public procedure TSQLTransaction.RollbackRetaining; override; |
RollbackRetaining undoes all changes in the database since the start of the transaction. It can only be executed in an active transaction.
After this, the transaction is kept in an active state. To undo changes and close the transaction, execute Rollback instead.
| Remark: | Changes posted in datasets that are coupled to this transaction will not be undone in memory: these datasets must be reloaded from the database (using Close and Open to reload the data as it is in the database. |
Executing RollbackRetaining when no transaction is active will result in an exception. A transaction must be started by calling StartTransaction. If the database backend reports an error, an exception is raised as well.
