Hi,
Does anyone on the list use the sqlite3 gem with Ruby? Is this list ok to post
sqlite/ruby questions?
Many thanks in advance
Mike

True. Though now that you mention it, it would obviously be useful to
be able to trigger from a select.

In order to reduce SQLite's memory footprint in my embedded
application, I want to use the SQLITE_OMIT_xxx options to
remove unneeded features from SQLite.
Using Cygwin running on Windows, I have successfully down-
loaded the canonical sources and autoconfigured the Makefile.
The Makefile seems

I'll ask this question. The answer is probably "no," but I'll ask it
for the sake of completeness.

Read your records, parse and format into some known format by your
application. Write the data to disk in a file.
Then put a single entry into a sqlite table. specifing the on disk file name.

Hi,
does SQLite have anything similar to PostgreSQL's cidr data type (see
http://www.postgresql.org/docs/8.3/interactive/datatype-net-types.html).
I would be particularly interested in being able to use a "contained in"
operator in selects - in PostgreSQL you are able to do:
select inet
I have a rather opaque application that is calling my db. Is there
something I can turn on in SQLite that will log all the statements
executed against it?

You will have to open the memory database and attach the db file since
SQLite can't attach to a memory database.

If the sqlite statement had a temporary storage area so that I could
load up a bunch of rows and then commit them in one shot so that the
lock on the db was not held very long by a single transaction, that
would probably work.

sqlite3_close() closes the database connection opened by sqlite3_open().
You use it when you are done with a database connection.
Hi All,
The question that I had is when we need to use the sqlite3_close.
The reason that I have this question because I had the following codes and it
crashed if the sqlite3_closed is used.
Below is the codes:

hi!
I need to set up multiple writers to an in-memory datastore. I just
discovered that you can't have more than one connection to an in-
memory store.
I can give each task its own independent datastore if there is a way I
can merge the contents of each store into a central store. Is there

I recall reading that you should set the page size to the cluster size of
your disk. I think 4KB clusters are typical on Windows, and the SQLite
cluster size is 2KB if I remember correctly, so I bumped that up. I've

well,

Is there any suggestion or rules about parameters to use (cache_size,
default_cache_size...) in relation to database size and number of records in a

Certainly. You're benefitting from an OS that does file caching. If you

Are you using the 16 bit calls? Like:
sqlite3_prepare16_v2
sqlite3_column_text16
sqlite3_open16
That's what I use and I'm able to store and retrieve every non-Latin character
I've tried so far.

Thanks for your reply.
So, as I understand, this performance improvement is due to the operating
system, not to sqlite itself.
Could this improvement be different changing operating system?

Scott,
Because of the issues that you have raised I realized that multiple
configuration commands rolled into one transaction is not a good idea and is
not necessary. The router will act on a single command from any CLI session.
As far as command action goes it will be connection less towards

Did you compile sqlite with "--enable-threadsafe"
I use sqlite in multithread, connect db in each thread(often two thread);
After several times insert, I run PRAGMA integrity_check, display this message:
"wrong # of entries in index sqlite_autoindex_msglog_1"
Is index not threadsafe?
