timestamp的默认值是插入数据库的时间吧,不用指定都可以的。 A TIMESTAMP column is useful for recording the date and time of an INSERT or UPDATE operation. By default, the first TIMESTAMP column in a table is automatically set to the date and time of the most recent operation if you do not assign it a value yourself. You can also set any TIMESTAMP column to the current date and time by assigning it a NULL value. 在08-1-27,realfun <realfun在gmail.com> 写道: > > 1. 我用的是http://mysql-python.sourceforge.net/MySQLdb.html, 大家都用这个吗? > 2. > 我看mysql书上提到默认值和auto_increment的值,但是我用mysqldb的execute去insert一行的时候,总出错,所以有两个小问题: > 不知道怎么才能传个NULL给mysql? > 怎么才能让timestamp的属性自动存储为当前时间?我试过"NOW()", "NULL", 0, 都不行。 > mysql-python自带的文档太简略了,啥也没查到 > > 有没有熟悉的帮帮忙哈。 > > -- > http://www.2maomao.com/blog > _______________________________________________ > python-chinese > Post: send python-chinese在lists.python.cn > Subscribe: send subscribe to python-chinese-request在lists.python.cn > Unsubscribe: send unsubscribe to python-chinese-request在lists.python.cn > Detail Info: http://python.cn/mailman/listinfo/python-chinese > -------------- 下一部分 -------------- 一个HTML附件被移除...
