Hi All,

I have a table called Patients with the following fields:

PatientID,

LastName,

FirstName,

InsuranceID,

Balance

There isanother table called Collector with the following fields:

InsuranceID,

CollectorName,

PatientRange – This column contains range using the first character of Patient’s Last Name. For example, A – C, which means this collector is responsible forpatients whose last name begins with A B or C..

Any idea howto join the two table? The join should include InsuranceID and Patient name/range.Thanks in advance for you help!

Does every patient have an InsuranceID? And are all InsuranceIDs in the second table? If so, just let QlikView do the join on InsuranceID for you.

Try something like this:

Paitient:

InsuranceID & '-' & left(LastName,1) as link

Collector:

InsuranceID & '-' & PatientRange as link

Edit:

Just saw that the field holds A-C not A B C.

What you could do is create a flag depending on the ranges. If you have a fixed amount you can do an if statement to do like

if(PatientRange='A-C',1,

if(PatientRange ='D-F',2,

ETC.

and do match in the paitent table like

if(match( left(LastName,1),'A','B','C'),1

if(match( left(LastName,1),'D','E','F'),2
