drh	31daa63f3e	Disable the result-set alias cache when on conditional code branches. Ticket #3461. The column cache and result set alias cache mechanisms are prone to this kind of error and need to be refactored. This check-in should be considered a temporary fix in advance of a more general redesign of the whole mechanism.

drh	8b213899e8	Avoid reevaluating WHERE and ORDER BY expressions that alias terms in the result set. Ticket #3343. Note that aliased GROUP BY expressions are still evaluated twice. (CVS 5637) FossilOrigin-Name: ab0292caa5887cc1bdc0e8c9d3f3502b83975440	2008-08-29 02:14:02 +00:00
