mysql的boolean和tinyint(1)

boolean类型
MYSQL保存BOOLEAN值时用1代表TRUE,0代表FALSE，boolean在MySQL里的类型为tinyint(1),
MySQL里有四个常量：true,false,TRUE,FALSE,它们分别代表1,0,1,0，
mysql> select true,false,TRUE,FALSE;
+------+-------+------+-------+
| TRUE | FALSE | TRUE | FALSE |
+------+-------+------+-------+
| 1 | 0 | 1 | 0 |
+------+-------+------+-------+
可以如下插入boolean值：insert into [xxxx(xx)] values(true)，当然也可以values(1);
举例如下：
mysql> alter table test add isOk boolean;
Query OK
mysql> desc test;
+-------+-------------+------+-----+---------+----------------+
| Field | Type | Null | Key | Default | Extra |
+-------+-------------+------+-----+---------+----------------+
| id | int(11) | NO | PRI | NULL | auto_increment |
| isOk | tinyint(1) | YES | | NULL | |
+-------+-------------+------+-----+---------+----------------+
mysql> insert into test(isOk) values(true);
Query OK
mysql> select isOk from test ;
+------+
| isOk |
+------+
| 1 |
+------+

java中的对应的mysql的tinyint(1)类型为boolean型
