sql - 如何批量修改所有 sql server 代理作业中的作业步骤命令

Question

我有许多工作需要将 1 封特定电子邮件发送到人员列表。该收件人列表在 step 命令中是硬编码的，我需要在所有作业中从该列表中删除一个人。

如何循环遍历 Sql Server 代理中的所有作业并修改命令文本以查找+替换特定的文本。

我正在使用 sql server 2005 并且已经查看了 sp_update_jobStep 但似乎并不是我想要的。

干杯。

Answer 1

您可以尝试直接更新保存 SQL 服务器作业信息的系统表。与您相关的将是：

msdb.dbo.SysJobs
msdb.dbo.SysJobSteps

如果您有特定的电子邮件地址要删除，您可以使用单个 UPDATE 语句更新SysJobSteps表中的Command字段。

UPDATE SJS SET
    Command = REPLACE(Command, 'EmailAddress&TestDomain.Com', '')
FROM msdb.dbo.SysJobs SJ
INNER JOIN msdb.dbo.SysJobSteps SJS
    ON SJS.Job_Id = SJ.Job_Id
WHERE SJ.Originating_server = ..... -- Your server here
    AND SJS.Command LIKE '%EmailAddress@TestDomain.Com%'

建议首先将上述查询作为 SELECT 语句运行，以测试它仅返回您期望更新的作业步骤。

如果有人还在寻找这个，那么下面应该做。不是最好的代码，但可以完成工作。

/*
Replace the below statement with the actual keyword to be replaced:
INSERT INTO SP_Keyword VALUES
('sys.databases3', 'sys.databases5')
,('sysjobs3', 'sysjobs5')

Here we are replacing sys.databases3 and sysjobs3 
with sys.databases5 and sysjobs5 respectively.

Script only searches in 'TSQL', 'Powershell', 'CMDEXEC' job type.
