O osluk author Is there a way to define a search so the when sorting by a field records in which this field is null are excluded? For example this is sorting by the year 2000 price http://www.bordeauxreport.com/db-2006-view...+en+primeur+GBP Also Currently 36 2000 prices are zero. (This has been altered I have left only 3 zero values for testing purposes). Currently 161 2000 prices are null. Clearly these all need to be unified but I cannot see how to filter by a null field. Any insights gratefully received. Cheers Chris

	Chris, use COALESCE MySQL function to convert NULL values to 0 I.e. modify your SQL query this way: select ... COALESCE(price,0) as price, ...
