Default I need help with SELECT statement - 04-14-2005 , 08:19 PM






Hi, Could you help me modify the SELECT statement below that would
accomplish my final goal.

SELECT col1, col2 FROM table1 WHERE col3 < @V

In col1 rows have many duplicates
col2 has unique values
col3 can have 5 possible values: 5, 10, 15, 20, 25
Variable @V can be equal to 5 or 10 or 15 or 20 or 25

The goal is to:

Return row values from col1 without duplicates, and return corresponding
values from col2 (both col1 and col2 in one row) "WHERE" col3 always has
maximum value from all possible values but is <= @V

Thank you.
Vanessa

I think this will work:

SELECT DISTINCT a.col1, a.col2
FROM table1 a WHERE a.col3 =
(SELECT MAX(col3) FROM table1 WHERE col1 = a.col1 AND col3 <= @V)
