Also, I tried to replace the very large time value to a small enough one,
3. select max(time) from mytable where time < 0 and id1=k1 and id2=n
This query also run very fast.
Could anyone explain this to me? Thanks in advance.

Hi, List
I found my sqlite application presents a huge VSZ usage, 100+M in an
ARM system, which has only 128M physical memory. Does this because
sqlite is using mmap to map the database file? If this is the reason,
how can I reduce the VSZ used?

Hi,
I want to omits the Sqlite's internal invocation of malloc(3). What I

Thanks for the clear guide. _busy_timeout is easier to use. By the way, i
want confirm that if i am not in an explicit transaction, i can simply redo
the _step() invoking, right?

Hi,
The manual says that it should to rollback after sqlite3_step() returns
SQLITE_BUSY as long as
the current statment is in a transaction. Is this true? Why I cannot just
sleep for a while
and redo the sqlite3_step()?
Thanks in advance.

n my ode, then I can fixed. But if my code is okay, it's really
a big probleme. If, otherwise, someone can confirm that this is a sqlite
bug,
can I have any work-around?
Thanks in advance.

I've read the doc, it's not so easy to understand.
Did you mean, in number(N),
I have an old dabase, some integer columns were defined as type of
number(2). What does this mean in sqlite3? What's the data ragne it
can represent, and how much bytes it will consume when stored?
Thanks in advance.

'? Especially, is that possible that the 'commit' could get
an error of SQLITE_BUSY? You know, the reason I want to use exclusive
transaction is to simplify the programming.
Thanks in advance.

if this is caused by sqlite or Yaffs2 itself, on the other hand, I
also cannot prove this really means bad things since the program at that
moment was still running fine.

Hi,
I am considering to use SQLite in my current embedded application
project. It's a ARM9/Linux. Do you experts think it is a good idea？
And, is there any tips or considerations in this combination?
Thank you.
