如何在MySQL查询的DATETIME字段中添加一天?
借助DATE_ADD()函数,我们可以将一天添加到表的DATETIME字段中。
mysql> Select StudentName, RegDate, Date_ADD(RegDate, INTERVAL +1 day) AS 'NEXT DAY'from testing where StudentName = 'gaurav';
+-------------+---------------------+---------------------+
| StudentName | RegDate | NEXT DAY |
+-------------+---------------------+---------------------+
| Gaurav | 2017-10-29 08:48:33 | 2017-10-30 08:48:33 |
+-------------+---------------------+---------------------+
1 row in set (0.00 sec)
以上查询将在RegDate中添加一天,其中MySQL表名为“ testing”的StudentName是Gaurav。
