Mysql int(11) number out of range

Question

I have a column which is set to int(20) when I try and insert a number like 622108120237, it says it\'s out of range. Why?

Answer 1

See the MySQL Numeric Type Documentation. These things are well-documented.

The range for a signed INT is [-2147483648, 2147483647].

Note that in the case of INT(x), x is the "display width" and has nothing to do with the range or space requirements:

MySQL supports an extension for optionally specifying the display width of integer data types in parentheses following the base keyword for the type. For example, INT(4) specifies an INT with a display width of four digits ... display width does not constrain [or expand] the range of values that can be stored in the column.

Happy coding.
