[DUG] MSSQL DBGrid Refresh

No, I've tried the Requery method and as I understand it the Requery method is effectively doing the same as the Open and Close sequence, i.e. forcing the select statement to be reissued against the database.

For record deletion I call the nbDelete button method on the DBNavigator followed by closing/opening the ADOQuery and that does result in the data being refreshed in the DGBrid.  

For adding and editing records I am using the ADOTable "Append"/"Edit" and "Post" methods on the table followed by closing/opening the ADOQuery (or ADOQuery.Requery) and for some reason (which presently escapes me) the data is not refreshed in the grid.

The question is should I even be using the ADOTable  and would I better off just issuing raw SQL commands via the ADOCommand or similar component?

Hi Eric,
With AdoQuery you can try Requery method.

I am using a DBGrid with an ADOQuery component for display, with modifications to table data (edits, deletes, adds) being done using a ADOTable component.  CRUD operations are done using the table methods rather than raw SQL code.  There's a lot of fields in the database table so coding the operations in SQL would be a pain.



Despite trying to refresh the data in the DBGrid by closing then re-opening both the ADOTable and the ADOQuery component the data in the DBGrid is not updated (unless I exit the application and restart.

I've seen this problem mentioned in various postings but haven't yet seen a solution.  Can someone supply the elusive technique to get the DBGrid data to refresh after the ADOTable data is changed?
