[求助]数据写入无效?
在用AJAX实现一个聊天室~但是在提交文本框输入的内容后，却没写入相应的表里~
存储过程:
CREATE PROCEDURE [dbo].[SendNewMsg]--获取输入的信息
(
@content varchar(300),
@user_to varchar(50),
@username varchar(50),
@face varchar(50),
@color varchar(50)
)
AS
insert into [Chat_Info] (content,user_from,user_to,face,color,composetime) values (@content,@username,@user_to,@face,@color,Getdate())
GO

WEB.CONFIG里添加
<httpHandlers>
<add verb= "POST,GET " path= "ajax/*.ashx " type= "Ajax.PageHandlerFactory, Ajax " />
</httpHandlers>
[解决办法]
sqlconn.Parameters.Add( "@user_to ",user_to);
改成：
m_command.Parameters.Add( "@user_to ",SqlDbType.NVarChar,40).Value=user_to
[解决办法]
CREATE PROCEDURE [dbo].[SendNewMsg]--获取输入的信息
AS
insert into [Chat_Info] values (@content,@username,@user_to,@face,@color,Getdate())
GO
这样如何
[解决办法]
打断点啊 一句句找 看看 insert 那边执行的怎么样
