我想使用 while 循环并从其他表中逐一迭代值，例如“server1name”、“server2name”、“server3name”，下面是与从 sp 生成 sql 作业相关的代码，这是在 4 个不同的环境中一次创建它我想在 sp 下面使用 while 循环

--use msdb;
--IF  EXISTS (SELECT job_id FROM msdb.dbo.sysjobs_view WHERE name = N'TORODO1')
--EXEC sp_delete_job @job_name = N'TORODO1' , @delete_unused_schedule=1
--DROP PROCEDURE dbo.JobCreation
--sp_helptext 'dbo.JobCreation';
CREATE PROCEDURE dbo.JobCreation
AS
BEGIN
DECLARE @JobName VARCHAR(30)= 'TORODO1';

EXEC    msdb.dbo.sp_add_job @job_name= @jobName, 
        @enabled=0,

您将需要研究Cursors来驱动您的 while 循环。就像是

declare myCursor cursor for
  select servername from ServerTable

open myCursor
fetch next from myCursor into @serverName

while @@FETCH_STATUS = 0
begin
   ... do the work ...
   fetch next from myCursor into @serverName
end

close myCursor
deallocate myCursor

以下是如何使用 while 循环。

SELECT  Servername ,
    0 AS Status 
 INTO    #temp1
 FROM    ServerTable
 DECLARE @variable VARCHAR(50)

WHILE EXISTS ( SELECT TOP 1
                    NULL
           FROM     #temp1 AS T
           WHERE    T.Status = 0 ) 

BEGIN

    UPDATE TOP ( 1 )
            #temp1
    SET     Status = 1
    WHERE   #temp1.Status = 0

    SELECT TOP 1
            @variable = Servername
    FROM    #temp1 AS T
    WHERE   T.Status = 0

...Do your work...

    DELETE  FROM #temp1
    WHERE   #temp1.Status = 1


END
