为毛不能给类型为datetime的字段插入date("Y-m-d H:i:s"),

Jun 23, 2016 pm 02:08 PM

为毛不能给类型为datetime的字段插入date("Y-m-d H:i:s"),
timestamp类型的却可以呢?

$re=mysql_query('insert into ook (xx) values (date("Y-m-d H:i:s"))');


回复讨论(解决方案)

$re = mysql_query('insert into ook (xx) values ( \'' . date("Y-m-d H:i:s") .'\')');

在单引号里面date函数不能解析了

弄个变量
$date=date("Y-m-d H:i:s");
然后放到sql里

你使用 date("Y-m-d H:i:s") 只是对数据库date字段内容格式的一种转换,你没有给它字段名当然是错误的了。

$re = mysql_query("insert into ook (xx) values ('". date("Y-m-d H:i:s") ."')"); 
SQL语句用"双引号比较方便点,因为插入的是除整形之类的数字的话,都得用到'单引号
还有就是一般插入的值用'单引号比较好,就懒得想是否应该加单引号的问题了

我原以为双引号可解析变量,
也可以解析函数的执行。。
