Hi friends

I have table called Customers

CustomerName,Customer_Purchase_Date,Customer_Pay_Date

and Then I have a trigger for it after Update to insert values into

Customer_Audit
CustomerName,Customer_Purchase_Date_New,Customer_Purchase_Date_Old,Customer_Pay_Date_New,Customer_Pay_Date_OLd,


The problem now is that
When the Customer_Purchase_Date for Customer is changed the the old -new values for the Customer_Pay_Date should not change but they are changing and then at one point old and new values are becoming equal in the audit table.


Same is the Case with Customer_pay_Date . If it changes in CUstomer_Table i want to update only the old and new fields of Customer_Pay_Date in the new row of the audit table..


Hope I am clear..Please excuse me if i did not put it nicely...

I usually make "before update" triggers - have you tried this?

Can you post yout trigger code? My guess is you are getting the column from the wrong "special" table (inserted/deleted).

do you mean to say you've separate columns to hold old and new values in audit table?
