INT

Syntax

INT[(M)] [SIGNED | UNSIGNED | ZEROFILL]
INTEGER[(M)] [SIGNED | UNSIGNED | ZEROFILL]

Description

A normal-size integer. When marked UNSIGNED, it ranges from 0 to 4294967295, otherwise its range is -2147483648 to 2147483647 (SIGNED is the default). If a column has been set to ZEROFILL, all values will be prepended by zeros so that the INT value contains a number of M digits. INTEGER is a synonym for INT.

Note: If the ZEROFILL attribute has been specified, the column will automatically become UNSIGNED.

For details on the attributes, see Numeric Data Type Overview.
