what encoding does sqlite_exec() callback function receive data in ?
some tests i've done seem to suggest UTF-8
other tests show chars U+80 to U+FF are returned as single chars with
values 128-255. (suggesting its not UTF-8)
where is *any* documentation about this?

problem:
SQL error: no such table: input_queue
but when i check it using the commandline app, its clearly there.
i just created another table called 'test' with 1 col of integers and
inserted '34'and it .dumps OK (using the command line app)
but says :SQL error: no such table: test
ha
Oh, it created one in the cwd, not the place where i thought the DB
should be...
is there a way to turn that 'feature' off, so that i can prevent that
from happening, i'd prefer just an error.

base64_encode( &myS, buf, sizeof(s) );
INSERT INTO table ( myTextField ) VALUES ( 'buf' );
then retrieval is the opposite.

I would like to use math with more then one table, for example
I know how to do this

but i don't know how with an additional table, i came up with
UPDATE Records,Table2
SET Factors= (Factors * Potential Table2
Defragging the database just removes empty pages making the database
file smaller. It doesn't actually touch any data.
Have a look here:

Thank you for any insight into this. The database is working fine as-is,
but I am trying to see for the sake of convenience and education if I
compiled Python version, but for my own personal
projects I will try to fiddle with attach. The ability to split the database
into multiple files will come in handy if I end up tackling anything larger.

difference. These rows are probably on the order of 200-300 bytes each so if
I do the math, something in the 210-250 gb range seems reasonable.

Ah, this tool seems very handy. For those curious, I'll paste the results
below. The index approximately doubles the storage size, but I am
intentionally making that tradeoff to avoid the slow down when enforcing a
unique/primary key on the Reference table while inserting.

Was this never implemented? Is it deprecated? Does it require special build
options? Any thoughts?

do it like this
sqlite3 -init meta-fts.table.sql meta-fts-new.sqlite3
where `meta-fts.table.sql` is https://gist.github.com/3154874
wget
https://raw.github.com/gist/3154874/8f582883d62c82aeafed5eabf639e603ec1ac379/meta-fts.table.sql
Then it throws the error.

While I respect that many users will want to implement a custom solution,
it seems that the solutions mentioned solve the 90/10 problem.
If not, to whom should I propose that the 'good enough' functions mentioned
in the documentation should be part of the stan
rk again.
And when I go back to the previous terminal window it fails again.
What about my terminal session / environment might be contributing to this
behavior?

It appears that the original version of sqlite3 that shipped with OS X is
still in the PATH of the old terminal, but the new one installed with brew
in loaded in the new on.
Thanks for helping me figure this out!

That example isn't from a 3rd party. It's the rank function listed here:

Can you give me a link to documentation for what options to pass to gcc and
what functions to call to activate such an extension?

Now I see a number which matches my expectations:
SELECT hex(matchinfo(t1)) FROM t1 WHERE t1 MATCH 'default transaction
"these semantics"';

I imagine that most users who are following this documentation for the
first time are using the sqlite3 binary and following along by copying and
pasting the examples.

sqlite3_create_function(db, "testfn", -1, SQLITE_ANY, 0, testfn, 0, 0);
testfn("1", "2", "3"); -- nVal is 3
testfn("1", "2"); -- nVal is 2
testfn(matchinfo(documents)); -- nVal is 1
testfn(matchinfo(documents), 2, 3, 4,
(documents))
Seems that it would be best to assign a default weight of 1 if nVal == 1 or
the double value of apVal[1] otherwise.
Also the line
double weight = sqlite3_value_double(apVal[iCol+1]);
should be simplified to:
double weight = sqlite3_value_double(apVal[1]);

I also found an error in the signedness of ints (using -Wall -Werror).
The corrected code here functions as described in the documentation's

What about that paragraph indicates that the sqlite3 cli doesn't know how
to pretty-print understand its own native types?

that a column isn't supplied it makes sense to use a default weight of 1.0
if the weights aren't supplied.
