Can you list the main types of table joins in SQL and briefly describe their features?

Main types of JOINs in SQL:

• INNER JOIN — returns only those records that have matches in both tables.
• LEFT JOIN (LEFT OUTER JOIN) — returns all records from the left table and matching records from the right; if there are no matches, NULLs will appear on the right side.
• RIGHT JOIN (RIGHT OUTER JOIN) — conversely, returns all records from the right table and matching records from the left.
• FULL JOIN (FULL OUTER JOIN) — returns all records from both tables, with NULLs in the fields where there are no matches.
• CROSS JOIN — Cartesian product of two tables, returning all possible combinations of rows.

Example of INNER JOIN:

SELECT Orders.OrderID, Customers.CustomerName
FROM Orders
INNER JOIN Customers ON Orders.CustomerID = Customers.CustomerID;
