Updating Numerical Quantities

  • I have a parts table which maintains quantity levels per part.

    If I want to update the quantity for a given part do I have to

    1)T-SQL: SELECT val and load to a variable

    2)whateverlang: do the math and finally

    3)T-SQL:UPDATE tbl SET val.

    Say this was displayed by a web scripting lang.

    Is there a better way? There always is isn't there? Tell me how you'd do it if you want.

    TIA

  • What type of math? Require user input? an example might help.

    If it's simple math, like value * .40, then I'd

    update table

    set colA = ColA *.4

    where pk = xx
