Dear Code Masters,

I believe all you you are doing fine and in good health.

i want to insert some record from table "REGIMEN" to table "Common_HIVQ" and i use the statement below :

INSERT INTO Common_HIVQ (PatientIdentifier,VisitID,VisitDate,code14,codedesctxt15)
SELECT patientIdentifier,visitid32,visitdate33,code34,codedesctxt35 FROM Regimen WHERE VisitDate33 <> Common_HIVQ.VisitDate

but i get the following error "

Msg 4104, Level 16, State 1, Line 3

The multi-part identifier "Common_HIVQ.VisitDate" could not be bound.

please i have done every thing to correct this error but to no result. Kindly help me
