Since your table definition did not include any information about keys,
I cannot be sure that this query works:

SELECT a.SSN, a.ResidentProgram, ..., b.IMClinicDay
FROM tblResidentRotations a
LEFT JOIN b tblResidentRotations
ON a.SSN = b.SSN
AND a.IMClinicDateLast = b.IMClinicDateFirst
WHERE a.IMClinicDateFirst >= @yearmonth + '01' AND
a.IMClincDateFirst < dateadd(MONTH, 1, @yearmonth + '01')

I assume that @yearmonth holds the month you are looking for on the
form YYYYMM.
