How to fetch the newly added records from a MySQL table?
For this, you can use ORDER BY with LIMIT. Here, LIMIT is used to set the limit (count) of records you want to fetch. Let us first create a table −
mysql> create table DemoTable1486 -> ( -> StudentId int NOT NULL AUTO_INCREMENT PRIMARY KEY, -> StudentName varchar(20) -> ); Query OK, 0 rows affected (0.66 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable1486(StudentName) values('Chris Brown');
Query OK, 1 row affected (0.14 sec)
mysql> insert into DemoTable1486(StudentName) values('David Miller');
Query OK, 1 row affected (0.11 sec)
mysql> insert into DemoTable1486(StudentName) values('John Doe');
Query OK, 1 row affected (0.10 sec)
mysql> insert into DemoTable1486(StudentName) values('John Smith');
Query OK, 1 row affected (0.12 sec)
mysql> insert into DemoTable1486(StudentName) values('Adam Smith');
Query OK, 1 row affected (0.10 sec)
mysql> insert into DemoTable1486(StudentName) values('Carol Taylor');
Query OK, 1 row affected (0.16 sec)Display all records from the table using select statement −
mysql> select * from DemoTable1486;
This will produce the following output −
+-----------+--------------+ | StudentId | StudentName | +-----------+--------------+ | 1 | Chris Brown | | 2 | David Miller | | 3 | John Doe | | 4 | John Smith | | 5 | Adam Smith | | 6 | Carol Taylor | +-----------+--------------+ 6 rows in set (0.00 sec)
Here is the query to get the newly added records −
mysql> select * from DemoTable1486 -> order by StudentId desc -> limit 3;
This will produce the following output −
+-----------+--------------+ | StudentId | StudentName | +-----------+--------------+ | 6 | Carol Taylor | | 5 | Adam Smith | | 4 | John Smith | +-----------+--------------+ 3 rows in set (0.00 sec)
