* MySQL Data Provider
-<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>
+ <p>There are two ADO.NET providers in Mono
+ for a <a href="http://www.mysql.com/">MySQL</a> database:
- <li>Exists in namespace Mono.Data.MySql and assembly Mono.Data.MySql</li>
-
- <li>Works on Windows and Linux via the MySQL client shared library
- (libmySQL.dll on Windows and libmysqlclient.so on Linux).</li>
-
- <li>Started by Daniel Morgan using
- <a href="http://www.cybercom.net/~zbrad/DotNet/MySql/">C# Bindings to MySQL</a> from <a href="mailto:zbrad@cybercom.net">Brad Merill</a>
-
- <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>
-
- <li>There is a good alternative to the provider in Mono:
+<ul>
+ <li><a href="http://sourceforge.net/projects/mysqlnet/">ByteFX.Data.MySQLClient</a>
<ul>
- <li><a href="http://sourceforge.net/projects/mysqlnet/">MySQLNet</a> from ByteFX
- is a MySQL Managed provider written in 100% C#,
- does not require a client library, and works on Microsoft .NET and Mono. You
- need at least Mono 0.18 and MySQLNet 0.65 for it to work on Mono. MySQLNet
- works in the SQL# command-line and GTK# GUI version</li>

- </li>
- <li>Testing for Mono's Mono.Data.MySql and ByteFX's ByteFX.Data.MySQLClient is below...</li>
-</ul>
-
-** Current Status
+ </li>
-<ul>
- <li>can connect
-
- <li>can execute non-queries via ExecuteNonQuery()
-
- <li>can execute aggregates via ExecuteScalar() and retrieve the
- single row/single column result
-
- <li>can execute queries and retrieve results using a data reader.
-
- <li>a schema DataTable has been partially
- implemented which is returned from GetSchemaTable() in MySqlDataReader.
+ <li>Mono.Data.MySql (DEPRECATED)
+ <ul>
+ <li>Deprecated in favor of ByteFX.Data.MySQLClient. Mono.Data.MySql is no longer included in
+ Mono releases.</li>
+ </ul>
+ </li>
- <li>a DataTable in a DataSet can be filled via a MySqlDataAdapter
-
- <li>The shared client libraries
- between windows version and linux are different: windows has libmySQL.dll
- while linux has libmysqlclient.so. This is handled by the
- file etc/mono/config which is mapped by the mono runtime in knowing
- which native shared library to load. In cvs, this file is mono/config.in and
- can be modified with a text editor.
+ <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>
- <li>Works in the SQL# command-line and GTK# GUI version</li>
</ul>
-** Action plan
-
-The current plan to work on the MySQL data provider:
-
- <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
- </ul>
+ <p><a href="http://www.mysql.com/articles/dotnet/">Exploring MySQL
+ in the Microsoft .NET Environment</a> is a nice article to read.</li>
+
+** Current Status
-** Testing for Mono's MySQL provider (Mono.Data.MySql)
+ Current Status of the MySQL providers:
<ul>
- <li>Have access to a MySQL database or download it from
+
+ <li>ByteFX.Data.MySqlClient
<ul>
- <li><a href="http://www.mysql.com/downloads/index.html">MySQL AB</a></li>
+ <li>Build and Runs on Microsoft .NET and Mono</li>
+ <li>Works with SQL# (command-line and GTK# GUI versions)</li>\r
+ <li>MySQLCommandBuilder now implemented</li>\r
+ <li>Transaction support now implemented (not all table types support this)</li>\r
+ <li>GetSchemaTable fixed to not use xsd (for Mono)</li>\r
+ <li>Driver is now Mono-compatible</li>\r
+ <li>TIME data type now supported</li>\r
+ <li>More work to improve Timestamp data type handling</li>\r
+ <li>Changed signatures of all classes to match corresponding SqlClient classes</li>\r
+ <li>Protocol compression using <a href="http://www.icsharpcode.net/OpenSource/SharpZipLib/default.asp">SharpZipLib</a></li>\r
+ <li>Named pipes on Windows now working properly</li>\r
+ <li>Work done to improve Timestamp data type handling</li>\r
+ <li>Implemented IEnumerable on DataReader so DataGrid would work</li>\r
+ <li>Speed increased dramatically by removing bugging network sync code</li>\r
+ <li>Driver no longer buffers rows of data (more ADO.Net compliant)</li>\r
+ <li>Conversion bugs related to TIMESTAMP and DATETIME fields fixed</li>\r
+
</ul>

- <li>Take a look at MySqlTest.cs in mcs/class/Mono.Data.MySql/Test</li>
+ <li>Mono.Data.MySql (DEPRECATED)
+ </li>
- <li>Has a ConnectionString format:
-<pre>
- "Server=hostname;" +
- "Database=database;" +
- "User ID=username;" +
- "Password=password"
- (or)
- "host=hostname;" +
- "dbname=database;" +
- "user=username;" +
- "passwd=password"
-</pre>
+</ul>
- <li>C# Example:
-<pre>

+ 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>
