    Different types of joins in SQL include inner join, left join, right join, and full outer join.

    • Inner join: Returns rows when there is a match in both tables.

    • Left join: Returns all rows from the left table and the matched rows from the right table.

    • Right join: Returns all rows from the right table and the matched rows from the left table.

    • Full outer join: Returns rows when there is a match in either table.

  • Answered by AI
  • Q2. What is the difference between a Union and an Outer join, and can you provide the syntax for both using two simple tables?
  • Ans. 

    Union combines results from two tables, while Outer join combines matching rows and includes non-matching rows.

    • Union combines all rows from both tables, removing duplicates

    • Outer join combines matching rows and includes non-matching rows with NULL values

    • Syntax for Union: SELECT * FROM table1 UNION SELECT * FROM table2

    • Syntax for Outer join: SELECT * FROM table1 LEFT OUTER JOIN table2 ON table1.id = table2.id

    • Remove duplicates from the sorted list

    • Repeat the process for both Blinkit and Zepto campaigns

Interview Preparation Tips

Interview preparation tips for other job seekers - Be prepared in Excel, SQL, and Python. The data provided may be unclear, so it is crucial to have a solid understanding of the core concepts, focusing primarily on Excel and SQL. The interviewer may not respond kindly if you don't answer their questions or if you seek clarification regarding the data or the questions posed. This behavior does not reflect professionalism. If anyone from 1DigitalStack comes across this, I kindly request that you provide training for your interviewers on maintaining professional conduct.
