    I have a phone field I need to validate. I need to remove periods, commas, dashes from the phone numbers.

    Does anyone know how to write this query?

    Thanks,

    Ninel

    A simple approach would be to just use the REPLACE function nested like below.

    select replace(replace(replace(@phone, '.', ''), '-', ''), ',', '')

    store this in a function on the server and reuse in your query...

    No need for a function if you want to permanently correct the data...

     UPDATE yourtable

        SET phonenumbercol = REPLACE(

                             REPLACE(

                             REPLACE(

                             REPLACE(

                             REPLACE(

                             phonenumbercol

                             ,',','')

                             ,'-','')

                             ,'.','')

                             ,'(','')

                             ,')','')

    RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
    First step towards the paradigm shift of writing Set Based code:
    ________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.
