Quick question... Is all data in SQL-Server...???

Also, you scenario sounds backwards. Typically, production/transaction databases update data warehouses...not the other way around... Please clarify this...

IAC, if you need the power of VFP Cursors, then I would suggest using SPT and stored procedures to actually perform the updates....

I have a data warehouse currently maintained by a VFP 6 application with data that needs to be merged into the existing SQL database. The data warehouse collects data from many different sources and periodically we need to refresh the production SQL database with information collected and stored in the data warehouse.

I'm leaning towards remote views because it is a more familiar way of working with the database, but since there are no controls to bind data to (it's all just programmatically checking each record in the data warehouse, if it exists in production update the production record, if it doesn't exist, insert it into the production database). Any thoughts?
