It depends on what you want in your output and how it should be formatted.
If you just need to know all the different classes then you could do this
(assumes Access database):
SELECT DISTINCT [Class] FROM [MyTable];
If you wanted to know how many rows each class contained then you could do
this:
SELECT Count( [Shape] ), [Class] FROM [MyTable] GROUP BY [Class];
