INTERSECT ALL (table operator)

The table operator intersect all returns the rows that are present in both results.

SELECT …
  FROM …
INTERSECT ALL
SELECT …
  FROM …

As with all table operators both sides of intersect must have the same number of columns and their types must be compatible based on their position (see corresponding). All null values are considered being the same (not distinct) for this operation.
