IngresTransaction Class
The IngresTransaction class represents a local, non-distributed database transaction. Each connection is associated with a transaction. This object allows manual commit or rollback control over the pending local transaction.
Created by the BeginTransaction method in the IngresConnection object. After Commit() or Rollback has been issued against the transaction, the IngresTransaction object can not be reused and a new IngresTransaction object must be obtained from the IngresConnection.BeginTransaction method if another transaction is desired.
