Perhaps the analogy is better the other way around - try driving a stick
shift after driving an automatic. Takes a gear change or two for you to
realise what the other pedal is for.
As you mention, this is a constant point of discussion on this board.
Perhaps 'Version 3 Data Types' should be

UPDATE table SET aColumn = someNewValue, numTouched = numTouched + 1

Please leave the current functionality as is.
I believe it is the role of the host language to perform any editing or
translation of data, such as the removal of leading or trailing spaces, not
the SQL engine.

Does the column need to be loaded with UTC? Why not just insert the column
with localtime already applied? It would make the SELECT you require
trivial:
SELECT * FROM table WHERE datefield = '2005-12-23'.

No. COUNT(*) of an empty result returns 0. COUNT(*) should always return an
integer value, never NULL. It is a row-based, rather than a column-based,
aggregate function.

A column value is null or not null; it cannot be said to equal null as null
has no value;

No, thank you for taking the time and effort for this very informative
post-mortem. There's some stuff here I didn't know, so my knowledge and

It's not possible for a column value to be equal to NULL; hence the SQL
syntax is 'IS NULL'. However, in an UPDATE statement, writing
'columnA=NULL' is valid, as in this context '=' is an assignment, not a
relationship operator.

SQLite generating the "create index" SQL DDL statement at the end of the
.dump output is the correct behaviour.
In my experience using a number of different DBMSs, the sequence of data
loading and then indexing is usually quicker than performing those
operations the other way round. In a
Or try:
.mode lines
.null
select * from tablename limit 1;
The output is more readable if tablename has many columns and also provides
some example data for each column.

UNION working correctly. UNION returns distinct values; UNION ALL returns
all rows (including duplicates).
