Subject: [Tarantool-patches] [PATCH v1 2/5] box: introduce _vsql_settings sysview
Date: Thu, 17 Oct 2019 17:40:15 +0300	[thread overview]
Message-ID: <6a36d22fd2083d5ab415947ec46ee5708e89337f.1571322776.git.imeevma@gmail.com> (raw)
In-Reply-To: <cover.1571322776.git.imeevma@gmail.com>

This patch creates the _vsql_settings sysview. This system view
has custom methods get() and create_iterator(). This allows us
to get SQL settings by creating a tuple on the fly without having
to save it anywhere.

Part of #4511

@TarantoolBot document
Title: The _vsql_settings sysview
Sysview _vsql_settings allows the user to get the current SQL
parameters.

Currently available SQL settings:
'defer_foreign_keys'
'full_column_names'
'recursive_triggers'
'reverse_unordered_selects'
'sql_compound_select_limit'
'sql_default_engine'

In addition, SQL debugging settings can also be obtained from this
system view in the debug build:
'parser_trace'
'select_trace'
'sql_trace'
'vdbe_addoptrace'
'vdbe_debug'
'vdbe_eqp'
'vdbe_listing'
'vdbe_trace'
'where_trace'

Example of usage:
box.space._vsql_settings:get{'full_column_names'}
box.space._vsql_settings:select{'defer_foreign_keys'}
box.space._vsql_settings:select{'full_column_names', {iterator = 'LE'}}
