Does sqlite not support table aliases in update statements? Is there a way
to work around this to get the affect of
update table1 t1
set col1 = col1 * 2
where col1 = (select avg(col1)
from table1
where col2=t1.col2);

Nope, no aliasing in the update itself.

Can this be done with a JOIN instead of a sub-SELECT ?
Not in SQLite, as the join clause is not supported in an update statement.
For such functionality, look at MySQL or Postgress which do support variation
of such syntax.
Something like this

I've been playing around with a geo-location database. I have a camera
mounted on our travel van. Periodically, it takes pictures of where we
are. I've written (OK, mostly re-written) various code I've found to
tag the pics with location, lat/lon, date, time, direction, speed, and

That is pretty much the path I was thinking of taking (or possibly externally

You're welcome. Since
I'm running into an issue with foreign keys where no matter what value I
supply for a child key, I get a foreign key mismatch error. Here are my
test tables.

mm.html);
system(echo ^/table^ mm.html);
I get a foreign Key mismatch error. No matter what value I supply for
FKeyColumn, even NULL, I get the same error.
Did you create unique index on t1 (RefColumn) ? IIRC, SQLite always
fails foreign key check if there's no index on a referenced column.
