Whats the difference?

Why can I modify data in an Empress database table with data aware controls i.e. DBEdit, DBMemo, but I cannot do it with code i.e. Table1.FieldByName('description').AsString := Edit1.Text;
The table is open with ReadOnly set to false.
the same thing happens with queries even when RequestLive is set to true.
I do not have this problem with Access tables.
Is there anyone else out there using Delphi 3.0 and Empress ?

Sorry, don't know anything of Empress... You do use Edit/post, don't you? But since you don't have problems with Access, I guess you do.

Thanks chaps that sorted the problem, but I still have never had to do this with Access. Empress is a Canadian RDBMS for UNIX, very powerful, checkout

The DataSet must be in edit or insert mode to change a value.  You can use this code to check the status
if MyDataSource.State in [dsEdit, dsInsert] then

The table must be in edit mode (use Table1.Edit; ) and you need to post the changes (use Table1.Post).

You can check if the table is in edit mode by checking the options in the State property (eg: dsEdit and dsIsert).

There is no difference between (as far as BDE is concerned) having data aware controls modify the data and doing it directly through the code.
