In this video you'll learn how to work with nulls in your SQL queries. You'll see how to use the IS NULL expression and IsNull function to check for the existence of nulls and how to use the IIf and Switch functions to replace nulls with other values. You'll also see what happens when a null is involved in a calculation and how to make sure that the calculation returns a non-null result.
