Have in mind that storage class is not a 'type', it's more like an effective

Hi, do you have some news about the wasted memory? have you found the
reason for the windows backend?
do you think it could be due to the windows implementation of the mmap?

No, don't do that.

Folks,
I am trying to write an application that reads packets from the network and

Guess I'll do that. SQLite is just so convenient even from command line,

Because I'm writing glue code between the SQLite API and a higher level
library which provides a standard API across several DBMSs.
In other DBMSs even if a field contains null you can still ask the API
what type it 'should' have been if something *had* been put in it.

Hi everyone,
My C program has a CREATE TRIGGER statement which contains a template "?":
CREATE TABLE employees (
employee_id INTEGER PRIMARY KEY,
dep_id TINYINT,

);

INSERT ON employees

No. I use sqlite in proprietary application, not the shell!
I use cegcc to compile sqlite.
