没有Windows身份验证的MS SQL ODBC连接

Question

I'm trying to connect to MS SQL using ODBC but keep getting the "Login failed for user 'User-PC\\User'" error.

web.config 
<add name="SQLDbConnection" connectionString="Server=127.0.0.1; Database=HMS; Integrated Security=false; User Id=sa; password=root" providerName="System.Data.Odbc "/>

C#
        string query = "...";
        OdbcConnection msSQLConnection = new OdbcConnection(strConnection);
        OdbcCommand command = new OdbcCommand(query, msSQLConnection);
        command.Connection.Open();

I tried using the below and it's ok. Any idea how I can get ODBC to work?

using (SqlConnection cn = new SqlConnection(ConfigurationManager.ConnectionStrings["SQLDbConnection"].ToString()))
        {
            SqlCommand cmd = new SqlCommand("SELECT COMPANY_ID from COMPANY", cn);
            cn.Open();
            SqlDataReader rdr = cmd.ExecuteReader(CommandBehavior.CloseConnection);
            rdr.Read();
        }

Answer 1

SQL Connection and ODBC Connection do not use the same connection strings. For the ODBC connection you need to specify the driver.

For SQL Server 2012:

Driver={SQL Server Native Client 11.0};Server=127.0.0.1;Database=HMS;Uid=sa;Pwd=root;

Answer 2

You should use something like this :

    DRIVER={MySQL ODBC 3.51 Driver}; SERVER=127.0.0.1; DATABASE=HMS; USER=sa; PASSWORD=root;

Then take a look in here : OBDC example and then in here : Connection strings
