How to use MySQL VIEW with WHERE clause?


For MySQL VIEW with WHERE clause, the syntax is as follows −

select * from yourViewName where yourColumnName='yourValue';

Let us first create a −

mysql> create table DemoTable1432
   -> (
   -> StudentId int NOT NULL AUTO_INCREMENT PRIMARY KEY,
   -> StudentName varchar(20),
   -> StudentBranchName varchar(20)
   -> );
Query OK, 0 rows affected (1.26 sec)

Insert some records in the table using insert −

mysql> insert into DemoTable1432(StudentName,StudentBranchName) values('Chris','CS');
Query OK, 1 row affected (0.14 sec)
mysql> insert into DemoTable1432(StudentName,StudentBranchName) values('David','CE');
Query OK, 1 row affected (0.23 sec)
mysql> insert into DemoTable1432(StudentName,StudentBranchName) values('Mike','ME');
Query OK, 1 row affected (0.20 sec)

Display all records from the table using select −

mysql> select * from DemoTable1432;

This will produce the following output −

+-----------+-------------+-------------------+
| StudentId | StudentName | StudentBranchName |
+-----------+-------------+-------------------+
|         1 | Chris       | CS                |
|         2 | David       | CE                |
|         3 | Mike        | ME                |
+-----------+-------------+-------------------+
3 rows in set (0.00 sec)

Following is the query to create view −

mysql> create view DemoTable1432_View as select * from DemoTable1432;
Query OK, 0 rows affected (0.17 sec)

Following is the query to use MySQL view with where clause −

mysql> select * from DemoTable1432_View where StudentBranchName='CS';

This will produce the following output −

+-----------+-------------+-------------------+
| StudentId | StudentName | StudentBranchName |
+-----------+-------------+-------------------+
|         1 | Chris       | CS                |
+-----------+-------------+-------------------+
1 row in set (0.03 sec)
