Subject: Re: [Tarantool-patches] [PATCH v5 42/52] sql: introduce mem_to_str() and mem_to_str0()
Date: Wed, 14 Apr 2021 02:41:42 +0300	[thread overview]
Message-ID: <20210413234142.GA101298@tarantool.org> (raw)
In-Reply-To: <afd5f3dd-9311-dae4-2631-64680bd1c6a7@tarantool.org>

Thank you for the review! My answer, diff and new patch below. Also, I moved
<type>_to_<type>() functions to group them.

New patch:


commit 46a840d827f10f69cfcd7fd0075aa09ddd27ccc8
Author: Mergen Imeev <imeevma@gmail.com>
Date:   Wed Mar 17 11:55:48 2021 +0300

    sql: introduce mem_to_str() and mem_to_str0()
    
    This patch introduces mem_to_str() and mem_to_str0() functions. These
    functions are used to convert a MEM to a MEM that contains string value.
    These functions defines the rules that are used during convertion from
    values of all other types to STRING.
    
    Part of #5818
