What is MySQL?

MySQL is an open-source relational database management system (RDBMS) that uses Structured Query Language (SQL) to manage, manipulate, and retrieve data stored in relational databases.

How do I install MySQL?

Installation steps vary depending on the operating system. Generally, you download the MySQL installer from the official MySQL website and follow the installation wizard. For Linux systems, MySQL can often be installed via package managers.

What are the basic SQL queries I should know in MySQL?

The basic SQL queries include SELECT to retrieve data from the database, INSERT to add new records, UPDATE to modify existing records, DELETE to remove records, and CREATE TABLE to create new tables.

How do I create a database in MySQL?

To create a database, use the CREATE DATABASE statement, followed by the name of the database you want to create.

How do I back up a MySQL database?

You can back up a MySQL database using the mysqldump command-line utility, which creates a dump file containing SQL statements to recreate the database.

What is a primary key in MySQL?

A primary key is a unique identifier for a record in a database table. It ensures that each record can be uniquely identified by that key.

How do I join tables in MySQL?

You can join tables using the JOIN clause in a SELECT statement, specifying the condition that links your tables. Types of joins include INNER JOIN, LEFT JOIN, RIGHT JOIN, and FULL JOIN.

What are indexes in MySQL, and why are they important?

Indexes are special data structures that store a small portion of a table’s data in an easy-to-traverse form. They improve the speed of data retrieval operations on a database table at the cost of additional writes and storage space to maintain them.

How can I improve the performance of my MySQL queries?

To improve performance, you can optimize your queries by using indexes, avoiding unnecessary columns in SELECT statements, reducing the use of subqueries, and using query caching.

What is normalization, and why is it important in MySQL?

Normalization is the process of organizing data in a database to reduce redundancy and improve data integrity. It involves dividing large tables into smaller, interrelated tables and defining relationships between them.
