2002-07-11
12:18
Turn of the reporting of datatypes in the 4th callback argument unless the SHOW_DATATYPES pragma is ON. Eliminate the NULL pointer that used to separate the beginning of datatypes from the end of column names so that the callback can test to see whether or not datatypes are provided. This is an incompatible changes, but since the prior behavior was never documented, we will let it in. (CVS 670) check-in: b9872724 user: drh tags: trunk
2002-07-10
21:26
When reporting back the datatype of columns, use the text of the datatype as it appears in the CREATE TABLE statement, if available. Also: removed the ".reindex" command from the shell. (CVS 669) check-in: ff8b6f4e user: drh tags: trunk
2002-07-08
22:03
Add support for TEMPORARY views. The code is here but it is mostly untested. (CVS 668) check-in: 87cd10c1 user: drh tags: trunk
10:59
In the BTree subsystem, when using pages from the freelist, attempt to select pages close to related pages in order to keep data structures near each other in the database file. This improves access speed in some circumstances. (CVS 667) check-in: fd7e41f0 user: drh tags: trunk
02:16
Make the BTree balance() routine a little faster by reusing database pages locally rather than freeing and reallocating them. (CVS 666) check-in: 3c2dea43 user: drh tags: trunk
2002-07-07
17:13
Version 2.5.6 (CVS 664) check-in: 111c78e6 user: drh tags: trunk
17:12

16:52
More rollback problems: Fix two more errors introduced by checking (410) that can cause database corruption after a ROLLBACK. Also add new tests to make sure everything is working this time. (CVS 663) check-in: f6e24d5c user: drh tags: trunk
2002-07-06
16:34
Version 2.5.5 (CVS 662) check-in: 6284c65c user: drh tags: trunk

16:28
Fix for bug #94: Be sure to journal pages that are added to the freelist then removed from the freelist and reused during the same transaction. (CVS 660) check-in: db178646 user: drh tags: trunk
2002-07-05
21:42
All the code is now in place for SQLite to distinguish between NUMERIC and TEXT datatypes. Still need to turn on the new code and test it. (CVS 659) check-in: b4737a16 user: drh tags: trunk
2002-07-02
13:05
Fix for ticket #92: Correct the sqliteExprCompare() function so that is takes into account the iTable and iColumn fields of the Expr structure. Otherwise, "min(a)" and "min(b)" will compare equal to each other in views. (CVS 658) check-in: 85793a4f user: drh tags: trunk
11:55
Fix for ticket 91: Modify the "publish.sh" script to use the new mingw cross-compiler installed on the development platform. (CVS 657) check-in: 3cac283d user: drh tags: trunk

2002-06-28
12:18
Additional test cases added. The following bug fixed: A segfault was occurring if a VIEW consisted of a join with a USING clause. (CVS 651) check-in: 96515b81 user: drh tags: trunk
01:02
Fix for ticket #84: If the WHERE clause is too complex, issue an error message and refuse to do the SELECT. The cutoff is a WHERE clause with 100 terms. (CVS 650) check-in: c07e493b user: drh tags: trunk
2002-06-27
13:21
Fix for ticket #88: A typo in the documention of the "sqlite" shell command. (CVS 649) check-in: 16552a7a user: drh tags: trunk
2002-06-26
20:06
In the TCL interface, the "sqlite" command now always returns the address of the "sqlite*" pointer that sqlite_open() returns. It used to do this only when compiled with the SQLITE_TEST macro defined. (CVS 648) check-in: 9ca63685 user: drh tags: trunk
02:45
The datatype of the i-th column in the result set is given by the azColName(argc+1+i) parameter to the callback. (CVS 647) check-in: bdb006b8 user: drh tags: trunk
2002-06-25
19:31

15:19
Version 2.5.3 (CVS 645) check-in: d5cb6754 user: drh tags: trunk
14:46
Fix a spelling error in the change log. (CVS 644) check-in: 37cc4044 user: drh tags: trunk
14:43
Bug fix: When the database file grows in size during a transaction, make sure the last page of the file gets written to disk even if that page is on the free list and contains no data. Otherwise the disk file will be too small which can lead to database corruption in subsequent transactions. (CVS 643) check-in: 36fc0add user: drh tags: trunk
13:16
Enhance the INTEGRITY_CHECK pragma to test the auxiliary database file in addition to the main database file. (CVS 642) check-in: 52eba4de user: drh tags: trunk

Version 2.5.2 (CVS 641) check-in: 756310ca user: drh tags: trunk
01:09
Added support for the "sqlite_temp_master" table. Increased the version number to 2.5.2. (CVS 640) check-in: 9c1432bf user: drh tags: trunk
2002-06-24
22:01
Partial fix for a problem with LEFT OUTER JOIN. It used to be that the test for the right-hand table not matching the left table occurred after all ON, USING, WHERE clause processing. The test should occur after ON and USING clauses are checked but before the WHERE clause is check. This fix works as long as the total number of "AND" separated terms in the ON, USING, and WHERE clause does not exceed 32. To do: make this work for any number of terms and add test cases. that (CVS 639) check-in: 8b6574cf user: drh tags: trunk
12:20
Fix a VDBE stack leak in LEFT OUTER JOIN. Fix a bug in the code generator for JOIN ... USING(...). (CVS 638) check-in: d861489e user: drh tags: trunk
2002-06-22
02:33
An optimization: avoid the use of an intermediate table on UNION ALL if there is no ORDER BY clause. (CVS 637) check-in: 8aa73ce6 user: drh tags: trunk
2002-06-21
23:01
Fix for bugs #77 and #80: Rework the LIMIT mechanism to be reentrant and to clean up the VDBE stack properly. (CVS 636) check-in: 9d552310 user: drh tags: trunk
13:09
Fix for ticket #76: Fix a database corruption that might occur when dropping tables or indices. (CVS 635) check-in: 7936b032 user: drh tags: trunk
11:55
Fix for ticket #78: Avoid an assertion failure when sqlite_close() to be called in the middle of a transaction. (CVS 634) check-in: 2532792a user: drh tags: trunk
2002-06-20
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
17:15
Update the change summary for version 2.5.0 (CVS 626) check-in: 7a216ade user: drh tags: trunk
17:07
Add preliminary logic for the eventual move to having separate TEXT and NUMTEXT datatypes. Also change the version number to 2.5.0 in preparation for an interim release. (CVS 625) check-in: 05783a9d user: drh tags: trunk
2002-06-16

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
