Hi guys,

I am wondering if you could help.  I am using a TSQLClientDataSet to pull data from several tables.  I have added two additional columns to the TSQLClientDataSet and you like to add data to these columns once the initial retrieve has occurred.  Any ideas on how to do this?  

Cheers,
Paul

Hi Paul,

You can update a TClientDataSet just like a TTable,
if your using DB controls then its easy and use TDataSource, otherwise by code just goto the row you want and update the Data.

For Updating a row Use :

FClientDataSet.Edit;
FClientDataSet[ColName] := Value;
FClientDataSet.Post;

For Adding a row and editing it Use :

FClientDataSet.Append;
FClientDataSet[ColName] := Value;
FClientDataSet.Post;

(Note : FClientDataSet[ColName] is the same as FClientDataSet.Fields[ColName]  )

Keep one thing in mind. If you are creating a CDS with data from a join or union, you can add data to that CDS as shown above, but you CANNOT .applyupdates, so the data you add cannot post to the server.
