Changes

  1. foundin changed to: "3.7.16-alpha"
  2. icomment:
    The following script gives an error on the SELECT statement:
    
    <blockquote><verbatim>
    CREATE TABLE t1 (a INTEGER PRIMARY KEY);
    CREATE TABLE t2 (a INTEGER PRIMARY KEY, b INTEGER);
    CREATE TABLE t2x (b INTEGER PRIMARY KEY);
    SELECT t1.a FROM ((t1 JOIN t2 ON t1.a=t2.a) AS x JOIN t2x ON x.b=t2x.b) as y;
    </verbatim></blockquote>
    
    The error only occurs if the name of the third table includes the name
    of the second table as a prefix.  This problem was introduced by
    check-in [99127a669c] on 2013-01-03 and has never appeared in an official
    release.
