SQL Server 2008上的PowerBuilder SQL-在SELECT中具有计算列的CASE语句

Question

I am attempting to create computed columns with a CASE statement using an example from Microsoft .

I will appreciate any help or pointers!!

The relevant example code is:

SELECT   
    ProductNumber, Category =  
      CASE ProductLine  
         WHEN 'R' THEN 'Road'  
         WHEN 'M' THEN 'Mountain'  
         WHEN 'T' THEN 'Touring'  
         WHEN 'S' THEN 'Other sale items'  
         ELSE 'Not for sale'  
    END,  
    Name  
FROM 
    Production.Product  
ORDER BY 
    ProductNumber;  
GO

And I 'think' I am doing the same thing below:

SELECT 
    Convert ( char(10),"") No,   
    Convert ( char(15),"") vendor,   
    car_type.car_type_desc,
    origin_st = 
        case voucher.pu_is_airport
            when 'F' then Convert( char(50),  rtrim(ltrim(operator_archive.pu_st_no)) + " " + rtrim(ltrim(operator_archive.pu_st_name)) )  
            else Convert( char(50), "")  
            end
        origin = 
        case voucher.pu_is_airport
            when 'F' then Convert( char(50),  rtrim(ltrim(operator_archive.pu_city)) + ", " + rtrim(ltrim(operator_archive.pu_county)))  
            else Convert( char(50),  rtrim(ltrim(operator_archive.pu_county))  
            end
         voucher.confirmation_no,   
         voucher.pu_is_airport,   
         operator_archive.dest_st_name  
FROM 
    voucher,   
    car_type,   
    operator_archive  
WHERE 
    (voucher.car_type = car_type.car_type_id) and  
    (operator_archive.confirmation_no = voucher.confirmation_no) and  
    ((dbo.voucher.pu_date_time >= :start_date) AND  
     (dbo.voucher.pu_date_time <= :end_date) AND  
     (dbo.voucher.account_no = :account) AND  
     (dbo.voucher.status_flag not in ('9','X','C','F')) AND  
    (dbo.voucher.payment_type in ('1','2','3','4','5','6','7','8')))    

but the server tells me that I have an error as:

SQLSTATE = 37000
[Microsoft][ODBC SQL Server Driver][SQL Server]Incorrect syntax near 'origin'.

I have tried it with the comma after 'End' and then I get an error stating:

SQLSTATE = 37000
[Microsoft][ODBC SQL Server Driver][SQL Server]Incorrect syntax near 'end'.

Thanks to comments from Lamak, I was able to resolve the issue by adding a missing parenthesis and commas after the 'end' statement. Thanks Lamak!!
