Thanks for the response, Rob.<br><br>Interestingly, I have just changed from using the TADOTable objects for adding/deleting/editing the database table data and have instead now implemented those functions in TADOQuery objects.

Hi<br>
<br>
I don't use the ADO components much but it sounds like a caching
issue. I would definately NOT use table methods and do it all from
SQL. Its much cleaner that way and you can see exactly what's going
on, rather than letting a table component do the magic or running
its own queries !<br>
<br>
Cheers<br>

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.<br>
<br>
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. <br>
<br>
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.<br>
<br>
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?<br>

Hi Eric,

<div>With AdoQuery you can try Requery method.</div>

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.<br>
<br>
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.<br>
<br>
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? <br>
