sqlite is file-based. use your filesystems quota functionality.

I want to put a limit like 10mb then later on e able to change this
database limit
to 15mb if I want to, is this possible?
You could use auto_vacuum (so the data file shrinks when data is
deleted) and check the file size so you know when it is "full."

Hello,
I recently had some troubles converting a database from v2.8.0 to v3.08
per the following commands (under Windows XP):
sqlite ddg53.db .dump >ddg53.dump
sqlite3 ddg53.db3 ".read ddg53.dump"
The dump of the 2.8.0 database did not enclose varchar fields containing
numbers with

Wait - what if AUTOVACUUM is set on the database, and I'm the only one doing
inserts/deletes? Will I still need to sqlite3_prepare() my statements again
if auto-vacuum is on?

Stop inserting when it's full?
Sorry to bombard with so much email.
A small request for later version of SQLite.
Would it be possible to change this error message:
"logic error or missing database"
To:
"logic error, missing database, database read-only, or database
directory read-only."
I hope this is not unreasonable,

It looks like I didn't look before leaping. MySQL does do a
I have a problem with SQLite locking when trying to allocate memory. I
don't know whether this is my problem, or something else. But the
problem occurs inside SQLite.
A backtrack shows:
/usr/local/lib/libsqlite3.so.0(sqlite3ParserAlloc+0x26) [0x4013d1c6]
Is that statement correct Richard?

bonnet they got translated into UNION statements or similar.

I would like to know if there is a way to limit a sqlite database and then be
able
to change this limit later on?
Won't work unfortunately. Currently indices are never used if
the WHERE clause has an OR expression in it.

Does that help?

I am new in the world sqlite.
I was on the site and I looked at how to make to begin thanks to the

I thus compiled the sources of sqlite 3.2.2.

I have to create a table "personne" and I added data there.

Thanks for the advise, I will alter my program.
Do you know which compilers do need this treatment? (I am using GCC 3.3.3).
