MySQL

Introduction


MySQL is a fast, easy-to-use RDBMS used being used for many small and big businesses. MySQL is developed, marketed, and supported by MySQL AB, which is a Swedish company. MySQL is becoming so popular because of many good reasons.

• MySQL is released under an open-source license. So you have nothing to pay to use it.
• MySQL is a very powerful program in its own right. It handles a large subset of the functionality of the most expensive and powerful database packages.
• MySQL uses a standard form of the well-known SQL data language.
• MySQL works on many operating systems and with many languages including PHP, PERL, C, C++, JAVA etc.
• MySQL works very quickly and works well even with large data sets.
• MySQL is very friendly to PHP, the most appreciated language for web development.
• MySQL supports large databases, up to 50 million rows or more in a table. The default file size limit for a table is 4GB, but you can increase this (if your operating system can handle it) to a theoretical limit of 8 million terabytes (TB).
• MySQL is customizable. The open source GPL license allows programmers to modify the MySQL software to fit their own specific environments.

Connect to a MySQL 5.0 database with ADO.NET
If you want to develop applications with the .NET Framework having a MySQL database as a data source you may want to try the MySQL Connector/NET 5.2. The MySQL Connector/NET is a fully managed ADO.NET component which provides specific implementation for all ADO.NET classes. You can download the MySQL Connector/NET 5.2 component from the MySQL web site. 


MySQL Connector/NET 5.2 main features

•     A new profile provider has been implemented along with a fully revamped provider schema.
•     New bulk loading and script execution classes are available.
•     The ability to clear a single or all connection pools.
•     Integration into Visual Studio 2008
•     MySqlDataAdapter now supports batching
•     BINARY(16) columns are now treated as GUIDs
•     Various changes in how we handle parameters.

How to use the MySQL Connector/NET
In order to use this component you have to add a reference to the MySql.Data.dll (from the MySQL Connector/NET package you downloaded form MySQL web site).

C# .NET

using MySql.Data.MySqlClient;

...

string connString = "SERVER=localhost;" +

                            "DATABASE=mySQLDatabase;" +

                            "UID=user;" +

                            "PASSWORD=password;";

MySqlConnection conn = new MySqlConnection(connString);

MySqlCommand command = conn.CreateCommand();

MySqlDataReader reader;

command.CommandText = "select * from table";

conn.Open();

reader = command.ExecuteReader();

while (reader.Read())

{

    // Read the value...

    string value = reader.GetValue(0).ToString();

}

conn.Close();
