Re: [GENERAL] Calcuate percentage.

select count (*) into t1 from t;
select count(varl), varl into t2 from t group by varl;
select varl, (t2.count*100/t1.count) from t2, t1;

and, of coz, drop tables t1 'n' t2 ;)
(i don't know it's my laminess, but syntax "select ... into TEMP ddd ...
does'n work for me - maybe suggestions? a bug i don't know about?)
