You might want to look at IFNULL or COALESCE. If I recall correctly, IFNULL works for mySQL.
The COALESCE()
function does what you describe. It's standard SQL and it should be supported in all SQL databases.
The IFNULL()
function is not standard SQL. Only some brands of databases support this function.
