30-DAYS-SQL-QUESTION-SERIES

I have recently started my SQL Journey a few months back. While I was learning SQL, I learned many new things, starting from what are the DDLs, and DMLs to solving complex queries. After I started getting hands-on experience in writing SQL queries, I started posting SQL Problems on LinkedIn with the solutions.

The only thing I have followed till now is consistency and eagerness to solve SQL queries. Each skill has its own difficulty level so does SQL.

• EASY
• MEDIUM
• HARD

In this repository, I will share all the questions that I posted on LinkedIn as a 30-Day SQL Question Series with their datasets, questions, and solutions. All these 30 Questions are likely to be asked during the interview( or mock interviews) ranging from EASY to DIFFICULT.

DATA SOURCE

I have listed all the following sources below from where I have taken the questions:

1. DATALEMUR Website(SQL Qestions)
2. Dany Diner's Case Study for SQL
3. Employee dataset
4. HackeRank SQL Quetions
5. Leetcode

I have tried to cover almost all the necessary functions and keywords in this repository.

To master SQL, one should practice SQL consistently.

I hope that you appreciate this repository as much as you appreciate the 30-Day SQL Question Series.
