我想提出的if else語句在存儲過程，但沒有找到任何解決方案

Question

我希望把這些條件，我的存儲過程

if ((select PriSubmissionStatusId from Claim where ClaimId = 375)!= 106 ) Print 'Primary' 
else if((select SecSubmissionStatusId from Claim where ClaimId = 375)= 0)print 'Primary' 
else if((select SecSubmissionStatusId from Claim where ClaimId = 375)!= 106)print 'Secoundary' 
else if((select OthSubmissionStatusId from Claim where ClaimId = 375)= 0)print 'Secoundry' 
else if((select OthSubmissionStatusId from Claim where ClaimId = 375)!= 106)print 'Other' 
else print 'Primary' 

爲列名建立起來，他們也是在存儲過程中另一列其中來自不同的桌子。任何想法？

Answer 1

使用Case When，而不是if else

SELECT CASE WHEN PriSubmissionStatusId <> 106 THEN 'Primary' 
      WHEN SecSubmissionStatusId = 0  THEN 'Primary' 
      WHEN SecSubmissionStatusId <> 106 THEN 'Secoundary' 
      WHEN OthSubmissionStatusId = 0  THEN 'Secoundry' 
      WHEN OthSubmissionStatusId <> 106 THEN 'Other' 
     END 
FROM Claim 
WHERE ClaimId = 375
