Solution 1

Based on the description you have provided, SQL query never returns an error if no records are returned, because that's a perfectly fine situation.

So if your code raises an error when you get no results from your query, I wouldn't search the problem from the query (taken that it is logically okay not to find any records satisfying the criteria) but search from the code using the results.

Most likely somewhere in your code you ecpect to always have rows in the result set.

Hope this helps.
