Not correct (fully) - the CTime class does have this limit, but not
COleDateTime (quote from MSDN: "The COleDateTime class handles dates

For comparison it's best to use GetYear(),

You could certainly store the float date as a float type field

Hi,
Does SQLite's sqlite_exec_printf function accept length modifiers, like
printf from stdio does?
It doesn't seem like it does, which is bad for me who want to insert 64
bit integers (using the ll modifier).
If it doesn't, any other idea of how I can convert 64 bit integers to
strings before
I have a query which calculates the number of events during an hour by the

You can use SQLite for this purpose (instead of C) as described in

Hi Dave,
Wrap your update and select inside a transaction - the transaction is atomic
in this regard and locks the table after the update and doesn't let it go
until the commit/rollback. Others can read (they get the uncommitted values
of course) but can't update. You will always get the latest

Hello,
two questions:
1.
SELECT TYPEOF(ROUND(1));
... returns 'text'. Is it OK? Sorry, I asked this question 2 days ago but I
still don't know - is it a bug or not?
2.
sqlite> CREATE TABLE test(id INTEGER NOT NULL PRIMARY KEY UNIQUE, fld
INTEGER);
sqlite> INSERT INTO test(fld) VALUES(1);
I submitted a bug report about it, where I also explained how to work
around this problem.
