我有一个关于ASP.NET和SQL Server数据库和使用Visual Studio 2010的问题。问题是关于登录控件cs部分。登录控制asp.net和CS
我联系我与数据库的形式,需要比较与那些在DB登录名和密码,但行
SqlDataReader rdr = com.ExecuteReader();
说有语法附近“用户”
它是一个错误查询问题?
你能帮助我吗?
private bool UserLogin(string userName, string password)
{
// read the coonection string from web.config
string conString = ConfigurationManager.ConnectionStrings["MidLinData"].ConnectionString;
using (System.Data.SqlClient.SqlConnection con = new System.Data.SqlClient.SqlConnection(conString))
{
con.Open();
//' declare the command that will be used to execute the select statement
// SqlCommand com = new SqlCommand("SELECT login FROM user WHERE userName = @login AND Password = @password", con);
SqlCommand com = new SqlCommand("SELECT login FROM user WHERE userName = @login ", con);
SqlCommand com2 = new SqlCommand("SELECT password FROM user WHERE password = @password ", con);
// set the username and password parameters
com.Parameters.Add("@login", SqlDbType.NVarChar).Value = userName;
SqlDataReader rdr = com.ExecuteReader();
//com.Parameters.Add("@password", SqlDbType.NVarChar).Value = password;
string result = rdr[0].ToString();
// execute the select statment
// string result = Convert.ToString(com.ExecuteScalar());
//' check the result
if (string.IsNullOrEmpty(result))
{
//invalid user/password , return flase
return false;
}
else
{
// valid login
return true;
}
return true;
}
}
编译器说:

Incorrect syntax near the keyword 'user'.

张贴从编译器错误信息可能会有帮助。 – vdbuilder
