Sort by date & time in descending order in MySQL?
Let us create a table to sort date and time in ascending order. The query to create a table is as follows −
mysql> create table SortByDateAndTime -> ( -> UserId int, -> UserName varchar(100), -> IssueDate date, -> IssueTime time -> ); Query OK, 0 rows affected (0.60 sec)
Insert the records in the table using insert command. The query is as follows −
mysql> insert into SortByDateAndTime values(1,'John','2018-12-16','10:30'); Query OK, 1 row affected (0.14 sec) mysql> insert into SortByDateAndTime values(2,'Bob','2018-12-16','10:10'); Query OK, 1 row affected (0.14 sec) mysql> insert into SortByDateAndTime values(3,'Carol','2018-12-16','10:20'); Query OK, 1 row affected (0.10 sec) mysql> insert into SortByDateAndTime values(4,'Sam','2018-12-16','10:00'); Query OK, 1 row affected (0.15 sec)
The query to display all records from the table using select statement is as follows −
mysql> select *from SortByDateAndTime;
Output
+--------+----------+------------+-----------+ | UserId | UserName | IssueDate | IssueTime | +--------+----------+------------+-----------+ | 1 | John | 2018-12-16 | 10:30:00 | | 2 | Bob | 2018-12-16 | 10:10:00 | | 3 | Carol | 2018-12-16 | 10:20:00 | | 4 | Sam | 2018-12-16 | 10:00:00 | +--------+----------+------------+-----------+ 4 rows in set (0.00 sec)
Here is the query to sort date and time in descending order −
mysql> select UserId,UserName,date(IssueDate) as date1,IssueTime from SortByDateAndTime -> order by date(IssueDate)desc,IssueTime desc;
The following is the output displaying in sorted date and time −
+--------+----------+------------+-----------+ | UserId | UserName | date1 | IssueTime | +--------+----------+------------+-----------+ | 1 | John | 2018-12-16 | 10:30:00 | | 3 | Carol | 2018-12-16 | 10:20:00 | | 2 | Bob | 2018-12-16 | 10:10:00 | | 4 | Sam | 2018-12-16 | 10:00:00 | +--------+----------+------------+-----------+ 4 rows in set (0.00 sec)
Or you can use another query to sort date and time. The query is as follows −
mysql> select UserId,UserName,date(IssueDate) as date1,IssueTime from SortByDateAndTime -> order by date(IssueDate) desc,IssueTime asc;
Output
+--------+----------+------------+-----------+ | UserId | UserName | date1 | IssueTime | +--------+----------+------------+-----------+ | 4 | Sam | 2018-12-16 | 10:00:00 | | 2 | Bob | 2018-12-16 | 10:10:00 | | 3 | Carol | 2018-12-16 | 10:20:00 | | 1 | John | 2018-12-16 | 10:30:00 | +--------+----------+------------+-----------+ 4 rows in set (0.00 sec)
