MySQL query to sort by both timestamp and enum?
For this, you can use ORDER BY DATE(). Let us first create a table. Here, we have a column with type DATE and another with type ENUM −
mysql> create table DemoTable
-> (
-> JoiningDate date,
-> Status ENUM('Good','Excellent','Bad')
-> );
Query OK, 0 rows affected (0.58 sec)Insert some records in the table using insert command −
mysql> insert into DemoTable values('2019-01-21','Excellent');
Query OK, 1 row affected (0.17 sec)
mysql> insert into DemoTable(Status) values('Bad');
Query OK, 1 row affected (0.17 sec)
mysql> insert into DemoTable(Status) values('Good');
Query OK, 1 row affected (0.13 sec)Display all records from the table using select statement −
mysql> select *from DemoTable;
This will produce the following output −
+-------------+-----------+ | JoiningDate | Status | +-------------+-----------+ | 2019-01-21 | Excellent | | NULL | Bad | | NULL | Good | +-------------+-----------+ 3 rows in set (0.00 sec)
Here is the query to sort order by both timestamp and enum −
mysql> select *from DemoTable -> order by DATE(JoiningDate) ASC, Status asc;
This will produce the following output −
+-------------+-----------+ | JoiningDate | Status | +-------------+-----------+ | NULL | Good | | NULL | Bad | | 2019-01-21 | Excellent | +-------------+-----------+ 3 rows in set (0.00 sec)
