Hi,
The manual states that the function julianday returns the number of days
since noon in Greenwich on November 24, 4714 B.C. That would imply that the
statement:

Should return 0.0. But it doesn't, it returns -365.0
Does this mean, that the manual

Hi,
Is there a possibility to open a SQLite database read-only so that

Thanks in advance.
Hi,
If I use the expression datetime('2000-01-01','1.5 months'), SQLite returns
2000-02-16 00:00:00. This means that it added one month plus half a month.
Makes sense.
If I use the expression datetime('2000-01-01','1.5 days'), I get 2000-01-02
12:00:00. Again this makes sense: 1.5 days is equal

Can confirm now that the method with INSERT OR REPLACE is faster indeed.
My timings tell me it is about twice as fast and that is worth it as that

I now wonder if there is an even faster way avoiding all the GROUP tables

There is one important problem though that I just discovered.

So, with my base table that is only 31 to add.

I'm not sure what "int()" does. Maybe you are looking for round().

I should also mention that I have been able to achieve what I want

Then I use this table in the join and sort on the autoincrement field:
