There about 25 fields in one table. The fields's name like below.
A, A_NEW, B, B_NEW...and so on.
All data in Fields which named without _NEW is stored data from OrderHistory table and with _NEW stored the data from application user's input.
Is there any fast way to compare data A with A_NEW, B with B_NEW and so on.
As long as find out a difference from any pair, just send out message.
