我想改变mysql查询中的时间格式:
e_date_s = %m/%d/%Y
e_date_e = %m/%d/%Y
对此:
e_date_s = %Y/%m/%d
e_date_e = %Y/%m/%d
我的查询是:
$q3 = "SELECT c_m_vin, e_date_s,e_date_e FROM core
JOIN event_1 ON core.c_e_token = event_1.e_1_uniek WHERE ((e_date_s <= '$date')
AND (e_date_e >= '$date') AND (e_date_e LIKE '%$year%')
AND (c_m_vin = '$res1->m_vin'))";
我通过UNIX_TIMESTAMP看到了选项。有人理解吗?
更新
$q3 = "
SELECT c_m_vin,
DATE_FORMAT('e_date_s','%Y-%m-%d') AS e_date_s_new,
DATE_FORMAT('e_date_e','%Y-%m-%d') AS e_date_e_new
FROM core
JOIN event_1
ON core.c_e_token = event_1.e_1_uniek WHERE ((e_date_s_new <= '$date') AND (e_date_e_new >= '$date') AND (e_date_e_new LIKE '%$year%') AND (c_m_vin = '$res1->m_vin'))";

如果您的列是实际日期类型,您可以在select语句中使用MySQL DATE_FORMAT
函数直接在查询中设置日期格式。
SELECT DATE_FORMAT(e_date_s, "%Y/%m/%d") AS formatted_date
