Hi,
I think a possible solution is to calculate the difference between
the database file size and the number of free pages multiplied by
the page size. This is of course an approximation, but it works for me.
Number of free pages: pragma freelist_count
Page size: pragma page_size

Hi,
I've got a question and I don't know exactly whether the behavior is
standard or expected or not.
Assuming the following schema and data:
CREATE TABLE t1 (id, name);
INSERT INTO t1 values (1, 'John');
INSERT INTO t1 values (2, 'Arnold');
INSERT INTO t1 values (3, 'Zork');

Unless ORDER BY is specified, the result of any SELECT is by definition
undefined. This undefined sort order has changed between previous versions

Correct.
SQLite (and all other SQL database engines) are free to return results
in whatever

I would change "might" in the previous sentence to "probably". ;-)

After experiencing some difficulty with comparing dates stored internally as
a floating point I was informed about the following.
"... due to the way floats are stored in computers, '=' isn't really a good
choice of an operator for them.
Instead of
Date = 38953.5890509
you should use

Because floating point numbers are an approximation you can enforce a
certain precision by calculating differences. You cannot use equality
with FP but you can decide that equality is when (A - B) < |N| where N

I'm not 100% sure but I think the answer is:
1,844,674,407,370,9551,615
which is an unsigned int (64bit).

Thanks for response.
I know the VACUUM is recovers the space left behind by deleting data from db
but this
is very expensive operator and it holds the locks for this database which will
be the big impact for other operations like inserting/updating the database.
I can read tye size of file in

Hi ,
I have two questions:
1) Calucate the actual size of the database(NOT RUN VACUUM) - "Actual
database size" which won't include the space of deleted rows.
To be more specific you calculate the database size by the following
below(WITHOUT VACUUM)
Database file size -

sqlite is serverless and does not have connections in the traditional
sense. The database is just a file and the number of programs that can
have the file open is dependent upon the operating system.

Is there a recommended way to save an in-memory database to a file? Is there
a way to access the underlying in-memory data directly to save out to disk
(if that would even work)?
My other thought was to create an empty file based db and attach it,
creating tables and transferring all the data

Well, an interesting illustration of basic sqlite; but no relation to the

Actually, it is a good answer to the question that was asked.
Running SQLite without a database file creates an
