I'm using gcc (Ubuntu 5.4.0-6ubuntu1~16.04.10) 5.4.0 20160609
on 64 bit.
I have built both 64 and 32 bit versions from sqlite-src-324
No problems.
Check your build-essential install?

I'm curious if there is some standard or normal way to convert a SQLite DB to a
text representation, and then recreate the DB content from the text. Naively,
this seems hard or impossible as a general problem, but perhaps I am missing
something.

No UPSERT only works for uniqueness constraints (UNIQUE or PRIMARY KEY).

However, the parser silently discards the ON CONFLICT clause. I think
this has always been the case.
Well, I feel embarrassed, I have used this CHECK conflict clause a good
number of times

There is actually a way to do what you want. You do it with a TRIGGER which
does the test and drops the offending row using

By 'works fine' do you mean you didn't get a syntax error, or do you mean that
the clause actually does what you want, both to

Ok, thank you very much.
However, this is a bit confusing as e.g. this works fine:

May I suggest the appropriate extension for CHECK ON CONFLICT IGNORE or is
there a thoughtful

Yes. The ON CONFLICT clause goes in the INSERT command.
CREATE TABLE test (col1 TEXT CHECK (col1<>''));
Thank you, but I think there is a misunderstanding. I do want the constraint to
be checked, but I want to ignore the attempt to insert values that would
violate the check constraint.
According to the "on conflict" documentation

Hello,
Could you allow an outputting of autoreduced states when they produce
conflicts? I have noticed that such errors are caused by small and
hard-to-find remnants in a grammar file. There is no other way to detect
such errors. A few lines are getting the problem off (function

Because modulo bias. If the RHS doesn't evenly divide the size of the range of
RANDOM(), some results will be slightly more likely than others.

Thanks. We were up to date anyway, but we did check and we still get the

It does look like a compiler bug, also nobody else seems to have
reported it, which I think is very odd. I cannot be the first person to
compile this version of SQLite on Ubuntu 16.04 server.
As far as I know you have to purchase the documents.

I see Gunter already answered this for the specific case, I'll just add
some simple rules of thumb for transactions in general:
1. SQLite automagically starts a transaction ONLY when faced with a
single statement. The second statement in your query/list/script is in
its own transaction and

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
there's also nuget package for sqlite which handles updates pretty well.

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 "

WHERE key = 12
;
INSERT INTO testing
Same here. Again, I download it from the main system.data site. No problems
at all.
