Rick Hillegas created DERBY-5779:
------------------------------------
Summary: Table functions and vtis should only accept arguments which are constant
in their query block.
Key: DERBY-5779
URL: https://issues.apache.org/jira/browse/DERBY-5779
Project: Derby
Issue Type: Bug
Components: SQL
Affects Versions: 10.9.0.0
Reporter: Rick Hillegas
Derby lets you invoke a table function/vti in the FROM list of a query, passing in arguments
built out of columns in other tables in the FROM list. This syntax is illegal and the resulting
queries have no meaning under the SQL Standard. See the discussion on DERBY-5554. We should
forbid this syntax. Similar syntax involving correlated subqueries in the FROM list is already
forbidden. Fixing this will create a backward incompatibility which requires a release note.
In particular, the sample usage for SYSCS_DIAG.SPACE_TABLE, given in the Reference Manual,
will no longer work after fixing this bug. Changes to SPACE_TABLE are being discussed on DERBY-5554.
