I think i used a wrong version of "libmysql.dll". So sry. :D

=============================================================================


Sorry for my English.

I got the same problem with this topic:
http://forums.mysql.com/read.php?167,298946,298946

First, the placeholder syntax seem not work:

Code:
==========================================================================
pstmt = con->prepareStatement("INSERT INTO test(id) VALUES (?)");
for (int i = 1; i <= 10; i++) {
pstmt->setInt(1, i);
pstmt->executeUpdate();
}
==========================================================================

All of id values are 0. I think they should be 1 to 10.

And the second is result of:

Code:
==========================================================================
/* Select in ascending order */
pstmt = con->prepareStatement("SELECT id FROM test ORDER BY id ASC");
res = pstmt->executeQuery();

/* Fetch in reverse = descending order! */
res->afterLast();
while (res->previous())
cout << "\t... MySQL counts: " << res->getInt("id") << endl;
==========================================================================

I got 10 of -1163005939 values instead 10 to 1.

I don't know why the topic above had no reply and was locked. I'm new of SQL and my English is bad, but please help me.

Thank you.
