    Hi,

    I have to update a table for following structure...................

    uid RMFP CMFP

    100

    400

    700

    800

    1100

    I want my result as follows...

    uid RMFP CMFP

    1150

    4012

    7180

    8190

    11020

    is there any query by which I can update my table as second form in only one step. Please reply me as soon as possible....

    Thanks in Advance

    Sure. Untested, but this should give you an idea.

    UPDATE SomeTable

    SET RMFP = CASE uid WHEN 1 THEN 15 WHEN 7 THEN 18 WHEN 8 THEN 19 ELSE 0 END,

    CMFP = CASE uid WHEN 4 THEN 12 WHEN 11 THEN 20 ELSE 0 END

    Why's it so important to do it in a single update?
