In MySQL, the maximum value that an INT can store depends on the size of the column. By default, an INT column is a 4-byte signed integer, which means it can store values from -2,147,483,648 to 2,147,483,647. This range is based on the way the data is stored in memory.
However, if you want to store only positive values, you can use the UNSIGNED keyword when defining the column. With UNSIGNED , the maximum value that an INT column can store becomes 4,294,967,295, which is the maximum value of an unsigned 4-byte integer.
If you need to store larger values, you can use a larger integer type like BIGINT , which is an 8-byte signed integer and can store values from -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807. If you use BIGINT UNSIGNED , the maximum value that can be stored becomes 18,446,744,073,709,551,615, which is the maximum value of an unsigned 8-byte integer.
Keep in mind that using larger integer types will increase the storage space required for each row. This can have an impact on database performance and storage requirements. Therefore, it's important to choose the appropriate data type for your needs to avoid unnecessary storage costs and performance issues.
