- Q1. Can we update view in SQl
- Ans.
Yes, views can be updated in SQL.
Views can be updated in SQL by using the CREATE OR REPLACE VIEW statement.
The data in the underlying tables will be affected when the view is updated.
Views can be updated to include new columns or filter criteria.
Example: CREATE OR REPLACE VIEW my_view AS SELECT * FROM my_table WHERE column = 'value';
- Q2. What are different types of Trigger
- Ans.
Types of triggers include DML triggers, DDL triggers, and logon triggers.
DML triggers are fired in response to data manipulation language (DML) events like INSERT, UPDATE, DELETE.
DDL triggers are fired in response to data definition language (DDL) events like CREATE, ALTER, DROP.
Logon triggers are fired in response to a LOGON event.
INSTEAD OF triggers are used to perform an action instead of the triggering action.
- Q3. Does view improve query performance
- Ans.
Views can improve query performance by simplifying complex queries and reducing the need for redundant code.
Views can store complex queries and calculations, allowing for easier access and reuse of data.
Views can help optimize performance by pre-aggregating data or joining tables in advance.
Views can reduce the need for writing repetitive code by encapsulating common logic.
However, views can also introduce overhead if ...
- Q4. Why it is not recommended to give store procedure name with sp_ prefix
- Ans.
Using sp_ prefix for stored procedures can cause performance issues and conflicts with system procedures.
sp_ prefix is reserved for system stored procedures in SQL Server, so using it for user-defined procedures can lead to conflicts.
Using sp_ prefix can cause unnecessary overhead as SQL Server first searches in the master database for system procedures before looking in the user database.
Avoiding sp_ prefix can improv...

- Q1. What is closure
- Ans.
A closure is a function that has access to its own scope, the scope in which it was defined, and the global scope.
A closure is created when a function is defined inside another function.
The inner function has access to the variables and parameters of the outer function, even after the outer function has finished executing.
Closures are useful for creating private variables and functions in JavaScript.

- Q2. What is Encapsulation
- Ans.
Encapsulation is the process of hiding internal details and providing a public interface for accessing and manipulating data.
Encapsulation bundles data and methods together into a single unit.
It helps in achieving data abstraction and data hiding.
By encapsulating data, we can control access to it and prevent unauthorized modifications.
Encapsulation promotes code reusability and maintainability.
Example: A class in objec...
- Q3. What is Inheritance
- Ans.
Inheritance is a concept in object-oriented programming where a class inherits properties and behaviors from another class.
Inheritance allows for code reuse and promotes the concept of hierarchy.
The class that is being inherited from is called the superclass or base class.
The class that inherits from the superclass is called the subclass or derived class.
The subclass can access the public and protected members of the s...
- Q4. What is Abstraction
- Ans.
Abstraction is the process of simplifying complex systems by focusing on essential details.
Abstraction involves hiding unnecessary details and exposing only relevant information.
It allows developers to create models or representations that capture the essential aspects of a system.
Abstraction helps in managing complexity, improving code reusability, and enhancing maintainability.
For example, in object-oriented programm...
- Q5. What is Polymorphism
- Ans.
Polymorphism is the ability of an object to take on many forms. It allows objects of different classes to be treated as the same type.
Polymorphism is a fundamental concept in object-oriented programming.
It enables code reusability and flexibility.
Polymorphism can be achieved through method overriding and method overloading.
Example: A parent class Animal can have multiple child classes like Dog, Cat, and Bird. They can ...
