Huseyin Aliz myBiss ApS | Hi All,
In delphi I can clear blob field with field.clear but it seems i cannot do the same in EWB?  Database.StartTransaction;  try      with myDataSet do begin      Update;     Columns['Picture'].clear;      Save;      end;      Database.Commit;      Showmessage('Picture gone!');      except      Database.Rollback;      raise;   end; I've also tried with Columns['Picture'].asString := ''; Same effect. Anyone have an idea? Regards, Hüseyin |

<< In delphi I can clear blob field with field.clear but it seems i cannot do the same in EWB? >> In EWB, BLOB columns are just string columns with links to the underlying BLOB data. Because of this, EWB does not allow one to clear a BLOB column by simply clearing the EWB column. However, I will take a look at this and see if there are any downsides to allowing this type of operation. If not, then I will enable this functionality (currently, EWB just ignores updates to BLOB columns). Tim Young Elevate Software www.elevatesoft.com |

Huseyin Aliz myBiss ApS | Hi Tim,
Thanks for info. So currently only server (module) exists for clearing the blob.
