SQL中是否有类似的方法可以实现以下目的，但是使用sql server agent作业呢？

这是我为存储过程做的方法。

if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[storedproc]') and OBJECTPROPERTY(id, N'IsProcedure') = 1)
    drop procedure [dbo].[storedproc]
    GO
    CREATE PROCEDURE [dbo].[storedproc] ...

解决方案

尝试这样的事情：

DECLARE @jobId binary(16)

SELECT @jobId = job_id FROM msdb.dbo.sysjobs WHERE (name = N'Name of Your Job')
IF (@jobId IS NOT NULL)
BEGIN
    EXEC msdb.dbo.sp_delete_job @jobId
END

DECLARE @ReturnCode int
EXEC @ReturnCode =  msdb.dbo.sp_add_job @job_name=N'Name of Your Job'

最好阅读有关" sp_add_job"和" sp_delete_job"所需的所有参数的文档

如果我们为作业生成SQL脚本(已通过企业经理测试)，它将自动为我们构建是否存在检查和删除语句。下面的示例：-

DECLARE @JobID BINARY(16)   
DECLARE @ReturnCode INT  
SELECT @ReturnCode = 0  
-- Delete the job with the same name (if it exists)  
SELECT @JobID = job_id   
FROM  msdb.dbo.sysjobs  
WHERE (name = N'My test job')   
IF (@JobID IS NOT NULL)  
BEGIN  
-- Check if the job is a multi-server job  
IF (EXISTS (SELECT *   
FROM msdb.dbo.sysjobservers   
WHERE (job_id = @JobID) AND (server_id <> 0)))   
BEGIN   
-- There is, so abort the script   
RAISERROR (N'Unable to import job ''My test job'' since there is already a multi-server   job with this name.', 16, 1) 
END   
ELSE   
-- Delete the [local] job   
EXECUTE msdb.dbo.sp_delete_job @job_name = N'My test job'   
SELECT @JobID = NULL  
END
