Syntax

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

Description

A small integer. The signed range is -32768 to 32767. The unsigned range is 0 to 65535.

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

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

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