Question
The SQL JOIN clause is used to combine records from two or more tables in a database. A FULL JOIN returns only the set of all records in both tables which do not have matching values. TrueFalse
Solution
False. The statement is incorrect. A FULL JOIN in SQL returns all the records when there is a match in either the left (table1) or the right (table2) table records. Essentially, it combines the results of both LEFT and RIGHT joins. The statement would be correct if it was referring to a FULL OUTER JOIN, which returns all records when there is a match in either left (table1) or the right (table2) table records, and NULL where there is no match.
