I make a copy of a Query into a TClientDataSet.  The Query is:

SELECT DISTINCT NAME, BITS FROM SYNOPTAGS

When I try to edit the data in the TClientDataSet, there is always an
exception:

THE TABLE IS NOT IN EDIT MODE

I use the Edit method and FieldValues property of the TClientDataSet to
edit.

When I saw the CanModify property of the TClientDataSet it is FALSE, in
fact this property changes when I make the copy from the Query.

What can I do to avoid the TClientDataSet gets the Query CanModify
property value?

What happens when you call the Edit method of TClientDataSet? Does this
generate an exception?

I tried to duplicate your problem. I set up a
TQuery-TDataSetProvider-TClientDataset connection. When I set the active
property of the clientdatset to true, I can edit the data without any
problems.
