Galina Shalygina	46a2e41398	Fixed many problems in the code of With_element::check_unrestricted_recursive(). ... Added the check whether there are set functions in the specifications of recursive CTE. Added the check whether there are recursive references in subqueries. Introduced boolean system variable 'standards_compliant_cte'. By default it's set to 'on'. When it's set to 'off' non-standard compliant CTE can be executed.	2016-05-19 22:07:53 +03:00
