b) INTERSECT
c) EXCEPT
d) MINUS

Answer 1

The EXCEPT set operator is used to display results unique to the first query and not found in the second. It filters out common data between two query results, returning distinct values from the first query.

Step-by-step explanation:

The set operator used to display the results that werebcompares the results of two queries and returns any distinct values from the first query that are not also found in the second query. If the same data is featured in both queries, it will not appear in the final result set returned by the EXCEPT operation. Understanding how the EXCEPT operator functions is essential for effectively managing and analyzing data sets in SQL.
