (the same comment about the OLE DB provider applies):
Personally I would load the data into MSSQL first if possible, it’s just much easier.
