* MySQL Data Provider
+ <p>There are two ADO.NET providers in Mono
+ for a <a href="http://www.mysql.com/">MySQL</a> database:
+
<ul>
- <li>MySQL Data Provider for
- <a href="http://www.mysql.com/">MySQL</a> databases. It is written in C# and uses
- the MySQL C Client Library
+ <li><a href="http://sourceforge.net/projects/mysqlnet/">ByteFX.Data.MySQLClient</a>
+ <ul>
+ <li>Written in 100% C#</li>
+ <li>Does not require a client library</li>
+ <li>Works on Mono and Microsoft .NET</li>
+ <li>Requires at least Mono 0.18 and MySQLNet 0.65 for it to work on Mono</li>
+ <li>Works in the SQL# command-line and GTK# GUI version</li>
+ </ul>
+ </li>
- <li>Exists in namespace Mono.Data.MySql and assembly Mono.Data.MySql
-
- <li>Works on Windows and Linux via the MySQL client shared library
- (libmySQL.dll on Windows and libmysqlclient.so on Linux).
-
- <li>Started by Daniel Morgan using C# Bindings to MySQL from Brad Meril.
-
- <li><a href="http://www.mysql.com/articles/dotnet/">Exploring MySQL in the Microsoft .NET Environment</a> is an article
- by Mr. Venu who is a MySQL AB developer.
-
- <li>Other projects which have created a .NET Data provider for MySQL in C#
+ <li>Mono.Data.MySql (deprecated)
<ul>
- <li><a href="http://sourceforge.net/projects/mysqldrivercs/">MySQLDriverCS</a> is a MySQL provider written in C#
- <li><a href="http://sourceforge.net/projects/mysqlnet/">MySQLNet</a> is a MySQL Manager provider written in C#
+ <li>Deprecated in favor of ByteFX.Data.MySQLClient

+ <li>Exists in namespace Mono.Data.MySql and assembly Mono.Data.MySql</li>

</ul>
+ </li>
+
+ <li>Bugs with Mono or the data provider should be reported
+ in Mono's Bugzilla <a href="http://bugzilla.ximian.com/">here</a>. If you
+ do not have Bugzilla user account, it is free
+ and easy to
+ create one <a href="http://bugzilla.ximian.com/createaccount.cgi">here</a>.</li>

-* Action plan

+ The current plan for the MySQL data providers:
+
+ <ul>
+ <li>ByteFX.Data.MySQLClient
+ <ul>
+ <li>Testing and fixes</li>
+ <li>Implement missing features</li>
+ <li>Only fixes for bugs to build and run MySQLClient on Mono
+ will be accepted in mono-cvs. Most bugs and any new features will
+ go into sourceforge cvs. Anytime there is a release of MySQLClient,
+ the source code will be copied from sourceforge cvs to mono-cvs</li>
+ <li>Releases of MySQLClient are determined by Reggie Burnett and releases
+ of Mono are determined by Miguel de Icaza</li>
+ <li>Implement any missing features or fix any bugs in Mono to get new
+ features all of MySQLClient to work on Mono</li>
+ </ul>
+ </li>
+ <li>Mono.Data.MySql (deprecated)
+ <ul>
+ <li>Testing and bug fixes</li>
+ <li>Mono.Data.MySql is deprecated and therefore maybe removed
+ at a later date. It will stay in Mono for now because other
+ programs maybe using it now.</li>
+ </ul>
+ </li>
+</ul>
+
+** Testing for MySQLNet provider (ByteFX.Data.MySQLClient)
+
+<ul>
+ <li>Have access to a MySQL database or download it from
+ <ul>
+ <li><a href="http://www.mysql.com/downloads/index.html">MySQL AB</a></li>
+ </ul>
+ </li>
+ <li>MySQLNet can be gotten from <a href="http://sourceforge.net/projects/mysqlnet/">here</a> and the
+ binary assembly ByteFX.Data.dll needs to be installed
+ in the same place as the mono class libraries.</li>
+
+ <li>MySQLNet requires <a href="http://www.icsharpcode.net/OpenSource/SharpZipLib/default.asp">SharpZipLib</a> which is
+ a Zip Library written in 100% C#. This is used for compression/decompression of data
+ sent/received over the network. The SharpZipLib binary assembly SharpZipLib.dll should
+ be installed in the same place as the mono class libraries.</li>
+
+ <li>Has a ConnectionString format:
+<pre>
+"Server=hostname;" +
+"Database=database;" +
+"User ID=username;" +
+"Password=password"
+</pre>
+ </li>
+ <li>C# Example:
+<pre>
+ using System;
+ using System.Data;
+ using ByteFX.Data.MySQLClient;
+
+ public class Test
+ {
+ public static void Main(string[] args)
+ {
+ string connectionString =
+ "Server=localhost;" +
+ "Database=test;" +
+ "User ID=myuserid;" +
+ "Password=mypassword;";
+ IDbConnection dbcon;
+ dbcon = new MySQLConnection(connectionString);
+ dbcon.Open();
+ IDbCommand dbcmd = dbcon.CreateCommand();
+ // requires a table to be created named employee
+ // with columns firstname and lastname
+ // such as,
+ // CREATE TABLE employee (
+ // firstname varchar(32),
+ // lastname varchar(32));
+ string sql =
+ "SELECT firstname, lastname " +
+ "FROM employee";
+ dbcmd.CommandText = sql;
+ IDataReader reader = dbcmd.ExecuteReader();
+ while(reader.Read()) {
+ string FirstName = (string) reader["firstname"];
+ string LastName = (string) reader["lastname"];
+ 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>Parameters support via MySqlParameter and MySqlParameterCollection
-
- <li>Support LOBs (Large Object)
-
- <li>Change the MySQL provider to not be dependent on a client library and
- be written in 100% C#
-
- <li>Connection pooling
-
- <li>Get the provider to work like other data providers
+ <li>Save the example to a file, such as, TestExample.cs</li>
+ <li>Build on Linux:
+<pre>
+ mcs TestExample.cs -r System.Data.dll \
+ -r ByteFX.Data.dll
+</pre>
+ </li>
+ <li>Build on Windows via Cygwin:
+<pre>
+ mono C:/cygwin/home/MyHome/mono/install/bin/mcs.exe \
+ TestExample.cs \
+ -lib:C:/cygwin/home/MyHome/mono/install/lib \
