I am creating an access database query and I need to add a field that will have a running count for each employee.

This is what I have
Gary  1-5-07
Gary  1-12-07
Gary  1-19-07
Jeff    1-12-07
Jeff    1-19-07
Bob   1-5-07
Bob   1-12-07
Bob   1-19-07

and this is what I need:

Gary  1-5-07    1
Gary  1-12-07  2
Gary  1-19-07  3
Jeff    1-12-07  1
Jeff    1-19-07  2
Bob   1-5-07    1
Bob   1-12-07  2
Bob   1-19-07  3

I can't figure out what to do here...

Thanks a lot,
Bonnie

Would any user have two entries for the same date?

Jerryb,

No, the dates are distinct per employee.

I am going to try GrayL's idea now

GRayL solution is ok, but with big tables, are slow because he use fields of external query into subquery.

If yours tables are bigs try this
SELECT a.Name, a.MyDate, count(b.Name) from FROM myTable AS a inner join myTable AS b on
a.Name = b.Name and b.MyDate<=a.MyDate group by a.Name, a.MyDate;
It is the same but converting to join isntead subquery.

Do you mean 'Group By' or 'Order By'?

Bonnie_K:,

Why not do this in a Report?

Report TextBoxes have a "Running Total" property, that you can set to Over Group or Over All.

So if you grouped your Report by Name you would select "Over Group"

Is this what you wanted?
