PHP按日期查詢

Question

如何在PHP中將此MySQL查詢更改爲僅顯示數據庫中名爲OpenHouseDate的日期列是當前日期還是前進的所有列表？

$sql_query = "SELECT * FROM listings ORDER BY RAND()"; 

Answer 1

如果OpenHouseDate是「日期」類型的，那麼你可以使用以下命令：

$sql_query = "SELECT * FROM listings WHERE OpenHouseDate <= CURDATE(); 

如果OpenHouseDate是「日期時間」類型，那麼你可以使用如下：

$sql_query = "SELECT * FROM listings WHERE OpenHouseDate <= NOW(); 

如果OpenHouseDate是'整數' 類型的，那麼你可以使用以下命令：

$sql_query = "SELECT * FROM listings WHERE OpenHouseDate <= UNIX_TIMESTAMP(NOW());
