What is MySQL

MySQL is one of the most popular relational database system being used on the Web today. It is freely available and easy to install, however if you have installed Wampserver it already there on your machine. MySQL database server offers several advantages:

  • MySQL is easy to use, yet extremely powerful, fast, secure, and scalable.
  • MySQL runs on a wide range of operating systems, including UNIX or Linux, Microsoft Windows, Apple Mac OS X, and others.
  • MySQL supports standard SQL (Structured Query Language).
  • MySQL is ideal database solution for both small and large applications.
  • MySQL is developed, and distributed by Oracle Corporation.
  • MySQL includes data security layers that protect sensitive data from intruders.
  1. MySQL is easy to use, yet extremely powerful, fast, secure, and scalable. MySQL runs on a wide range of operating systems, including UNIX or Linux, Microsoft Windows, Apple Mac OS X, and others. MySQL supports standard SQL (Structured Query Language). MySQL is ideal database solution for both small and large applications.
  2. The following is an example walkthrough of importing an Excel document into a MySQL database. To run this tutorial you will need an Excel file, and admin access to a running MySQL instance. For the example we’ll be using the following Excel file on rental boats: boats.xlsx.
  3. MySQL is especially popular on the web. It is one part of the very popular LAMP platform consisting of Linux, Apache, MySQL, and PHP. Currently MySQL is owned by Oracle. MySQL database is available on most important OS platforms. It runs on BSD Unix, Linux, Windows or Mac OS. MySQL comes in two versions: MySQL server system and MySQL embedded.

MySQL database stores data into tables like other relational database. A table is a collection of related data, and it is divided into rows and columns.

Each row in a table represents a data record that are inherently connected to each other such as information related to a particular person, whereas each column represents a specific field such as id, first_name, last_name, email, etc. The structure of a simple MySQL table that contains person's general information may look something like this:

Tip: Websites like Facebook, Twitter, Wikipedia uses MySQL for their storage need. So you can easily understand what MySQL is capable of.

Talking to MySQL Databases with SQL

SQL, the Structured Query Language, is a simple, standardized language for communicating with relational databases like MySQL. With SQL you can perform any database-related task, such as creating databases and tables, saving data in database tables, query a database for specific records, deleting and updating data in databases.

Look at the following standard SQL query that returns the email address of a person whose first name is equal to 'Peter' in the persons table:

SELECT email FROM persons WHERE first_name='Peter'

If you execute the SQL query above it will return the following record:

C# MySQL tutorial shows how to program MySQL in C#. It covers the basics ofMySQL programming with C#. The examples require C# 8.0+. C# tutorialis a comprehensive tutorial on C# language.

MySQL

MySQL is a leading open source database management system. It is a multi user, multithreaded database management system. MySQL is especially popular on the web. It is one part of the very popular LAMP platform consisting of Linux, Apache, MySQL, and PHP. Currently MySQL is owned by Oracle.MySQL database is available on most important OS platforms. It runs on BSD Unix, Linux, Windows or Mac OS. MySQL comes in two versions: MySQL server system and MySQLembedded system.

ADO.NET

ADO.NET is an important part of the .NET framework. It is a specificationthat unifies access to relational databases, XML files and other application data.MySql.Data is an implementation of the ADO.NET specificationfor the MySQL database. It is a driver written in C# language and is available forall .NET languages.

We include the package to our .NET Core project.

The MySqlConnection, MySqlCommand, MySqlDataReader, DataSet, and MySqlDataProvider are the core elementsof the .NET data provider model. The MySqlConnection creates a connection to a specific data source. The MySqlCommand object executes an SQL statementagainst a data source. The MySqlDataReader reads streams of data from a data source.

The DataSet object is used for offline work with a massof data. It is a disconnected data representation that can hold data from a variety of different sources. Both MySqlDataReader and DataSet are used to work with data; they are used under different circumstances. If we only need to read the results of a query, the MySqlDataReader is the better choice. If we need more extensive processing of data, or we want to bind a Winforms control to a database table, the DataSet is preferred.

C# MySQL version

If the following program we check the version of the MySQL server.

We connect to the database and get some info about the MySQL server.

We import the elements of the MySQL data provider.

This is the connection string. It is used by the data provider to establish aconnection to the database. We specify the host name, user name, password and adatabase name.

A MySQLConnection object is created. This object is used toopen a connection to a database. The using statement releases the database connection resource when the variable goes out of scope.

This line opens the database connection.

Here we print the version of MySQL using the ServerVersionproperty of the connection object.

This is a sample output.

C# MySQL SELECT statement

The following example determines the version of MySQL with a SELECT statement.

Program.cs

We check for the version of the MySQL database. This time usingan SQL query.

This is the SQL SELECT statement. It returns the version of the database. TheVERSION() is a built-in MySQL function.

The MySqlCommand is an object which is used to execute a query onthe database. The parameters are the SQL statement and the connection object.

There are queries which return only a scalar value. In our case, we want asimple string specifying the version of the database. TheExecuteScalar() is used in such situations.

C# MySQL create table

In the following example, we create a database table and fill it with data.

In the example, we create a cars table with eight rows.

First we drop the table if it already exists. We use theExecuteNonQuery() method if we do not want a result set, forexample for DROP, INSERT, or DELETEstatements.

The cars table is created. The AUTO_INCREMENTkeyword makes the column auto-incremented in MySQL.

Here we insert two rows into the table.

We run the program.

We connect to the MySQL server with the mysql tool.

We verify the data. The cars table was successfully created.

C# MySQL prepared statements

Mac

Prepared statements increase security and performance. When we writeprepared statements, we use placeholders instead of directly writing thevalues into the statements.

Program.cs

We add a new car to the cars table. We use a parameterized command.

When we write prepared statements, we use placeholders instead of directlywriting the values into the statements. Prepared statements are faster and guardagainst SQL injection attacks. The @name and @priceare placeholders, which are going to be filled later.

Values are bound to the placeholders with the AddWithValue() method.

The prepared statement is executed. We use the ExecuteNonQuery()method of the MySQLCommand object when we don't expect any data tobe returned.

C# MySqlDataReader

The MySqlDataReader is an object used to retrieve data from thedatabase. It provides fast, forward-only, read-only access to query results. Itis the most efficient way to retrieve data from tables.

We get all rows from the cars table and print them to the console.

To create a MySQLDataReader, we call the ExecuteReader() method of the MySqlCommand object.

The Read() method advances the data reader to the next record. Itreturns true if there are more rows; otherwise false.We can retrieve the value using the array index notation, or use a specificmethod to access column values in their native data types. The latter is moreefficient.

This is the output of the example.

C# MySQL column headers

In the following example we print column headers with the data from a database table.

Program.cs

In the example, we select all rows from the cars table with theircolumn names.

We get the names of the columns with the GetName() method of the reader.

We print the data that was returned by the SQL statementto the terminal.

This is the output.
