sql-server-2008 - 多个表的更改数据捕获

Question

SQL Server 2008。是否可以为数据库中的多个相关表创建更改数据捕获（或更改跟踪）？例如多对多关系。

它会是什么样子？

Answer 1

从未使用过它，但从MSDN 文档中我会说：是的！

首先准备数据库：

ALTER DATABASE [yourdb] SET ALLOW_SNAPSHOT_ISOLATION ON

ALTER DATABASE [yourdb]
SET CHANGE_TRACKING = ON
(CHANGE_RETENTION = 2 DAYS, AUTO_CLEANUP = ON)

现在在所需表上启用更改跟踪：

ALTER TABLE [yourdb].[yourschema].[yourtable]
ENABLE CHANGE_TRACKING

查询更改：

IF @sync_initialized = 0
  SELECT * 
  FROM [yourschema].[yourtable] LEFT OUTER JOIN 
  CHANGETABLE(CHANGES [yourschema].[yourtable], @sync_last_received_anchor) CT
  ON CT.[yourkey] = [yourschema].[yourtable].[yourkey]
ELSE
BEGIN
  SELECT *
  FROM Sales.Customer 
  JOIN CHANGETABLE(CHANGES [yourschema].[yourtable], @sync_last_received_anchor) CT
  ON CT.[yourkey] = [yourschema].[yourtable].[yourkey]
  WHERE (CT.SYS_CHANGE_OPERATION = 'I' 
  AND CT.SYS_CHANGE_CREATION_VERSION 
  <= @sync_new_received_anchor)
END
