ten round by som nedaval do PHP, ale do SQL:

Select kraj, 
Sum(cs) as SumCS, ROUND(AVG(cs), 1) as PrumCS, 
Sum(era) as SumERA, ROUND(AVG(era), 1) as PrumERA, 
Sum(kb) as SumKB, ROUND(AVG(kb), 1) as PrumKB,
Sum(ge) as SumGE, ROUND(AVG(ge), 1) as PrumGE,
Sum(ra) as SumRA, ROUND(AVG(ra), 1) as PrumRA,
Sum(uc) as SumUC, ROUND(AVG(uc), 1) as PrumUC 
  from banky_bezbarierovost
  group by kraj
  order by kraj

inak co sa ma dosiahnut tymi SUM(cs), SUM(era)? Pretoze to len scita vsetky znamky dokopy. Ak mas 3 riadky s hodnotami 3, 5, 1 tak vysledok bude 9. Predpokladam, ze tam malo ist COUNT - pocet riadkov/znamok.
