var sidebar_align = 'right';
var content_container_margin = parseInt('290px');
var sidebar_width = parseInt('270px');
I am trying to run following query, but i am getting error:
select Count(Distinct(A||B)) from Tab1;
Can some one please help me to resolve this.
what are you trying to do, select count ( distinct a OR b ) ?
If you're trying to concantenate unique combinations of values for "A" and "B" in the SELECT statement, I don't think that's going to work.
Try SELECT unique A, B, count(*)
GROUP by 1,2
HAVING count(*) > 1 <----- optional, depends on your needs
ORDER by 1,2
