[AccessD] Count of Unique Records

Mark,

The Select statement can be qualified with either Distinct or
DistinctRow.  I am unable to tell you which is the more appropriate for
your situation from the information you provided.

Subject: [AccessD] Count of Unique Records

I have a table with the following records:
John
John
Bill
Bob

I need to find out how many unique records there are.
My current approach is 1 query grouping the above table.
Then, I get a count of grouped records with a 2nd query.

Is there a way to avoid using 2 queries for this?
The above is obviously an example.  The table actually holds thousands
and thousands of records.

Thanks,
