ADO BeginTrans, CommitTrans, and RollbackTrans Methods

Complete Connection Object Reference

These 3 methods is used with the Connection object to save or cancel changes made to the data source.

Note: Not all providers support transactions.

Note: These 3 methods are not available on a client-side Connection object.

BeginTrans

The BeginTrans method starts a new transaction.

This method can also be used to return a long value that is the level of nested transactions. A top level transaction has a return value of 1. Each additional level increments by one.

CommitTrans

The CommitTrans method saves all changes made since the last BeginTrans method call, and ends the current transaction.

Since transactions can be nested, all lower-level transactions must be resolved before you can resolve higher-level transactions.

RollbackTrans

The RollbackTrans method cancels all changes made since the last BeginTrans method call, and ends the transaction.

Since transactions can be nested, all lower-level transactions must be resolved before you can resolve higher-level transactions.

Syntax

level=objconn.BeginTrans()

objconn.BeginTrans

objconn.CommitTrans

objconn.RollbackTrans
