MySQL query to display the column and its values using OR in WHERE statement
Let us first create a table −
mysql> create table DemoTable777 ( StudentId int NOT NULL AUTO_INCREMENT PRIMARY KEY, StudentName varchar(100), StudentAge int ); Query OK, 0 rows affected (1.34 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable777(StudentName,StudentAge) values('Chris',23);
Query OK, 1 row affected (0.20 sec)
mysql> insert into DemoTable777(StudentName,StudentAge) values('Robert',21);
Query OK, 1 row affected (0.22 sec)
mysql> insert into DemoTable777(StudentName,StudentAge) values('Mike',19);
Query OK, 1 row affected (0.16 sec)
mysql> insert into DemoTable777(StudentName,StudentAge) values('Bob',22);
Query OK, 1 row affected (0.19 sec)Display all records from the table using select statement −
mysql> select *from DemoTable777;
This will produce the following output -
+-----------+-------------+------------+ | StudentId | StudentName | StudentAge | +-----------+-------------+------------+ | 1 | Chris | 23 | | 2 | Robert | 21 | | 3 | Mike | 19 | | 4 | Bob | 22 | +-----------+-------------+------------+ 4 rows in set (0.00 sec)
Following is the query to return all the columns using OR in WHERE statement −
mysql> select *from DemoTable777 where StudentId IN(1,2) OR StudentName='Mike' OR StudentAge=22;
This will produce the following output -
+-----------+-------------+------------+ | StudentId | StudentName | StudentAge | +-----------+-------------+------------+ | 1 | Chris | 23 | | 2 | Robert | 21 | | 3 | Mike | 19 | | 4 | Bob | 22 | +-----------+-------------+------------+ 4 rows in set (0.00 sec)
