I want to create a query that will subtract a given number from a
value in the database and store it in the same spot the value was. For
example, a customer has a balance of 23.22 which is stored in a
balance column in the database and the user makes a payment of 10.00.
I want a query that will take the 10.00 and subtract it from the
23.22, and store the remainder back in the balance column which
previously stored the 23.22. Is it possible to do in one update
statement? Thanks.

Update MyTable SET Balance = (Balance - 10.00) Where CustomerID =
