15:24 | Virtual tables now always report 25 rows instead of 0 rows in the EXPLAIN QUERY PLAN output. Adjust tests accordingly. (check-in: 7d91f68881 user: drh tags: nextgen-query-plan-exp) | |

20:43 | The NGQP might not find a solution if INDEXED BY constraints on the query are set wrong. If that is the case, print a "no query solution" error and abort before trying to use the non-existant solution. (check-in: 42511a7e12 user: drh tags: nextgen-query-plan-exp) | |
20:28 | Do not search using ON clause constraints of LEFT JOINs to the right of the table. (check-in: 723f901a63 user: drh tags: nextgen-query-plan-exp) | |
20:00 | Make sure a unique cursor number is allocated for automatic indices. (check-in: 433d1aecd3 user: drh tags: nextgen-query-plan-exp) | |
19:14 | Do not attempt to generate code in the NGQP if there have been prior errors, since with prior errors some of the expressions might not be fully named resolved. (check-in: 665e4291c6 user: drh tags: nextgen-query-plan-exp) | |
18:20 | Fix a problem with code generation on LEFT JOIN of tables without an index. (check-in: 0b1bee92a0 user: drh tags: nextgen-query-plan-exp) | |
18:13 | Another virtual table fix in NGQP. (check-in: 2f2ce41677 user: drh tags: nextgen-query-plan-exp) | |
17:55 | Fix problems in the virtual table logic for NGQP. (check-in: 23af28e24b user: drh tags: nextgen-query-plan-exp) | |
15:50 | Remove the definitions of objects that are no longer used: WhereCost, WherePlan, and WhereBestIdx. (check-in: 816f8add7e user: drh tags: nextgen-query-plan-exp) | |
15:18 | Allow tracing of whereLoopInsert() when the 0x8 bit is set on ".wheretrace". Remove the use of sqlite_query_plan from where2.test. Fix a bug in the code generator for OR clause optimizations. (check-in: 707f032326 user: drh tags: nextgen-query-plan-exp) | |
14:31 | Enhance the shell to provide more flexibility when entering numeric arguments on dot-commands. In particular, allow hex arguments to .wheretrace. (check-in: b9578c371e user: drh tags: nextgen-query-plan-exp) | |
13:36 | Futher enhancements to the ORDER BY optimizer. (check-in: d8efa5f8b6 user: drh tags: nextgen-query-plan-exp) | |

23:21 | Improvements to the ORDER BY suppressor in the NGQP. (check-in: 24a2e9ddce user: drh tags: nextgen-query-plan-exp) | |
22:27 | Incremental check-in with various NGQP fixes. Many tests still fail. (check-in: a51d8c9249 user: drh tags: nextgen-query-plan-exp) | |
19:29 | Futher simplifications to the NGQP. Fix some test cases to use EXPLAIN QUERY PLAN rather than the (now obsolete) sqlite_query_plan global variable. (check-in: ae985db4fa user: drh tags: nextgen-query-plan-exp) | |
19:28 | The expected result in a test case can be of the form "*glob*" or "~*glob*" to match or not match the GLOB pattern. This is useful for matching EXPLAIN QUERY PLAN output that contains regular expression syntax characters like "?", "(", and ")". (check-in: a3b4e261bd user: drh tags: nextgen-query-plan-exp) | |
17:43 | Cut over the NGQP query planner. Remove lots of legacy code. This check-in compiles but does not work. The test suite gets incorrect answers and crashes. (check-in: 001539df4b user: drh tags: nextgen-query-plan-exp) | |

20:49 | Use the NGQP plan for EXPLAIN QUERY PLAN output. This change causes 207 errors in veryquick.test, many of which are benign. (check-in: f783e8e6b1 user: drh tags: nextgen-query-plan-exp) | |
17:01 | Allow the rowid at the end of an index to be used in a constraint on that index. (check-in: 9bf0524df7 user: drh tags: nextgen-query-plan-exp) | |
02:06 | Improvements to ORDER BY handling in the NGQP. Fix an "exit" mistakenly left in a test script during the previous check-in. (check-in: 12c709b436 user: drh tags: nextgen-query-plan-exp) | |
2013-05-21

20:05 | Fix memory leaks in the NGQP logic for virtual tables. (check-in: 3c2e83a4a2 user: drh tags: nextgen-query-plan-exp) | |
14:14 | NGQP working with virtual tables, though many legacy tests fail and there are yet some memory leaks. (check-in: bd9327a968 user: drh tags: nextgen-query-plan-exp) | |
14:13 | Fix the wholenumber virtual table so that it returns higher costs for unconstrained usage. (check-in: ceff895502 user: drh tags: nextgen-query-plan-exp) | |
04:22 | More bug fixes to the WhereLoop generator and the solver in NGQP. Now finds the best plan for TPC-H Q8. This seems to prove the concept, but there is still much work to be done. (check-in: 8e5aad3752 user: drh tags: nextgen-query-plan-exp) | |
03:22 | Bug fixes in the solver. (check-in: b36034bbd1 user: drh tags: nextgen-query-plan-exp) | |

2013-05-04
| ||
20:25 | In where.c, make findTerm() a wrapper around methods to a new WhereScan object which is capable of finding all suitable matching terms, not just the first.
