Hi,
I've created a view that is a union of two tables. How can I enable FTS for
this view?
Since views don't have a "rowid" I'm unable to populate the FTS virtual
table with the contents of the view.
Is there a workaround for this?
Thank you!

Of course, what we are emulating here is called a "Process Historian", common
examples being PHD and PI. So, if you make a few minor adjustments, you can
make this run just about as fast as a "designed for purpose" Process Historian.
The changes are that you need to store the data in an
This will get you the consumption projection for each day in the table
(timestamp in s represents the ENDING period you are interested in and you can
modify it to whatever interval you want, and of course the final query gets the
result). It works by computing the slope from each timestamp to
As far I have ended with following:
WITH miniPow as (
select date(TIMESTAMP,'+1 day') as d, max(TOTAL_KWH) mini
from power
group by date(timestamp)
)
, maxiPow as (
select date(TIMESTAMP) as d, max(TOTAL_KWH) maxi
from power
group by date(timestamp)
)
select maxiPow.d, ROUND(maxi-mini, 1) from

Thank you both for your quick and helpful replies! The `quirks.html`
page certainly clears things up. Glad to see that there are new options
to disable this; I reached out to the maintainers of the language
bindings that I use to see if we can get that enabled [1].

Thank you Keith for your answer. It has led me to more questions.
"though you may or may not have visited all rows"
From the documentation I did not get the impression that you would ever not
visit ALL ROWS at least once. Is there a technical reason for this? I would
assume a full table scan is

This problematic behavior, including discussion on how to disable it, is
documented here: https://www.sqlite.org/quirks.html#dblquote
I tracked down a perplexing issue to the following behavior:
sqlite> CREATE TABLE tab (col);
sqlite> SELECT nope FROM tab; -- fails; good
Error: no such column: nope
sqlite> SELECT "nope" FROM tab; -- works?
sqlite> INSERT INTO tab (col) VALUES (77);
sqlite> SELECT col
