Re: [sqlite] 3.6.20 NATURAL self-join still not fixed
Exactly my point. A few seconds is a LOT more than 0 seconds (I cancelled the query after a few seconds since it was obvious it did not do what it was supposed to). Just like in my first report, adding parentheses around the table name resolves this: sqlite> select count(*) from (test1) natural join (test1); 10 Present in both 3.6.19 and 3.6.20 (where it was fixed, according to the ticket).
