Data types in MySQL are essential specifications that help SQL comprehend the nature of data anticipated within each column, facilitating how SQL will manage and manipulate the stored information. These data types in MySQL can be broadly categorized into three main groups:
String Data Types: These encompass various character-based data types like VARCHAR, CHAR, and TEXT, which are used for storing textual information such as names, descriptions, or addresses.
Numeric Data Types: This category includes data types like INT, DECIMAL, and FLOAT, which are employed to store numerical values like integers, decimals, or floating-point numbers for quantities, measurements, or calculations.
Date and Time Data Types: MySQL provides date and time data types like DATE, DATETIME, and TIMESTAMP to accurately handle temporal data, including dates, times, and timestamps for events, appointments, or recording when data was last modified.
These data types act as a foundation for defining the structure and constraints of database tables, ensuring data integrity and efficient data handling within MySQL databases.
