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.
Other table operators:
Except: except [distinct]
, except all
Union: union [distinct]
, union all
The intersect all
operator is defined in ISO/IEC 9075-2 as the optional feature F302-02, “INTERSECT ALL table operator”.
