1. 拼删除语句：

select 'delete from '||table_name||' where ID_>10' from sysibm.tables where TABLE_schema='ODSUSER '

2.拼import语句：

select 'db2 IMPORT FROM '|| a.TABLE_NAME ||'.IXF OF IXF MODIFIED BY FORCECREATE COMMITCOUNT 10000

replace_create INTO ' ||a.TABLE_NAME

from sysibm.TABLES a where a.TABLE_SCHEMA='ODSUSER'

3. db2 删除前多少行
