Need help in the view script to get the last ward or row - depending on the sequence .

Question

Hi there,

I hv a table , containing data of patient details with ward information and ward seq number.
My requirement is to get the last ward from that view.

Getting the first and second ward . How to get the last ward (TRAN LOUNGE RNS ASB) from this view.?

View script :

WITH CTE as (
SELECT DISTINCT [RESPONSIBLE_OSP_HEALTH_ORG_FULL_NAME]
,[SE_WARD_KEY]
,[SE_CBK_SK]
,[SE_REC_ID]
,[SERVICE_ENC_REC_ID]
,[HEALTH_SERVICE_WARD_NAME] as FIRST_WARD
,isnull(WARD_LOS_MIN,-1) as FIRST_WARD_LOS_MIN
,isnull(LEAD([HEALTH_SERVICE_WARD_NAME],1) OVER (PARTITION BY [SERVICE_ENC_REC_ID] ORDER BY [SE_WARD_SEQ] ASC),'-1') as SECOND_WARD
,isnull(LEAD(WARD_LOS_MIN,1) OVER (PARTITION BY [SERVICE_ENC_REC_ID] ORDER BY [SE_WARD_SEQ] ASC),-1) as SECOND_WARD_WARD_LOS_MIN
,[SE_WARD_SEQ]
FROM table
WHERE SE_WARD_SEQ in (-1,1,2)
)
SELECT * from CTE
WHERE SE_WARD_SEQ in (-1,1)

Hi @ASHMITP
Try this:

WITH CTE as (  
SELECT DISTINCT [RESPONSIBLE_OSP_HEALTH_ORG_FULL_NAME]  
,[SE_WARD_KEY]  
,[SE_CBK_SK]  
,[SE_REC_ID]  
,[SERVICE_ENC_REC_ID]  
,[HEALTH_SERVICE_WARD_NAME] as FIRST_WARD  
,isnull(WARD_LOS_MIN,-1) as FIRST_WARD_LOS_MIN  
,isnull(LEAD([HEALTH_SERVICE_WARD_NAME],1) OVER (PARTITION BY [SERVICE_ENC_REC_ID] ORDER BY [SE_WARD_SEQ] ASC),'-1') as SECOND_WARD  
,isnull(LEAD(WARD_LOS_MIN,1) OVER (PARTITION BY [SERVICE_ENC_REC_ID] ORDER BY [SE_WARD_SEQ] ASC),-1) as SECOND_WARD_WARD_LOS_MIN  
,C.LAST_WARD  
,C.LAST_WARD_LOS_MIN  
,[SE_WARD_SEQ]  
FROM table T CROSS APPLY (SELECT TOP(1)[HEALTH_SERVICE_WARD_NAME] AS LAST_WARD,  
                                       [WARD_LOS_MIN] AS LAST_WARD_LOS_MIN   
						  FROM table ORDER BY [SE_WARD_SEQ] DESC)C  
WHERE SE_WARD_SEQ in (-1,1,2)  
)  
SELECT * from CTE  
WHERE SE_WARD_SEQ in (-1,1)
