Sergei Petrunia	0b15557c8f	MDEV-6796: Unable to skip filesort when using implicit extended key ... Re-work test_if_order_by_key() to work correctly for extended indexes.	2014-09-26 15:54:35 +04:00

Fix test_if_skip_sort_order() logic: WHEN we use index X, which doesn't produce needed ordering, but there is an index Y which does and has the same prefix as used prefix of X THEN don't just switch to using ref access on Y. If range(Y) would use more key parts, use range(Y).	2014-09-12 02:19:49 +04:00
