Fix sqlite3_analyzer so that it works with WITHOUT ROWID tables. Fix index generation for secondary indices that include fields from the PRIMARY KEY. check-in: f9769d70 user: drh tags: omit-rowid
18:14
Additional UPDATE test cases for WITHOUT ROWID. check-in: 65384ae0 user: drh tags: omit-rowid

Fix an invalid cast operation in the WITHOUT ROWID parsing logic. check-in: 845153be user: drh tags: omit-rowid
17:21
Merge all changes from trunk, and disable a pair of corruption tests that are no longer valid since sqlite_master.rootpage can now be NULL for tables. check-in: dd5d57b9 user: drh tags: omit-rowid
17:08
Change the interface to sqlite3GenerateConstraintChecks() for improved lucidity and to fix issues in dealing with UPDATEs for WITHOUT ROWID tables. Make sure iDataCur and iIdxCur are initialized when processing DELETEs of a VIEW. UPDATE processing distinguishes between changes to ROWID and PRIMARY KEY. check-in: c525ac56 user: drh tags: omit-rowid
14:03
Improved VDBE comments on the constraint checker. Fix a missing write lock in the UPDATE logic. check-in: 3bed599e user: drh tags: omit-rowid
12:42
Some UPDATE statements now working in WITHOUT ROWID tables. check-in: 5c0eaea6 user: drh tags: omit-rowid

A couple of bug fixes. check-in: cdf00248 user: drh tags: omit-rowid
2013-10-31
20:34
Fix the Synopsis on OP_Concat. Added test_addop_breakpoint() during SQLITE_DEBUG. Enhanced sqlite3VdbeChangeToNoop() to omit the instruction if it is the most recent added. Continue to fix problems with UPDATE and WITHOUT ROWID. check-in: 9b6d9e10 user: drh tags: omit-rowid
17:38
Fix issues with quering from an auxiliary index that must refer back to the PRIMARY KEY index of a WITHOUT ROWID table. check-in: cff1f55c user: drh tags: omit-rowid
15:37
Improved comments and variable names in infrastructure routines of UPDATE, DELETE, and INSERT. check-in: ad90e762 user: drh tags: omit-rowid
12:13
Moving UPDATE towards the iDataCur/iIdxCur representation. Still not working for WITHOUT ROWID, though. check-in: deacbd21 user: drh tags: omit-rowid
11:15
Refactor the INSERT, DELETE, and UPDATE code generators to distinguish between the "data cursor" and the "first index cursor", which are no longer consecutive in the case of a WITHOUT ROWID table. check-in: 1adfca60 user: drh tags: omit-rowid
2013-10-30
20:22
Continue working to get UPDATE operational for WITHOUT ROWID tables. Fix PRAGMA integrity_check so that it works on WITHOUT ROWID tables. check-in: 0d4fea74 user: drh tags: omit-rowid
15:52
Make sure KeyInfo objects on multi-column indices of WITHOUT ROWID tables have the correct nField and nXField values. Also, add the SQLITE_ENABLE_MODULE_COMMENT compile-time option and the VdbeModuleComment() macro and use it to label entry and exit points of some key routines. check-in: 6d9af606 user: drh tags: omit-rowid
13:46
In the P4 column of the EXPLAIN listing, abbreviate "keyinfo" as just "k" and "BINARY" as just "B". check-in: 72d45eb7 user: drh tags: omit-rowid
02:37
Merge EXPLAIN enhancements from trunk. check-in: 2fcac056 user: drh tags: omit-rowid

Import the automatic comment generating changes from trunk. check-in: 8bb51da1 user: drh tags: omit-rowid
16:14
Improved comments on the constraint checking logic. check-in: 141a38a7 user: drh tags: omit-rowid
2013-10-28
22:39
Merge recent fixes from trunk. check-in: 9f8191d1 user: drh tags: omit-rowid
2013-10-26
15:40
Work on the UPDATE and INSERT logic. This is an incremental check-in so that can switch over to trunk to work on an unrelated issue there. check-in: 086ec2a1 user: drh tags: omit-rowid
13:36
Replace the OP_IsUnique opcode with OP_NoConflict. This code simplification might be useful to move onto trunk even if this branch is never merged. check-in: e6650e16 user: drh tags: omit-rowid
00:58
Minor refactoring of variable names and fixes to comments in insert.c. check-in: ae61a343 user: drh tags: omit-rowid
2013-10-25
19:17
Progress toward getting UPDATE to work in WITHOUT ROWID tables. check-in: e557b7d8 user: drh tags: omit-rowid
14:46
Basic DELETE operations now working on WITHOUT ROWID tables. check-in: 9eafafa3 user: drh tags: omit-rowid
2013-10-24
19:48
Update the interface to the sqlite3GenerateRowDelete() utility so that it is able to handle WITHOUT ROWID tables. The implementation still needs to be completed. check-in: 85daf517 user: drh tags: omit-rowid
14:16
Delete PRIMARY KEY index entries last. Only construct the unique prefix of an index key when deleting entries from an index. check-in: 0e56ba69 user: drh tags: omit-rowid
11:55
Remove an obsolete comment from the VDBE. No code changes. check-in: 53bb070c user: drh tags: omit-rowid
00:18
Correctly handle queries that use secondary indices of WITHOUT ROWID tables. check-in: d8bc8595 user: drh tags: omit-rowid
2013-10-23
23:37
Change the sqlite3OpenTable() utility to open the PRIMARY KEY index when reading a WITHOUT ROWID table. check-in: 247f3899 user: drh tags: omit-rowid
22:23
Construct secondary indices on WITHOUT ROWID tables. check-in: 2c028ddc user: drh tags: omit-rowid
17:39
Report an error when trying to resolve column name "rowid" in a WITHOUT ROWID table. check-in: 36bcc9cb user: drh tags: omit-rowid
16:03
Get VACUUM and the xfer optimization working with WITHOUT ROWID. check-in: 579815ff user: drh tags: omit-rowid
13:30
Some inserts and queries working for multi-column primary keys and WITHOUT ROWID. check-in: b21d831b user: drh tags: omit-rowid
01:57
Some simple inserts and queries working on WITHOUT ROWID tables. check-in: 3f8016de user: drh tags: omit-rowid

Build internal data structures appropriately for WITHOUT ROWID tables. check-in: 35a36060 user: drh tags: omit-rowid
2013-10-22
18:01
The Index object now has nKeyCol and nColumn. nColumn is the total number of columns and nKeyCol is the number of key columns. Currently these always differ by one. Refactor aiColumn[] to be of type i16 instead of int. check-in: a106ce86 user: drh tags: omit-rowid
14:28
Add a procedure to handle the messy details of allocating an Index object from the heap. check-in: 45efc94f user: drh tags: omit-rowid
10:23
Extra backwards-compatibility tests verify that UNIQUE and PRIMARY KEY indices are created in the correct order. Other backwards-compatibility tests already cover this, but it does not hurt to double up. check-in: 5ca0ea2e user: drh tags: omit-rowid
01:18
Previous refactor is not going to be helpful because implied indices must be created in the same order that they appear in the CREATE TABLE statement for backwards compatibility. This is a much smaller change to clean up a few loose ends. check-in: 824b549f user: drh tags: omit-rowid
2013-10-21
02:14
Simplification of the syntax: Merely append "WITHOUT rowid" to the end of the table definition. check-in: 131cc6e1 user: drh tags: omit-rowid
