You can select all records that are 10 minutes within current timestamp using the following syntax−
SELECT *FROM yourTableName WHERE yourColumnName > = DATE_SUB(NOW(),INTERVAL 10 MINUTE);
To understand the above syntax, let us create a table. The query to create a table is as follows−
mysql> create table users -> ( -> Id int NOT NULL AUTO_INCREMENT, -> UserName varchar(20), -> UserLastseen datetime, -> PRIMARY KEY(Id) -> ); Query OK, 0 rows affected (0.91 sec)
Insert some records in the table using insert command. The query is as follows−
mysql> insert into users(UserName,UserLastseen) values('Larry','2019-01-15 02−45−00');
Query OK, 1 row affected (0.15 sec)
mysql> insert into users(UserName,UserLastseen) values('Sam',now());
Query OK, 1 row affected (0.25 sec)
mysql> insert into users(UserName,UserLastseen) values('Mike','2019-01-15 02−30−00');
Query OK, 1 row affected (0.15 sec)
mysql> insert into users(UserName,UserLastseen) values('Bob','2019-01-15 15−02−00');
Query OK, 1 row affected (0.23 sec)
mysql> insert into users(UserName,UserLastseen) values('David','2019-01-15 14−55−00');
Query OK, 1 row affected (0.15 sec)Display all records from the table using select statement. The query is as follows−
mysql> select *from users;
The following is the output−
+----+----------+---------------------+ | Id | UserName | UserLastseen | +----+----------+---------------------+ | 1 | Larry | 2019-01-15 02−45−00 | | 2 | Sam | 2019-01-15 15−01−52 | | 3 | Mike | 2019-01-15 02−30−00 | | 4 | Bob | 2019-01-15 15−02−00 | | 5 | David | 2019-01-15 14−55−00 | +----+----------+---------------------+ 5 rows in set (0.00 sec)
Here is the query to select all records that are 10 minutes within the current timestamp−
mysql> select *from users -> where UserLastseen> = date_sub(now(),interval 10 minute);
The following is the output−
+----+----------+---------------------+ | Id | UserName | UserLastseen | +----+----------+---------------------+ | 2 | Sam | 2019-01-15 15−01−52 | | 4 | Bob | 2019-01-15 15−02−00 | | 5 | David | 2019-01-15 14−55−00 | +----+----------+---------------------+ 3 rows in set (0.00 sec)
