比如有个如下的中文表:
示例40:
create table 测试表(
ID NUMBER,
姓名 VARCHAR2(30),
FLAG CHAR(1),
CONSTRAINT PK_TESTD PRIMARY KEY (ID) USING INDEX);
--源端创建MV LOG和MV:
drop materialized view log on "测试表";
create materialized view log on "测试表" with primary key;
drop materialized view mv_cn_table;
create materialized view mv_cn_table refresh fast on commit as select id,姓名 as en_name,flag from "测试表";
在目标端创建表及view:
示例41:
create or replace view v_cn_table as select id,姓名 as en_name,flag from 测试表;
这里NLS_LANG在GG中,抽取和复制必须设置为和目标字符集一致:
示例42:
SETENV (NLS_LANG = "AMERICAN_AMERICA.AL32UTF8")
Extract相关:
示例43:
extract ODISC
SETENV (NLS_LANG = "AMERICAN_AMERICA.AL32UTF8")
userid custom_src, password custom_src
exttrail D:/GoldenGate/dirdat/ODISoc/oc
TABLE CUSTOM_SRC.MV_CN_TABLE;
Pump相关:
示例44:
extract ODIT1P
SETENV (NLS_LANG = "AMERICAN_AMERICA.AL32UTF8")
PASSTHRU
rmthost localhost, mgrport 7909
rmttrail D:/gg_stg/dirdat/ODIT1op/op
TABLE CUSTOM_SRC.MV_CN_TABLE;
Replicat相关:
示例45:
replicat ODIT1A1
SETENV (NLS_LANG = "AMERICAN_AMERICA.AL32UTF8")
userid odi_staging, password odi_staging
discardfile D:/gg_stg/dirrpt/ODIT1.dsc, purge
ASSUMETARGETDEFS
这里必须指定APPLYNOOPUPDATES参数,否则UPDATE有问题,另外,也要指定KEYCOLS,否则删除和更新有问题:
示例46:
map CUSTOM_SRC.MV_CN_TABLE, TARGET ODI_STAGING.V_CN_TABLE, KEYCOLS (ID);
