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

12:45

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)

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
11:47
Added documentation about the new CASE expression. (CVS 552) (check-in: cc541b10 user: drh tags: trunk)

2002-04-30
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)

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)
2002-04-22
00:35

2002-04-20
14:45
