Changing column value Normally used to MySQL so need help on syntax check.

with
SELECT * FROM Bit WHERE CustomerID='3512242' I have a field called Filer. I want to change it from a P to a D. Do I use UPDATE to change the value?
UPDATE dbo.Bit
  SET Filer = 'D'
  WHERE CustomerID = '3512242'
  AND Filer = 'P';


Documentation for UPDATE with many examples.
