How to select record from last 6 months in a news table using MySQL?
To select the last 6 months records from news table, use the date_sub() function from MySQL since news records are arranged according to date.
The syntax is as follows −
select *from yourTableName where yourDateTimeColumnName >= date_sub(now(),interval 6 month);
To understand the above concept, let us first create a NEWS table with only NEWS ID and the date on which it published −
mysql> create table Newstable -> ( -> NewsId int, -> NewsDatetime datetime -> ); Query OK, 0 rows affected (0.66 sec)
Insert records in the table using insert command. The query is as follows −
mysql> insert into Newstable values(101,'2018-2-10'); Query OK, 1 row affected (0.18 sec) mysql> insert into Newstable values(102,'2018-12-10'); Query OK, 1 row affected (0.19 sec) mysql> insert into Newstable values(103,'2018-3-14'); Query OK, 1 row affected (0.14 sec) mysql> insert into Newstable values(104,'2018-12-12'); Query OK, 1 row affected (0.29 sec) mysql> insert into Newstable values(105,'2018-4-21'); Query OK, 1 row affected (0.09 sec) mysql> insert into Newstable values(106,'2018-6-30'); Query OK, 1 row affected (0.22 sec)
Display all records from the table using select statement. The query is as follows −
mysql> select *from Newstable;
Output
+--------+---------------------+ | NewsId | NewsDatetime | +--------+---------------------+ | 101 | 2018-02-10 00:00:00 | | 102 | 2018-12-10 00:00:00 | | 103 | 2018-03-14 00:00:00 | | 104 | 2018-12-12 00:00:00 | | 105 | 2018-04-21 00:00:00 | | 106 | 2018-06-30 00:00:00 | +--------+---------------------+ 6 rows in set (0.00 sec)
The following is the query to select last 6 months from the new table. The query is as follows −
mysql> select *from Newstable where NewsDatetime > date_sub(now(),Interval 6 month);
Output
+--------+---------------------+ | NewsId | NewsDatetime | +--------+---------------------+ | 102 | 2018-12-10 00:00:00 | | 104 | 2018-12-12 00:00:00 | | 106 | 2018-06-30 00:00:00 | +--------+---------------------+ 3 rows in set (0.00 sec)
