Oracle物化视图简介及实战

 

1.1.1             Oracle物化视图简介

1.     物化视图说明

物化视图 (Materialized View)，在以前的Oracle版本中称为快照(Snapshot)。Oracle 的物化视图提供了强大的功能，可以用于预先计算并保存表连接或聚集等耗时较多的操作的结果，这样在执行查询时，就可以避免进行这些耗时的操作，而从快速地得到结果： 物化视图有很多方面和索引很相似： 使用物化视图的目的是为了提高查询性能 物化视图对应用透明，增加和删除物化视图不会影响应用程序中SQL语句的正确性和有效性 物化视图需要占用存储空间 当基表发生变化时，物化视图也应当刷新 物化视图可以分为以下三种类型： 包含聚集的物化视图 只包含连接的物化视图 嵌套物化视图 物化视图可以进行分区。而且基于分区的物化视图可以支持分区变化跟踪（PCT）。具有这种特性的物化视图，当基表进行了分区维护操作后，仍然可以进行快速刷新操作。对于聚集物化视图，可以在GROUP BY列表中使用CUBE或ROLLUP，来建立不同等级的聚集物化视图

 

2.     物化视图详细说明

1.       refresh [fast|complete|force] 视图刷新的方式: fast: 增量刷新.假设前一次刷新的时间为t1,那么使用fast模式刷新物化视图时,只向视图中添加t1到当前时间段内,主表变化过的数据.为了记录这种变化，建立增量刷新物化视图还需要一个物化视图日志表。create materialized view log on （主表名）。 complete:全部刷新。相当于重新执行一次创建视图的查询语句。 force: 这是默认的数据刷新方式。当可以使用fast模式时，数据刷新将采用fast方式；否则使用complete方式。 2.MV数据刷新的时间： on demand:在用户需要刷新的时候刷新，这里就要求用户自己动手去刷新数据了（也可以使用job定时刷新） on commit:当主表中有数据提交的时候，立即刷新MV中的数据； start ……：从指定的时间开始，每隔一段时间（由next指定）就刷新一次；   物化视图可以分为以下三种类型：包含聚集的物化视图；只包含连接的物化视图；嵌套物化视图。三种物化视图的快速刷新的限制条件有很大区别，而对于其他方面则区别不大。创建物化视图时可以指定多种选项，下面对几种主要的选择进行简单说明： 创建方式（Build Methods）：包括BUILD IMMEDIATE和BUILD DEFERRED两种。BUILD IMMEDIATE是在创建物化视图的时候就生成数据，而BUILD DEFERRED则在创建时不生成数据，以后根据需要在生成数据。默认为BUILD IMMEDIATE。 查询重写（Query Rewrite）：包括ENABLE QUERY REWRITE和DISABLE QUERY REWRITE两种。分别指出创建的物化视图是否支持查询重写。查询重写是指当对物化视图的基表进行查询时，Oracle会自动判断能否通过查询物化视图来得到结果，如果可以，则避免了聚集或连接操作，而直接从已经计算好的物化视图中读取数据。默认为DISABLE QUERY REWRITE。 刷新（Refresh）：指当基表发生了DML操作后，物化视图何时采用哪种方式和基表进行同步。刷新的模式有两种：ON DEMAND和ON COMMIT。ON DEMAND指物化视图在用户需要的时候进行刷新，可以手工通过DBMS_MVIEW.REFRESH等方法来进行刷新，也可以通过JOB定时进行刷新。ON COMMIT指出物化视图在对基表的DML操作提交的同时进行刷新。刷新的方法有四种：FAST、COMPLETE、FORCE和NEVE*。**ST刷新采用增量刷新，只刷新自上次刷新以后进行的修改。COMPLETE刷新对整个物化视图进行完全的刷新。如果选择FORCE方式，则Oracle在刷新时会去判断是否可以进行快速刷新，如果可以则采用FAST方式，否则采用COMPLETE的方式。NEVER指物化视图不进行任何刷新。默认值是FORCE ON DEMAND。 在建立物化视图的时候可以指定ORDER BY语句，使生成的数据按照一定的顺序进行保存。不过这个语句不会写入物化视图的定义中，而且对以后的刷新也无效。 物化视图日志：如果需要进行快速刷新，则需要建立物化视图日志。物化视图日志根据不同物化视图的快速刷新的需要，可以建立为ROWID或PRIMARY KEY类型的。还可以选择是否包括SEQUENCE、INCLUDING NEW VALUES以及指定列的列表。 可以指明ON PREBUILD TABLE语句将物化视图建立在一个已经存在的表上。这种情况下，物化视图和表必须同名。当删除物化视图时，不会删除同名的表。这种物化视图的查询重写要求参数QUERY_REWRITE_INTEGERITY必须设置为trusted或者stale_tolerated。 物化视图可以进行分区。而且基于分区的物化视图可以支持分区变化跟踪（PCT）。具有这种特性的物化视图，当基表进行了分区维护操作后，仍然可以进行快速刷新操作。对于聚集物化视图，可以在GROUP BY列表中使用CUBE或ROLLUP，来建立不同等级的聚集物化视图。

4.     物化视图授权

SQL> GRANT CREATE MATERIALIZED VIEW TO scott;   --授予创建物化视图的权限(必须) SQL> GRANT QUERY REWRITE TO scott; --实现查询重写权限，可无 SQL> GRANT ALTER ANY MATERIALIZED VIEW TO scott; --修改物化视图的权限，可无 SQL> GRANT LOCK ANY TABLE TO SCOTT;  --可无 SQL> GRANT CREATE SESSION TO SCOTT;  --可无, SCOTT用户刷新物化视图

5.     物化视图语法

CREATE MATERIALIZED VIEW <schema.name> PCTFREE <integer> PCTUSED <integer> TABLESPACE <tablespace_name> BUILD IMMEDIATE REFRESH <FAST | FORCE> ON <COMMIT | DEMAND> <USING INDEX | USING NO INDEX> INITRANS <integer> STORAGE CLAUSE AS (<SQL statement>);   CREATE MATERIALIZED VIEW [schema.]mview     Mview_Options     [USING INDEX storage_options]     [{REFRESH [refresh_options] |NEVER REFRESH]     [FORUPDATE] [{ENABLE|DISABLE} QUERY REWRITE]     AS subbquery; CREATE MATERIALIZED VIEW [schema.]mview     ON PREBUILT TABLE [{WITH |WITHOUT} REDUCED PRECISION]     [USING INDEX storage_options]     [{REFRESH [refresh_options]| NEVER REFRESH]     [FORUPDATE] [{ENABLE|DISABLE} QUERY REWRITE]     AS subbquery; --说明：上面的选项可安装自己的需要进行选择

                         interval => 'trunc(sysdate)+1+2/24');      commit;    end;      注意：创建后请不要再对物化视图进行刷新操作,由于odrd121_retapplyd_reports存储过程里已经对物化视图进行相关刷新操作，        如有需要可做相应的调整。    */
