What is the main difference between a LEFT JOIN and a RIGHT JOIN in SQL?

  • LEFT JOIN returns unmatched rows from the left table, RIGHT JOIN from the right table
  • LEFT JOIN returns all rows from both tables, RIGHT JOIN only matching rows
  • LEFT JOIN and RIGHT JOIN are the same, just synonyms for the same operation
  • LEFT JOIN is used for numeric data, RIGHT JOIN for text data
The main difference between a LEFT JOIN and a RIGHT JOIN in SQL is that a LEFT JOIN returns all the rows from the left table and the matched rows from the right table, including unmatched rows from the left. In contrast, a RIGHT JOIN returns all the rows from the right table and the matched rows from the left table, including unmatched rows from the right.
