13 check-ins using file www/lang.tcl version bbff2feb

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

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

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

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

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

Update trigger2.test to match checkin 591. Also fix ticket #51 (by documenting problem) (CVS 595) check-in: 5e74d096 user: danielk1977 tags: trunk
