mysql ERROR 1364: 1364: Field 'mname' doesn't have a default value
我的系统是苹果os系统,我用的是mysql workbench,在插入数据的时候总会出现
ERROR 1364: 1364: Field 'mname' doesn't have a default value
请问我应该怎么解决
mysql ERROR 1364: 1364: Field 'mname' doesn't have a default
mname要有一个默认值,在数据库里的mname加一个0或null
再问： 就是说随便添加一个默认值就可以了吗
再答： 是的！数字就0,字串符就null吧
