See attached query.
The inner SELECT works fine as a standalone query, but when wrapped in the outer SELECT, I get the error "An action query cannot be used as a row source."
I'm running this query on an MDB file from C#.Net, but I get the same results if I copy and paste it into Access 2003 SQL view - there too the inner SELECT works fine, but doesn't work when I wrap it in the outer select. I've also tried removing the final WHERE clause (i.e. the outer WHERE clause) but in all cases, I get the same error message every time I use an outer SELECT.
