RE: I need help with SELECT statement

Hi Vanessa,

You can try simply this statement if it does'nt matter which values from
col1 you want to take in case qualifying rows have duplicate in col1.

SELECT Col1,Col2 FROM Table1 WHERE Col1 IN
(SELECT DISTINCT Col1 FROm Table1 WHERE Col3<=@V)

We can always tweak this query to perform better as i have used IN here
instead oj join.

Thanks,

Vicky Dhawan
