t_role（主表），t_module_access（附表）一对多的关系
现在只想修改t_role表数据，可是hibernate会自动删除t_module_access的数据，
Hibernate:
update
T_ROLE
set
ROLE_NAME=?,
ORDER_NUM=?,
MEMO=?,
CREATE_DATE=?,
FLAG=?
where
SN=?
Hibernate:
delete
from
T_MODULE_ACCESS
where
ROLE_SN=?
Hibernate:
delete
from
T_GROUP_ROLE
where
ROLE_SN=?
[code="java"]
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
seq_T_ROLE
[/code]
不想要他执行下面的删除语句
