  1. 故障分析及解决过程

有网友问，物化视图是否能单独进行导出和导入呢？因为导出不报错，但是导入的时候报错了，报错信息如下所示：

技术分享图片

网友给出的导出和导入的SQL语句如下所示：

expdp system/oracle dumpfile=dumpdir:mview.dmp schemas=scott include=materialized_view

impdp system/oracle dumpfile=dumpdir:mview.dmp

?

导出和导入语句没毛病，小麦苗自己也测试了一下，的确如此，会报错的。

非常奇怪。但是，基于SCHEMA模式导出和导入没有问题，那么可以尝试一下，然后查看其DDL语句，估计能找到一些蛛丝马迹：

果然找到一点蛛丝马迹，在创建物化视图之前，竟然创建了一张和物化视图同名的表。于是乎，测试一下：

?

?

create materialized VIEW mv_lhr as select * from lhr.tb_tmp;

SELECT * FROM dba_tables d WHERE d.TABLE_NAME LIKE ‘%MV_LHR%‘ ;

SELECT * FROM Dba_Mviews;

果然如此。

?

由此可知，在使用数据泵导出和导入物化视图时，以下SQL并不能创建和原物化视图一样的表，因此执行时会报错：

CREATE MATERIALIZED VIEW "LHR"."TEST_MV_LHR" ("OBJECT_ID", "OBJECT_NAME") USING ("TEST_MV_LHR", (10, ‘OCPLHR1‘, 1, 0, 0, "LHR", "TEST_MV", ‘2018-05-30 10:58:06‘, 0, 76926, ‘1950-01-01 12:00:00‘, ‘‘, 0, 1372748, 0, NULL, (1, "OBJECT_ID", "OBJECT_ID", 0, 321, 0)), 2097249, 10, (‘1950-01-01 12:00:00‘, 46, 0, 0, 1372748, 0, 0, 0, 1, NULL, NULL)) REFRESH FORCE WITH PRIMARY KEY AS SELECT "TEST_MV"."OBJECT_ID" "OBJECT_ID","TEST_MV"."OBJECT_NAME" "OBJECT_NAME" FROM "TEST_MV" "TEST_MV";

所以解决办法就很简单了，在导出的时候，需要导出和原物化视图同名的表即可。

可以看到，导入不报错了，但是，物化视图并没有数据。所以，还需要将物化视图的基本加上，这样才能将数据导出：

expdp system/lhr dumpfile=mview5.dmp schemas=lhr include=TABLE:\\"IN \\(\\‘TEST_MV_LHR\\‘,\\‘TEST_MV\\‘\\)\\",materialized_view:\\"IN \\(\\‘TEST_MV_LHR\\‘\\)\\"

?

最后查询MOS，在MOS中搜到一篇文章，如下：

Impdp of Materialized View Results in ORA-39083 and ORA-942 (文档 ID 549843.1)

其解决方案和我的一致。

?

?

最后，再说一个内容，如果命令中的转义字符看不懂（其实：单引号、双引号、小括号 都需要进行转义），或不会写，那么可以使用parfile参数来修改：

[[email protected] ~]$ cat par_lhr.par

include=TABLE:"IN (‘TEST_MV_LHR‘,‘TEST_MV‘)",materialized_view:"IN (‘TEST_MV_LHR‘)"

[[email protected] ~]$ expdp system/lhr dumpfile=mview6.dmp schemas=lhr parfile=par_lhr.par

  1. 故障处理总结

  1. 使用数据泵进行导出和导入时，基于schema和数据库级别可以导出和导入物化视图。
  2. 使用数据泵单独导出和导入物化视图（include=materialized_view）时，会报ORA-39083和ORA-00942错误。
  3. 在新建一个物化视图时，会同步新建一个同名的表。所以，使用数据泵单独导出和导入物化视图（include=materialized_view）时，需要加上这些同名的表。
  4. INCLUDE进行导出和导入时只会导出和导入显式指定的数据库对象，而其依赖的对象并不会进行导出和导入。
  5. 若只导出物化视图的创建语句，则可以使用如下SQL：

    expdp system/lhr dumpfile=mview4.dmp schemas=lhr include=TABLE:\\"IN \\(\\‘TEST_MV_LHR\\‘\\)\\",materialized_view:\\"IN \\(\\‘TEST_MV_LHR\\‘\\)\\"

    impdp system/lhr dumpfile=mview4.dmp

    若需要同步导出物化视图的创建语句及其存储的数据，则可以使用如下SQL：

    expdp system/lhr dumpfile=mview5.dmp schemas=lhr include=TABLE:\\"IN \\(\\‘TEST_MV_LHR\\‘,\\‘TEST_MV\\‘\\)\\",materialized_view:\\"IN \\(\\‘TEST_MV_LHR\\‘\\)\\"

    impdp system/lhr dumpfile=mview4.dmp

    exec dbms_mview.refresh(‘TEST_MV_LHR‘,‘C‘);

  6. 同步数据可以使用如下的SQL语句：

    exec dbms_mview.refresh(‘TEST_MV_LHR‘,‘C‘);

    ?

    ?

    1. 用到的SQL集合

    create table test_mv as select object_id,object_name from all_objects;

    alter table test_mv modify(object_id primary key);

    create materialized view log on test_mv ;

    create materialized view test_mv_lhr as select * from test_mv;

    TEST_MV是基表 TEST_MV_LHR是物化视图

    ?

    --不同步数据

    expdp system/lhr dumpfile=mview4.dmp schemas=lhr include=TABLE:\\"IN \\(\\‘TEST_MV_LHR\\‘\\)\\",materialized_view:\\"IN \\(\\‘TEST_MV_LHR\\‘\\)\\"

    impdp system/lhr dumpfile=mview4.dmp

    ?

    ?

    --TEST_MV是基表 同步数据

    expdp system/lhr dumpfile=mview5.dmp schemas=lhr include=TABLE:\\"IN \\(\\‘TEST_MV_LHR\\‘,\\‘TEST_MV\\‘\\)\\",materialized_view:\\"IN \\(\\‘TEST_MV_LHR\\‘\\)\\"

    impdp system/lhr dumpfile=mview4.dmp

    exec dbms_mview.refresh(‘TEST_MV_LHR‘,‘C‘);

    ?

    ?

    parfile的使用：

    [[email protected] ~]$ cat par_lhr.par

    include=TABLE:"IN (‘TEST_MV_LHR‘,‘TEST_MV‘)",materialized_view:"IN (‘TEST_MV_LHR‘)"

    [[email protected] ~]$ expdp system/lhr dumpfile=mview6.dmp schemas=lhr parfile=par_lhr.par
