Concatenating Row Values into 1 Record/String (revisited)

by  NoCoolHandle  Posted    (Edited  )
I discovered this by mistake, but is simplifies a difficult job...
Code: 
  [green]-- Declare a variable to concatinate all the rows into..--[/green]
   Declare @x as varchar(800)
  [green]-- Set a default value that is not null -- [/green] 
   Set @x=''

  [green] -- in the select add the variable to itself and the value in the column and a comma --[/green]
   select @x= @x + cast(OrderId as varchar(200))  
   + ','  from Northwind.dbo.Orders

  [green]-- Retrieve vaules and strip of the last comma--[/green]
  select left(@x,len(@x)-1)
