      Fixed bug#16302: Quantified subquery without any tables gives wrong results · ad88eabd
      unknown authored
      The ALL/ANY subqueries are the subject of MIN/MAX optimization. The matter
      of this optimization is to embed MIN() or MAX() function into the subquery
      in order to get only one row by which we can tell whether the expression
      with ALL/ANY subquery is true or false.
      But when it is applied to a subquery like 'select a_constant' the reported bug
      occurs. As no tables are specified in the subquery the do_select() function 
      isn't called for the optimized subquery and thus no values have been added 
      to a MIN()/MAX() function and it returns NULL instead of a_constant.
      This leads to a wrong query result.
      
      For the subquery like 'select a_constant' there is no reason to apply
      MIN/MAX optimization because the subquery anyway will return at most one row.
      Thus the Item_maxmin_subselect class is more appropriate for handling such
      subqueries.
      
      The Item_in_subselect::single_value_transformer() function now checks
      whether tables are specified for the subquery. If no then this subselect is
      handled like a UNION using an Item_maxmin_subselect object.

      Bug#11228: DESC shows arbitrary column as "PRI" · 89e41595
      unknown authored
        An UNIQUE KEY consisting of NOT NULL columns
        was displayed as PRIMARY KEY in "DESC t1".
        According to the code, that was intentional
        behaviour for some reasons unknown to me.
        This code was written before bitkeeper time,
        so I cannot check who and why made this.
        After discussing on dev-public, a decision
        was made to remove this code

      Fixed bug #14896. · 822e8866
      unknown authored
      This bug in Field_string::cmp resulted in a wrong comparison 
      with keys in partial indexes over multi-byte character fields.
      Given field a is declared as a varchar(16) collate utf8_unicode_ci
      INDEX(a(4)) gives us an example of such an index.
        
      Wrong key comparisons could lead to wrong result sets if 
      the selected query execution plan used a range scan by 
      a partial index over a utf8 character field.
      This also caused wrong results in many other cases.

      BUG#20357 - Got error 124 from storage engine using MIN and MAX · 5c0cdea6
      unknown authored
                  functions in queries
      
      Using MAX()/MIN() on table with disabled indexes (by ALTER TABLE)
      results in error 124 (wrong index) from storage engine.
      
      The problem was that optimizer use disabled index to optimize
      MAX()/MIN(). Normally it must skip disabled index and perform
      table scan.
      
      This patch skips disabled indexes for min/max optimization.

      * Bug #9676: INSERT INTO x SELECT .. FROM x LIMIT 1; slows down with big · 124cb126
      unknown authored
                    tables
      Currently in INSERT ... SELECT ... LIMIT ... the compiler uses a 
      temporary table to store the results of SELECT ... LIMIT .. and then
      uses that table as a source for INSERT. The problem is that in some cases
      it actually skips the LIMIT clause in doing that and materializes the 
      whole SELECT result set regardless of the LIMIT.
      This fix is limiting the process of filling up the temp table with only 
      that much rows that will be actually used by propagating the LIMIT value.

      BUG#18036 - update of table joined to self reports table as crashed · 46cdd39e
      unknown authored
      Certain updates of table joined to self results in unexpected
      behavior.
      
      The problem was that record cache was mistakenly enabled for
      self-joined table updates. Normally record cache must be disabled
      for such updates.
      
      Fixed wrong condition in code that determines whether to use
      record cache for self-joined table updates.
      
      Only MyISAM tables were affected.
