It all depends on the type of issue you have with the query execution. Those issues could be anything from no records found to a connection failing. If the problem is something you can test for, which the absence of records would be, you can test for that and present your user with a message stating that no records were found. Even if a connection fails, you should be able to test for that and tell your user.

For issues you cannot test for, depending on the type of application you are writing, you may want to let the application fail and use some framework like ELMAH log and report the error.
