Hi,

Could some one please help me as i got a task which is as follows:

Suppose i am having a table test with columns and data :

C#

ID   Name   Address  Create_date  Update_date
1    abc    india    2013-08-11    NULL
2    xyz    india    2013-08-11    NULL

Now if you see in the above data the update_date is NULL . Now I want that if we update the record at that time it should give me the update_date. For this approach i dnt want to use any Trigger.

For example:

If i updated row for Id=1 then the data should be like this..

C#

ID   Name   Address  Create_date  Update_date
1    abc    US       2013-08-11   2013-08-22

Thanks,
Preetpal Kapoor

Hi, You could use GETDATE() function.

E.g.

SQL

UPDATE Table_Name
SET Update_Date = CONVERT(char(10), GETDATE(),126)
WHERE ID = 1

Solution 2

A defaul constraint only works on inserts, for an update use a trigger

If you don't want to use triggger i think that is not impossible to solve this issue.
