If that were true, then I wouldn't be getting a very large speed-up when
enveloping write ops in an explicit transaction, would I?

Simon, does a real disk have to be a rotating hard disk? Is there problem
with SSDs as far as SQLite is concerned?

In case this gives somebody a clue, the server in question is on
http://vps.net/.

Hi,
On one of my hosting servers (this one is a VPS), a bunch of write
operations take practically the same amount of time when they are performed
individually as when they are performed as one explicit transaction. I've
varied the number of ops up to 200 -- with the similar results. Why is that?
I'd recommend http://www.sqliteexpert.com/. I've been using it for years
and like it.

Hi,
I started writing this message and then read
http://www.sqlite.org/lang_transaction.html, and I think I've gotten my
answer, but I will ask the question to be absolutely certain, particularly
when using SQLite with PHP (using PDO).
Probably based on flawed understanding of how SQLite worked,
Hi,
A recent discussion of a reader/writer problematic situation has
prompted me to ask the following question.
While the database file is being written to, the data isn't ready to
be used by readers, so that DB is locked. What happens if I initiate
copying of this file (e.g., to back it up)? Is
Alexey, I am not clear about whether you reported my bug or yours. Do
you mind giving me a link to it so that I could see if I need to
report mine and let it go?

So, you also think this is a bug? I will submit it to the SQLite bug database.

One could easily configure the server to *not* serve database files

Hi,
I would like to know if I am dealing with a bug or a backward incompatible
change that I am not aware of.
Consider this example:
CREATE TABLE [table2] (
[id] INTEGER NOT NULL ON CONFLICT FAIL PRIMARY KEY ON CONFLICT FAIL
AUTOINCREMENT,
[isActive] INTEGER NOT NULL ON CONFLICT FAIL DEFAULT
Hi,
I used to think that getting selected fields from a relational DB is faster
than getting all fields, so I used to carefully selected only those that I
needed for a particular task. However, this is time-consuming (for a
developer) and error prone. So, I've relaxed my rules on occasions. And

Hi,
SQLite probably was intended as an embedded database for standalone
software. However, because of its promotion by PHP community, it's been used
to power websites. I use it for that purpose too and prefer it over other
SQL DB solutions (primary because it allows me to move/backup data from a
