Using MySQL with .Net

April 25, 2012 Leave a comment

Required Components:

  • MySQL 5.0 database server
  • MySQL Connector/Net 1.0.6 or higher
  • MySQL Administrator 1.1 or higher
  • .NET Framework 1.0 or higher
  • Visual Studio 2002 or higher

Download and install MySQL Community Server
MySQL Community Edition is a freely downloadable version of the world’s most popular open source database that is supported by an active community of open source developers and enthusiasts.

Download Connector/Net
Connector/Net is a fully-managed ADO.NET driver for MySQL.

  • Download link : Connector/Net
  • Unzip the ZIP file to get the .MSI file and install it by double clicking on it.

Connect to MYSQL from .NET

  • Go to the solution explorer in Visual Studio and select Add References option.
  • From Add References dialog box, select “MySQL.Data” option and click on Ok.
  • Refer the following code to connect to MYSQL.
// Connection string for a typical local MySQL installation
string cnnString = 

// Create a connection object and data adapter
MySqlConnection cnx = new MySqlConnection(cnnString);
MySqlDataAdapter adapter = new MySqlDataAdapter();

// Create a SQL command object
string cmdText = "SELECT * FROM verse";
MySqlCommand cmd = new MySqlCommand(cmdText, cnx);

// Create a fill a Dataset
DataSet ds = new DataSet();
adapter.SelectCommand = cmd;

// Bind the DataSet
// ... Place your databinding code here ...

If you’re already accustomed to data binding in .NET, 
you should immediately recognize the similarities.  
The only difference is you use the MySqlXxx classes 
instead of the OleDbXxx or SqlXxx classes.

Sample MySQL Configuration File and Parameter Details

February 6, 2011 Leave a comment

Here is a copy of a sample MySQL configuration file and details on few main parameters:

# Example mysql config file for small systems.
# This is for a system with little memory (<= 64M) where MySQL is only used
# from time to time and it's important that the mysqld deamon
# doesn't use much resources.
# You can copy this file to
# /etc/my.cnf to set global options,
# mysql-data-dir/my.cnf to set server-specific options (in this
# installation this directory is /usr/local/mysql/var) or
# ~/.my.cnf to set user-specific options.
# One can in this file use all long options that the program supports.
# If you want to know which options a program support, run the program
# with --help option.

# The following options will be passed to all MySQL clients
#password	= your_password
port		= 3306
socket		= /tmp/mysql.sock

# Here follows entries for some specific programs

# The MySQL server
port		= 3306
socket		= /tmp/mysql.sock
set-variable	= key_buffer=128K
set-variable	= max_allowed_packet=1M
set-variable	= thread_stack=64K
set-variable	= table_cache=4
set-variable	= sort_buffer=64K
set-variable	= net_buffer_length=2K
server-id	= 1
