#257385

I have a table (JeffTest) that has two fields (Encounter, DocType).
How can I get the Encounter that does not have a DocType of '305'?
I'd expect the result to be 27242361 & 27242379.
Sample:
29182805-504
29182805-400
29182805229
29182805231
29182805305
29182805-503
27242361-400
27242361229
27242361-503
27242361231
27242379149
27242379-400
27242379229
27242379231
27242379-503
27242379-403

Hi

SELECT

Encounter

FROM

JeffTest

WHERE

Encounter NOT IN ( SELECT Encounter FROM JeffTest WHERE DocType = 305 )

Great, thanks, I knew it was easy. I'm still learning.

Many Thanks!

Hi
SELECT
Encounter
FROM
JeffTest
WHERE
Encounter NOT IN ( SELECT Encounter FROM JeffTest WHERE DocType = 305 )
Andy

If you only want to see the Encounter value once in the result set, I'd add the DISTINCT keyword to Andy's great response, as follows:

SELECT DISTINCT

Encounter

FROM

JeffTest

WHERE

Encounter NOT IN ( SELECT Encounter FROM JeffTest WHERE DocType = 305 )

Thanks Rob, yes that is needed.

D'oh spot on! Forgot to add the DISTINCT! :Whistling:

Another way

SELECT Encounter

FROM JeffTest

GROUP BY Encounter

HAVING MAX(CASE WHEN DocType = 305 THEN 1 ELSE 0 END)=0

Remember I said I'm still learning?

Can someone show me how to do this without using the temp db (all in one statement)? I know it is a nested select but I'm not clear on the syntax. This solution does work but I want to learn.

Thanks for any insight.

SELECT e.EncounterNo, e.EncntrStartDate, d.DocType, m.MedRecNo, ee.EnrolleeName

INTO #JeffTest --Temp Table

FROM Encounters e (nolock)

JOIN DocsOwners do (nolock) on e.EncntrOwnerId = do.OwnerId

JOIN Documents d (nolock) on do.DocId = d.DocId

JOIN MedicalRecords AS m (nolock) ON e.MedRecOwnerId = m.MedRecOwnerId AND e.MedRecModNum = m.MedRecModNum

JOIN dbo.Enrollees AS ee (nolock) ON m.EnrolleeOwnerId = ee.EnrolleeOwnerId

WHERE EncntrStartDate >= '12/01/2011 00:00:00' and EncntrStartDate &lt= '12/31/2011 23:59:59'

and e.SvcCode= 'EMR'

ORDER BY e.EncntrOwnerId

GO

SELECT DISTINCT EncounterNo, EncntrStartDate, MedRecNo, EnrolleeName

FROM #JeffTest

WHERE

EncounterNo NOT IN ( SELECT EncounterNo FROM #JeffTest WHERE DocType = 305 )

ORDER BY MedRecNo

GO

Hmm, I had to take out the Drop_Temp_Table command from the end to get the 'code' to post.

You can use a CTE

WITH JeffTest AS (

SELECT e.EncounterNo, e.EncntrStartDate, d.DocType, m.MedRecNo, ee.EnrolleeName

FROM Encounters e (nolock)

JOIN DocsOwners do (nolock) on e.EncntrOwnerId = do.OwnerId

JOIN Documents d (nolock) on do.DocId = d.DocId

JOIN MedicalRecords AS m (nolock) ON e.MedRecOwnerId = m.MedRecOwnerId AND e.MedRecModNum = m.MedRecModNum

JOIN dbo.Enrollees AS ee (nolock) ON m.EnrolleeOwnerId = ee.EnrolleeOwnerId

WHERE EncntrStartDate >= '12/01/2011 00:00:00' and EncntrStartDate <= '12/31/2011 23:59:59'

and e.SvcCode= 'EMR'

)

SELECT DISTINCT EncounterNo, EncntrStartDate, MedRecNo, EnrolleeName

FROM JeffTest

WHERE

EncounterNo NOT IN ( SELECT EncounterNo FROM JeffTest WHERE DocType = 305 )

ORDER BY MedRecNo

Actually, it's not always a good thing to try to do everything in a single query. You can end up with accidental many-to-many joins and other performance related problems.

If you end up with a "DISTINCT" in your query, such a problem may exist.

I've converted many a report from a grueling 45 minute run to a 3-8 second run by using Temp Tables and other "Divide'n'Conquer" methods.

How about this option?

SELECT e.EncounterNo, e.EncntrStartDate, d.DocType, m.MedRecNo, ee.EnrolleeName

FROM Encounters e (NOLOCK)

JOIN DocsOwners do (NOLOCK) ON e.EncntrOwnerId = do.OwnerId

JOIN Documents d (NOLOCK) ON do.DocId = d.DocId

JOIN MedicalRecords AS m (NOLOCK) ON e.MedRecOwnerId = m.MedRecOwnerId AND e.MedRecModNum = m.MedRecModNum

JOIN dbo.Enrollees AS ee (NOLOCK) ON m.EnrolleeOwnerId = ee.EnrolleeOwnerId

WHERE EncntrStartDate >= '12/01/2011 00:00:00' AND EncntrStartDate <= '12/31/2011 23:59:59'

AND e.SvcCode= 'EMR'

AND NOT EXISTS (SELECT 1

FROM Encounters a

WHERE a.e.EncntrOwnerId = e.EncntrOwnerId

AND a.DocType = 305

)

brad.mason5 Hall of Fame Points: 3299 More actions · Answer 12

This above option will not work as DocType is not in Encounters. Using not exists is another option I was shooting for.

SELECT e.EncounterNo, e.EncntrStartDate, d.DocType, m.MedRecNo, ee.EnrolleeName

FROM Encounters e (NOLOCK)

JOIN DocsOwners do (NOLOCK) ON e.EncntrOwnerId = do.OwnerId

JOIN Documents d (NOLOCK) ON do.DocId = d.DocId

JOIN MedicalRecords AS m (NOLOCK) ON e.MedRecOwnerId = m.MedRecOwnerId AND e.MedRecModNum = m.MedRecModNum

JOIN dbo.Enrollees AS ee (NOLOCK) ON m.EnrolleeOwnerId = ee.EnrolleeOwnerId

WHERE EncntrStartDate >= '12/01/2011 00:00:00' AND EncntrStartDate <= '12/31/2011 23:59:59'

AND e.SvcCode= 'EMR'

AND NOT EXISTS (SELECT 1

FROM Encounters

JOIN DocsOwners WITH (NOLOCK)

ON Encounters.EncntrOwnerId = DocsOwners.OwnerId

JOIN Documents WITH (NOLOCK)

ON Documents.DocId = DocsOwners.DocId

WHERE Encounters.EncntrOwnerId = e.EncntrOwnerId

AND Documents.DocType = 305

)
