MySQL VIEW-এ WHERE ক্লজ ব্যবহার করা

MySQL VIEW-এ WHERE ক্লজ ব্যবহার করার সিনট্যাক্স:

select * from yourViewName where yourColumnName='yourValue';

প্রথমে একটি টেবিল তৈরি করি:

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)

রেকর্ড ইনসার্ট করি:

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)

সব রেকর্ড দেখি:

mysql> select * from DemoTable1432;

আউটপুট:

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

ভিউ তৈরি করি:

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

WHERE ক্লজ সহ ভিউ থেকে ডেটা ফেচ করি:

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

আউটপুট:

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