更改几个表的数据捕获

Question

SQL Server 2008. 是否有可能为db中的几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

从来没有使用它，但从MSDN doc我会说：是的！

首先准备分贝：

ALTER DATABASE [yourdb] SET ALLOW_SNAPSHOT_ISOLATION ON 

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

立即启用变化对所需的表（S）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
