• 关于云平台的统计分析通用方案


    基本思路:
    使用SQL SERVER 2014的Reporting Services

    定位
    MYSQL用于生产,MS SQL SERVER用于统计分析处理,不占用CPU和IO。


    与MYSQL的关系
    采用链接服务器方式: http://www.cnblogs.com/hukn/archive/2011/07/27/SQL_Server_ODBC_LinkServer_MySQL.html
    创建Link Server
    下面来创建一个与MySQL交互的链接(类似Oracle 的DBLink),在SQL Server 管理器中右键Server Objects 目录下的Linked Servers 点击“New Linked Server”:

    Linked server 链接名称
    Server Type 选择“Other data source”
    Provider 选择“Microsoft OLE DB Provider for ODBC Drivers”
    Product name 填写MySQL 主机地址
    Provider String 填写 Driver={MySQL ODBC 5.1 Driver};Server=10.10.6.199;Database=dsideal_db; User=root;Password=dsideal;Option=3;

    用例 :

    SELECT * FROM OPENQUERY(MYSQL,'select * from dsideal_db.t_base_class')
    INSERT INTO OPENQUERY(Servername,'select * from DBName.tablename') SELECT '1'
    UPDATE OPENQUERY(Servername,
    'select * from DBName.tablename') SET colname='2' WHERE colname='1' SELECT * FROM OPENQUERY(Servername,'select * from DBName.tablename')


    策略
    依托于时间戳TS

    (1)全量: INIT
    按每1000条,从MYSQL读取,然后写入到SQL SERVER。
    直到写入完成。

    (2)增量:  每两小时,从MYSQL通过AGENT定时获取,

    -- 声明一个会话级临时表
    IF object_id('tempdb..#itemtype_temporary') IS NOT NULL
     BEGIN
      DROP TABLE #itemtype_temporary
     END
