Hi following is a working code
update admin
set [add]= CASE WHEN uname = 'jain' THEN 1 ELSE [add] END
,[edit] = CASE WHEN uname='baiju' THEN 1 ELSE [edit] END
where uname IN ('jain', 'baiju')
this statement is for updating add=1 and edit=1 for users 'jain' and 'baiju'
some times i want to update add=1 for both unames.then i tried this code
update admin
set [add]= CASE WHEN uname = 'jain' THEN 1 ELSE [add] END
,[add] = CASE WHEN uname='baiju' THEN 1 ELSE [edit] END
where uname IN ('jain', 'baiju')
but this is not possible.
how to write the above code using case when. because iam using multiple unames with different fields.
Regards
Baiju

Try

update admin

set [add]= CASE WHEN uname = 'jain' THEN 1 WHEN uname='baiju' THEN 1 ELSE [add] END

where uname IN ('jain', 'baiju')

--OR

update admin

set [add]= CASE WHEN uname = 'jain' OR uname='baiju' THEN 1 ELSE [add] END

where uname IN ('jain', 'baiju')

update admin

set [add]= 1

where uname IN ('jain', 'baiju')

updateadmin
set [add]= CASE WHEN uname = 'jain' THEN 1 ELSE [add] END
,[ADD] = CASE WHEN uname='baiju' THEN 1 ELSE [edit] END
whereuname IN ('jain', 'baiju')

This only gets the unames in Jain and Baiju. So [add] is guaranteed to = 1 only.

Is this what you are after ...

updateadmin

set [ADD] = CASE when uname IN ('jain', 'baiju') THen 1 ELSE [edit] END

I suggest you post create statements for tables and sample data. Also include an explanation of what you want the final output to look like and the business reason for that.
