How to find the previous and next record using a single query in MySQL?

You can use UNION to get the previous and next record in MySQL.

The syntax is as follows

(select *from yourTableName WHERE yourIdColumnName > yourValue ORDER BY
yourIdColumnName ASC LIMIT 1)
UNION
(select *from yourTableName WHERE yourIdColumnName < yourValue ORDER BY
yourIdColumnName DESC LIMIT 1);

To understand the concept, let us create a table. The query to create a table is as follows

mysql> create table previousAndNextRecordDemo
   - > (
   - > Id int NOT NULL AUTO_INCREMENT PRIMARY KEY,
   - > Name varchar(30)
   - > );
Query OK, 0 rows affected (1.04 sec)

Insert some records in the table using insert command.

The query is as follows

mysql> insert into previousAndNextRecordDemo(Name) values('John');
Query OK, 1 row affected (0.17 sec)
mysql> insert into previousAndNextRecordDemo(Name) values('Sam');
Query OK, 1 row affected (0.15 sec)
mysql> insert into previousAndNextRecordDemo(Name) values('Carol');
Query OK, 1 row affected (0.14 sec)
mysql> insert into previousAndNextRecordDemo(Name) values('Bob');
Query OK, 1 row affected (0.17 sec)
mysql> insert into previousAndNextRecordDemo(Name) values('Larry');
Query OK, 1 row affected (0.20 sec)
mysql> insert into previousAndNextRecordDemo(Name) values('David');
Query OK, 1 row affected (0.14 sec)
mysql> insert into previousAndNextRecordDemo(Name) values('Ramit');
Query OK, 1 row affected (0.12 sec)
mysql> insert into previousAndNextRecordDemo(Name) values('Maxwell');
Query OK, 1 row affected (0.15 sec)
mysql> insert into previousAndNextRecordDemo(Name) values('Mike');
Query OK, 1 row affected (0.14 sec)
mysql> insert into previousAndNextRecordDemo(Name) values('Robert');
Query OK, 1 row affected (0.19 sec)
mysql> insert into previousAndNextRecordDemo(Name) values('Chris');
Query OK, 1 row affected (0.10 sec)
mysql> insert into previousAndNextRecordDemo(Name) values('James');
Query OK, 1 row affected (0.16 sec)
mysql> insert into previousAndNextRecordDemo(Name) values('Jace');
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 previousAndNextRecordDemo;

The following is the output

+----+---------+
| Id | Name    |
+----+---------+
|  1 | John    |
|  2 | Sam     |
|  3 | Carol   |
|  4 | Bob     |
|  5 | Larry   |
|  6 | David   |
|  7 | Ramit   |
|  8 | Maxwell |
|  9 | Mike    |
| 10 | Robert  |
| 11 | Chris   |
| 12 | James   |
| 13 | Jace    |
+----+---------+
13 rows in set (0.00 sec)

Here is the query to get previous and next record using a single query with UNION

mysql> (select *from previousAndNextRecordDemo WHERE Id > 8 ORDER BY Id ASC LIMIT 1)
   - > UNION
   - > (select *from previousAndNextRecordDemo WHERE Id < 8 ORDER BY Id DESC LIMIT 1);

The following is the output

+----+-------+
| Id | Name  |
+----+-------+
|  9 | Mike  |
|  7 | Ramit |
+----+-------+
2 rows in set (0.03 sec)
