Question

I have this query

SELECT
   T1.Add,
   T1.Edit,
   T1.Usr,
   T2.FirstName,
   T2.LastName 
FROM
   T2 
FULL JOIN 
   T1 ON T1.Usr = T2.Guid

Is it possible to edit this result from DBGrid ?
I want to add Fields T1.Add and T1.Edit to T1 table
if they are not already there
and change their values.

Thanks

Depending on the used components you could use BeforePost (doing your actions and requery), ModifySQL/insertSQL for IBDataSet, OpdateObject TQuery, etc.
Another way would by using ” INSTEAD OF triggers” for a persitant view.
