sql-server - SQL 代理作业未将计划从每周更新为每天

Question

以下是最初创建的 SQL 代理作业。后来的要求是将其从每周流程更改为每天流程。所以我更新了作业的调度程序。它成功执行并更新了 SQL 代理作业，但作业没有按时触发。我玩了一下，发现更新调度器并没有更新作业的时间表。

我更新了一些代码，因为我无权发布真实代码。我很抱歉。

USE [msdb]
GO

BEGIN TRANSACTION
DECLARE @ReturnCode INT
SELECT @ReturnCode = 0

IF NOT EXISTS (SELECT name FROM msdb.dbo.syscategories WHERE name=N'[Uncategorized (Local)]' AND category_class=1)
BEGIN
EXEC @ReturnCode = msdb.dbo.sp_add_category @class=N'JOB', @type=N'LOCAL', @name=N'[Uncategorized (Local)]'
IF (@@ERROR <> 0 OR @ReturnCode <> 0) GOTO QuitWithRollback

END

DECLARE @jobId BINARY(16)
EXEC @ReturnCode =  msdb.dbo.sp_add_job @job_name=N'Test for SAJ', 
        @enabled=1, 
        @notify_level_eventlog=0, 
        @notify_level_email=0, 
        @notify_level_netsend=0, 
        @notify_level_page=0,

IF (@@ERROR <> 0 OR @ReturnCode <> 0) GOTO QuitWithRollback
EXEC @ReturnCode = msdb.dbo.sp_add_jobserver @job_id = @jobId, @server_name = N'(local)'
IF (@@ERROR <> 0 OR @ReturnCode <> 0) GOTO QuitWithRollback
COMMIT TRANSACTION
GOTO EndSave
QuitWithRollback:
    IF (@@TRANCOUNT > 0) ROLLBACK TRANSACTION
EndSave:
GO

我使用以下脚本来更新 SQL 代理作业的时间表：

EXEC @ReturnCode = msdb.dbo.sp_add_jobschedule @job_id=@JobId, @name=N'Real test', 
            @enabled=1, 
            @freq_type=4,  ------------------------------------> Daily process
            @freq_interval=1, 
            @freq_subday_type=1, 
            @freq_subday_interval=0,
            @freq_relative_interval=0,
            @freq_recurrence_factor=0, -----------------------> Not used for Daily freq_type, so 0
            @active_start_date=20200427,
            @active_end_date=99991231,
            @active_start_time=10000,
            @active_end_time=235959,
            @schedule_uid=N'<GUID for Schedule>'

今天是 2020 年 4 月 27 日。20200503如果这是每周流程，则以下查询的 next_run_date是正确的日期。这意味着它仍然安排在每周一次，并且没有更新为每天触发。我相信正确的答案应该是20200428。

SELECT next_run_date 
FROM dbo.sysjobschedules
WHERE job_id = '<GUID for Job>'

结果：

------------------------------------------------------------
schedule_id | job_id         | next_run_date | next_run_time|
------------------------------------------------------------
1234        | <GUID for Job> | 20200503      | 0            |
------------------------------------------------------------

我尝试使用 GUI 对其进行更新，并且效果很好。但我只想用脚本更新它。 我如何更新它以每天使用脚本触发它？
