Distinct Selection in SELECT

Hi all, How can I achieve this?
select col1,distinct(col2),col3,col4 from table1
TIAI have no idea what you are trying to achieve.
Please post DDL, sample data and desired results.

You still haven't defined what you want to accomplish. You want one row for
every col2. However, if there are multiple different values for col1 and
col3, you need to define how SQL Server will determine which ones to
include.
If you do not care, say so. "ANY col1 / col3 will do." Maybe one of these
is what your after, though I question the usefulness of the extra columns if
this is the case:
SELECT MAX(Col1), Col2, MAX(col3)
FROM Table1
GROUP BY Col2
(Notice that Col1 will not necessarily come from the same row as Col3, which
is why I asked about the date AND the name that you wanted returned.)
If you do care, say so. Provide REAL specs (not typing out your data in
tabular format) as suggested in http://www.aspfaq.com/5006 (please read in
full, including the link to generate insert statements) and we can provide a
real solution.
A|||great! works for me
Thanks
