Millist tüüpi SQL-ühendus kasutatakse kõigi mõlemas tabelis olevate elementide väljavõtmiseks?

To extract all elements present in both tables, INNER JOIN is used. This type of join returns only the rows that have matching values in both tables according to the join condition.
Example SQL query:
SELECT *
FROM table1
INNER JOIN table2 ON table1.id = table2.id;
As a result, only those records where the id field values match in both tables will be obtained.
