Wow, what a great feature. This saves me so much hacking!
I planned on using virtual tables but per-query instance creation and
parameter passing was going to be such a mess.

You are confusing things. The
The LINQ provider for System.Data.SQLite does not provide this function
directly; however, it may be possible to use one of the core date-time
related SQL functions to do it?

That has three very likely causes. The first is that your internal

Hi,
I'm a regular user of SQLite, but a first timer in this list. A few months
ago, while doing some intensive but manual data processing, I created
(hacked) a loadable module that allowed me to run short Lua scripts
directly inside the SQL queries. That eased a lot of the work that day.
I'm

Are you checking the values returned by sqlite3_prepare, sqlite3_bind, and
sqlite3_step, to make sure they return SQLITE_OK ?
I'm not quite sure what you mean by 'done once' -- whether it's once for the
whole
Of course that is the aim, as always.
In this particular case, maximally portable code (that will compile and execute
correctly on all conforming compilers) must (a) ensure that the pointer
argument is valid (b) ensure that the length is valid, or zero. Where

Could this not be achieved by two indexes: one partial and one complete?
CREATE UNIQUE INDEX idx_books1 ON Books(title, author);
CREATE UNIQUE INDEX idx_books2 ON Books(title) WHERE author ISNULL;
To save space and (maybe) time, you could put a 'WHERE author NOTNULL' on the
first index.

My iOS app displays a gallery of thumbnails in a tableView (four to a row). To

This will work great - just a correction, there should be a comma after
"columnB" in the order by clause, else it might not parse, so the
revised is:
SELECT * FROM table
ORDER BY columnA, columnB,
CASE WHEN columnC = 1
THEN 0 ELSE 1 END;
