Describe Join Concepts (SQL).

Question

Accepted Answer

Join concepts in SQL are used to combine rows from two or more tables based on a related column between them.

Joins are used to retrieve data from multiple tables in a single query.
Types of joins include INNER JOIN, LEFT JOIN, RIGHT JOIN, and FULL JOIN.
INNER JOIN returns rows when there is at least one 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 JOIN returns rows when there is a match in one of the tables.
Example: SELECT * FROM table1 INNER JOIN table2 ON table1.column = table2.column;
