CDaoWorkspace::BeginTrans

Call this member function to initiate a transaction.

void BeginTrans( );

Remarks

After you call BeginTrans, updates you make to your data or database structure take effect when you commit the transaction. Because the workspace defines a single transaction space, the transaction applies to all open databases in the workspace. There are two ways to complete the transaction:

  • Call the CommitTrans member function to commit the transaction and save changes to the data source.

  • Or call the Rollback member function to cancel the transaction.

Closing the workspace object or a database object while a transaction is pending rolls back all pending transactions.

If you need to isolate transactions on one ODBC data source from those on another ODBC data source, see the SetIsolateODBCTrans member function.
