Nested SQL case statement

Question

I'm trying to bucket unit statuses. What am I doing wrong with my case statement? I'm new to SQL.

CASE WHEN [sStatus] LIKE '%Notice%'
                THEN 'Notice'
            ELSE 
                CASE WHEN [sStatus] LIKE '%Occupied%'
                        THEN 'Occupied'
                    ELSE 
                        CASE WHEN [sStatus] LIKE '%Vacant%'
                                THEN 'Vacant'
                            ELSE [sStatus]
        END as [Status]

Thank you!

Answer 1

Your case statements are missing ends. But, they don't need to be nested in the first place:

(CASE WHEN [sStatus] LIKE '%Notice%' THEN 'Notice'
      WHEN [sStatus] LIKE '%Occupied%' THEN 'Occupied'
      WHEN [sStatus] LIKE '%Vacant%' THEN 'Vacant'
      ELSE [sStatus]
 END) as [Status]

And, if you just want the first word, you don't need a case at all:

SUBSTRING(sStatus, CHARINDEX(' ', sStatus + ' '), LEN(sStatus))

Answer 2

You are getting the error because you have 3 CASE statements and only one END.

However, there is no need to nest these CASE statements at all. You can simply do this:

CASE 
  WHEN [sStatus] LIKE '%Notice%'
                THEN 'Notice'
  WHEN [sStatus] LIKE '%Occupied%'
                THEN 'Occupied'
  WHEN [sStatus] LIKE '%Vacant%'
                THEN 'Vacant'
  ELSE [sStatus]      
END as [Status]

Answer 3

CASE WHEN [sStatus] LIKE '%Notice%' THEN 'Notice'
     WHEN [sStatus] LIKE '%Occupied%' THEN 'Occupied'
     WHEN [sStatus] LIKE '%Vacant%' THEN 'Vacant'
     ELSE [sStatus] END as Status

You don't need all those else
