STRICT_TRANS_TABLES:
在该模式下,如果一个值不能插入到一个事务表中,则中断当前的操作,对非事务表不做任何限制
NO_ZERO_IN_DATE:
在严格模式,不接受月或日部分为0的日期。如果使用IGNORE选项,我们为类似的日期插入'0000-00-00'。在非严格模式,可以接受该日期,但会生成警告。
NO_ZERO_DATE:
在严格模式,不要将 '0000-00-00'做为合法日期。你仍然可以用IGNORE选项插入零日期。在非严格模式,可以接受该日期,但会生成警告
实例验证:
1)设置sql_mode
set session sql_mode='STRICT_TRANS_TABLES,NO_ZERO_IN_DATE';
2)建表
create table t1(id int,age date);
insert into t1 values(1,'0000-00-00');
Query OK, 1 row affected (0.00 sec)
insert into t1 values(1,'0000-12-00');
ERROR 1292 (22007): Incorrect date value: '0000-12-00' for column 'age' at row 1
insert into t1 values(1,'0000-00-13');
ERROR 1292 (22007): Incorrect date value: '0000-00-13' for column 'age' at row 1
insert into t1 values(1,'0000-12-13');
Query OK, 1 row affected (0.00 sec)
insert into t1 values(1,'2000-00-00');
ERROR 1292 (22007): Incorrect date value: '2000-00-00' for column 'age' at row 1
insert into t1 values(1,'2000-00-12');
ERROR 1292 (22007): Incorrect date value: '2000-00-12' for column 'age' at row 1
insert into t1 values(1,'2000-12-00');
ERROR 1292 (22007): Incorrect date value: '2000-12-00' for column 'age' at row 1
3)结论:
在STRICT_TRANS_TABLES,NO_ZERO_IN_DATE模式下,只要日期的月和日中含有0值都报错,但是‘0000-00-00’除外
4)重新设置sql_mode
set session sql_mode='STRICT_TRANS_TABLES,NO_ZERO_DATE';
5)插入数据
insert into t1 values(1,'0000-00-00');
ERROR 1292 (22007): Incorrect date value: '0000-00-00' for column 'age' at row 1
insert into t1 values(1,'0000-12-00');
Query OK, 1 row affected (0.00 sec)
insert into t1 values(1,'0000-00-13');
Query OK, 1 row affected (0.00 sec)
insert into t1 values(1,'0000-12-13');
Query OK, 1 row affected (0.00 sec)
insert into t1 values(1,'2000-00-00');
Query OK, 1 row affected (0.00 sec)
insert into t1 values(1,'2000-00-12');
Query OK, 1 row affected (0.00 sec)
insert into t1 values(1,'2000-12-00');
Query OK, 1 row affected (0.00 sec)
6)结论
在STRICT_TRANS_TABLES,NO_ZERO_DATE模式下,只有‘0000-00-00’报错
7)设置sql_mode的值
set global sql_mode='STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE';
insert into t1 values(1,'0000-00-00');
ERROR 1292 (22007): Incorrect date value: '0000-00-00' for column 'age' at row 1
insert into t1 values(1,'0000-12-00');
ERROR 1292 (22007): Incorrect date value: '0000-12-00' for column 'age' at row 1
insert into t1 values(1,'0000-00-13');
ERROR 1292 (22007): Incorrect date value: '0000-00-13' for column 'age' at row 1
insert into t1 values(1,'0000-12-13');
Query OK, 1 row affected (0.01 sec)
insert into t1 values(1,'2000-00-00');
ERROR 1292 (22007): Incorrect date value: '2000-00-00' for column 'age' at row 1
insert into t1 values(1,'2000-00-12');
ERROR 1292 (22007): Incorrect date value: '2000-00-12' for column 'age' at row 1
insert into t1 values(1,'2000-12-00');
ERROR 1292 (22007): Incorrect date value: '2000-12-00' for column 'age' at row 1
8)总结
NO_ZERO_IN_DATE 支持 0000-00-00 0000-01-01 (年月日都为0,月日都不为0)插入表
NO_ZERO_DATE 支持 1000-00-00 0000-01-00 0000-00-01(年月日中任何一个不为0)插入表,年月日全为0报错
NO_ZERO_IN_DATE、NO_ZERO_DATE 同时设置 支持 0000-01-01 1000-01-01(只允许年为0)插入表
