Move some things in parse.y so that TK_COLUMN and TK_AGG_COLUMN are assigned the same values as they are on trunk for a very small speedup. check-in: d26fdfa3 user: dan tags: nulls-last
17:09
Revise the VDBE comments for NULL-scan so that they also work make sense when reading a NULLS FIRST plan. check-in: bfe79378 user: drh tags: nulls-last
17:00
Additional simplifications of the WHERE loop code generator logic for NULLS LAST. check-in: 1383680d user: drh tags: nulls-last
16:12
Simplification of the WHERE loop code generator for NULLS LAST saves a few CPU cycles and about a hundred bytes of code space. check-in: e3ed2f49 user: drh tags: nulls-last
13:32
Invert the meaning of the regBignull flag so that it is 1 when doing the normal scan and 1 when scanning nulls. This enables the re-do jump at the bottom of the loop to be coded with a single OP_IfNotZero opcode, rather than a sequence of OP_If, OP_Integer, OP_Goto. check-in: bf875e1a user: drh tags: nulls-last
13:08
Extra VDBE comments in the NULLS LAST logic provide landmarks to help understand the EXPLAIN output. check-in: 649b08ea user: drh tags: nulls-last

Merge fixes from trunk. Also fix a reference to the KeyInfo.aSortOrder field, which should now be KeyInfo.aSortFlags check-in: 63e625c8 user: drh tags: nulls-last

19:58
Add missing VdbeCoverage() macros to new code. check-in: b1cbcdc6 user: dan tags: nulls-last

Disable broken test case in expert1.test. check-in: 73e30c2e user: dan tags: nulls-last

Further tests for the special null-handling on this branch. check-in: 0dbbb51f user: dan tags: nulls-last
17:51
Add tests for sort-by-index cases that use IN() and non-default NULL handling. check-in: 09d660ec user: dan tags: nulls-last
15:47
Do not pass ORDER BY clauses with non-standard NULL handling to virtual table implementations. check-in: a9a82ee8 user: dan tags: nulls-last

Fix problems with window frames that use ORDER BY ... NULLS LAST etc. check-in: 75d665a4 user: dan tags: nulls-last

Prevent NULLS FIRST/LAST from being used in CREATE INDEX and other statements. check-in: bb9767a2 user: dan tags: nulls-last
2019-08-17

Add tests to ensure that this branch really does fix ticket [f8a7060ece]. check-in: f8920664 user: dan tags: nulls-last
17:55
Fix problem with DESC indexes on this branch. check-in: b49df1fe user: dan tags: nulls-last

Merge trunk changes into this branch. check-in: db1e6080 user: dan tags: nulls-last
2019-08-16
21:07
Add support for using indexes for some ORDER BY clauses that use non-default NULL handling. Still some problems on this branch. check-in: 81069d71 user: dan tags: nulls-last
2019-08-12
16:36
Experimental implementation of NULLS FIRST/LAST. This branch still has problems - the most significant of which is that ORDER BY clauses with a non-default NULLS FIRST/LAST qualifier can never use an index. check-in: 07babb0f user: dan tags: nulls-last
