Distinct Count
Hi
We have a client file linked to an appointment file. A client can have
many appointments in a given period. I am trying to figure out how to
count the number of clients who have had an appointment in a given period
but only want to count them once, regardless of how many appointments
they have had. i.e. a distinct count.
Many thanks

How are you accessing this data? Are you using DADE and the Query Designer
or are these just two tables you are accessing in your Delphi app? I
believe you can use an expression such as the following to get a distinct
count in SQL code...
COUNT(DISTINCT ClientNo), granted you are grouping by ClientNo.
