Question

I’m getting an error on my case expression. I just want to evaluate one condition, and return the proper statement. But I keep getting a syntax error near “as”.

Here’s what I have:

left outer join (            
        SELECT wbs1, wbs2, wbs3  
    , case 
            when (ProgramAffiliation = magrann.[programAffiliation_AEP/COHesh2010]()) 
            then '[AEP] as ''AEP1'''
            else [AEP Base] as 'AEP1'
        end
    , [AEP:Non-Compliant Mechanical Ventilation] as 'AEP2'  
    , [AEP - Non Energy Star AC ($90 deduction)] as 'AEP3'  
    , [AEP: Bonus] as 'AEP4'

Answer 1

Your CASE Syntax is wrong. You have a column name enclosed in single quotes and you have the alias in two places (both wrong):

 , case 
    when (ProgramAffiliation = magrann.[programAffiliation_AEP/COHesh2010]()) 
    then '[AEP] as ''AEP1'''  -- <-- don't put the column in single quotes and no alias here
    else [AEP Base] as 'AEP1'  -- < don't put the alias here
   end  -- < the alias goes here

So your CASE should be:

, case 
    when (ProgramAffiliation = magrann.[programAffiliation_AEP/COHesh2010]()) 
    then [AEP]
    else [AEP Base] 
    end as AEP1  

The alias goes after the END in a CASE expression.
