Hi,

How do I compute for the total of the value in Alias vladd1, vladd2, vladd3, vladd4 or any alternative using declare statement ? Here is my sample statement below.

                    
select alan8,                      
case                       
when rtrim(aladd1)  '' then len(aladd1) + 9 else 0 end as vladd1 ,                      
case                      
  when rtrim(aladd1)  '' then len(aladd2) + 9 else 0 end as vladd2 ,                      
case                      
  when rtrim(aladd1)  '' then len(aladd3) + 9 else 0 end as vladd3 ,                      
case                      
  when rtrim(aladd1)  '' then len(aladd4) + 9 else 0 end as vladd4,                      
vladd1 + vladd2 + vladd3 + vladd4 as Total                      
 from Customers                      

Thanks and appreciate your help.

Regards,

Something similar to this?

select alan8,
sum(case when aladd1 > '' then len(aladd1) + 9 else 0 end) as vladd1,
sum(case when aladd2 > '' then len(aladd2) + 9 else 0 end) as vladd2,
sum(case when aladd3 > '' then len(aladd3) + 9 else 0 end) as vladd3,
sum(case when aladd4 > '' then len(aladd4) + 9 else 0 end) as vladd4,
SUM(len(aladd1) + len(aladd2) + len(aladd3) + len(aladd4) + 36) as Total

New code box

There's a new way to format code on the site - the red speech bubble logo will automatically format T-SQL for you. The original code box is still there for XML, etc. More details here.
