Of course, the correlated version returns all books, not just the ones that
have at least one author, were read at least once, and have at least one genre.

The current tip of trunk produced the same results demonstrated by Niklas in
his original post for his original testcase for me.

Instead of dropping ANALYZE information, did you try updating it instead, by
running ANALYZE again ?

Turns out that it happened due to the query planner decided to scan
sub-queries instead of using an automatic covering index to search them.
The database contains about 3000 entries and with two subqueries it

Yes sorry, it was a erroneous copy-paste. I was referring to
sqlite3_normalized_sql().
As Keith said, it’s only available if the SQLITE_ENABLE_NORMALIZE compile
option is used, but that is not documented anywhere.

Hi,
I have a database that used in software since probably 2010, there are many
variants of this database at my hd and everything was fine with it starting
3.6.10 through 3.26.00, I'm not sure about every version, but during the
version history, at least several was used to open it.
But 3.27.2 sa

All true. But even so, SQLite sho

For a start, do not use single quotes for table names. In SQL, DB object
identifiers can either be unquoted or contained in double-quotes. SQLite
specifically even allows backticks or square brackets for compatibility,
but nobody likes single quotes.
I.e. change this:
drop table 'fs_params_20

Be very careful of .sqlite2 files. The name suggests an obsolete version of
SQLite that is incompatible with everything from the last decade.
Apart from that, SQLite databases ca

A sqlite database is just a file. You can name it whatever you want. People
who like file extensions often use such ones (I assume you meant .sqlite2
and .sqlite3? The first would likely be used to indicate a sqlite 2
database, assuming you can find any software that still uses it...)

SQLite doesn't enforce types, but it does accept them.
They're documented at https://www.sqlite.org/datatype3.html
Basically, you want INTEGER and TEXT. There's no date type. I recommend
storing those as epoch integer, or in ISO text format, so that they're easy
to parse and sort correctly.
