    78 ExecuteSqlQuery() and ExecuteSqlNonQuery() must use the same underlying connection on which the transaction started. So MgTransaction instance is passed in as parameters for both of these two methods. The MgTransaction implementation can return the undelying connection.

    123 If an MgTransaction has been started but hasn't been committed or rollbacked within the timeout, the transaction will be automatically rollbacked. If you call Commit() or Rollback() after timeout, an exception will be thrown reminding that the transaction has been timeout.

    125 Two items will be added into WebConfig.ini for transaction timeout setting. If the transaction hasn't been committed or rollbacked within thirty minutes, it will be automatically rollbacked.

    132132The transaction has to be bound with the underlying FDO connection where it starts during its life circle. The underlying FDO connection will be kept used by the transaction until the call of either Commit() or Rollback(). The implementation of MgTransaction should be able to return the underlying connection.

    136136This is a new API, so API documentation need to be updated. However, it will not affect the existing application if you don't use it at all.

    138 This new API is designed for sql statement execution. You have to use the API with ExecuteSqlQuery() or ExecuteSqlNonQuery() within the transaction.
