如何手动禁用表的 CDC?

发布于 2024-08-13 10:42:30 字数 229 浏览 4 评论 0原文

在为此禁用 CDC 之前我删除了一个表。现在,当我重新创建表并尝试启用 CDC 时,它表示捕获实例已存在。我可以使用不同的捕获实例名称,但需要知道是否可以手动删除关联的捕获实例。

当我通过 SSMS GUI 删除表时,它也会删除 CDC 表。但这次我使用代码删除了该表,并且它没有禁用或删除 CDC。因此就有了麻烦。 Ms 文档讨论了如果更改表被错误删除的热修复。但我已经删除了基表。有关如何删除已删除表的此捕获实例的任何线索?

I dropped a table before disabling CDC for that. Now when I recreated the table and tried enabling CDC it says that capture instance already exists. I can use a different Capture Instance name but need to know if there is anyway to drop the associated capture instance manually.

When I delete a table through SSMS GUI it drops CDC tables too. But this time I dropped the table using code and it didn't disable or remove CDC. Hence the trouble. Ms documentation talks about a hot fix if Change Table are removed by mistake. But I have removed the base table. Any clues on how to remove this capture instance for the dropped table?

以下是我在 CDC 中删除孤立捕获实例所采取的步骤:

DROP FUNCTION [cdc].[fn_cdc_get_net_changes_dbo_(tablename)]
DROP FUNCTION [cdc].[fn_cdc_get_all_changes_dbo_(tablename)]

然后运行以下命令:

declare @objid int
set @objid = (select object_id from cdc.change_tables where capture_instance = 'your orphaned capture instance')

delete from cdc.index_columns where object_id = @objid
delete from cdc.captured_columns where object_id = @objid
delete from cdc.change_tables where object_id = @objid

此时,您应该能够正常通过 sp_cdc_enable_table 重新创建捕获实例。

Here are the steps I took to remove an orphaned capture instance in CDC:

DROP FUNCTION [cdc].[fn_cdc_get_net_changes_dbo_(tablename)]
DROP FUNCTION [cdc].[fn_cdc_get_all_changes_dbo_(tablename)]

Then run the following:

declare @objid int
set @objid = (select object_id from cdc.change_tables where capture_instance = 'your orphaned capture instance')

delete from cdc.index_columns where object_id = @objid
delete from cdc.captured_columns where object_id = @objid
delete from cdc.change_tables where object_id = @objid

At that point you should be able to re-create your capture instance via sp_cdc_enable_table as normal.

除了 pdanke 的回复之外,我还必须执行一个步骤:

DROP TABLE cdc.<capture_insance>_CT

当我恢复启用了更改数据捕获的数据库时,可能会出现我的 cdc 孤儿。就我而言,

EXECUTE sys.sp_cdc_help_change_data_capture 

导致其中 source_schemasource_table 均为 NULL 的一个条目。

I had to execute one more step in addition to the REPLY by pdanke:

DROP TABLE cdc.<capture_insance>_CT

My cdc orphan may have come about when I restored a database where change data capture had been enabled. In my case,

EXECUTE sys.sp_cdc_help_change_data_capture 

resulted in one entry where source_schema and source_table were both NULL.

嗯,我想出了一个办法。我从所有 CDC 系统表中删除了与该表相关的所有记录,并尝试使用相同名称重新创建捕获实例。成功了!

Well I figured out a way. I removed all the records related to that table from all CDC system tables and tried recreating the capture instance with same name. It worked!

很简单

只需使用以下脚本

EXEC sys.sp_cdc_disable_table 'schema_name','Source_Table_Name','CDC_Table_Name'

It's Simple

Just use the following Script

EXEC sys.sp_cdc_disable_table 'schema_name','Source_Table_Name','CDC_Table_Name'
