Empty query result

Hi all. I am querying a database of single information multiple times using a simple 'select' statement. However, whenever the data in the DB is empty or is 0 (zero), then it throws an error. However, I don't want it to throw an error, I just want it to move on to the next query. This is being shown on a webpage I have. Note that I am using a function for this select statement because I just have to change the identifier that I am looking for - saves space. So I don't use mysql_error() to show my errors, I redirect to a global 'error' page. Is there a way to get around this "empty set" problem? Yes, I know about using @ to suppress warnings, but it's more than this. Thanks a bunch, ~Philip
