任何作业完成时执行 SP

Question

我在服务器上有很多 SQL Server 作业。每当完成任何作业执行时，我都需要执行 SP。一种困难的方法是在每个调用该 SP 的作业上创建一个步骤。

有没有简单的方法可以做到这一点？作业完成后，SQL Server 是否执行任何 SP 或任何内容？

Answer 1

我尝试使用简单的存储过程在测试系统上重新创建您的场景。我处理这个问题的方法如下：

1. 创建一个“StartBackgroundProcess”存储过程来启动名为​​“BackgroundProcess”的作业。
2. 创建一个由“BackgroundProcess”作业调用的测试存储过程。
3. 创建一个连续循环的“BackgroundProcess”作业，检查作业是否已完成，然后执行“TestSP”存储过程。
4. 配置“StartBackgroundProcess”存储过程，以便在 SQL Server 启动时调用。

您可以将BackgroundProcess配置为在代码中以任意时间间隔运行，它将检查自上次运行以来已完成的作业（例如每30秒、5分钟等检查一次）。然后它会触发一个测试存储过程，您可以将其替换为您想要使用的任何存储过程。

/*
1. Create a 'StartBackgroundProcess' stored procedure that starts a job named 'BackgroundProcess'.
2. Create a test stored procedure to be called by the 'BackgroundProcess' job.
3. Create a 'BackgroundProcess' job that continuously loops, checking for jobs completed and then executing the 'TestSP' stored procedure.
4. Configure the 'StartBackgroundProcess' stored procedure to be called whenever SQL Server starts.

-- 1. Create the 'StartBackgroundProcess' stored procedure that starts a job named 'BackgroundProcess'.

USE master
GO

IF EXISTS (SELECT * FROM master.dbo.sysobjects o WHERE o.xtype IN ('P') AND o.id = object_id('master.dbo.StartBackgroundProcess'))
DROP PROC StartBackgroundProcess
GO

CREATE PROCEDURE dbo.StartBackgroundProcess
AS
BEGIN
    EXEC msdb.dbo.sp_start_job 'BackgroundProcess'
END
GO


-- 2. Create a test stored procedure to be called by the 'BackgroundProcess' job.

USE Tempdb
GO

CREATE PROCEDURE [dbo].[TestSP]  
AS 
BEGIN
    SELECT 'Running Test', GETDATE()
END
GO


-- 3. Create the 'BackgroundProcess' job that continuously loops, checking for jobs completed and then executing a specified stored procedure.
-- ACTION REQUIRED: Copy/Paste the commented SQL below (up until Step 3) into a new job named 'BackgroundProcess' as a SQL Step and Save. No need to configure a schedule.
-- ACTION REQUIRED: Remove the beginning/ending comment tags from the job!

            DELETE FROM @RunCommand
            SET @i = @i + 1
        END
SET @TimeMarker = GETDATE()
WAITFOR DELAY '000:0:30.000' --Configure this to be the proper frequency for your situation. Ensure it is runs often enough to catch all executions of other jobs.
END

-- 4. Configure the 'StartBackgroundProcess' stored procedure to be called whenever SQL Server starts.

USE master
GO

EXEC sp_procoption 'master.dbo.StartBackgroundProcess', 'startup', 'true' 
GO
