Question

I’m using an Access Database that is designed relationally. I have a list of patient IDs in an Excel spreadsheet that I imported and made into a table in Access named importedPatients. There is a related table named Counties that is a one to many relationship for the main Patients table. How can I use the patientIDs present in the importedPatients table to quickly query out information in the related Counties table? Is there an idiomatic way to tackle this?

Answer 1

This will give you county information for each record in importedPatients:

SELECT counties.*
FROM counties INNER JOIN (importedpatients INNER JOIN patients ON
importedpatients.patientid = patients.patientID) ON 
counties.countyid = patients.countyid
