结果：

Declare @path nvarchar(255);
Set @path = 'C:\Users\Public\Documents\'

Declare @attachment nvarchar(255);
  Set @attachment = @path + result1 + '.txt' + ',' + @path + result2 + '.txt'

Answer 1

CREATE Procedure [dbo].[GetItems]
@TransNumber INT,
 @attachment nvarchar(MAX)  OUTPUT
AS 

 Begin

 DECLARE @path nvarchar(255);
 SET @path = 'C:\Users\Public\Documents\WineCards\';
 set @attachment = ''


 SELECT @attachment += CONCAT(';', @path, 'wn', ItemLookupcode, '.pdf')
 FROM TransactionEntry
 Left Join Item on TransactionEntry.ItemID = Item.ID
 WHERE TransactionEntry.TransactionNumber=@TransNumber and         dbo.fn_FileExists(CONCAT(@path, 'wn', ItemLookupcode, '.pdf') )=1
 Group by Itemlookupcode

选择@attachment = STUFF（@attachment，1,1，''）; - 删除初始“;”
