After opening, I want to do some basic checking of my database.
I’m finding integrity_check much too slow for some of my users (especially with
large amounts of data) but I don’t want to just blindly trust the database
either.
A few options:
- Rely on what sqlite does on its own when I start

Just use sqlite3_busy_timeout.

I was looking over the requirements for sqlite3_open_v2(), and I'm not
clear if this function can ever return SQLITE_BUSY.
I initially wrote code to handle this case by sleeping and trying
sqlite3_open_v2() again, but it is untested and I've spotted one bug
in it already (I wasn't calling

I would really like to have a few of sqlite3's internal functions
available to client applications in a
Can Final be called without Step first being called?
If Step is called, will Final always be called?
I know the intention is to call sqlite3_aggregate_context with the
size I really need and not allocate anything myself, but I want to
store a pointer to a C++ class in the aggregate context.

According to the web page, 3.5.3.

Use -MM-DD instead of M/D/Y. Available formats described here

That's not what a bind point looks like. Take a look here:

Well, the page definitely doesn't validate:

I though it might be a good idea to test it before suggesting a
solution.
However, it only works with the results of queries and not with the
built-in
commands.
Just now I opened a bunch of shells, pasted the same query into all of
them, and closed the ones I didn't want after seeing the result.
So I ran .databases to see which databases I'm actually left with, and
saw something like this (not exact):

It shares what tables are used and what indexes, but as I understand

Yeah. My first thought when I brought up that page was "There's no way
I'm reading all that text!"... and I already use sqlite. I like the
points it goes over, though.
Does anyone know of a good sql formatter that's compatible with
sqlite3's syntax?
I'm looking for a command line-based tool with sources that can be
cross-compiled to the usual suspects (Win32, Unix, Mac OS X).
