I appreciate if anybody can help me to write this UPDATE command. The requirement is to update 3 columns in a table with a subquery accessing same table but different row.
update MY_TAB1
set ( acronym, version)= ( select acronym , version
from MY_TAB1
where Pri_Key=121 )
where Pri_Key=117
This does not work and I do not know how can I update multiple columns at the same time. Thanks.

UPDATE MY_TAB1

   SET acronym = (SELECT acronym

                    FROM MY_TAB1

                   WHERE Pri_Key = 121),

       version = (SELECT version

                    FROM MY_TAB1

                   WHERE Pri_Key = 121)

 WHERE Pri_key = 117

Thanks for your help. This is a round about procedure but I think this is the only to do in SQL Server. In Oracle, it is quite simple.

seems pretty easy in SQL Server as well.

Looks pretty straight forward to me too, though I think I would use variables to hold the values and do a single select to get them. Another statement to update them.
