提示insert into出错..不知道错在哪里, 帮忙看看

Question

代码如下
每次提示:INSERT INTO 语句的语法错误。 
说明: 执行当前 Web 请求期间，出现未处理的异常。请检查堆栈跟踪信息，以了解有关该错误以及代码中导致错误的出处的详细信息。 异常详细信息: System.Data.OleDb.OleDbException: INSERT INTO 语句的语法错误。                           ........
OleDbConnection myconn= new OleDbConnection(ConnString);
OleDbDataAdapter mycommand=new OleDbDataAdapter("Select user,email,password,hellacah from m_tacle where user='"+user.Text+"'", myconn);
DataSet ds=new DataSet();
mycommand.Fill(ds,"m_tacle");
DataTable table=ds.Tables["m_tacle"];
DataRow dr=ds.Tables["m_tacle"].NewRow();
dr[0]=username.Text.ToString();
dr[1]=password.Text.ToString();
dr[2]=email.Text.ToString();
table.Rows.Add(dr);
mycommand.InsertCommand=new OleDbCommand("insert into m_tacle(user,password,email) values('"+dr[0]+"','"+dr[1]+"'','"+dr[2]+"')",oleConn);
OleDbCommandBuilder objCommandBuilder  =new OleDbCommandBuilder(mycommand);
mycommand.Update(ds,"m_tacle");

Answer 1

mycommand.InsertCommand=new OleDbCommand("insert into m_tacle(user,password,email) values("+dr[0]+","+dr[1]+","+dr[2]+")",oleConn);
--引号用的有问题

Answer 2

values('"+dr[0]+"','"+dr[1]+"','"+dr[2]+"')",myconn);
修改成了这样还是不行还是提示INSERT INTO 语句的语法错误。

Answer 3

mycommand.InsertCommand=new OleDbCommand("insert into m_tacle(user,password,email) values('"+dr[0]+"','"+dr[1]+"','"+dr[2]+"')",oleConn);

Answer 4

OleDbConnection myconn= new OleDbConnection(ConnString);
OleDbDataAdapter mycommand=new OleDbDataAdapter("Select user,email,password,hellacah from m_tacle where user='"+user.Text+"'", myconn);
DataSet ds=new DataSet();
mycommand.Fill(ds,"m_tacle");
DataTable table=ds.Tables["m_tacle"];
DataRow dr=ds.Tables["m_tacle"].NewRow();dr.ItemArray[0]=username.Text.ToString();//modified
dr.ItemArray[1]=password.Text.ToString();//modified
dr.ItemArray[2]=email.Text.ToString();//modifiedtable.Rows.Add(dr);mycommand.InsertCommand=new OleDbCommand("insert into m_tacle(user,password,email) values('"+dr.ItemArray[0].ToString()+"','"+dr.ItemArray[1].ToString()+"','"+dr.ItemArray[2].ToString()+"')",oleConn);//modifiedOleDbCommandBuilder objCommandBuilder  =new OleDbCommandBuilder(mycommand);
mycommand.Update(ds,"m_tacle");

Answer 5

提示:
说明: 执行当前 Web 请求期间，出现未处理的异常。请检查堆栈跟踪信息，以了解有关该错误以及代码中导致错误的出处的详细信息。 异常详细信息: System.Data.OleDb.OleDbException: INSERT INTO 语句的语法错误。源错误: 
行 181：  mycommand.InsertCommand=new OleDbCommand("insert into m_tacle(user,password,email) values('"+dr[0]+"','"+dr[1]+"','"+dr[2]+"')",oleConn);
mycommand.InsertCommand=new OleDbCommand("insert into m_tacle(user,password,email) values("+dr[0]+","+dr[1]+","+dr[2]+")",oleConn);
这2个都试验了...
行 182：OleDbCommandBuilder objCommandBuilder  =new OleDbCommandBuilder(mycommand);
行 183： mycommand.Update(ds,"m_tacle");<--红色显示这里

用了你这个方法还是提示错误奇怪了...

Answer 7

设置断点调试，然后选中语句,按下Ctrl+alt+Q，查看生成好的语句，
然后复制到ORACLE查询分析器里，去掉前后的引号，执行语句就知道错误在什么地方了

Answer 8

不好意思，看错了，以为你用了Oracle数据库，抱歉
复制到SQL查询分析器中执行

Answer 9

使用了你的方法调试
用label1输出insert语句..
发现赋值不了
insert into m_tacle(user,password,email) values('','','')

Answer 10

insert into m_tacle([user],password,email) ...在user这个字段处加上中括号,原因你可以查一下sql的帮助,写得很清楚.
