According to official MySQL documentation, the maximum value of an unsigned smallint is 65535.
根据官方 MySQL 文档，unsigned smallint 的最大值为65535。
The (6)portion has no effect on the allowed range of the column; it only affects the display of the column in the MySQL command line interface.
该(6)部分对列的允许范围没有影响；它只影响 MySQL 命令行界面中列的显示。
