Question

I need to replace results on up to 9 columns based on one other column value.
If the column “role” is the value “SeniorManagement”, I want to replace what would be default hierarchical values with hard values.
Here’s how I can accomplish this now:

 , CASE
   WHEN d.Role = 'SeniorManagement'  
   THEN (Replace(p.Firstname,'John','Joe')) END as First
 , CASE
   WHEN d.Role = 'SeniorManagement'  
   THEN (Replace(p.Lastname,'TopDog','AssignedPerson')) END as Last
 , CASE...

My question is, is there a less verbose way to combine these?

Pseudo ( I know this doens’t work 🙂

 , CASE
    WHEN d.Role = 'SeniorManagement' 
    THEN (Replace(p.Firstname,'John','Joe')) as First 
    THEN (Replace(p.Lastname,'TopDog','AssignedPerson')) as Last
    THEN (Replace(p.Email,'TopDog@wherever','AssignedPerson@wherever')) as Email

Thanks

Answer 1

what about using a function?

create function dbo.GetColumnValue
(
   @ColumnBasedValue varchar(max),
   @ColumnToReplace varchar(max), --or the type you want
   @ToReplace varchar(max), 
   @Replacement varchar(max)
)
as
BEGIN

return (select case @ColumnBasedValue when 'SeniorManagement'
                      then (Replace(@ColumnToReplace,@ToReplace,@Replacement))
                      else @replaceValue END)

END

and use it like

select dbo.GetColumnValue(d.Role, p.Firstname,'John','Joe') as First, 
dbo.GetColumnValue(d.Role, p.Lastname,'TopDog','AssignedPerson') as Last..
