VIADANA, Italy (January 16, 2007) - SQLabs today announced the
availability of SQLiteManager 2.5, their new SQLite database manager
tool for MacOS X and Windows.
SQLiteManager is a "next generation" GUI database manager for sqlite
databases, it combines an incredible easy to use interface w

Yes, that's exactly what we do: use the in-memory db until it comes time to
save, and then we open a file db, attach, and copy it to disk. At that time,
the journal files are created.
If there is a nice way to serialize an in-memory db to disk without having to
open/attach to a file db, I'm al

Hi,
I was wondering if anyone can help with a problem I have having with SQL.
I have a table 'people' in a Sqlite database with a column 'population'.
All I
want to do is to add up all the values in this column. When the data is
in an
Excel file, the column adds up to 8,581,774.
I used the SQl
Hi Umesh,
What is the table structure of your SQLite table? Is it what you want
it to be? I am assuming "population" should be integer, as you can't
really have fractional people.
Did you check your imported data and see if it looks the same as in Excel?
Did all the data import? Probably yes be

Ahhh .. yes they do have commas in them. I'll remove the commas and try

Yes, I did try that -- I should have mentioned it. When I create and drop the
index again, the amount of memory that Sqlite takes is effectively the same.
That is, to create the index once costs a lot of memory, and then future
deletions/creations does not change the amount of memory allocated

I am getting the "attempt to write a readonly database" on a database

files hanging around, and is not being accessed by any other process.
I am trying to drop a table from it using the sqlite3 shell. Any

How to read after the database was written by another process?
Reading function should wait until other process finishes writing and
unlocks the file. But in our case unlocking never hap
Sqlite is allocating cache memory and reusing it. That is not a bug, it
is a beneficial feature.
