Subj:   Re: IN clause limt
From:   Joerg Mutsch

Hi Shijo,

it's not elegant but this should work

     select sum(counts) total_number from
     select column1, count (*) as counts from tablename1
     inner join
     column1 from tablename2 where condition
     group by 1) as tablename2
     on tablename1.column1 = tablename2.column1
     group by 1
     ) tablename3

Note: the group by in the derived table is related for avoiding double countings (in case you have)

Hope this helps.
