使用defgen 实现表结构不一致数据同步：
源端 和目标端 表结构不一样，用下面的方法实现：
源端
create table test_pri(id number primary key, name varchar2(10));
目标端：
create table test_pri(id number primary key);
源端 ggsci中
edit params defgen
defsfile /ogg/test_pri.p
userid ogg,password ogg
table song.test_pri; --第一次这里没有加分号，报错
[oracle@localhost ogg]$ defgen paramfile /ogg/dirprm/defgen.prm
