Eloy Lafuente (stronk7)	c9840c0144	MDL-62619 privacy: Prevent action when boolean queries are involved ... Before the patch, queries like: SELECT 1 FROM dual UNION SELECT 2 FROM dual were failing badly, with everything but the first numeric element being ignored by the optimization. So, being conservative, now we reduce the query being analysed, ignoring any subquery, inline view (anything within parenthesis in general) and, in the remaining query, if a boolean query (UNION, MINUS, INTERSECT...) is found, we don't apply any optimization.	2018-08-09 16:05:55 +02:00
David Mudrák	cea03cbd43	MDL-62619 privacy: Fix some bits of performance improvements ... * We need to use is_numeric() in this case as is_int() would never return true. * Extend the supported cases, add support for SQL consisting just of numerical value or selectinga numerical constant. * Do not rely on any particulat letter case in provided SQL. * Add unit tests for the new method. Even when it is a protected one, it is an essential unit to be tested on its own.	2018-07-27 10:14:43 +02:00
