max value based on two columns

(OP)
Greetings,

I'm stuck on a simple query to find max values, I'm looking for the max number in col1 based on the values in col2.  I keep getting all values.  I thought it was as simple as:

select max(col1), col2 from table;

I've tried subqueries with a similar result.  Help is always greatly appreciated.

Thanks,
JustATheory

col1    col2
10    3333
15    3333
5    4444
6    4444
7    4444

expected result

col1    col2
15    3333
7    4444
 

RE: max value based on two columns

Try:

CODE

SELECT col2, MAX(col1)
FROM my table
GROUP BY col2;
