After thinking about your post, the sqlite alter limitation is sqlite
specific. Maybe their sqlite Bryson takes this info account? I usually use the
free odbc one but it is slow...

Is there a tool that allows you to graphically change sqlite schema as
simple as editing a spreadsheet? For example if I wanted to change a column
name from "my_driving_hours" to "driving_time", instead of writing a line
of code, I can just click on that column and type in the new name, letting

Could be an interesting virtual table module...

Hello,
I would like to run the following update statement
if pragma user_version == 2.
How can I incorporate that in this query?
UPDATE pass_key
SET key = (SELECT textval FROM saved.pass_key b WHERE b.field='key')
WHERE name="KeyLock";
I've tried using CASE..WHEN..ELSE but it doesn't seem to

Isn't nanomsg the successor of ZeroMQ? I.e. same guy, same project, mark 4 or 5?

Hi SQLite team,
I have query with multiple select statements (attached below). When I run this
query on 3.8.0.2 sqlite3 it takes much more time than in took on same db in
3.7.17. In 3.7.17 it takes 0.093 sec, In 3.8.0.2 it takes couple of minutes.
Database has three tables product (3000 rows),

In practice, Hbase schemas are denormalized. But toa void storing all that null
data, they use column families. Anyone trying to use a cluster should know to
join everything as much as possible. But it is recognized that even for Hbase,
joins are an expensive and limiting operation. By
That's the whole point of using SQLite, it's not 'big iron' - it's a bunch of
iron filings working together.
I'm just suggesting the amount of work to get such a thing going is not that
much work, but I wanted to float it here to see if there were any good reasons
why it was a bad idea. :-)

You can get a nice surprise with SQLite when you feed it with the same RAM
amount you put on MySQL

First, look into VIEWs. You can save any SELECT as a VIEW, then

I was under the impression that a view is limited to the tables in the
db file where it resides, and have received error messages whenever I
tried to access another file's tables.
Hi, Jason,
It might be that this is a little bit to big for sqLITE.
Maybe a "big iron" database like PostgreSQL or the Greenplum Database will fit
your requirements better.

I'm transitioning my job from embedded space to Hadoop space. I was wondering
if it is possible to come up with a SQLite cluster adaptation.
I will give you a crash course in hadoop. Basically we get a very large CSV,
which is chopped up into 64MB chunks, and distributed to a number of nodes.

Sure! WFM. I thought that was what I was suggesting. 8-)
