Exploring MySQL INT Max Value: Signed and Unsigned Limits
February 18, 2024
In MySQL, understanding the maximum value of the [INT
data type](https://www.basedash.com/blog/what-is-mysql-int-data-type) is essential for designing efficient database schemas and ensuring data integrity. Let's explore the maximum values for both signed and unsigned INT
types.
What is signed INT
max value in MySQL?
The maximum value for a signed INT
in MySQL is 2,147,483,647. This is because a signed INT
uses 4 bytes, and one bit is reserved for the sign, reducing the maximum positive value by 1.
CREATE TABLE example_table ( id INT );
What is unsigned INT
max value in MySQL?
If you need to store only non-negative values, you can use an unsigned INT
, which effectively doubles the maximum value to 4,294,967,295.
CREATE TABLE example_table ( id INT UNSIGNED );
Stuff to keep in mind:
- Choosing between signed and unsigned
INT
depends on your data requirements. If you need to store negative values, use a signedINT
. - Be mindful of the data range and potential overflow issues when working with integer values close to the maximum limit.
