Hi,
Here is a version written in PL/SQL using StepSqlite
(https://www.metatranz.com/stepsqlite).
Perhaps it would be closest to what you expect: note how the variable
kwhcost is directly used in second query and also the StepSqlite
built-in date operators to simplify the query.

With SQLite, that's not really going to make a difference. Since it's a
In general, I think it's much better (performance and logic) to do all you can
in SQL, without passing values out of SQL results, into your non-SQL code, then
re-injecting back into another SQL query etc. Having said that, I'm not quite
sure why you are doing what you're doing, so I can't attemp

I read that page last night.. That sounded like what I wanted to do but I
had no idea how to get my simple query to be a parameterized query. That
is really what I was looking for help on.
select kwhcost1 from applications;
SELECT monitordata_hourly.deviceaddress,
Round(Sum(monitordata_hou

Yes - by using a subquery, as you were shown.

I was looking to store this whole query inside a view and just query the view
from outside sqlite.
Is there a way to inside a large sql statement to store a intermediate value
which could be used later in that query?

Read about parameterized queries:
http://www.sqlit
Store the results of the first query in a temporary table?

Yes, you use whatever p
I realize this works fine for this query but is there a way to to do this by
passing the results from one query to the second? I have some more complex
calculations coming up where I think this would be an easier way to go

I have a query the calcuates number of KWH and the cost of energy used in the
last 30 days. Right now the cost per KWH is hardcoded in the 2nd query at
.19. What I really want to do is get the value from
'select kwhcost1 from applications;' store that as a variable/paramter and
pass it into th
