Can you name the main types of relationships between tables in SQL?

Main types of relationships between tables in SQL:

• INNER JOIN — returns only the records that match the condition 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 are shown on the right side.
• RIGHT JOIN (RIGHT OUTER JOIN) — the opposite, returns all records from the right table and matching records from the left.
• FULL JOIN (FULL OUTER JOIN) — returns all records from both tables; where there are no matches, NULLs are shown in the respective fields.

These relationships allow combining data from multiple tables based on specific keys to obtain comprehensive information.
