8 check-ins using file src/expr.c version e5f0cf64
|20:33||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|
|21:13||Add additional VDBE coverage macros. check-in: d3531f5b user: drh tags: nulls-last|
|19:35||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|
