经过查找一番资料，发现服务器配置选项里有一项”Max Text Repl Size”(“最大文本复制大小”)，它的默认值为65536，可以通过修改这个值解决上面的问题。

通过SELECT * FROM sys.configurations WHERE NAME LIKE '%repl%'

查询得到max text repl size (B) 最大值为2147483647，可以结合实际情况设置小于等于这个数值的值。

例如：

EXEC sp_configure 'show advanced options', 1
go
sp_configure 'max text repl size', '6553600'
go
RECONFIGURE

            }
            byte[] postHeaderBytes = Encoding.UTF8.GetBytes(sb.ToString());
            byte[] boundaryBytes = Encoding.ASCII.GetBytes("\r\n--" + boundary + "\r\n");

            Stream requestStream = webrequest.GetRequestStream();
            requestStream.Write(postDate, 0, postDate.Length);
            foreach (var filestream1 in fileStream)
            {

                byte[] buffer = new Byte[checked((uint)Math.Min(4096, (int)filestream1.Length))];
                int bytesRead = 0;
                while ((bytesRead = filestream1.Read(buffer, 0, buffer.Length)) != 0)
                    requestStream.Write(buffer, 0, bytesRead);
                requestStream.Write(boundaryBytes, 0, boundaryBytes.Length);
            }
            webrequest.Timeout = 1000000;
            WebResponse responce = webrequest.GetResponse();
            Stream s = responce.GetResponseStream();
            StreamReader sr = new StreamReader(s);

获取值：

文本框，文本区域：$("#txt").attr("value")；
多选框checkbox：$("#checkbox_id").attr("value")；
单选组radio：   $("input[@type=radio][@checked]").val();
下拉框select： $('#sel').val();

控制表单元素：
文本框，文本区域：$("#txt").attr("value",'');//清空内容
                 $("#txt").attr("value",'11');//填充内容

多选框checkbox： $("#chk1").attr("checked",'');//不打勾
                 $("#chk2").attr("checked",true);//打勾
                 if($("#chk1").attr('checked')==undefined) //判断是否已经打勾

单选组radio：    $("input[@type=radio]").attr("checked",'2');//设置value=2的项目为当前选中项
下拉框select：   $("#sel").attr("value",'-sel3');//设置value=-sel3的项目为当前选中项
                $("<option value='1'>1111</option><option value='2'>2222</option>").appendTo("#sel")//添加下拉框的option
                $("#sel").empty()；//清空下拉框

Example code

Converting a database or object creation queries to use memcached is simple. Typically, when using straight database queries, example code would be as follows:

function get_foo (int userid) {
result = db_select("SELECT * FROM users WHERE userid = ?", userid);
return result;
}

After conversion to memcached, the same call might look like the following

function get_foo (int userid) {
result = memcached_fetch("userrow:" + userid);
if (!result) {
result = db_select("SELECT * FROM users WHERE userid = ?", userid);
memcached_add("userrow:" + userid,  result);
}
return result;
}

The server would first check whether a memcached value with the unique key "userrow:userid" exists, where userid is some number. If the result does not exist, it would select from the database as usual, and set the unique key using the memcached API add function call.

However, if only this API call were modified, the server would end up fetching incorrect data following any database update actions: the memcached "view" of the data would become out of date. Therefore, in addition to creating an "add" call, an update call would be also needed, using the memcached set function.

function update_foo(int userid, string dbUpdateString) {
result = db_execute(dbUpdateString);
if (result) {
data = createUserDataFromDBString(dbUpdateString);
memcached_set("userrow:" + userid, data);
}
}

下午开始做 数据库,并测试通讯...

下午数据库已经建好,在和数据库通讯的时候出现了问题.

解决办法:
   1  UI层使用SEND方法将数据传递给.CS文件
例子:
<s:event b:on="click" b:action="send" b:url="ClassList.aspx" b:source="id('af')" />
form如下  ,ClassList是通讯页面,设计视图只有一个黄条的字背后的.CS文件才是实现数据库通讯,并返回
一个值.
<div id="testMM"></div>
 <form id="af" action="ClassList.aspx" method="post" b:destination="id('testMM')">

注意事项: 返回的所有值都必须符合XML规范.
