[MySQL学习]STRICT_ALL_TABLES对应的OUT of RANGE VALUE FOR COLUMN和DATA truncated FOR COLUMN

标签：mysql   1264   1265   sql_mode   

昨天在存储过程中用了语句insert into a select from b。在应用中发现bigint字段插入到int字段的时候，数值被截断了，插入后已经不是所要的值。因为存储过程中没有用到异常捕捉的处理，所以一开始并未发现错误，只是在比对数据的时候才发现不对。后来比对了两张表，才发现是字段类型不一样。接下来就试着验证了一下（window下的测试环境）。

创建两张表

CREATE TABLE T_INT(id INT ,vname VARCHAR(20));
CREATE TABLE T_BIGINT(id BIGINT ,vname VARCHAR(40));

</pre><p></p><p></p><pre code_snippet_id="397037" snippet_file_name="blog_20140618_3_2598704" name="code" class="sql">INSERT INTO t_int(id,vname)VALUES(POWER(2,31),'0123456789abcdefghij');

SHOW WARNINGS;
1264 OUT of RANGE VALUE FOR COLUMN 'id' AT ROW 1;

SELECT * FROM t_int;
SELECT POWER(2,31)
2147483648
2147483647

INSERT INTO t_int(id,vname)VALUES(POWER(2,31),'0123456789abcdefghij1');
SHOW WARNINGS;
1264 OUT of RANGE VALUE FOR COLUMN 'id' AT ROW 1;
1265 DATA truncated FOR COLUMN 'vname' AT ROW 1;

id	vname
2147483647	0123456789abcdefghij
2147483647	0123456789abcdefghij

INSERT INTO T_BIGINT(id,vname)VALUES(POWER(2,31),'0123456789abcdefghij1');
INSERT INTO t_int SELECT * FROM t_bigint;

因为我用的是SQLyog，默认的模式是空，所以在这个上面调试的时候，就出问题了。在应用中出错，是因为我的url中没有指定客户端的sql_mode。

/*[17:15:32][  31 ms]*/ SHOW VARIABLES LIKE 'lower_case_table_names';
/*[17:15:32][   0 ms]*/ SET NAMES 'utf8';
/*[17:15:32][   0 ms]*/ SET sql_mode='';
/*[17:15:32][  16 ms]*/ SHOW DATABASES;

在cmd下直接连接MySQL是不会有问题，因为我已经在配置文件中配置了sql_mode。

mysql> INSERT INTO t_int(id,vname)VALUES(POWER(2,31),'0123456789abcdefghij');
ERROR 1264 (22003): Out of range value for column 'id' at row 1

但是如果将insert语句封装到存储过程中，不会报错，只会有有警告。

mysql> call PRO_INSERT();
Query OK, 1 row affected, 3 warnings (0.01 sec)

mysql> select * from t_int;

mysql> set sql_mode='STRICT_ALL_TABLES';

解决方案，直接抛错。在存储过程中SET sql_mode=‘STRICT_TRANS_TABLES,NO_ENGINE_SUBSTITUTION‘;（昨天晚听课时叶总提醒，在存储过程中set sql_mode）

mysql> call PRO_INSERT();
Query OK, 1 row affected, 3 warnings (0.01 sec)

mysql> show warnings;
+---------+------+---------------------------------------------+

| Warning | 1264 | Out of range value for column 'id' at row 2 |

+---------+------+---------------------------------------------+
