193a6b4142 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)

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)

5df72a5ad6 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)

f570f011eb 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)

f5905aa7be 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)
