After executing the following:

res = sqlite3_step( stmt );
if( res == SQLITE_ROW )
{
// process the record
}
else if( res == SQLITE_DONE )
break;

The problem not having a DATETIME field is, however, very simple: When
reading a foreign database which stores date values as a number, I
have to guess on how to get back the correct date.
The datatype used is irrelevant w.r.t. this issue. Unless fully
qualified with convention used and
Not even Microsoft Excel has a dedicated datetime/timestamp type. It is just a
presentation layer attribute of a floating point value. Also, you get to choose
the way you want calendar data to be stored. So why?

This does not make sense without an ORDER BY.

No.
Hi all,
