Hi,

I would like to be able to update fields in a table and I believe that the following code will make the changes but I am not sure how to code the update to apply it to the table. Value1 forms part of a primary key

      DECLARE @NewCheckDigit INT
      DECLARE @Value1 VARCHAR(14)

      IF SUBSTRING(@Value1 ,3,1) = '9'
            BEGIN
                  SET @et_Processed = SUBSTRING(@Value1 ,3,11)
            END;
      ELSE
            BEGIN
                  SET @et_Processed = SUBSTRING(@Value1 ,3,6) + RIGHT(@Value1 ,5);
            END;

      SET @NewCheckDigit = (CONVERT(BIGINT,@et_Processed) % 7) + 1

      IF SUBSTRING(@Value1 , 3,1) = '9'
            BEGIN
                  SET @Value1  = @Value1  + @NewCheckDigit
            END;
      ELSE
            BEGIN
                  SET @Value1  = STUFF(@Value1 ,9,1,@NewCheckDigit)
END:

Any help would be appreciated
Thanks
