You are right. Id however is presumed to be related to what is being averaged
over, not a rowid. One would presume that the simple integers are just "demo
values" and that in actual fact it contains a Modified Julian Date. If it does
not contain an "offset in days from some base value" then
The inner query is called a correlated subquery. The query in ( ... ) is
executed for each row of the outer query. Correlated means that a value from
the "outer query" is used to constrain (in a where condition) the rows used
when computing the scalar result of the subquery.

The new VSIX package for Visual Studio 2012 contains a build of
SQLite for WinRT on ARM.
Please look for the "sqlite-winrt-3071300.vsix" file in the
"Precompiled Binaries for Windows Runtime" on the page:
http://www.sqlite.org/download.html
Alternatively, it may be downloaded while insi

1) s/MAXINT/INT64_MAX/;
2) it is rather inefficient;
3) it will break on ID discontinuity; and
Hi all,
it is great to have the WinRT compliant version of SQLite, good work!! Now one
last thing missing is the WinRT / ARM version.
It is possible right now without bigger modifications:

You are right Klaas, it should be -2 not -3. You could always constrain id to
(MAXINT >= id >= 3-MAXINT) if you wanted to be sure there would not be an
arithmetic overflow.
