I have a query like this:
(query (sql (:update 'kupci :set 'ime (parameter "ime") 'prezime (parameter "prezime") 'adresa (parameter "adresa")
and I want now for the next parameter to check if something is passed, I tried
(:raw (if (/= (length (parameter "sobnost")) 0) (sql (:set 'sobnost (parameter "sobnost")))))
but it doesn't work. Do I have to use sql-compile maybe ?
