MySQL 如何显示下一个星期日的日期

首先让我们创建一个表 –

mysql> create table DemoTable(GetSundayDate date);
Query OK, 0 rows affected (0.44 sec)

使用insert命令将一些记录插入表中 –

mysql> insert into DemoTable values('2019-08-07');
Query OK, 1 row affected (0.19 sec)
mysql> insert into DemoTable values('2018-09-05');
Query OK, 1 row affected (0.22 sec)
mysql> insert into DemoTable values('2019-09-12');
Query OK, 1 row affected (0.17 sec)

使用select语句显示表中的所有记录 –

mysql> select *from DemoTable;

这将产生以下输出 –

+---------------+
| GetSundayDate |
+---------------+
| 2019-08-07    |
| 2018-09-05    |
| 2019-09-12    |
+---------------+
3 rows in set (0.00 sec)

以下是获取此列中所有日期的下一个星期日的查询 –

mysql> SELECT date(GetSundayDate + INTERVAL 6 - weekday(GetSundayDate) DAY) AS ComingSundayDate from DemoTable;

这将产生以下输出 –

+------------------+
| ComingSundayDate |
+------------------+
| 2019-08-11       |
| 2018-09-09       |
| 2019-09-15       |
+------------------+
3 rows in set (0.00 sec)
