为什么not logged initially
数据移动期间的选项比使用LOAD
DB2 中的实用程序更快?
最初未记录方法:
db2 alter table tablename activate not logged initially
db2 insert into table tablename select * from tbname
加载实用程序:
db2 declare source cursor for select * from tablename
db2 load from source of cursor insert into tablename nonrecoverable
