You must have ISO8601 that has format
YYYY-MM-DD not YYYY/MM/DD. If you compare
strings it will not work. See result of
this query:

select date('now', '-1 days')

you get: 2017-08-23

Looks like it's me.

VBScript "NOW" = dd/mm/yyyy whereas ISO "NOW" = yyyy/mm/dd.

Doh!

Last part of the INSERT string reads:

       ,'" & strFreeSpace & "','" & pctFreeSpace & "','" & NOW & "');"

Changing it to:

       ,'" & strFreeSpace & "','" & pctFreeSpace & "', datetime('NOW') ); so
it inserts the SQLite 'NOW' instead.

See how well that works.  I need to update the other date/time stamps
though.

What you declare the field as doesn't matter, so much as what you actually
store in it. But all the functions apart from strftime use YYYY-MM-DD
HH:MM:SS so if you're giving them slashes and a different order then
they're all gonna mess up.

Correct:

SELECT strftime(date_time, -2) as iDATE from tmp_dspace_import


Result
21/08/2017 11:43:05
21/08/2017 11:43:05
21/08/2017 11:43:05
That's saying use date_time as the format string where -2 is the time
string. I'm surprised that actually gave an answer rather than an error.
And that you're getting a result with slashes is really really suspicious.


Then you can have query like this:

select date_time, servername, drive, sum(diff_used) DailyUsed_mb
from tmp_dspace_import
where date_time >= julianday(current_date) - 1
group by date_time, servername, drive

This would be for yesterday and today. If you need more days in past
then change expression: date_time >= julianday(current_date) - 1

Just yesterday is then: date_time = julianday(current_date) - 1

for two days back: date_time >= julianday(current_date) - 2

etc...
Don't forget that if you have a date and time in the database, then you're
comparing a whole time to just a day there. I think you'd want something
like

where date(date_time) = date(current_date, "-1 days")  --for yesterday
where date(date_time) >= date(current_date, "-6 days") --for within the
last week
where date(date_time) between date(current_date, "-3 days") and
date(current_date, "-1 days") --3 days ago to yesterday.
