Hmmm ...
Better make that
Keyword | Standard | Status |
------------+-----------+---------+
SELECT | SQL92 | Reserved|
SELECT | SQL99 | Reserved|
SELECT | PostgreSQL| Reserved|
WITH | SQL92 | Nope |
WITH | SQL99 | Reserved|
WITH | PostgeSQL | Nope |
IN | SQL92 | Nope |
IN | SQL99 | Reserved|
IN | PostgreSQL| Yep |
This form allows for greater flexibility in query/views building. Obvious
drawback : the primary key is composite.
Any thoughts ?
