If I've a table like above, how do I make a query to get rows count that
doesnt have '*' in it.
Can we have other queries than this : Select count(c) from tablename
where c !='*';
or Select count(c) from tablename where c <> '*';

howabout:
select sum(case when c = '*' then 0 else 1 end) as count_not_star from
tablename
If you want to process all records but only count thouse without a * in c
then this will do the trick.
