一个简单的往数据库添加的问题
我要Windows身份认证，把已经验证的用户名添加到数据库中
可是在运行时总报错：INSERT INTO 语句的语法错误　我不知道怎么错的
帮忙看下
谢谢
protected void WindowsAuthentication_OnAuthenticate(object sender, WindowsAuthenticationEventArgs e)
{

OleDbConnection cnn = new OleDbConnection( "PROVIDER=Microsoft.Jet.OLEDB.4.0;DATA Source=E:\\example\\database.mdb ");
if(cnn.State == ConnectionState.Closed)
{
cnn.Open();
}

string str= "Insert Into regist (user_name,time) Values ( ' "+e.Identity .Name .ToString ()+ " ',GetDate()) ";
OleDbCommand cmd= new OleDbCommand (str);
cmd.Connection = cnn;

cmd.CommandType = CommandType.Text;
cmd.ExecuteNonQuery();


}

[解决办法]
1。

string str= "Insert Into regist (user_name,time) Values ( ' "+e.Identity .Name .ToString ()+ " ',GetDate()) ";

》》》

string str= "Insert Into regist (user_name,[time]) Values ( ' "+e.Identity.Name
.ToString()+ " ',Date()) ";

string str= "Insert Into regist (user_name,[time]) Values ( ' "+e.Identity .Name .ToString ()+ " ',Now()) ";
