Display records by grouping dates in MySQL
To group dates in MySQL, use the GROUP BY clause −
mysql> create table DemoTable2002 ( CustomerName varchar(20), CustomerShippingDate datetime ); Query OK, 0 rows affected (0.61 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable2002 values('Chris','2019-01-10');
Query OK, 1 row affected (0.17 sec)
mysql> insert into DemoTable2002 values('David','2018-12-31');
Query OK, 1 row affected (0.14 sec)
mysql> insert into DemoTable2002 values('David','2019-12-16');
Query OK, 1 row affected (0.14 sec)
mysql> insert into DemoTable2002 values('Chris','2018-12-01');
Query OK, 1 row affected (0.12 sec)Display all records from the table using select statement −
mysql> select * from DemoTable2002;
This will produce the following output −
+--------------+----------------------+ | CustomerName | CustomerShippingDate | +--------------+----------------------+ | Chris | 2019-01-10 00:00:00 | | David | 2018-12-31 00:00:00 | | David | 2019-12-16 00:00:00 | | Chris | 2018-12-01 00:00:00 | +--------------+----------------------+ 4 rows in set (0.00 sec)
Here is the query to display records by grouping dates −
mysql> select date(min(CustomerShippingDate)),date(max(CustomerShippingDate)),CustomerName from DemoTable2002 group by CustomerName;
This will produce the following output −
+---------------------------------+---------------------------------+--------------+ | date(min(CustomerShippingDate)) | date(max(CustomerShippingDate)) | CustomerName | +---------------------------------+---------------------------------+--------------+ | 2018-12-01 | 2019-01-10 | Chris | | 2018-12-31 | 2019-12-16 | David | +---------------------------------+---------------------------------+--------------+ 2 rows in set (0.00 sec)
