from http://www.ispirer.com/doc/sqlways36/sqlserver/mssql_fn.html:

COALESCE
Syntax


 COALESCE(expr1 {, exprN })  


COALESCE returns the first expression that is not NULL. The expressions are evaluated in the order in which they are specified. This function is usually used to replace NULL values with a not NULL value.

Example

This example selects title and price for all books. If the price for a given title is NULL, the price shown is 0.00.


SELECT title, COALESCE(price, 0.00) AS price
FROM titles;


Equivalents in other databases

 IBM DB2   COALESCE function  
 Oracle   NVL function

coalesce is a much better answer, since you can pass in 2 or 3 or 12 arguments and it returns the first nonnull
