Hi all,
Here is the senario, i have a large table with (say 3 million records) when ever there is a change in a particular columns data(update) , a column named "flag" in the same table has to be set to indicate a change for that particular record.
Is trigger the best option here, i am a novice & was facing some problem to figure it out, is there any way using Referintial Integrity concept to replace triggers and improve performance.
