| 11:41 | Update the file-format change document to describes the changes between versions 2.4.12 and 2.5.0. (CVS 633) check-in: d28a2ecc user: drh tags: trunk | |
| 11:36 | This patch contains the beginnings of the data-typing infrastructure. The new build-in TypeOf() function is added. New opcodes for doing pure text comparisons are added. Most changes are disabled pending the 2.6.0 release. (CVS 632) check-in: cbbc858d user: drh tags: trunk | |
| 03:38 | Fix for ticket #73: The ORDER BY clause is significant for subqueries. This passes all regression tests, but more testing is needed to exercise all paths through the new code. (CVS 631) check-in: 43c5aff5 user: drh tags: trunk | |
|
2002-06-19
| ||
| 20:32 | Fix for ticket #75: Autoincrement INTEGER PRIMARY KEY fields on an INSERT even if the data is coming from a SELECT statement. (CVS 630) check-in: d599f75b user: drh tags: trunk | |
| 14:27 | Version 2.5.1 (CVS 629) check-in: 5e8a3131 user: drh tags: trunk | |
| 14:27 | The query optimizer now attempts to satisfy an ORDER BY clause using an index. Sorting is still used if there are no suitable indices. (CVS 628) check-in: f09e19b4 user: drh tags: trunk | |
|
2002-06-17
| ||
| 17:26 | Version 2.5.0 (CVS 627) check-in: 9baef3e2 user: drh tags: trunk | |

|
2002-06-16
| ||
| 18:21 | Expose an additional internal API routine (sqliteInitCallback()) for use by private code. (CVS 624) check-in: cd74495f user: drh tags: trunk | |
| 04:57 | Added explanation and examples for %Q format specifier. (CVS 623) check-in: 633ce4dd user: chw tags: trunk | |
| 04:56 | Added printf-4.(2-4) test cases to test new %Q format specifier. (CVS 622) check-in: 7d5fc35b user: chw tags: trunk | |
| 04:55 | Added %Q format specifier: like %q but automatic enclosing in single quotes, NULL pointers replaced by NULL w/o single-quotes. (CVS 621) check-in: b9c7ecc2 user: chw tags: trunk | |
| 04:54 | Changed sqlite_mprintf_str to allow a NULL string parameter. Command template now is cmd FORMAT INT INT ?STRING?. When STRING omitted a NULL is passed to sqlite_mprintf. (CVS 620) check-in: 8bc71157 user: chw tags: trunk | |
|
2002-06-14
| ||
| 22:38 | Make the LIMIT clause work even if the destination of the SELECT is something other than a callback. (Ticket #66) (CVS 619) check-in: 699cf362 user: drh tags: trunk | |
| 20:58 | Improvements to comments. No code changes. (CVS 618) check-in: 7e10e60b user: drh tags: trunk | |
| 20:54 | Fix for bug #72: Make sure the file descriptors are properly closed if sqliteInit() fails for any reason. (CVS 617) check-in: e67ac0fe user: drh tags: trunk | |
|
2002-06-12
| ||
| 22:33 | Fix for bug #70: Correct a typo in the documentation. (CVS 616) check-in: 3387d5b6 user: drh tags: trunk | |
|
2002-06-11
| ||
| 22:33 | Documentation that should have been checked in along with checkin (614) (CVS 615) check-in: 10da1361 user: danielk1977 tags: trunk | |
| 02:25 | Add RAISE() function, which allows more advanced flow-control in trigger programs (ticket #55) (CVS 614) check-in: d4a2fb10 user: danielk1977 tags: trunk | |
|
2002-06-09
| ||
| 10:14 | Fix the spelling of sqliteRegisterBuiltinFunctions(). (CVS 613) check-in: 74d297d9 user: drh tags: trunk | |
| 01:55 | Added tests for the new IN operator optimizer and fixed a bug that the new tests found. This completes the implementation of enhancement #63. (CVS 612) check-in: 2a710e18 user: drh tags: trunk | |
| 01:16 | Fix for ticket #65: If an integer value is too big to be represented as a 32-bit integer, then treat it as a string. (CVS 611) check-in: ad962479 user: drh tags: trunk | |
|
2002-06-08
| ||
| 23:25 | Add optimizations for the IN operator in WHERE clauses. This is a partial implementation of enhancement #63. Still need to add test cases. (CVS 610) check-in: 8481e841 user: drh tags: trunk | |
|
2002-06-06
| ||
| 23:42 | Bug fix: do not segfault if a SELECT without a FROM clause includes the * wildcard in the result column list. (CVS 609) check-in: d9392949 user: drh tags: trunk | |
| 23:30 | Fix for ticket #59: Add documentation for the || operator. Also added documentation for the new SQL92 join syntax. (CVS 608) check-in: a0abef62 user: drh tags: trunk | |
| 23:16 | Fix for ticket #62: Do not report an SQLITE_READONLY error until the application actually tries to write data into a readonly file. It is OK to start a transaction on a read-only file, and doing so will get you a read lock. This change allows TEMP tables to be read/write even though the main database is readonly. (CVS 607) check-in: 9ef795d1 user: drh tags: trunk | |
| 19:04 | Additional grammar cleanup resulting from the %fallback directive. (CVS 606) check-in: c0cb3a01 user: drh tags: trunk | |
| 18:54 | Added the %fallback directive to the lemon parser generator and used this in the parser to make the parse tables much smaller. This reduced the size of the library by 15K. (CVS 605) check-in: 7ac5bd29 user: drh tags: trunk | |
|
2002-06-02
| ||
| 18:22 | Fix a compiler warning. (CVS 604) check-in: 637ee587 user: drh tags: trunk | |
| 18:19 | Add the ability to parse FOREIGN KEYs. Foreign keys are still ignored, but at least they now do not cause a syntax error. (CVS 603) check-in: 6fdcee3c user: drh tags: trunk | |
| 16:09 | Enhance the ORDER BY clause so that an integer term means to sort by the corresponding column. (CVS 602) check-in: 7acbf84b user: drh tags: trunk | |
|
2002-06-01
| ||
| 21:41 | Multiplying NULL by zero gives NULL, not zero. I misread the test data and coded it wrong. This check-in fixes the problem. (CVS 601) check-in: df9cc852 user: drh tags: trunk | |
|
2002-05-31
| ||
| 15:51 | Refinements to NULL processing: NULLs are indistinct for DISTINCT and UNION. Multiplying a NULL by zero yields zero. In a CASE expression, a NULL comparison is considered false, not NULL. With these changes, NULLs in SQLite now work the same as in PostgreSQL and in Oracle. (CVS 600) check-in: da61aa1d user: drh tags: trunk | |
|
2002-05-30
| ||
| 12:27 | Once it is opened, leave the checkpoint journal file open for the duration of a transaction, rather than closing it and reopening it for each statement. (Ticket #53) (CVS 599) check-in: 7a24336d user: drh tags: trunk | |
| 02:35 | Bug fix: bad code was generated for when the first operand of a CASE was NULL. (CVS 598) check-in: 4debc8db user: drh tags: trunk | |
|
2002-05-29
| ||
| 23:22 | Built-in aggregate functions (MIN, SUM, AVG, etc) should ignore NULL entires. (CVS 597) check-in: 19ae12be user: drh tags: trunk | |
| 12:44 | Remove extra \ characters from temporary filenames under windows. (Ticket #52) (CVS 596) check-in: ed11abc8 user: drh tags: trunk | |
|
2002-05-28
| ||
| 06:55 | Update trigger2.test to match checkin 591. Also fix ticket #51 (by documenting problem) (CVS 595) check-in: 5e74d096 user: danielk1977 tags: trunk | |
|
2002-05-27
| ||
| 12:24 | A SELECT statement inside the body of a TRIGGER uses the SRT_Discard target to discard the query results. Such selects are intended to be used to call user-defined functions for their side-effects. They do not return results. (CVS 594) check-in: f8041f3d user: drh tags: trunk | |
| 03:25 | Fix the "alias.*" bug found by Bernie Cosell and reported on the newsgroup. (CVS 593) check-in: f562d542 user: drh tags: trunk | |
| 01:04 | Bug fixes and additional test cases for the distinct-NULL patch. (CVS 592) check-in: 0e268d0c user: drh tags: trunk | |
|
2002-05-26
| ||
| 23:24 | Require the INSTEAD OF syntax to create triggers on database views. (CVS 591) check-in: d9e48cd5 user: danielk1977 tags: trunk | |
| 21:34 | Change functions to handle NULLs correctly. Added the NULLIF() function. (CVS 590) check-in: 46ce1a9a user: drh tags: trunk | |
| 20:54 | NULL values are distinct. A comparison involving a NULL is always false. Operations on a NULL value yield a NULL result. This change makes SQLite operate more like the SQL spec, but it may break existing applications that assumed the old behavior. All the old tests pass but we still need to add new tests to better verify the new behavior. Fix for ticket #44. (CVS 589) check-in: 90511737 user: drh tags: trunk | |
|
2002-05-25
| ||
| 00:18 | Additional testing of LEFT OUTER JOIN. (CVS 588) check-in: d8d04c14 user: drh tags: trunk | |
|
2002-05-24
| ||
| 20:31 | Initial implementation of LEFT OUTER JOIN including the expanded SQL92 join syntax. The basic functionality is there but there is still a lot of testing to do. (CVS 587) check-in: 99bd1f5b user: drh tags: trunk | |
| 16:14 | Add support for the full SQL join syntax. This is just a parser enhancement. We now recognize all kinds of joins, but we don't actually do anything with them yet. (CVS 586) check-in: e238643e user: drh tags: trunk | |
| 02:14 | Added tests for multi-column primary keys. (CVS 585) check-in: ffc49e56 user: drh tags: trunk | |
| 02:04 | Split the IdList structure into IdList and SrcList. SrcList is used to represent a FROM clause and IdList is used for everything else. This change allows SrcList to grow to support outer joins without burdening the other uses of IdList. (CVS 584) check-in: a167b71d user: drh tags: trunk | |
|
2002-05-23
| ||
| 22:07 | Change the names of the PushList and PopList opcodes to ListPush and ListPop so that they will appear together with the other List opcodes in the documentation. (CVS 583) check-in: c53b0b92 user: drh tags: trunk | |
| 13:15 | Fix for ticket #50. (CVS 582) check-in: 82b74a49 user: drh tags: trunk | |
| 12:50 | Partial fix for ticket #49. The correct result is computed, but now we have a memory leak. I'm not sure if the memory leak was pre-existing or a result of this change. (CVS 581) check-in: 4d27ee41 user: drh tags: trunk | |
| 02:09 | Fix some places where a malloc() failure would lead to a segfault. (CVS 580) check-in: 01ad352c user: drh tags: trunk | |
| 00:30 | Do not allow triggers on the SQLITE_MASTER table. (CVS 579) check-in: 275ba356 user: drh tags: trunk | |
|
2002-05-22
| ||
| 21:27 | Fix for ticket #46: Report an error if a CREATE TABLE contains two or more columns with the same name. (CVS 578) check-in: ba1953ab user: drh tags: trunk | |
|
2002-05-21
| ||
| 23:44 | Fix for ticket #47: Use a cast to avoid a warning about discarding a "const" inside of hash.c. (CVS 577) check-in: 0c903461 user: drh tags: trunk | |
| 13:43 | Double-quoted strings resolve to column names if possible. Single-quoted strings continue to be interpreted as string literals. (CVS 576) check-in: 55e7d654 user: drh tags: trunk | |
| 13:18 | Clean up some compiler warnings. (CVS 575) check-in: 3399b012 user: drh tags: trunk | |
| 13:02 | Modify the shell so that when it is doing a ".dump" it always uses single quotes and not double quotes for quoting literal strings. This is for portability to other databases that only support single quote string literals. (CVS 574) check-in: f795afd6 user: drh tags: trunk | |
| 12:56 | Fix for ticket #45: Allow an UPDATE statement to change the INTEGER PRIMARY KEY to itself without triggering a constraint error. (CVS 573) check-in: 592da134 user: drh tags: trunk | |
| 11:38 | Additional code cleanup resulting from a review of the new trigger code. (CVS 572) check-in: 37dbdd55 user: drh tags: trunk | |
|
2002-05-19
| ||
| 23:43 | Style fixes to triggers code in various *.c files (partial fix to ticket #39) (CVS 571) check-in: 8a4195c7 user: danielk1977 tags: trunk | |
|
2002-05-17
| ||
| 00:05 | Stylistic changes to src/trigger.c (partial fix to ticket #39). Also more comments. (CVS 570) check-in: b1d72cb5 user: danielk1977 tags: trunk | |
|
2002-05-16
| ||
| 00:13 | Fix for ticket #42: Added comments to structs Trigger, TriggerStep and TriggerStack. (CVS 569) check-in: 9ec8a2b1 user: danielk1977 tags: trunk | |
|
2002-05-15
| ||
| 23:26 | Fix a typo in the c_interface.html documentation file. (CVS 568) check-in: 454879fa user: drh tags: trunk | |
| 14:17 | Fix for ticket #41: Better handling of CREATE TRIGGER in the sqlite_complete() function. (CVS 567) check-in: f45c4b76 user: drh tags: trunk | |
| 12:45 | Beginning to clean up the trigger code. Still lots of work to do. (CVS 566) check-in: b1034681 user: drh tags: trunk | |
| 11:44 | Remove all tabs from the beginning of source code lines. Replace tabs with the appropriate number of spaces. (CVS 565) check-in: 690f9a16 user: drh tags: trunk | |
| 11:43 | In the "lang.html" documentation file, put the CREATE TRIGGER and DROP TRIGGER sections in alphabetical order. (CVS 564) check-in: d1d8642b user: drh tags: trunk | |
| 08:43 | Add the Makefile.in that was forgotten with checkin #562 (CVS 563) check-in: 29b8330c user: danielk1977 tags: trunk | |
| 08:30 | Added FOR EACH ROW triggers functionality (CVS 562) check-in: 794bf67b user: danielk1977 tags: trunk | |

| 14:37 | Update the misuse.test script so that it will work under Windows. Changes to the speed testing script to support version 2.4.12. (CVS 560) check-in: 232b7ef2 user: drh tags: trunk | |
| 13:14 | Improvements to the SQLITE_MISUSE detection logic. Also added test cases for this logic, including the new test file "misuse.test". (CVS 559) check-in: f42907ce user: drh tags: trunk | |
| 05:44 | Attempt to detect when two or more threads try to use the same database at the same time and return an SQLITE_MISUSE error. Also return this error if an attempt is made to use a closed database. (CVS 558) check-in: a05fabd2 user: drh tags: trunk | |
|
2002-05-08

| 11:54 | Fix for tickets #32 and #33: Generate the names of the result set early, before doing the flattening optimization or evaluating subqueries. Otherwise, the result set column names are generated incorrectly or after they are needed. (CVS 553) check-in: 08f27cb3 user: drh tags: trunk | |
|
2002-05-06
| ||

| 19:20 | Fix for ticket #31: Do not attempt the flattening optimization if the subselect does not contain a FROM clause. Handle the special case where a WHERE clause is constant. (CVS 548) check-in: 24e4cf73 user: drh tags: trunk | |
|
2002-04-26

| 09:47 | Fix for ticket #28: Export the "sqlite_changes" function in Windows DLLs. (CVS 547) check-in: f7cea463 user: drh tags: trunk | |
|
2002-04-25
| ||
| 23:06 | Update the test logic and the comments on the encoder.c module. (CVS 546) check-in: 18c28519 user: drh tags: trunk | |
| 11:45 | Added the "encode.c" source file that contains two utility subroutines that can be used to encode binary data for use in INSERT and UPDATE statements. This is just an initial checking. The code has not yet been integrated into the library. (CVS 545) check-in: 57f7c597 user: drh tags: trunk | |
| 00:21 | Fix for ticket #26: Document the fact that CREATE TABLE might not be immediately visible to other processes that are holding the database open. (CVS 544) check-in: 18b31b7a user: drh tags: trunk | |
|
2002-04-23
| ||
| 17:10 | Fix for ticket #22: In the code generator for compound SELECT statements, take care not to generate column name headers if the output is an intermediate table. Otherwise the column headers are not generated correctly if a compound SELECT statement appears as an expression in part of the WHERE clause. (CVS 543) check-in: a06d9acd user: drh tags: trunk | |
