如何在SQL Server中動態地傳遞服務器名稱

Question

SET NOCOUNT ON; 

DECLARE @sql NVARCHAR(MAX), 
     @servername NVARCHAR(255) 

SET @servername = '[s-printstream]' 

--Drop Table #Actual 
CREATE TABLE #Actual 
(
    jobnumber INT, 
    firstNameCounts VARCHAR(25), 
    lastNameCounts VARCHAR(25), 
    address1Counts VARCHAR(25), 
    address2Counts VARCHAR(25), 
    cityCounts VARCHAR(25), 
    stateCounts VARCHAR(25), 
    zipCounts VARCHAR(25), 
    inHomeDateCounts VARCHAR(25) 
) 

SET @sql = 'INSERT INTO #actual (jobnumber,firstNameCounts,lastNameCounts , address1Counts, address2Counts, cityCounts, stateCounts, zipCounts, inHomeDateCounts) ' 
SET @sql = @sql + ' Select s.jobnumber, count(s.firstName) AS [firstNameCounts], Count (s.lastName) AS [lastNameCounts], Count (s.Address1) As [address1Counts], Count (s.address2)-Count (address2) AS ' 
SET @sql = @sql + ' [address2Counts], Count (s.City) AS [cityCounts], Count (s.State) AS [stateCounts], Count (s.Zip) AS [zipCounts], Count (jb.inHomeDate) AS [inHomeDateCounts] ' 
SET @sql = @sql + ' From' + ' @servername ' + '.[tdis_417133]' + '.[dbo].[tblStandardFinal] s ' 
SET @sql = @sql + ' INNER JOIN [s-printstream].[tdSchedule2].[dbo].[tblJobTicketActions] jb ' 
SET @sql = @sql + ' ON jb.psFlagJobNumber = s.jobNumber ' 
SET @sql = @sql + ' where jobNumber = @jobNumber ' 
SET @sql = @sql + ' group by jobNumber ' 

PRINT @SQL 

EXEC sp_executesql @sql 
    ,N'@JobNumber Varchar(25)' 
    ,@JobNumber = 417133 

任何人都可以請幫我瞭解如何動態地傳遞我的服務器名稱以及數據庫名稱？當我嘗試去做，我得到這個錯誤：

Msg 137, Level 15, State 2, Line 1
Must declare the scalar variable "@servername"

任何幫助表示讚賞。

感謝

或通過@servername值轉換成SQL命令

EXEC sp_executesql @sql 
    ,N'@JobNumber Varchar(25),@servername nvarchar(255)' 
    ,@JobNumber = 417133,@servername=@servername
