问题描述
我已经搜索了很长时间，但我不明白为什么我的查询不适用于日期.
I have been searching for quite a while now and I can't figure out why my query isn't working for dates.
我希望将它作为日期导入到我的数据库中，这是从更高层的选择，所以我在这里.
I want it to be imported to my database as a Date, this is a choice from higher up so here I am.
$insert_query = "INSERT INTO enrties(
`datum` )
VALUES (
'".mysql_real_escape_string($_SESSION['Datum'])."')
上面几页之前我用这段代码来填充$_SESSION
a few pages before the above i use this piece of code to fill the $_SESSION
$DateDag = $_POST['Dag'];
$DateMaand = $_POST['Maand'];
$DateJaar = $_POST['Jaar'];
switch ($dateMaand)
{
case 'Januari': $DateMaand = '01'; break;
case 'Februari': $DateMaand = '02'; break;
case 'Maart': $DateMaand = '03'; break;
case 'April': $DateMaand = '04'; break;
case 'Mei': $DateMaand = '05'; break;
case 'Juni': $DateMaand = '06'; break;
case 'July': $DateMaand = '07'; break;
case 'Augustus': $DateMaand = '08'; break;
case 'September': $DateMaand = '09'; break;
case 'Oktober': $DateMaand = '10'; break;
case 'November': $DateMaand = '11'; break;
case 'December': $DateMaand = '12'; break;
}
$_SESSION['Datum'] = $DateDag. '-'. $DateMaand. '-'. $DateJaar;
我想将日期导入为 SQL 日期格式(最好是 DD-MM-YYYY 格式).
I want to have the date imported as a SQL Date format (preferably DD-MM-YYYY format).
解决了，开关中出现了一个错误显然，不确定是什么，但它有效;)
SOLVED, there was a mistake in the switch Apparantly, not really sure what but it works ;)
推荐答案
MySQL 的日期格式实际上是 YYYY-MM-DD，所以如果你想插入一个日期(猜测你的数据字段是 Date 或 Datetime)你必须以这种方式设置您的字符串.
The MySQL date format is actually YYYY-MM-DD, so if you want to insert a date (guessing your datum field is Date or Datetime) you have to set up your string in that way.
如果你想以不同的方式插入你的日期，你应该使用这个:
If you want to insert your date in a different way you should use this:
INSERT INTO enrties (datum) VALUES (str_to_date('01/02/2000', '%d/%m/%Y'));
但这将始终以 YYYY-MM-DD 方式保存日期，因为这是 mysql 的默认设置.
but this will save always the date in YYYY-MM-DD way, since is the default for mysql.
