如果存在两行,价值等于数据库价值,则从数据库获得价值
原标题:get value from database if two rows exist and value is equal to

试图检查的Im是数据库中存在一行的价值,如果存在的话,就会检查第二行的价值,如果存在的话,就会检查第三行的价值。 (我想,没有经过纠正)。

表格上的三行“注”[习俗]、[创造时间]和[地位]

我需要检查数据库是否存在[习惯]。

$notes = mysql_query("SELECT * FROM `notes` WHERE `custom` =  $custom ")

然后,如果数据库中存在美元基数,则需要核对<代码>[创建时间]的账面少于3天。 <代码>[设定时间] 具有Y-m-d等值 H:i:s

如果是ok(价值少于3天),则需要获得<代码>[状况]的价值。

Any one can point to a suitable example of how to perform that check or similar. I like to learn not to copy and paste, so any reference to a suitable example will be really appreciated, Examples or solutions are also welcome

最佳回答

你们可以利用一个问询来做到这一点,例如:

SELECT `status` FROM `notes` WHERE `custom` =  $custom  AND `createdTime` > (CURRENT_DATE - INTERVAL 3 DAY);
