The following rules apply to the use of INTERSECT:

  • In addition to using INTERSECT within simple queries, you can use INTERSECT within the following operations:
    • Derived tables

      You cannot use the HASH BY or LOCAL ORDER BY clauses in derived tables with set operators.

    • Subqueries
    • INSERT ... SELECT statements
    • View definitions
  • Each query connected by INTERSECT is executed to produce a result consisting of a set of rows. The intersection must include the same number of columns from each table in each SELECT statement (more formally, they must be of the same degree), and the data types of these columns should be compatible.
  • INTERSECT cannot be used within the following:
    • SELECT AND CONSUME statements.
    • WITH RECURSIVE clause
    • CREATE RECURSIVE VIEW statements
