the number sum(sales) may be too big

possible a very big number got into the system causing the overflow
find it like this:

select max(sales) from tkt_tiket where sdate >= '2009-01-01' and sdate <= '2009-01-31'

or

select sales
from tkt_tiket
where sdate >= '2009-01-01' and sdate <= '2009-01-31'
order by sales desc

select sum(sales) from tkt_tiket where sdate >= '2009-01-01' and sdate <= '2009-01-31' and sales is not null
