I have a table that contains a DateTime column, and another column that I want to use as the group indicator.  I haven't found a function that will select the latest or earliest of the DateTime values for each group.  Does one exist?

Thanks

I'm not sure, but will this do what you described?

Latest Date for each group:

Select Group, Max(Date)
From Table
Group By Group


Earliest Date for each group:

Select Group, Min(Date)
From Table
Group By Group

suppose your datetime column is x and other columns are y,z

assing x as getdate() value in your program to get the date of the entry of record in the table.

select y,z,x from tablename order by x desc
