Update table and order dates in MySQL
You cannot use UPDATE command with ORDER BY clause, but you can use SELECT statement with ORDER BY DESC.
Let us first create a −
mysql> create table DemoTable1403 -> ( -> DueDate timestamp -> ); Query OK, 0 rows affected (1.26 sec)
Insert some records in the table using insert −
mysql> insert into DemoTable1403 values('2019-09-29');
Query OK, 1 row affected (0.31 sec)
mysql> insert into DemoTable1403 values('2016-02-21');
Query OK, 1 row affected (0.31 sec)
mysql> insert into DemoTable1403 values('2018-01-31');
Query OK, 1 row affected (0.65 sec)
mysql> insert into DemoTable1403 values('2017-12-01');
Query OK, 1 row affected (0.27 sec)Display all records from the table using select −
mysql> select * from DemoTable1403;
This will produce the following output −
+---------------------+ | DueDate | +---------------------+ | 2019-09-29 00:00:00 | | 2016-02-21 00:00:00 | | 2018-01-31 00:00:00 | | 2017-12-01 00:00:00 | +---------------------+ 4 rows in set (0.00 sec)
Here is the query to order dates with ORDER BY −
mysql> select * from DemoTable1403 order by DueDate DESC;
This will produce the following output −
+---------------------+ | DueDate | +---------------------+ | 2019-09-29 00:00:00 | | 2018-01-31 00:00:00 | | 2017-12-01 00:00:00 | | 2016-02-21 00:00:00 | +---------------------+ 4 rows in set (0.00 sec)
