2015-06-08
22:59
Code refactoring to try to shift FROM-clause subquery manifesting until after the query planner runs.

Add the valgrindfuzz target to unix makefile. check-in: e62aed01 user: drh tags: trunk

01:35
Using "SELECT ALL" instead of just "SELECT" on a query that uses a single unflattenable subquery or view in its FROM clause will force the subquery to be manifested into a temporary table rather than run incrementally using a co-routine. This is a stop-gap means of controlling the decision to manifest while we try to work out a better to make that decision automatically. check-in: a29e117d user: drh tags: trunk
2015-05-28
19:57

14:21
