Hello Stefan,
I'm trying to use the code snippet you suggested but when I try to query
the master table of the attached database I get and error with the
following message:
"SQL error: no such table: 'test.sqlite_master';
I am running the following queries:
1. "ATTACH DATABASE 'data\\test.db' AS test" - this seems to succeed (no
error code).
2. "SELECT tbl_name FROM test.sqlite_master' WHERE type = 'table'" -
this one is failing.
Do you have any ideas? I tried looking at the docs but there doesn't
seem to be much about it, from what I've read the queries appear to be
correct.

What do you mean by loading it into memory?
If you want to dump the on-disk tables into memory and also want to
check the memory footprint used for caching try this:
Open the :memory: database and attach the on-disk database with
ATTACH filename.db AS filename
Then do a
CREATE TABLE tableName AS SELECT * FROM filename.tableName
On each table in the file, thus creating an in-memory copy of the DB and
having done a select on each table (i.e. you'll see how much cache in
memory will be used, etc.)
You can enumerate all tables in a your on-disk-file in the mentioned
scenario by doing a "SELECT tbl_name FROM filename.sqlite_master WHERE
type = 'table'".
Best regards,
Stefan.
