-------------------------------------------------------------------------
Key: DERBY-2238
URL: https://issues.apache.org/jira/browse/DERBY-2238
Project: Derby
Issue Type: Bug
Components: Documentation
Environment:
http://db.apache.org/derby/docs/dev/ref/rrefscalarsubquery.html
Reporter: Tomohito Nakayama
In the page, I found next example.
-- Introduce a way of "generating" new data values,
-- using a query which selects from a VALUES clause (which is an
-- alternate form of a fullselect).
-- This query shows how a table can be derived called "X" having
-- 2 columns "R1" and "R2" and 1 row of data.
SELECT R1,R2
FROM (VALUES('GROUP 1','GROUP 2')) AS X(R1,R2)
I think this is not ScalarSubquery because the result have two columns.
