I also had code working perfectly yesterday and errors today. I have a view pulling data from oracle with an openquery, and a stored procedure using the view with SQL tables. The SP works without the where clause, but errors with "No data found" when the where clause is included. I ended up dumping the view into a temp table first, then using the temp table in the stored procedure and that works. It looks like a problem with date formatting, but who knows why it worked yesterday and not today???
