Subject: [tarantool-patches] [PATCH 1/5] sql: prohibit creation of FK on unexisting tables
Date: Fri, 13 Jul 2018 05:04:17 +0300	[thread overview]
Message-ID: <32f36b207de86bf144b16260c9ed434b45cf094c.1531443603.git.korablev@tarantool.org> (raw)
In-Reply-To: <cover.1531443603.git.korablev@tarantool.org>
In-Reply-To: <cover.1531443603.git.korablev@tarantool.org>

Originally, SQLite allows to create table with foreign keys contraint
which refers to yet not created parent table. For instance:

CREATE TABLE child(id INT PRIMARY KEY REFERENCES parent);
CREATE TABLE parent(id INT PRIMARY KEY);

This patch bans such ability since it contradicts SQL ANSI.
Moreover, SQLite allows to drop parent table if deletion of all rows
wouldn't result in FK contraint violations. This feature has been
removed since in such situation child table would become inconsistent.

Finally, within current patch ability to create FK contraints on VIEWs
is banned as well.

Part of #3271
