- <li>TODO
</ul>
+
+** Testing
+
+<ul>
+ <li>Have a working mono and mcs installed</li>
+
+ <li>Have access to a Microsoft SQL Server database
+ or either download it:
+ <ul>
+ <li><a href="http://www.microsoft.com/sql/default.asp">Microsoft SQL Server</a></li>
+ </ul>
+ </li>
+
+ <li>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.</li>
+
+ <li>For those that only have MSDE installed. You can change the authentication mode \r
+ from Windows Only Authentication to SQL Server and Windows Authentications (also knows as Mixed-mode authentication)\r
+ via the <a href="http://support.microsoft.com/default.aspx?scid=kb;en-us;Q322336&sd=tech#4">registry</a></li>. It is\r
+ the LoginMode you need to change. By default,\r
+ MSDE is installed with Windows Only Authentication. For SqlClient to work with MSDE, you will\r
+ need to change the setting.</a>\r
+ \r
+ <li>If using MSDE, you might need to create a new user with password. Give\r
+ this user access to various databases in this MSDE instance. Also, for each\r
+ database, give this new user at least SELECT access to the various tables you want\r
+ to retrieve data from.</li>\r
+ \r
+ <li>If you have Enterprise Manager, you can easily change the authentication mode\r
+ for both MSDE and Microsoft SQL Server. To change the authentication mode in \r
+ Enterprise Mananger, select the instance, right-click on it, and select properites.\r
+ The SQL Server properties dialog for that instance will pop up. Choose the Security\r
+ tab. Change the authentication from Windows Only to SQL Server and Windows. If\r
+ the instance of your database does not show up in Enterprise Manager, Register first\r
+ by selecting the Action menu and choosing New SQL Server Registration.</li>\r
+
+ <li>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.</li>
+
+ <li>Mono's SqlClient does not support trusted connections
+ nor integrated security. You can not use this when connecting. You need
+ to explicitly use a User ID and Password
+ authenticated by SQL Server.</li>
+
+ <li>Has a connection string format:
+<pre>
+ Server=hostname;Database=databaseName;User ID=userid;Password=password
+</pre>
+ </li>
+ <li>The Server part can be used three ways:
+
+ <table border=1>
+ <tr>
+ <td><b>Server Definition</b></td> <td><b>Example</b></td>
+ </tr>
+
+ <tr>
+ <td>hostname</td> <td>Server=MYHOST</td>
+ </tr>
+
+ <tr>
+ <td>hostname,port</td> <td>Server=MYHOST,1433</td>
+ </tr>
+
+ <tr>
+ <td>hostname\\instance</td> <td>Server=MYHOST\\NETSDK</td>
+ </tr>
+ </table>
+ </li>
+
+ <li>C# Example:
+<pre>
+ using System;
+ using System.Data;
+ using System.Data.SqlClient;
+
+ public class Test
+ {
+ public static void Main(string[] args)
+ {
+ string connectionString =
+ "Server=localhost;" +
+ "Database=pubs;" +
+ "User ID=myuserid;" +
+ "Password=mypassword;";
+ 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;
+ }
+ }
+</pre>
+ </li>
+ <li>Building C# Example:
+ <ul>
+ <li>Save the example to a file, such as, TestExample.cs</li>
+ <li>Build on Linux:
+<pre>
+ mcs TestExample.cs -r System.Data.dll
+</pre>
+ </li>
+ <li>Build on Windows via Cygwin:
+<pre>
+ mono C:/cygwin/home/MyHome/mono/install/bin/mcs.exe \
+ TestExample.cs -r System.Data.dll
+</pre>
+ </li>
+ </ul>
+ </li>
+ <li>Running the Example:
+<pre>
+mono TestExample.exe
+</pre>
+ </li>
