[b]问题补充：[/b]
thank you very much ,i am tesing with your method.
数据库字段有问题。可能你的sql建表没有设置默认值，但是插入时候也没有赋值。
在mysql的严格模式下可能就会出这样的错误。
MySQL 5 uses a strict mode which needs to be disabled.
In Windows, Goto Start-->Programs-->MySQL->MySQL Instance Config Wizard. Follow through the Reconfigure Instance option-->Detailed Configuration-->Continue Next a few screens. At the bottom under Enable TCP/IP option there is 'Enable Strict Mode'. Deslect this option (no tick). Save changes and MySQL will restart.
你也可以试试，删除数据表再重新建一下。
