我已经从azure安装了一个弹性代理。弹性代理在azure中使用db来维护和运行其逻辑。它创建的表列表很长。但这张table正是我要做的。
jobs\u internal.job\u executations(保存弹性作业的每次运行)
dbo.custom\u status(为跟踪执行活动而创建的表)
dml操作将插入dbo.custom\u状态模式的表
CREATE TABLE [dbo].[custom_status](
[Id] [int] IDENTITY(1,1) NOT NULL,
[job_id] [uniqueidentifier] NOT NULL,
[job_name] [nvarchar](128) NULL,
[job_execution_id] [uniqueidentifier] NOT NULL,
[start_time] [datetime] NULL,
[end_time] [datetime] NULL,
[lifecycle] [nvarchar](50) NULL,
[message] [nvarchar](max) NULL,
[exception] [nvarchar](max) NULL,
[column_state] [nvarchar](20) NOT NULL,
[entry_time] [datetime] NULL,
CONSTRAINT [PK_dbo.custom_status] PRIMARY KEY CLUSTERED
(
[Id] ASC
)WITH (STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF) ON [PRIMARY]
) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]
GO
ALTER TABLE [dbo].[custom_status] ADD DEFAULT (getdate()) FOR [entry_time]
GO
当我在jobs\u internal.job\u上引入触发器时,更新、插入、删除
CREATE TRIGGER [jobs_internal].[TR_status_message]
ON [jobs_internal].[job_executions]

AS

触发器工作,但停止基表上的所有其他crud操作/dml操作,从而导致弹性作业不工作并堆积在队列中。
此表上已存在由elasticjob server创建的触发器,并且该触发器不会停止该表的dml操作
因此,我尝试了一个观点
jobs.job使用dml而不是
ALTER TRIGGER [jobs].[TR_job_alert]
ON [jobs].[job_executions]
INSTEAD OF UPDATE
AS
BEGIN
--just to test normal is being triggered
insert custom_status
values (NEWID(),
'testing',
NEWID(),
null,
null,
'test',
null,
null,
'test',
GETDATE());

视图上的触发器永远不会触发!我知道一点点大规模的dml操作不会触发触发器。
我的扳机有问题吗。
如果快速触发器触发,它将阻止表上的所有其他操作
第二个触发器从不触发视图。

尝试删除打印语句。很长的一段时间,但可能是他们造成的挂起,停止未来的处理。
