发生异常。关键字 'Table' 附近的语法不正确

Question

public partial class Login : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {

    }

    protected void Button1_Click(object sender, EventArgs e)
    {
        string connect_str = @"Data Source=(LocalDB)\MSSQLLocalDB;AttachDbFilename=C:\Users\Chamod\Documents\Chamod.mdf;Integrated Security=True";
        SqlCommand cmd = new SqlCommand();
        string ms_sql_str = "SELECT * FROM Table ";
        cmd.CommandText = ms_sql_str;
        SqlConnection connection = new SqlConnection(connect_str);
        cmd.Connection = connection;
        connection.Open();

        SqlDataReader dr = cmd.ExecuteReader();
        if(dr.HasRows)
        {
            Session["Admin"] = t1.Text.Trim();
            Response.Redirect("First.aspx");
        }
        else
        {
          //  spnmsg.Visible = true;
        }
        connection.Close();

    }
}

我正在为酒店创建登录系统。当我要登录系统时， VS 2015 指向 SqlDataReader dr = cmd.ExecuteReader(); 行。意思是

"An unhandled exception occurred during the execution of the current web request."

我有很多错误，我不知道如何完成代码。请给我一个解决方案。

Answer 1

TABLE 是一个 reserved 关键字，因此您应该更改它的名称，或者您应该将它括在方括号中，例如 [Table]:

string ms_sql_str = "SELECT * FROM [Table] ";

但是在 MySQL 中我认为你应该使用反引号 (``):

string ms_sql_str = "SELECT * FROM `Table` ";

发生异常。关键字 'Table' 附近的语法不正确

An exception occurred .. Incorrect syntax near the keyword 'Table'
