I requested information about where this project is maintained and by whom.
Any response appreciated.

No.
If you are going to make lots of changes to the table and rarely use SELECT, do
the calculation in the SELECT command.
If you are going to make few changes to the table but do lots of searching and
sorting,
Before checkpointing the data from WAL, if the DB is queried, will the
result include updated data from WAL or not?
Will this situation arise? because writing to WAL and checkpoint occur very
fast but if a query comes in between, will the result be updated or not
before checkpoint.

It will. A transaction reads both from WAL and the original database
file - whichever contains the fresher data.

In case you're new to this group, please understand that I'm experienced with
SQLite and I understand how it works and how it uses journal files.
Can someone explain to me -- or point at a web page which does -- why a
separate journal file is needed. Why can't the information which SQLite

In a join, you can directly use a subquery with multiple columns:
... JOIN (SELECT ...) ...

Hello Everyone,
I have two unrelated tables table_A and table_B in my SQLite DB. Trying to
drop table_B while a resultset is open on table_A throws
"java.sql.SQLException: database table is locked".
Following simple code will illustrate the Bug clearly.

SQLite does not have table-level locking. If anything in the database file
needs to be locked then the whole

Doing so would double the size of the database file. Every database
file would contain extra space (normally unused) set aside for the
journal.

Good point!
I can assume that the problem would be a sparsity of database file. If you mix
normal pages and journal then database will be fragmented.
You can't avoid it. Even if you start writing journal at the end of file,
hoping that you can later truncate it at commit, there is no way to

IMO, all that, plus the fact that you have an easy roll back mechanism.
Anything that needs to be put in the database is external to the pristine
database. Lock the database with a transaction, fill up the journal, the
power goes out, your pristine database isn't touched. Just whatever
happens

That's an SQLITE_LOCKED error. Here:

Deadlock detection, I would guess. See

Dan deduced that you must be using -DSQLITE_OMIT_BLOB_LITERAL. That
(unsupported) compile-time option does indeed induce the error you are

Hi Richard,
that was really fast!
Indeed, I was using the SQLITE_OMIT_BLOB_LITERAL flag.
Removing the flag solved the issue.
Thank you guys for a quick solution.

Hello !
I have a modification on the parser.y for my own purposes and it was been
parsed till the introduction of " /*A-overwrites-S*/" and it seems that
something is wrong on parser.y see bellow, after the SELECT specification the
" /*A-overwrites-S*/" is wrapped by "#if SELECTTRACE_ENABLED"
Here is the full changes I did in parser.y:
?
%endif SQLITE_OMIT_COMPOUND_SELECT
oneselect(A) ::= SELECT|XSELECT(S) distinct(D) selcollist(W) from(X)
where_opt(Y)
groupby_opt(P) having_opt(Q) orderby_opt(Z)
limit_opt(L). {
#if SELECTTRACE_ENABLED
? Token s = S;
I solved it setting a variable before " /*A-overwrites-S*/", but I's still
confusing it's usage inside a wrapped "#ifdef" that supposed only will be
executed conditionally.
Cheers !

Hi,
We run into a reproducible crash on FTS5 search when searching something
complex such as:
"(word1* word2* word3*) OR word1* OR word2* OR word3*"
It might be that we are doing something wrong, but any insight is appreciated.
The actual crashing call is a sqlite3_step/1 call:
while
You would need some sort of allocation table for the journal (wal or
rollback) and on a rollback commit or a wal checkpoint the allocation
would need to be cleared (or maybe some "in use" bit cleared) to show
that the pages were now free to be re-used.
The additional data stored with rollback
