闲着没事做，突然看到了Ogg的Foarmsql参数，可以把抽取的数据打印成Sql文本

1.配置ogg抽取

GGSCI (enmotech) 1> ADD EXTRACT e_sql, tranlog, BEGIN now
EXTRACT added.
 
 
GGSCI (enmotech) 2> edit params e_sql
 
EXTRACT e_sql
setenv ( NLS_LANG = AMERICAN_AMERICA.ZHS16GBK )
userid goldengate , password AACAAAAAAAAAAAKAPATACEHBIGQGCFZCCDIGAEMCQFFBZHVC,ENCRYPTKEY DEFAULT
FORMATSQL ORACLE, NONAMES
EXTTRAIL ./dirdat/es
 
 
TABLE ogg1.ogg_test;
TABLE ogg1.test1;
 
 
ADD EXTTRAIL ./dirdat/es, EXTRACT E_SQL
 
 
GGSCI (enmotech) 4> START E_SQL
 
Sending START request TO MANAGER ...
EXTRACT E_SQL starting

2.插入数据测试
