这是我想要做的:

SELECT iif(d.ItemType = 'INVOICE', 0, iif(d.ItemType = 'PACKING', 0, 1)) AS MissingDocuments FROM dbo.DocumentDetails AS D

不幸的是意识到这与MSSQL2008不兼容.所以尝试写一个,IF ELSE但也没有用.

SELECT  IF d.ItemType = 'INVOICE'
   0
ELSE 
   BEGIN
      d.ItemType = 'PACKING'
      0
   ELSE
      1
   END  AS MissingDocuments
FROM  dbo.DocumentDetails AS D 

你能告诉我在这里做错了什么吗？
