-------------------------------------------
Summary: Tabular view FOREIGN KEY clause is name-deficient
Key: ASTERIXDB-3317
URL: https://issues.apache.org/jira/browse/ASTERIXDB-3317
Project: Apache AsterixDB
Issue Type: Improvement
Components: COMP - Compiler, SQL - Translator SQL++
Affects Versions: 0.9.9
Reporter: Michael J. Carey
Assignee: Peeyush Gupta
Fix For: 0.9.9
Right now the FOREIGN KEY clause for tabular views is badly deficient.
Its REFERENCES target must just be the name of a targeted tabular view.
Like SQL, this needs to be a targeted tabular view with a parenthetical field
name list so that one's foreign fields can be differently named than the
targeted primary key fields.
For example:
... FOREIGN KEY (orderno, itemno) REFERENCES items_view NOT ENFORCED
versus
... FOREIGN KEY (orderno, itemno) REFERENCES items_view (ono, ino) NOT ENFORCED
The former requires name matching while the latter, like SQL, allows the names
to be different.
