php – Mysql int(11) number out of range

Posted by: admin April 23, 2020 Leave a comment

Questions:

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?

How to&Answers:

An int, with MySQL, is stored on 4 bytes, and, as such, can only contain values between -2147483648 and 2147483647.

622108120237 is greater than 2147483647 ; so it doesn’t fit into an int — looks like you are going to have to use a bigint.

See the Datatypes – Numeric types section of

the MySQL manual, about that.

Answer:

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.

Answer:

The maximum value you can store in an signed integer is 2147483647
And unsigned int is 4294967295 in Both case you exceed the limit
