Top 10 Questions for Shrouder Interview

1. What is the difference between a full join and a left join?

A full join returns all rows from both tables, even if there is no match in the other table. A left join returns all rows from the left table, and any matching rows from the right table. If there is no match in the right table, the right-hand side data will be null. Full join uses CROSS JOIN internally and it can show the unmatched rows of both the tables.

2. What is the purpose of using an index in a database?

Improves Query Performance

• Indexes speed up query execution by reducing the number of disk seeks required to retrieve data.
• Indexes create a sorted order of data, allowing for faster data retrieval.

Reduces I/O Operations

• Indexes minimize the amount of data that needs to be read from disk, thereby reducing I/O operations.
• They allow the database to quickly locate and access specific rows without scanning the entire table.

3. What is the difference between a primary key and a foreign key?

• A primary key is a unique identifier for a row in a table and ensures that each row has a distinct value.
• A foreign key is a field in a table that references a primary key in another table, establishing a relationship between the two tables.

4. What is the purpose of using a transaction in a database?

Data Consistency and Integrity

• Transactions ensure that a set of database operations is executed as a single unit, maintaining data integrity.
• They prevent data corruption by ensuring that either all operations in a transaction succeed or none of them do (Atomicity).

Isolation and Concurrency

• Transactions provide isolation, allowing multiple concurrent transactions to execute without interfering with each other.
• They ensure that each transaction sees a consistent view of the database, even if other transactions are modifying data concurrently.

Durability and Recovery

• Transactions guarantee durability by ensuring that committed changes are permanent, even in the event of a system failure.
• They provide a way to recover the database to a consistent state in case of crashes or errors.

5. What is the difference between a stored procedure and a user-defined function (UDF)?

Stored Procedure

• A stored procedure is a collection of SQL statements that are stored in the database and can be executed as a single unit.
• It is used to perform complex database operations and can be reused multiple times.

User-Defined Function (UDF)

• A UDF is a function that is defined by the user and can be used in SQL statements.
• It is used to extend the functionality of SQL and can be used to perform calculations, manipulate data, or return values.

6. What is the purpose of using a view in a database?

Data Abstraction

• Views provide a logical representation of data, hiding the underlying complexity of the database schema.
• They allow users to access data without being concerned about the physical structure of the tables.

Data Security

• Views can be used to restrict access to sensitive data by limiting the columns and rows that are visible to specific users.
• They provide a way to enforce data security policies and prevent unauthorized access.

Data Virtualization

• Views can be used to create virtual tables that combine data from multiple sources or perform calculations on the fly.
• They provide a way to present data in a customized and optimized manner, without requiring any changes to the underlying tables.

7. What is the difference between a trigger and a stored procedure?

Trigger

• A trigger is a database object that is automatically executed when a specific event occurs, such as inserting, updating, or deleting data in a table.
• Triggers are used to enforce business rules, maintain data integrity, or perform other automated actions.

Stored Procedure

• A stored procedure is a set of SQL statements that are stored in the database and can be executed as a single unit.
• Stored procedures are used to perform complex database operations and can be reused multiple times.

8. What is the purpose of using a cursor in a database?

Iterating Through Results

• Cursors allow you to iterate through the results of a query one row at a time.
• They are useful when you need to process data in a specific order or perform operations on individual rows.

Updating Data

• Cursors can also be used to update data in a database.
• You can use cursors to fetch a row, modify it, and then update the database with the changes.

9. What is the difference between a UNION and a UNION ALL operator?

UNION

• The UNION operator combines the results of two or more SELECT statements and removes duplicate rows.
• It is used to combine data from multiple sources while ensuring that each row appears only once in the result.

UNION ALL

• The UNION ALL operator combines the results of two or more SELECT statements and includes all rows, even if they are duplicates.
• It is used to combine data from multiple sources and preserve all rows, regardless of whether they are unique or not.

10. What is the purpose of using a database transaction log?

Data Recovery

• Transaction logs record all changes made to the database, allowing for data recovery in case of system failures or errors.
• They provide a way to roll back transactions and restore the database to a consistent state.

Concurrency Control

• Transaction logs help maintain data integrity in concurrent environments by tracking changes and ensuring that transactions do not interfere with each other.
• They prevent data corruption and ensure that each transaction sees a consistent view of the database.
