Rolling back Transaction Doesn't Work with TpFIB Components

Question

I am using Delphi 2010 with FIB Components like TpFIBDataset, TpFIBTransaction and TpFIBDataset with Firebird database.

I have already set TpFIBDataset's 'AutoCommit' property to 'False', then also when I execute below statement in the try..finally block and rollback the transaction data still get posted.

Code:

FIBDataset.Post;

Below is the sample code.

Code:

try
  FIBDatabase.StartTransaction;

       ....

          Block of Code;

       ...
    finally
      if saveALL then
        FIBDatabase.CommitRetaining
      else
        FIBDatabase.RollbackRetaining;
    end;

Answer 1

The Transaction on the dataset must also be checked and changed

FIBDataset.AutoCommit := false;

You need to Close the query as well. In this case

FIBDataset.Close;
FIBDatabase.Rollback;

EDIT

I would also advise you to allocate the one transaction component to all the datasets (rather than the database). And use the start, commit, rollback methods of the transaction component. Further, you must assign the transaction component before you do any operations.
