Subject [jira] [Commented] (DERBY-2238) Example of ScalarSubquery in Derby Reference Manual is not ScalarSubquery
Date Tue, 13 Jan 2015 14:24:35 GMT

    [ https://issues.apache.org/jira/browse/DERBY-2238?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14275237#comment-14275237

Kim Haase commented on DERBY-2238:

Thanks -- this is a good, simple way of fixing the problem. A VALUES expression is equivalent
to a query -- this is stated in the documentation of both the VALUES expression and a query
-- so it's a perfectly valid example. Looks like the commit has already shown up in the latest
alpha manuals, so the issue can be both resolved and closed.

> 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.
> I think this is not ScalarSubquery because the result have two columns.
