sqlServer 开启CDC

1.为了测试，在容器中启动了一个sqlServer，版本为开发版，注意：只有开发版和企业版才支持cdc

docker run -e "ACCEPT_EULA=Y" -e "SA_PASSWORD=123456aA??" -p 1433:1433 -v /E/docker_data/sqlserverdata:/var/opt/mssql/data --name sqlserver19 -d mcr.microsoft.com/mssql/server:2019-CU2-ubuntu-16.04

账号：sa

密码：123456aA??

2.下载SSMS官方的管理工具

地址：https://download.microsoft.com/download/8/a/8/8a8073d2-2e00-472b-9a18-88361d105915/SSMS-Setup-CHS.exe

 创建连接

3.创建测试数据

create database myDb;
use myDb;
CREATE TABLE [dbo].[test] (
  [id] int  NOT NULL,
  [name] varchar(255) COLLATE SQL_Latin1_General_CP1_CI_AS  NULL,
  [create_time] datetime2(7)  NULL
);

4.开启cdc

-- 为指定的数据库库开启CDC
USE myDb
GO
EXEC sys.sp_cdc_enable_db;

--检查指定的库是否开启CDC,结果为1表示开启了CDC，为0表示没有开启。'myDb'表示要查询的库名，如果要查别的库只需更改库名
SELECT is_cdc_enabled,
       CASE
           WHEN is_cdc_enabled = 0 THEN 0
           ELSE 1
           END status
FROM sys.databases
WHERE NAME = 'myDb';




-- 开启表的CDC
USE myDb
IF EXISTS(SELECT 1 FROM sys.tables WHERE name='test' AND is_tracked_by_cdc = 0)
BEGIN
    EXEC sys.sp_cdc_enable_table
        @source_schema = 'dbo', -- source_schema
        @source_name = 'test', -- table_name
        @capture_instance = NULL, -- capture_instance
        @supports_net_changes = 1, -- supports_net_changes
        @role_name = NULL -- role_name
END

执行建表cdc的时候，可能会报错

消息 22832，级别 16，状态 1，过程 sys.sp_cdc_enable_table_internal，行 673 [批起始行 18]
Could not update the metadata that indicates table [dbo].[test] is enabled for Change Data Capture. The failure occurred when executing the command '[sys].[sp_cdc_add_job] @job_type = N'capture''.

相关解决方案见上

SELECT srvname AS OldName FROM master.dbo.sysservers
SELECT SERVERPROPERTY('ServerName') AS NewName

-- 替换OldName
sp_dropserver '2d6ac68406c4';  
GO
-- 替换NewName
sp_addserver 'bc3a42d3d2f6', local;  
GO  

继续执行cdc

-- 查询表是否开启CDC
SELECT name,
       is_tracked_by_cdc
FROM sys.tables
where object_id = OBJECT_ID('dbo.test');


-- 禁用表的CDC
USE myDb
GO
EXEC sys.sp_cdc_disable_table
     @source_schema = N'dbo',
     @source_name = N'test',
     @capture_instance = N'all'
GO

创建完后 会自动增加视图，系统表等cdc相关的东西
