hi all,
I have got a table
for example :
"table1" and 3 columns col1,col2,col3.
this table contains too many duplicate rows.

and not having any primary key fields.

insted of using
"select distinct col1,col2,col3 where col1>100"
can anybody suggest other optimized way(I mean insted of using "distinct" or "group by" in sql queries"

thanx in adv

A code example will make it clear. Please come back with your sample data. So that it would be easier to solve it. Good luck :)
