you can changing markevozila '%skoda%' (markevozila = 'sve marke' or markevozila '%skoda%'):

select   link_usluge, id_usluge, naslov_usluge, mesto,   deo_grada, adresa, telefon, opis,   naslov_kategorije, kompletno   usluge left join kategorija on koja_kategorija=id_kategorija    naslov_kategorije '%auto mehanicar%'   , mesto '%novi sad%'   , deo_grada '%detelinara%'   , (markevozila = 'sve marke' or markevozila '%skoda%') order    id_usluge desc 

it's important put parentheses around or i've done above - if don't expression won't work properly. let me know if you'd me explain parentheses more - it's long explanation if need i'd happy write up.
