Implement MySQL query using multiple OR statements. Any optimal alternative?

It would be good to use IN() instead of multiple OR statements. Let us first create a table −

mysql> create table DemoTable
   -> (
   -> Id int NOT NULL AUTO_INCREMENT PRIMARY KEY,
   -> FirstName varchar(20)
   -> );
Query OK, 0 rows affected (0.83 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable(FirstName) values('John');
Query OK, 1 row affected (0.12 sec)
mysql> insert into DemoTable(FirstName) values('Adam');
Query OK, 1 row affected (0.27 sec)
mysql> insert into DemoTable(FirstName) values('David');
Query OK, 1 row affected (0.09 sec)
mysql> insert into DemoTable(FirstName) values('Mike');
Query OK, 1 row affected (0.48 sec)
mysql> insert into DemoTable(FirstName) values('Bob');
Query OK, 1 row affected (0.09 sec)

Display all records from the table using select statement −

mysql> select *from DemoTable;

This will produce the following output −

+----+-----------+
| Id | FirstName |
+----+-----------+
| 1 | John       |
| 2 | Adam       |
| 3 | David      |
| 4 | Mike       |
| 5 | Bob        |
+----+-----------+
5 rows in set (0.00 sec)

Here is the query for using IN() −

mysql> select *from DemoTable where Id IN(2,3,5);

This will produce the following output −

+----+-----------+
| Id | FirstName |
+----+-----------+
| 2 | Adam       |
| 3 | David      |
| 5 | Bob        |
+----+-----------+
3 rows in set (0.00 sec)
