`BIT( > 1)` (new in MySQL-5.0)	`BIT`	`byte[]`
`TINYINT`	`TINYINT`	`java.lang.Boolean` if the configuration property `tinyInt1isBit` is set to `true` (the default) and the storage size is 1, or `java.lang.Integer` if not.
`BOOL`, `BOOLEAN`	`TINYINT`	See `TINYINT`, above as these are aliases for `TINYINT(1)`, currently.
`SMALLINT[(M)] [UNSIGNED]`	`SMALLINT [UNSIGNED]`	`java.lang.Integer` (regardless of whether it is `UNSIGNED` or not)
