case statement

Try another form:

select case 
when AcctType in (43,41,47,85,80,81,66,44) then 'AOP'
when AcctType in (67,18,55, . . .) then 'Others'
. . .

To simplify this, maybe you can replace it with a join with special table.

Hi @Hemant Karnik ，

Welcome to the microsoft TSQL Q&A forum!

Your question is related to tsql, so my colleague helped you add the tsql tag.

Your problem is that you are not familiar with the syntax of the CASE WHEN statement.Please refer to:

    select   
    case when AcctType in (43,41,47,85,80,81,66,44) then 'AOP'  
         when AcctType in (67,18,55,13,21,88,46,14,69,11,20,52,90,42,61,58,74,83,5,37,76,22,15,25,35,91,19,56) then 'Others'  
         when AcctType in (32,84,60,24,12) then 'Corporate'  
         when AcctType in (50,30,4,70,87,82) then 'Trust'  
         when AcctType in (8) then 'HUF'  
         when AcctType in (53) then 'NPO'  
         when AcctType in (71) then 'PEP'else null end   
    from D009022  

There is also an error near your else statement, you can directly omit the ELSE sentence (in this case, the default ELSE NULL), or write the result you want after the ELSE. But you cannot write ELSE END.

Please refer to the two ways of writing CASE WHEN:

    case sex   
       when 1 then 'male'  
       when 2 then 'female'  
       else 'null' end  
      
    case  
    when sex =1 then 'male'  
    when sex = 2 then 'female'  
    else 'null' end  

For more details, please refer to:
CASE (Transact-SQL)
