Of course I tried this, but with a single bracket I got a syntax error.
With double bracket it works.

I'd recommend NOT relying on the system sqlite3. That way you can control your
changes.
Get the amalgamation and put sqlite3.c and sqlite3.h in your project.
And, you forgot to put in the name for -o -- so you would get a file named
-lsqlite3 in your directory.
And you'll probably need

Hi guys, i'm working on an Android app and using sqlite to store some data
and i need some help with a query.
I have the following table structure:
FILES
file_id INTEGER NOT NULL,
name TEXT
DATA
file_id INTEGER REFERENCES files(resource_id) ON DELETE CASCADE,
data_type TEXT,
value TEXT
This has to run as fast as possible. A left join between these tables is too
slow, for 10.000 entries it takes around 15 seconds just to navigate through
the cursor, if I add a where clause selecting only one kind of data then it
reduces to less than 5 seconds which is acceptable.

Use the sqlite3 command-line shell to dump the database to SQL commands, then
create a new database by reading it back in.
While the data is in the SQL command file, you can

Probably your DBF file was exported as MBCS. You need to convert the MBCS
from the export into utf8 or utf16 prior to import into SQLite.
