| 15:27 | Evaluate WHERE clause terms that reference only the index before evaluating terms that require the table, and thereby avoid seeking the table row if index terms are false.

| 14:56 | Minor size and performance improvements to the push-down optimization. (Closed-Leaf check-in: 91dfb61a1a user: drh tags: pushdown-optimization) | |

| 14:16 | When building an ephemeral table of integers, do not assume that the table does not already contain N if the insert cursor points to N-1. Fix for ticket [61fe9745]. (check-in: 1c1b086223 user: dan tags: trunk) | |

|
2017-04-18
| ||
| 13:50 | Use sqlite3_table_column_metadata() instead of a SELECT statement to check for the existence of a %_stat table in fts3. This leads to smaller and easier to test code. (check-in: dc2a48020a user: dan tags: trunk) | |
| 11:20 | Improved optimizations of views as the right operand of a LEFT JOIN. (check-in: 41c27bc0ff user: drh tags: trunk) | |
| 05:49 | Refactor the fts3ColumnMethod() function so that all branches can be covered. (check-in: e47fdb493b user: dan tags: trunk) | |

| 18:02 | Fix a problem in "PRAGMA foreign_key_check" in handling a WITHOUT ROWID child table with an INTEGER PRIMARY KEY parent key. Also, if an FK violation is detected in a WITHOUT ROWID child table, do not try to read and return the rowid. The second column returned by "PRAGMA foreign_key_check" in this case (WITHOUT ROWID child table) is now always set to NULL. (check-in: 690870bd7b user: dan tags: trunk) | |
| 16:07 | Further improvements to test coverage in fts3. (check-in: 352413eed4 user: dan tags: trunk) | |

|
2017-04-16
| ||
| 22:41 | In the showwal command-line tool, for unix builds, if the auxiliary argument is of the form "Ntruncate" where "N" is a frame number, then truncate the WAL file after the N-th frame. (check-in: 90015df306 user: drh tags: trunk) | |

| 19:03 | Add the TK_IF_NULL_ROW opcode to deal with non-NULL result columns in the result set of a view or subquery on the RHS of a LEFT JOIN that gets flattened. (Closed-Leaf check-in: 3a5860d86f user: drh tags: left-join-view) | |
