[Tarantool-patches] [PATCH 4/5] sql: replace control pragmas by SET

Wed Nov 27 13:13:33 MSK 2019


This patch replaces the control pragmas with SET. List of replaced
control pragmas and their SET settings:
	Control pragmas			SET parameters
defer_foreign_keys		sql_defer_foreign_keys
full_column_names		sql_full_column_names
recursive_triggers		sql_recursive_triggers
reverse_unordered_selects	sql_reverse_unordered_selects
sql_compound_select_limit	sql_compound_select_limit
sql_default_engine		sql_default_engine

Also, in debug build, these control pragmas are replaced by SET
settings:
	Control pragmas			SET parameters
parser_trace			sql_parser_trace
select_trace			sql_select_trace
sql_trace			sql_trace
vdbe_addoptrace			sql_vdbe_addoptrace
vdbe_debug			sql_vdbe_debug
vdbe_eqp			sql_vdbe_eqp
vdbe_listing			sql_vdbe_listing
vdbe_trace			sql_vdbe_trace
where_trace			sql_where_trace

Difference between SET and control pragma:
1) SET have more definite syntax:
SET <setting name> = <setting value>;
In PRAGMA, we could set the settings using these methods:
PRAGMA <setting name> = <setting value>;
PRAGMA <setting name>(<setting value>);

2) SET allows only a specific type of value for each setting. In
PRAGMA, we could use almost everything to set up any setting.
Although the rules by which the settings were set in PRAGMA were
pretty easy to understand.

3) SET cannot display setting values. PRAGMA showed the setting
values using the syntax "PRAGMA <setting name>;". With SET, we
must use other means to get the current setting values. For
session settings, we could use the sysview "_vsession_settings"
to get these values. It is worth noting that all current SQL
settings are session settings, with the exception of
'sql_reverse_unordered_selects'.

After this patch there will be no control pragmas.

Closes #4511
Closes #4621

@TarantoolBot document
Title: SQL SET statement

SQL SET statement is used to change SQL settings. To change the
value of an SQL setting, use the following syntax:

SET <setting name> = <setting value>;

Currently available SQL settings:
'sql_defer_foreign_keys'
'sql_full_column_names'
'sql_recursive_triggers'
'sql_reverse_unordered_selects'
'sql_compound_select_limit'
'sql_default_engine'

In addition, SQL debugging settings can also be changed using this
statement in debug build:
'sql_parser_trace'
'sql_select_trace'
'sql_trace'
'sql_vdbe_addoptrace'
'sql_vdbe_debug'
'sql_vdbe_eqp'
'sql_vdbe_listing'
'sql_vdbe_trace'
'sql_where_trace'

Example of usage:
SET sql_full_column_names = true;
SET sql_compound_select_limit = 10;
SET sql_default_engine = 'memtx';
