Is this for reporting? If you're using {SSAS Tabular, Excel, or PowerBI} then DAX is baked right in. "Use the force, Luke!"

Split the datetime column into two columns, one for the date, and another one for the time. Then your calendar table will work. And you can create a time dimension...

You can go to the FILTERS section in SSRS and add additional filters for your report. (And add parameters etc). So the "raw" dataset could pull say 100 records, and...

looks okay if you're talking about the basic design. What did you intend to do with it?

Why not a separate table for each?

that's what I realized a little bit ago.

I need all the patient ids returned but no duplicates, only the record that has the highest ProcedureCodeId.

SELECT PatientID, MAX(ProcedureCodeID) AS MaxCodeID

FROM t

GROUP BY PatientID

If you need other columns too,...

Use CROSS APPLY to return the first record

SELECT p.PatientID...

ca.ProcedureCodeID

FROM Patient p

CROSS APPLY (SELECT TOP 1 ProcedureCodeID

FROM SomeTable t

WHERE t.PatientID = p.PatientID

ORDER BY <some column>) ca

Case closed.

Good luck!
