Introduction
MySQL is a widely used open-source relational database management system. One of the most important data types in MySQL is the integer or whole number data type. In this article, we will explore the different types of integer data types in MySQL and their uses.
1. TINYINT
TINYINT is an integer data type that can store values between -128 and 127. It requires only one byte of storage space and is commonly used to represent boolean values (0 or 1).
2. SMALLINT
SMALLINT is an integer data type that can store values between -32768 and 32767. It requires two bytes of storage space and is commonly used for smaller numeric values.
3. MEDIUMINT
MEDIUMINT is an integer data type that can store values between -8388608 and 8388607. It requires three bytes of storage space and is commonly used for medium-sized numeric values.
4. INT
