如何在Oracle中复制表l构和表数据
1. 复制表结构及(qing)其数据：(x)
create table table_name_new as select * from table_name_old
2. 只复制表l构Q?/p>
create table table_name_new as select * from table_name_old where 1=2;

在测试时两次发现

java.lang.IllegalArgumentException: argument type mismatch异常?br />
W一ơ，是由于在Form中定义的是String[] somethingID数组cdQ而在jsp中定义的?br /> <html:hidden property="somethingID"/>,Dcd不匹配，从而出现异常?br />
W二ơ出玎ͼ原因比较隐蔽。容我慢慢道来?br /> 两个画面QSomeList.jsp 和Some.jspQ分别对应SomeListFormQSomeListAction.java ?SomeFormQSomeChangeAction.java。功能就是打开SomeList.jsp画面Q选择某条Someq入SomeChange.jspQ修改好后返回SomeList.jsp。ؓ(f)了修正Session问题Q在Some.jsp中添加了<html:hidden property="somethingID"/>Q然后上面异常就发生了?br /> 历经挫折Q跋山涉水后扑ֈ原因。在SomeListForm中有属性String[] somethingIDQ数l类型，在SomeForm中有属性String somethingID是单值StringcdQ名字一致类型不一栗?br /> 当SomeChangeFormq回SomeListForm的时候，?x)将somethingID的g回。这时候就发生cd不匹配异怺。根本原因在于，配置struts-config.xml的时候，
<action attribute="someForm" input="/form/somechange.jsp" name="someForm"
path="/somechange" type="com.somecorp.struts.action.SomeChangeAction">
<forward name="display" path="/form/somechange.jsp" />
<forward name="return" path="/somelist.do" />
</action>
高亮q行没有讄 redirect="true"Q这L(fng)话，q回时就?x)将上个Form的D回从而导致不匚w异常?
path="/somechange" type="com.somecorp.struts.action.SomeChangeAction">
<forward name="display" path="/form/somechange.jsp" />
<forward name="return" path="/somelist.do" />
</action>
- 一般来_(d)q时候的Form是不需要将D回的Q改?span style="color: #000000;"><forward name="return" path="/somelist.do" redirect="true"/>可以了?span style="color: red;">要注意其他参数的传递?/span>
- q有个改法就是将两个Form中同名不同类型的属性改个名字也可以?/span>
==========打酱油的分割U?===================
对于redirect="true"不理解的可以参考下面这D：(x)
在ActionForward中有一个重要的属性redirectQ当redirect=falseӞ保存存储在httph和请求上下文中的所有内容，仅在同一个应用中可用。当redirect=trueӞW(xu)eb客户端进行一ơ新的httphQ请求的资源可以在同一个应用中Q也可以不在Q原来的h参数不再保存Q原来的h上下文也被清除，新的httph仅包含ActionForward的path属性里所包含的参数。如果在同一个应用中Q用户会(x)话的上下文会(x)被维护?/span>

struts-config.xml中action元素的attribute属性的意义
我觉得attributeq是有用的?
1Q应用前提，attribute只有在设|了name后才有意义?
2Qattribute可以实现对象的重用，卛_果设|了attribute属性，在创建actionform是，?x)先L扄应的scope中是否有此对象，如果有，则重用，否则创徏新的对象?
3Q当你将创徏的acitonForm保存到相应的scope中时Q你想用一个更有意义的名字来访问它Ӟ它就有意义了。例如：(x)
配置form.
<form-bean name="employee" type="Employee"/>
配置a(chn)ction:
<action
attribute="validEmployee"
name="employee"
type="EmployeeAction"
scope="request"
path="/employee">
.....
q样可以用validEmployee在JSP面中访问了Q而不是用employee.
q在同一个form 在不同情况下有不同的意义Ӟ意义才很明显?/font>
