SELECT cast(100.0 * SUM (CASE Q1 WHEN 'nej' THEN 1 ELSE 0 END) / COUNT(*)
as decimal(5,2)) FROM tbl

Hi erland - thanks for your response- the code works in the way that I dont
get an error - but I dont really know how to get the number of records (in
Field Q1) and the % of these who have the value 'nej' out from this
code..:-(

You can see my Access version of webpage on
http://www.gymnasiereform.dk/svar_q12.asp
here it works fien - but I cant make it work with MY SQL which I'm trying t
migrate to.
Best wishe s- Otto
