I need help with a sql query
I am looking for a little help writing a T-SQL query. It's been a while since I've done something like this and my brain is forgetting what I need to do.
I have a table with the following data that I need a query to get Col1, Max(Col2), Min(Col3). So that's for each distinct col1 I want to get the max col2 and min col3.
Example for the table below, I want to see:开发者_开发百科
0001, 1, 01-10-2009
0002, 2, 02-10-2009
0003, 0, 04-10-2009
Col1 Col2 Col3
0001 0 10-10-2009
0001 1 01-10-2009
0002 1 02-10-2009
0002 2 03-10-2009
0003 0 04-10-2009
Thanks!
SELECT COL1, MAX(COL2), MIN(COL3)
FROM table
GROUP BY COL1
