Hi All!
A feature I'm missing is a syntax like with insert or update.
You define a table as:
create table table_test (id as integer primary key, a as integer, b as
integer, c as integer)
Then you know that the id is unique and you only can have one row with
that integer.
Then you can give the
You can check the number of rows modified by an UPDATE statement using the
sqlite3_changes() interface. (Using pragma count_changes is deprecated!)
Within a transaction, when you issue an
UPDATE table_test SET field=value WHERE id = key;
and sqlite3_changes() returns 0 then you need to
INSERT
Which circumstances are you thinking of that would cause the proposed
insert or update to fail (other than those that would cause the update
to fail too)?
It is a fail condition when the statement is ambiguous.

integer, c

It's not as if it is a hard thing to do, I continuously run update algorithms

Insert into table_test (a,b) values (1,2); inserts a new row with a default id

Update table_test set a=1, b=2; modifies all rows of the table and does not
fail either.
Why should insert or update fail???

You are right it won't fail if you define the table with autoincrement:
create table table_test (id as integer primary key AUTOINCREMENT, a as
integer, b as integer, c as integer)

Hi,
We've observed a severe performance regression in a query.
We had a query Q1, which was running fast, on 3.7.15.2. We made a minor change
to the query, which we'll call Q2.
Q2 runs excruciatingly slowly in 3.7.15.2 (1m 28sec). We then observed that Q2
was fast in 3.7.14 (300ms), but slow

We cannot accept your patch anyhow, unless you have a Contributor License
Agreement on file. To do otherwise
Thank you for your suggestion!
I would like to have all in one statement, then insert or update is
perfect. This is least error prone. If you split the statement into
several, you will end up in more statements to test and more bugs. (You
write 3 on two places.)
Working with blobs, I expect this
Use parameters and bind...
REPLACE INTO table_test
SELECT :key, a, b, :val FROM table_test WHERE id=:key
UNION ALL
SELECT :key, NULL, NULL, :val

I believe the performance of my current statements is better and clearer.
Now I'm doing: insert or ignore into table_test (id) values (1) and
then issue an update statement. I think insert or update will
increase performance.
Although I'm not happy with it.

No, there isn't. I just copy/pasted the insert out of my long script.
Insert 1 to 472 works well, #473 was just the first one that fails. Hm,

OK, I tried the SQLite command line tool 3.7.17 and inserted all 1 million
records without any error. Then I cleared the table, ran the same SQL again
in SQLite Studio and *bang* same error. Seems to be a problem of SQLite
Studio. Anyway, I'm glad thats no bug in SQLite and my problem is solved.
