Subject: [tarantool-patches] [PATCH 4/6] sql: enforce implicit type conversions
Date: Mon, 17 Sep 2018 23:32:28 +0300	[thread overview]
Message-ID: <d060ef561a49722c55bff0ead926f9642df98e54.1537216078.git.korablev@tarantool.org> (raw)
In-Reply-To: <cover.1537216077.git.korablev@tarantool.org>
In-Reply-To: <cover.1537216077.git.korablev@tarantool.org>

From: Georgy Kirichenko <georgy@tarantool.org>

Most DBs (at least PostgreSQL, Oracle and DB2) allow to process
following queries:

CREATE TABLE t1 (id INT PRIMARY KEY);
INSERT INTO t1 VALUES (1.123), ('2');

In this particular case, 1.123 should be simply truncated to 1,
and '2' - converted to literal number 2.

After passing real type to Tarantool (instead of <SCALAR>), example
above would fail without conversions. Thus, lets add implicit
conversions inside VDBE to make this example be legal.
However, still some types conversions must be prohibited. For instance,
<BLOB> can't be converted to integer or floating point numerical,
and vice versa.
