| 00:30 | API Change: Modify sqlite3_enable_load_extension() so that it only enables/disables the load_extension() SQL function, and leaves the C-APIs enabled at all times.

| 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) file: [061a520a] check-in: [da61aa1d] user: drh branch: trunk, size: 12582 | |
