Gestionnaire de rapports & Rapports
>>>Thanks for the quick reply Evan. If I do create the SQL cursors in the init event of the DE, how can I set the relations with the main report table? For example, if the main report table has a user ID, and the CURSOR has a user ID and name, how do I set the relationship between the two so that the report shows the user name along with his ID?

I have also used SQL statements to generate a query and then use field names only in the report. That way I can use different Querys and use only one report. In the report fields use for example cust instead of customers.cust for the data source.
James,
I use views when I can, but some of the SQL-selects get pretty huge a complex. There is no way I would want a nasty view like that hanging around. I use the same principle as you. I keep the field names the same as in the original tables. Gives a bit of reuse (a little bit).
The cool thing about putting the SQL statments in the dataenvironment is that you can actuall do a report preview during design.
