Hi
I am trying to run a report on number of patients who had their BMI checked during last month. (250 patients was seen) how many of them had their BMI checked and how many didn't. When I add the first field which is the patient ID it returns 250 patients but when I add the BMI field the patient ID count changes to 175, I would like to see the 250 patient ID with and without the BMI%
what am I doing wrong?
I am pulling the data from three different Excel cheets. and I'm using Crystal X1
Here is what I would like my report to look like:
Patient ID: BMI%
2222222 25.02
3333333 32.00
4444444
5555555 40.00
But here is what I'm getting:
Patient ID: BMI%
2222222 25.02
3333333 32.00
5555555 40.00
Thanks for your help.

I would think that you would use a left outer join on the data.
select * from allPatients ap LEFT JOIN bmiPatients bp
on ap.patientID = bp.patientID;
in CR you would use the left outer join as the LINK criteria between the 2 tables.

One way I have done for this, to avoid the left join, is to select on
param in ["BMI","BP Diastolic"]
and then use a variable to capture for BMI obtained
if (__ = "BMI") then 1 else 0
The assumption being that people will always have a BP at a visit - and that count can give you the overall denominator.
