SQL INTERSECT

SQL INTERSECT allows combining results of two or more select queries. If a record exists in one query and not in the other, it will be omitted from the INTERSECT results.

Syntax:Select field1, field2, . field_n from tables INTERSECT select field1, field2, . field_n from tables;

Example:Select salary from employee INTERSECT select salary from manager;
