Syntax

BIGINT[(M)] [SIGNED | UNSIGNED | ZEROFILL]

Description

A large integer. The signed range is -9223372036854775808 to 9223372036854775807. The unsigned range is 0 to 18446744073709551615.

If a column has been set to ZEROFILL, all values will be prepended by zeros so that the BIGINT value contains a number of M digits.

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