How to consolidate duplicate records

Hello,
I'm assigned a task to clean up a table which has the data like below:
col1--col2--col3--col4
103 20 606 $50
103 20 606 $60
I was told to consolidate the sales$ and only keep one record, the primary
key is on col1,col2 and col3.
How can I do this?
Thanks,
SarahWhat about
SELECT col1,col2,col3,sum(col4) as sales
From YourTable
Group by col1,col2,col3

SELECT col1, col2, col3, SUM( col4 ) AS "col4"
FROM tbl
GROUP BY col1, col2, col3 ;
Anith|||Thanks Anith and Jens for your quick response. How could I forget this? I
made a mistake to group by sales column which I should use sum()so it gave
me the wrong result.
Thanks again,
Sarah
