Re: statement stuck when the connection grew up to 45 or more - Mailing list pgsql-bugs

This is the statement which having problem:
     select count(distinct empno) as counter1 from pay_master_history
           where empno in (select empno from pay_batch_basic_history where
organizationid like '015003%')
     and processyear = '2006'
     and processmonth = '05'
     and processbatch = '1'

SELECT COUNT (*) FROM (
SELECT empno as counter1 from pay_master_history as a
INNER JOIN (select empno from pay_batch_basic_history where organizationid
like '015003%'      and processyear = '2006'
     and processmonth = '05'
     and processbatch = '1') as b
ON b.empno = a.empno ) as count_result
-----------------------------
or just create the view and use inner join then count :b
