DBA DEVELOPER Interview questions on sql joins MSSQL
In SQL Server, joins combine rows from two or more tables based on related columns. The main types are INNER JOIN (returns matched rows from both tables), LEFT JOIN (returns all rows from the left table and matched rows from the right), RIGHT JOIN (returns all rows from the right table and matched rows from the left), and FULL OUTER JOIN (returns all rows when there's a match in either table). Each type serves different data retrieval needs in relational databases.
