8 check-ins related to "insert-optimization"
2014-02-17
| ||
23:52 | Merge in performance enhancements for INSERT operations, especially INSERTs on tables that have no affinity columns or that have many indices or INSERTs with content coming from a SELECT. Add the SQLITE_TESTCTRL_VDBE_COVERAGE test control and the SQLITE_VDBE_COVERAGE compile-time option used for measure coverage of branches in VDBE programs. (check-in: a7268769 user: drh tags: trunk) | |
22:40 | Add logic to do test coverage measurements on the VDBE code. (Closed-Leaf check-in: ce184c7b user: drh tags: insert-optimization) | |
15:40 | Add a test case for OP_SoftNull. (check-in: f29d194e user: drh tags: insert-optimization) | |
15:36 | Merge the VDBE_PROFILE fixes from trunk. (check-in: 2914e419 user: drh tags: insert-optimization) | |
14:59 | Avoid unnecessary calls to applyAffinity() during INSERT and UPDATE operations, especially for table that have indices and tables for which all columns have affinity "NONE". (check-in: 35b4d6e9 user: drh tags: insert-optimization) | |
01:13 | Fix the VDBE_PROFILE logic. Add a script to process the output file. (check-in: 7adb3da2 user: drh tags: trunk) | |

01:55 | Enhance the code generator for INSERT INTO ... SELECT so that the SELECT generates output directly in the registers that INSERT INTO will be using, in many cases, and OP_SCopy operations can thus be avoided. (check-in: aa2d8b0e user: drh tags: insert-optimization) | |

23:49 | Seek past NULLs in a top-constrained search. Avoid checking for NULLs in the body of the search. (check-in: e07a32f3 user: drh tags: trunk) | |
