- Have a working mono and mcs installed
- Have access to a Microsoft SQL Server database
or either download it:
- IMPORTANT: If using Microsoft SQL Server 2000, make sure
you are using at least Service Pack 3 for Microsoft SQL Server 2000. If using
MSDE 2000, make sure you have the special Service Pack 3 for MSDE 2000. You
can get it from here
- For those that only have MSDE installed. You can change the authentication mode
from Windows Only Authentication to SQL Server and Windows Authentications (also knows as Mixed-mode authentication)
via the registry
. It is
the LoginMode you need to change. By default,
MSDE is installed with Windows Only Authentication. If you want SqlClient to work with MSDE via SQL Server authentication, you will
need to change the setting. Otherwise, you wil have to use NT Authentication.
- If using MSDE, you might need to create a new user with password. Give
this user access to various databases in this MSDE instance. Also, for each
database, give this new user at least SELECT access to the various tables you want
to retrieve data from.
- If you have Enterprise Manager, you can easily change the authentication mode
for both MSDE and Microsoft SQL Server. To change the authentication mode in
Enterprise Mananger, select the instance, right-click on it, and select properites.
The SQL Server properties dialog for that instance will pop up. Choose the Security
tab. Change the Authentication from Windows Only to SQL Server and Windows. If
the instance of your database does not show up in Enterprise Manager, Register first
by selecting the Action menu and choosing New SQL Server Registration.
- Located at mcs/class/System.Data/Test is a test for System.Data.SqlClient
named SqlTest.cs and you could use this as a basis for your test.
- If you want to use Integrated Security (aka NT Authentication aka Trusted Connection aka Domain Login), you
will need to specify the Domain User ID and Password. This is because Mono is not integrated with Windows
nor SQL Server.
- Has a connection string format for SQL Server Authentication:
Server=hostname;
Database=databaseName;
User ID=sqlServerUserid;
Password=sqlServerPassword
- Has a connection string format for NT Authentication:
Server=hostname;
Database=databaseName;
User ID=windowsDomain\windowsUserid;
Password=windowsPassword;
Integrated Security=SSPI
- The Server part can be used three ways:
| Server Definition | Example |
| hostname | Server=MYHOST |
| hostname,port | Server=MYHOST,1433 |
| hostname\instance | Server=MYHOST\NETSDK |
- C# Example using SQL Server Authentication:
using System;
using System.Data;
using System.Data.SqlClient;
public class Test
{
public static void Main(string[] args)
{
string connectionString =
"Server=MyServer;" +
"Database=pubs;" +
"User ID=MySqlServerUserId;" +
"Password=MySqlServerPassword;";
IDbConnection dbcon;
dbcon = new SqlConnection(connectionString);
dbcon.Open();
IDbCommand dbcmd = dbcon.CreateCommand();
string sql =
"SELECT fname, lname " +
"FROM employee";
dbcmd.CommandText = sql;
IDataReader reader = dbcmd.ExecuteReader();
while(reader.Read()) {
string FirstName = (string) reader["fname"];
string LastName = (string) reader["lname"];
Console.WriteLine("Name: " +
FirstName + " " + LastName);
}
// clean up
reader.Close();
reader = null;
dbcmd.Dispose();
dbcmd = null;
dbcon.Close();
dbcon = null;
}
}
- C# Example using NT Authentication (Integrated Security)
using System;
using System.Data;
using System.Data.SqlClient;
public class Test
{
public static void Main(string[] args)
{
string connectionString =
"Server=MyServer;" +
"Database=pubs;" +
"User ID=MyWindowsDomain\\MyWindowsUserid;" +
"Password=MyWindowsPassword;" +
"Integrated Security=SSPI";
IDbConnection dbcon;
dbcon = new SqlConnection(connectionString);
dbcon.Open();
IDbCommand dbcmd = dbcon.CreateCommand();
string sql =
"SELECT fname, lname " +
"FROM employee";
dbcmd.CommandText = sql;
IDataReader reader = dbcmd.ExecuteReader();
while(reader.Read()) {
string FirstName = (string) reader["fname"];
string LastName = (string) reader["lname"];
Console.WriteLine("Name: " +
FirstName + " " + LastName);
}
// clean up
reader.Close();
reader = null;
dbcmd.Dispose();
dbcmd = null;
dbcon.Close();
dbcon = null;
}
}
