SQL - Finding the minimum value for each distinct record..

Hi All,

I have a table looks like this in SQL Server

Product Sale Date
A date
A date
A date
B date
B date
C date
C date
C date

I would like to write a query to find the minimum date (i.e. the date
of the first sale) for each product

Thus, the expected output would be

Product Sale Date
A min date
B min date
C min date

How can i do this using SQL Server??

any help is greatly appreciated!

Thanks!
