Let us first create a table −
mysql> create table DemoTable ( StudentId int NOT NULL AUTO_INCREMENT PRIMARY KEY, StudentName varchar(50), StudentAge int ); Query OK, 0 rows affected (0.72 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable(StudentName,StudentAge) values('Chris',21); Query OK, 1 row affected (0.12 sec) mysql> insert into DemoTable(StudentName,StudentAge) values('David',23); Query OK, 1 row affected (0.14 sec) mysql> insert into DemoTable(StudentName,StudentAge) values('Bob',22); Query OK, 1 row affected (0.17 sec) mysql> insert into DemoTable(StudentName,StudentAge) values('Carol',21); Query OK, 1 row affected (0.30 sec)
Display all records from the table using select statement −
mysql> select *from DemoTable;
This will produce the following output &minusl;
+-----------+-------------+------------+ | StudentId | StudentName | StudentAge | +-----------+-------------+------------+ | 1 | Chris | 21 | | 2 | David | 23 | | 3 | Bob | 22 | | 4 | Carol | 21 | +-----------+-------------+------------+ 4 rows in set (0.00 sec)
Following is the query to implement three conditions to fetch a particular record −
mysql> select *from DemoTable where StudentId=4 and StudentName='Carol' and StudentAge=21;
This will produce the following output −
+-----------+-------------+------------+ | StudentId | StudentName | StudentAge | +-----------+-------------+------------+ | 4 | Carol | 21 | +-----------+-------------+------------+ 1 row in set (0.00 sec)
