If, during your testing, you're using existing database files, please create
new ones each time.
Can you please publish your

That's surprising because the WAL logic does not have anything to do
with primary keys. Those are two completely independent
Dear SQL Developers / Users,
I am using Sqlite3 in our project. My database has journal_mode set to WAL and
has one writer & multiple readers. During normal mode of operation, only
writing process is accessing database and there is no active reader connection
I have observed that when I don't

I understand the risks and reasons, but have had numerous databases on our
Windows network accessed by 20+ users throughout the day without issue.
Thanks,

Hi All,
We are facing a problem in which sqlite library function sqlite3DbMallocRawNN()
is getting crashed inside the sqlite3_prepare_v2() function to prepare the
statement.
As per the analysis "n" value input to this seems to have a big value causing
the crash. checked the input value to

This sort of thing is almost always the result of heap corruption
Ok, now I understand. Thank you (and Richard) very much.

My guess on the requirement on the Parent Key needing a Unique Index is
that every insert into the child field needs to verify that there IS a
corresponding value in the parent key, and it would be SO inefficient
(in general) to need to do a full table scan to verify this, that it is
required to
May I ask why parent keys *must* have indexes? I don't see any correlation
between enforcing a client/parent-relationship and the necessity for an index.
I'm just asking to better understand. To me it is clear that the parent column
is to be declared as PRIMARY KEY or UNIQUE, but why does it
You do not need to define a column as UNIQUE and also put a UNIQUE INDEX on it.
create table a
(
b unique
);
is merely syntactic sugar for
create table a
(
b
);
create unique index sqlite_autoindex_a_1 on a (b);
so declaring something with a unique constraint on a column and also
I see. That version of the database is missing primary key option4_name...
Why did it suddenly start failing without the primary key index when it was
working for a very long time ...
it's almost like something removed the primary key
table|option4_name|CREATE TABLE `option4_name` (`name_id`
