I was thinking that, but was not sure. I thought that maybe everything in
a call would be seen as a transaction. But that is not the case then: every
statement in a call is its own transac
there's also nuget package for sqlite which handles updates pretty well.

Why should a failure in transaction #2 rollback transaction #1?
If you want this behaviour, do "begin; delete ...; insert ... on conflict
rollback; commit;" to make both statements run in one transaction

I am working with Tcl. The best is of-course a general answer, but if it is
depending on the used language I will be satisfied with the Tcl answer. ;-)
Say I have the following code:
set SQLCmd "
DELETE FROM testing
WHERE key = 12
;
INSERT INTO testing
Same here. Again, I download it from the main system.data site. No problems
at all.

I use system.data.sqlite.dll (taken from here:
https://system.data.sqlite.org/index.html/doc/trunk/www/downloads.wiki)
with no problems in both VS 2017 Professional and VS 2017 Community.
Thanks,

Thanks for providing a succinct test case! A fix is now check-in on
trunk. https://www.sqlite.org/src/info/164b1641e346994f
Just FYI, the regression test case was added to TH3
(https://www.sqlite.org/th3.html) rather than in the main source tree
as it is much easier to incorporate there.

I am considering using the .net version of SQLite but have two questions:
1. The documentation lists the versions of Visual Studio that are
supported. VS2017 is NOT listed. Is VS2017 supported.
2. The documentation states "Due to Visual Studio licensing
restrictions, the Express Editions

It segfaults. If the first argument is 3 or 4 it also segfaults.

I found a missing sqlite_reset call in my wrapper library, and the
solution proposed by Richard works great. So does the solution of
guarding all the sql execute calls with a mutex. I have to perform the
speed tests for the expected dataset and thread count yet. Thank you
for your help!

Apologies. In SQLite this should be
(RANDOM() % 7)
instead. The percent sign is a 'modulo' operator.

Don't divide by a number like 1.4e18 in an 18-digit INTEGER calculation and
expect to get sensible answers.
Use the conventional
CAST(RANDOM() * 7) AS INTEGER
or whatever spread you want.

OK, thanks. Something to look into at a later moment.

You probably do not have the kurtosis or skew aggregate functions either.
generate_series is the series.c extension.

A long time ago I changed a line base application to a SQLite application.
Every line was a record and this record could have several elements. Every
element was send to Twitter with a minute between them. When converting I
kept it like this. So my SQLite database contains for example:
"5BF19111-9F

stop=1e6;

stop=1e6;
0.00104535938599554
The PRNG is pretty random.
It is slightly concave (that is, anti-normal) (a "
