Subject: [Tarantool-patches] [PATCH 10/15] sql: add sql_schema_version()
Date: Thu,  7 Nov 2019 04:04:50 +0300	[thread overview]
Message-ID: <20191107010455.64457-11-korablev@tarantool.org> (raw)
In-Reply-To: <20191107010455.64457-1-korablev@tarantool.org>

Let's introduce interface function to get schema version of prepared
statement. It is required since sturct sql_stmt (i.e. prepared
statement) is an opaque object and in fact is an alias to struct Vdbe.

Need for #2592
