     Posted: 04 Dec 2012 at 9:44am
Hi All,
 
I am a pharmacist and am just learning to use crystal reports. I am trying to create a report of patients that have never had any appointment history. The problem is when I pullup the whole list of patients with no appointment history I am also getting patients that have had appointments but also have one or two blank appointments. How can I eliminate these to get only those patients that have never had any appointments.

can you explain what the difference is between no appintment history at all and 'blank' appointment?
How are your tables set up?
do you have a client/patient table and a seperate appointment table?
if you outer join them you can use an isnull(clientid) on the appointment table.

A blank appoint occurs when a patient does not show up for a visit and "no show" is not chosen and entered in the system, but these patients have had appointments in the past. What I am looking for are only those patients that have never had any appointments at all. I am using a left outer join.

you will either have to use some suppression or modify your query.

if I were doing it, I would probably be lazy and do in crystal

I would group by patient,

create a to find the max(inspection date)

reset on patient

----

I would then go to section expert, in group footer, suppress if that running total <> null

then have the info in details and move it to group footer.

If you need more explanation I am sure Blank will beat me to punch.
