Is Real a Data Type in MySQL?


Larry Thompson

MySQL is a powerful relational database management system that is widely used for storing and managing data. When working with MySQL, you may come across various data types, such as integers, strings, dates, and more.

But what about the “real” data type? Is real a data type in MySQL? Let’s explore this further.

Understanding Data Types in MySQL

Before we dive into the “real” data type, let’s take a moment to understand the concept of data types in MySQL. A data type is a classification of values that determines the possible values that an object can hold. It also defines the operations that can be performed on those values.

In MySQL, there are several built-in data types available to store different kinds of information. These include numeric types like integer and decimal, string types like char and varchar, date and time types like date and datetime, and more.

The “Real” Data Type

Now let’s address the question at hand: is real a data type in MySQL? The short answer is no. Unlike some other databases, such as Microsoft SQL Server or Oracle, MySQL does not have a specific “real” data type.

However, MySQL does have similar numeric data types that can be used to store real numbers with decimal points. The most commonly used numeric types for storing real numbers in MySQL are:

  • Float: This type represents approximate floating-point numbers with a specified precision (e.g., FLOAT(10,2)).
  • Double: This type represents double-precision floating-point numbers with even greater precision than float (e., DOUBLE(15,3)).
  • Decimal: This type represents fixed-point numbers with a specified precision and scale (e., DECIMAL(8,4)).

These numeric types can be used to store real numbers in MySQL, depending on the required precision and range of values.


In conclusion, while MySQL does not have a specific “real” data type, it offers several numeric data types that can be used to store real numbers. The choice of which numeric type to use depends on the desired precision and range of values for your specific application.

Remember: Always choose the appropriate data type based on the nature of the data you need to store in your MySQL database. Using the correct data type ensures efficient storage and retrieval of information, as well as accurate calculations and comparisons.

I hope this article has provided you with a clear understanding of the “real” data type in MySQL. Happy coding!
