Explain about joins?

Question

Accepted Answer

Joins are used in databases 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.
Common types of joins include inner join, left join, right join, and full outer join.
Inner join returns only the matching rows between the tables.
Left join returns all rows from the left table and the matching rows from the right table.
Right join returns all rows from the right table and the matching rows from the left table.
Full outer join returns all rows from both tables, including unmatched rows.
Join conditions are specified using the ON keyword and the related columns.
Example: SELECT * FROM table1 INNER JOIN table2 ON table1.column = table2.column;
