Hi,

I have th efollowing select queries which am trying to union together. When I ran the select statements separetely I receive a total number of 56 records.

However, when I enter the UNION instead of getting 56 records I receive 51 records. Any help please

SELECT		dbo.viewCase.CaseID, dbo.viewCase.StudyID, dbo.viewCase.PracticeID, dbo.viewCase.PatientID, dbo.viewCase.TreatmentAssignmentID, 
			dbo.viewCase.NotEligible, dbo.viewCase.VisionID, dbo.viewForm.FormStatusName, dbo.viewForm.FormTypeID, 
			dbo.viewForm.SubmittedDate, 
			dbo.viewCase.OptedOut, dbo.viewCase.NotConsented, dbo.viewCase.PracticeCode, dbo.viewForm.FormStatusID
FROM		dbo.viewForm INNER JOIN
			dbo.viewCase ON dbo.viewForm.CaseID = dbo.viewCase.CaseID
WHERE		(dbo.viewCase.NotEligible = 'True') AND (dbo.viewForm.FormTypeID IN (1, 2)) AND (dbo.viewForm.SubmittedDate IS NOT NULL)
			and dbo.viewForm.FormStatusID in (2)
UNION
SELECT		dbo.viewCase.CaseID, dbo.viewCase.StudyID, dbo.viewCase.PracticeID, dbo.viewCase.PatientID, dbo.viewCase.TreatmentAssignmentID,

FROM		dbo.viewForm INNER JOIN
			dbo.viewCase ON dbo.viewForm.CaseID = dbo.viewCase.CaseID
WHERE		(dbo.viewCase.OptedOut = 'True') AND (dbo.viewForm.FormTypeID IN (1, 2)) AND (dbo.viewForm.SubmittedDate IS NOT NULL)
			and dbo.viewForm.FormStatusID in (2)
UNION

Probably due to duplicates.
Try with
union all

Cursors are useful if you don't know sql.
SSIS can be used in a similar way.

why you need UNION? wont below suffice?


SELECT		dbo.viewCase.CaseID, dbo.viewCase.StudyID, dbo.viewCase.PracticeID, dbo.viewCase.PatientID, dbo.viewCase.TreatmentAssignmentID, 
			dbo.viewCase.NotEligible, dbo.viewCase.VisionID, dbo.viewForm.FormStatusName, dbo.viewForm.FormTypeID, 
			dbo.viewForm.SubmittedDate, 
			dbo.viewCase.OptedOut, dbo.viewCase.NotConsented, dbo.viewCase.PracticeCode, dbo.viewForm.FormStatusID
FROM		dbo.viewForm INNER JOIN
			dbo.viewCase ON dbo.viewForm.CaseID = dbo.viewCase.CaseID
WHERE		(((dbo.viewCase.NotEligible = 'True' OR dbo.viewCase.OptedOut = 'True' OR dbo.viewCase.NotConsented = 'True' ) AND (dbo.viewForm.FormTypeID IN (1, 2))) OR (dbo.viewCase.TreatmentAssignmentID IS NOT NULL AND dbo.viewForm.FormTypeID IN (1)))

AND (dbo.viewForm.SubmittedDate IS NOT NULL)
			and dbo.viewForm.FormStatusID in (2)

ok, Vishakh16 - in your query I receive 51 records instead of 56 - Union all gave me 56 records.

Vishakh16 anyway I can update your more simplified query to extract 56 records?

Thanks

hmm..are you using DISTINCT? unless you do that, I think it should all 56 records. can you post the missing records here?
