Incorrect integer value: ''for column 'id' at row 1解决

 

最近在写个查询 插入语句的时候 我是这么写的 

insert into test values('',row[contentid],′".tn."'); 

 

 

结果搞死没插入进去  然后我 mysql_error() 了一下 就报 

 

Incorrect integer value: '' for column 'id' at row 1  这个错误

 

一般我们是认为应该没错误的。后来查了下MYSQL的资料。发现5以上的版本如果是空值应该要写NULL

 

这种问题一般mysql 5.x上出现。我用的mysql5.1

 

官方解释说:得知新版本mysql对空值插入有"bug",要在安装mysql的时候去除默认勾选的enable strict SQL mode

 

那么如果我们安装好了mysql怎么办了,解决办法是更改mysql中的配置 my.ini

 

my.ini中查找sql-mode,

 

默认为

sql-mode="STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION",

 

 

将其修改为

sql-mode="NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION",

 

 

重启mysql后即可

 

那么如果是虚拟主机或者是空间怎么办了。如果你能让空间商帮你改那是最好。

 

如果不能,那你就只能程序改改。都规范一点。空值就写 null 代替吧。
