使用物化视图解决GoldenGate不能使用中文表名问题

Posted 2020-10-07 长城之上是千亿的星空，星空之上是不灭的守望。

源端：

conn sh/sh

create table "学生" ("学号" number primary key,"姓名" varchar2(30))

                                               *

ORA-00957: duplicate column name 重复列名

create table "学生" ("学号" number primary key, " 姓名" varchar2(30));

 

create materialized view log on "学生" with primary key;

 

create materialized view mv_student

refresh fast on commit

as

select "学生"."学号" as id, "学生"." 姓名" as name from "学生";

 

添加这个物化视图的附加日志

GGSCI (linux5.5) 1> dblogin userid goldengate, password goldengate

info trandata sh.mv_student

add trandata sh.mv_student

 

SQL> select * from tab;

 

TNAME                          TABTYPE  CLUSTERID

------------------------------ ------- ----------

TEST                           TABLE

TEST1                          TABLE

TEST4                          TABLE

????                           TABLE

MLOG$_????                     TABLE

RUPD$_????                     TABLE

MV_STUDENT                     TABLE

一个一个指定，不能用模糊匹配，否则物化视图的日志、中文表，物化视图也会复制过去

GGSCI (linux5.5) 3> edit params ext_sh 

TABLE SH.test1;

TABLE SH.test4;

TABLE SH.mv_student;

GGSCI (linux5.5) 5> stop ext_sh

GGSCI (linux5.5) 7> start ext_sh

SQL> desc sh."学生"

 Name                                      Null?    Type

 ----------------------------------------- -------- ----------------------------

 ????                                      NOT NULL NUMBER

  ????                                              VARCHAR2(30)

 

如果用模糊匹配：

SQL> select * from tab;

 

TNAME                          TABTYPE  CLUSTERID

------------------------------ ------- ----------

TEST1                          TABLE

TEST4                          TABLE

????                           TABLE

BIN$6TRNVHJWkIHgQKjAqQoNFg==$0 TABLE

MLOG$_????                     TABLE

RUPD$_????                     TABLE

SQL> desc sh."学生"

ORA-00942: table or view does not exist
