Question

Here is the code I’m running into an error with:

FROM
    IndexPID
    INNER JOIN Demographics ON
        IndexPID.NDoc_Number = Demographics.NDoc_Number,
    PatientSupply
    INNER JOIN Demographics ON
        PatientSupply.NDocNum = Demographics.NDoc_Number

I also tried it this way:

FROM
    IndexPID, PatientSupply
    INNER JOIN Demographics ON
        IndexPID.NDoc_Number = Demographics.NDoc_Number
    INNER JOIN Demographics ON
        PatientSupply.NDocNum = Demographics.NDoc_Number

But no cigar. Anybody tell me what I’m doing wrong?

Answer 1

You were very close:

FROM IndexPID
INNER JOIN Demographics 
   ON IndexPID.NDoc_Number = Demographics.NDoc_Number
INNER JOIN PatientSupply
   ON Demographics.NDoc_Number = PatientSupply.NDocNum
