Re: Report No Data Found

Hi!

That's right, it is possible to use Summary Column with Function = Count and Reset at = Report and then before report trigger.

To check record set before invocation of report with queries that are more then one page I think it is better to use Ref Cursors. In this case you will have a big query in one place. For this you need to create database package with function that returns ref cursor type based on your query, create ref cursor query in Report Designer, then before report invocation use packaged function to initiate cursor variable, fetch it and use attribute %notfound to find out whether result set is not empty. Examples on how to do this can be found in Reports documentation.

Best regards
