Introduction to CRUD Operations
CRUD operations stand at the core of database management and are fundamental in interacting with data. CRUD is an acronym for Create, Read, Update, and Delete, representing the four basic functions we can perform on a database.
- Create: This operation involves creating new objects in a database server. An object can be a database, a table, or a row. In MySQL, these operations are performed using the
CREATE
orINSERT
statements; - Read: Reading data involves retrieving existing records from the database. In MySQL, the
SELECT
statement is used to fetch data from one or more tables; - Update: Updating data involves modifying existing records in the database. In MySQL, the
UPDATE
statement is used for updating records; - Delete: Deleting data involves removing existing records from the database. It can also include deleting entire tables or perhaps database instances. In MySQL, the
DELETE
orDROP
statements are used to delete objects.
Understanding how to perform CRUD operations is essential for working with MySQL databases. These operations enable developers to create, retrieve, update, and delete data efficiently, forming the backbone of many database-driven applications. Throughout this guide, we'll explore each CRUD operation in detail, along with practical examples in MySQL.
