I have a query that runs very quickly and returns no results:
SELECT * FROM filebackup WHERE sha1='x';
However, the more restrictive query below runs very slowly, although
it obviously can't have any results either:
SELECT * FROM filebackup WHERE sha1='x' AND refid=0;
I have indexes on both
I imported a file with ~16.8M rows of 2 integers each (~33.6M ints
total) into an SQLite db, no indexes. The ints are all < 16777216 (3
bytes)
At 3 bytes/int, I thought the resulting db would be ~100M in size
(plus some overhead), but it was actually 274M.
How do I make sqlite3 store ints
Consider a wiki that lets you edit rows in a db table. Each page is a
row in the table, and has fields that anyone can edit. Like all wikis,
it keeps a history of edits (including who made the edits), and lets
you revert an edit, or even delete a row (page) completely.
Has anyone implemented

I want to do multi-master sqlite3 replication by editing sqlite3.c to
log UPDATE/INSERT queries with timestamps, and then using another
program to run those queries on the other masters.
I looked at the sqlite3Insert() function in sqlite3.c, but couldn't
find a variable that holds the query
Many sites let you search databases of information, but the search
queries are very limited.
I'm creating a site that'll allow arbitrary SQL queries to my data (I
realize I'll need to handle injection attacks).
Are there other viable ways to query data? I read a little on
"Business System 12"
Is there any way to real-time replicate SQLite3 dbs across servers?
I realize I could just rsync constantly, but this seems inefficient.
I know SQLite3 uses a journal when making changes: could I use this
journal for replication, similar to how MySQL uses bin-logging for
replication?

On a website, I want to take a user's query "as is", save it to a
userquery.txt, and then do:
sqlite3 /path/to/mydb < userquery.txt
where /path/to/mydb is a *read-only* file.
Is there *any* risk of an injection attack here?
Specifically, does sqlite3 have any shell escapes or any way to change

Emacs' "forms mode" lets you edit a text file as though each line were
a database record.
Is there a similar mode that lets you edit data inside an sqlite3 db?

I have a text file onenum.txt with just "1234\n" in it, and a db w/
this schema:
sqlite> .schema
CREATE TABLE test (foo INTEGER PRIMARY KEY);
When I import, it fails as follows:
sqlite> .import onenum.txt test
Error: datatype mismatch
Is sqlite3 treating "1234" as a string or something? Short
I tried inserting 2^63-1 and the two integers after it into an SQLite3
db, but this happened:
SQLite version 3.6.11
Enter ".help" for instructions
Enter SQL statements terminated with a ";"

sqlite> INSERT INTO test VALUES (9223372036854775807);

I've seen many posts saying that SQLite2 can't handle OpenStreetMap's
large planet.osm data file:
http://planet.openstreetmap.org/planet-090421.osm.bz2
which is 5.4G bzip2 compressed, about 150G uncompressed.
Can SQLite3 handle this? Has anyone tried?
I tried to do this myself, but I'm on a
I have a hideous query that looks like this:

which takes forever to run. However, when I replace 'child' with
'anf.name' in the WHERE clause, it runs lightning fast (as

Given how cool SQLite is, has anyone created SQLite dbs of geonames,
tycho2, or other large data sets that are available for download via
FTP, HTTP, Torrent or similar mechanism?
I realize I could dl the raw data, create tables, import the data,
create indexes, etc, but it's much faster just to
