SQL Aggregate functions

Last Modified: 2020-03-27
I am trying to figure out an SQL query to get aggregate calculations from a data table.  The data table is a simple list of dates and data (real).  I am simply trying to get the AVG, MAX, and MIN of the top 100 data points in descending order.  There are several thousand data points in the table.  The Select statement I have used that does not work is:

SELECT TOP 100 Cur_Date, AVG(DataMean) AS DMEAN, MAX(DataMean) AS DMAX, MIN(DataMean) AS DMIN  FROM DataTable WHERE PartNumber = ? ORDER BY Cur_Date DESC.

Can anyone help?

Thanks,
