MySQL Tutorial

MySQL Tutorial

MySQL is the most popular and a free Open Source Relational Database Management System (RDBMS). An RDBMS system stores the data in the form of tables that might be related to each other. MySQL uses Structured Query Language (SQL) to store, manage and retrieve data, and control the accessibility to the data. It is one of the best RDBMS being used for developing web-based software applications.

MySQL is written in C and C++. Its SQL parser is written in yacc, but it uses a home-brewed lexical analyzer.

MySQL works on many system platforms, such as, Linux, macOS, Microsoft Windows, AIX, BSDi, FreeBSD, HP-UX, ArcaOS, eComStation, IBM i, IRIX, NetBSD, Novell NetWare, OpenBSD, OpenSolaris, OS/2 Warp, QNX, Oracle Solaris, Symbian, SunOS, SCO OpenServer, SCO UnixWare, Sanos and Tru64.

This tutorial will give you quick start with MySQL and make you comfortable with MySQL programming.

MySQL Examples

Consider an example table CUSTOMERS created in the MySQL database. This table contains the details of customers like ID, NAME, AGE, ADDRESS, SALARY.

ID	NAME	AGE	ADDRESS	SALARY
1	Ramesh	32	Ahmedabad	2000.00
2	Khilan	25	Delhi	1500.00
3	Kaushik	23	Kota	2000.00
4	Chaitali	25	Mumbai	6500.00
5	Hardik	27	Bhopal	8500.00
6	Komal	22	Hyderabad	4500.00
7	Muffy	24	Indore	10000.00

Since MySQL uses SQL to manage data, it also uses almost all DDL, DML and DCL statements. For instance, the following DML statement lists the records of all customers who are 25 years old.

SELECT*FROM CUSTOMERS WHERE AGE =25;

Following records are displayed as a result-set −

ID	NAME	AGE	ADDRESS	SALARY
2	Khilan	25	Delhi	1500.00
4	Chaitali	25	Mumbai	6500.00
