Hello,
I am very new database development and sqlite. I have a requirement
where I want to restrict the size of my integer primary key to 3 bytes.
In my database, entries will be added and removed very frequently. So If the
primary key limit of 3 bytes is reached, it should try to reuse the
Since it apperas you're running your commit in a separate thread and are
therefore muilti-threaded I do belive you need:
SQLITE3_THREADSAFE=2
From http://www.sqlite.org/compile.html#threadsafe
To put it another way, SQLITE_THREADSAFE=1 sets the default threading mode to
Serialized.

All I need to do is see how many rows a table has. I stumbled across this
function and used it thusly in my code (I removed the error checking for the
sake of brevity):
Result = sqlite3_initialize();
sqlite3 *db_ptr;
Result = 0;
Result = sqlite3_open_v2(DBEnginePath, db_ptr,
BTW, if there is a better way to get a row count without using
sqlite3_get_table() that would also work.

maybe I am missing something, but what is wrong with SELECT Count(*) FROM
table?

Hi,
When sqlite3_step() fail because a UNIQUE constraint is not satisfied,
it returns SQLITE_ERROR.
I see that there is an error code named SQLITE_CONSTRAINT. Why
sqlite3_step() does not return this one?
Having a specific error code would be useful to warn the user that the
data he submitted

at the bottom.
I believe it was changed with recent versions of SQLite. Is call to
sqlite3_extended_result_codes
(http://www.sqlite.org/c3ref/extended_result_codes.html) not needed
anymore?

I have tried the latest Explorer and it gets a syntax error on STDEV.
However, that function works in Eclipse just fine, to take the standard
deviation of a column (like min, max, avg). Is there a workaround or
other fix available? Explorer doesn't recognize VAR or VARIANCE
either. I tried
