17 check-ins using file src/parse.y version c681da70

2002-06-02
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)

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)

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)
