ec3de56263 Fixed bug #27348.
If a set function with a outer reference s(outer_ref) cannot be aggregated 
the outer query against which the reference has been resolved then MySQL
interpretes s(outer_ref) in the same way as it would interpret s(const).
Hovever the standard requires throwing an error in this situation.
Added some code to support this requirement in ansi mode.
Corrected another minor bug in Item_sum::check_sum_func.

1f8bdbe4eb Fixed bug #27229: crash when a set function aggregated in outer
context was used as an argument of GROUP_CONCAT.
Ensured correct setting of the depended_from field in references
generated for set functions aggregated in outer selects.
A wrong value of this field resulted in wrong maps returned by 
used_tables() for these references.
Made sure that a temporary table field is added for any set function
aggregated in outer context when creation of a temporary table is 
needed to execute the inner subquery.

  Added a method that says whether a set function is aggregated

  Removed the field nest_level_tables_count introduced by the

  sane number.

91f7f31816 Fixed bug #27257: queries containing subqueries with COUNT(*)
aggregated in outer context returned wrong results.
This happened only if the subquery did not contain any references
to outer fields.
As there were no references to outer fields the subquery erroneously
was taken for non-correlated one.
Now any set function aggregated in outer context makes the subquery
correlated.

91abf15ed2 Fixed bug #26738: incomplete string values in a result set column
when the column is to be read from a derived table column which 
was specified as a concatenation of string literals.
The bug happened because the Item_string::append did not adjust the
value of Item_string::max_length. As a result of it the temporary 
table column  defined to store the concatenation of literals was 
not wide enough to hold the whole value.

a1e20e04d8 Bug#21904 (parser problem when using IN with a double "(())")
Before this fix, a IN predicate of the form: "IN (( subselect ))", with two
parenthesis, would be evaluated as a single row subselect: if the subselect
returns more that 1 row, the statement would fail.

The SQL:2003 standard defines a special exception in the specification,
and mandates that this particular form of IN predicate shall be equivalent
to "IN ( subselect )", which involves a table subquery and works with more
than 1 row.

This fix implements "IN (( subselect ))", "IN ((( subselect )))" etc
as per the SQL:2003 requirement.

All the details related to the implementation of this change have been
commented in the code, and the relevant sections of the SQL:2003 spec
are given for reference, so they are not repeated here.

Having access to the spec is a requirement to review in depth this patch.

33446269e1 Fixed bug #24670: optimizations that are legal only for subqueries without tables

  Added a test case for bug #24670.
sql/item_subselect.cc:
  Fixed bug #24670: optimizations that are legal only for subqueries without tables
  and no WHERE condition were applied for any subquery without tables.
  
  Removed an assertion that caused an abort for subqueries without tables and no 
  WHERE condition. 
  Blocked substitution of a single-row subquery without tables for the constant 
  row from its select list when the subquery contained a WHERE condition.
  This optimization is valid only for subquries without tables with no conditions.
  Any subquery without tables with WHERE clause returns NULL if the WHERE condition
  is FALSE. Erroneously it was always considered as non-nullable that could trigger 
  another optimization concerning IS NULL predicates which is applicable only for 
  non-nullable expressions and ultimately led to a wrong result returned by the outer
  query.
  Added a proper implementation of the virtual method may_be_null for class 
  subselect_single_select_engine.
sql/item_subselect.h:
  Fixed bug #24670: optimizations that are legal only for subqueries without tables
  and no WHERE condition were applied for any subquery without tables.
  Made method may_by_null for class subselect_engine vvirtual.

5af4fd2563 Bug #11032: getObject() returns a String for a sub-query of type datetime
- When returning metadata for scalar subqueries the actual type of the
   column was calculated based on the value type, which limits the actual
   type of a scalar subselect to the set of (currently) 3 basic types : 
   integer, double precision or string. This is the reason that columns
   of types other then the basic ones (e.g. date/time) are reported as
   being of the corresponding basic type.
   Fixed by storing/returning information for the column type in addition
   to the result type.

2a7cf59fc9 Fixed bug #21727.
This is a performance issue for queries with subqueries evaluation
of which requires filesort.
Allocation of memory for the sort buffer at each evaluation of a
subquery may take a significant amount of time if the buffer is rather big.
With the fix we allocate the buffer at the first evaluation of the
subquery and reuse it at each subsequent evaluation.

841ea461ce Bug#21798: memory leak during query execution with subquery in column
list using a function
When executing dependent subqueries they are re-inited and re-exec() for 
each row of the outer context.
The cause for the bug is that during subquery reinitialization/re-execution,
the optimizer reallocates JOIN::join_tab, JOIN::table in make_simple_join()
and the local variable in 'sortorder' in create_sort_index(), which is
allocated by make_unireg_sortorder().
Care must be taken not to allocate anything into the thread's memory pool
while re-initializing query plan structures between subquery re-executions.
All such items mush be cached and reused because the thread's memory pool
is freed at the end of the whole query.
Note that they must be cached and reused even for queries that are not 
otherwise cacheable because otherwise it will grow the thread's memory 
pool every time a cacheable query is re-executed. 
We provide additional members to the JOIN structure to store references 
to the items that need to be cached.

  Bug #21540: Subqueries with no from and aggregate functions return
              wrong results
   Mark the containing Item (Item_subselect descendant usually) of 
   a subselect as containing aggregate functions if it has references
   to aggregates functions that are calculated outside its context.
   This tels end_send_group() not to make an Item_subselect descendant in
   select list a copy and causes the correct value being returned.

c9bba13aee Bug#14654 : Cannot select from the same table twice within a UNION statement
Made the parser to support parenthesis around UNION branches.
 This is done by amending the rules of the parser so it generates the correct
 structure.
 Currently it supports arbitrary subquery/join/parenthesis operations in the 
 EXISTS clause. 
 In the IN/scalar subquery case it will allow adding nested parenthesis only 
 if there is an UNION clause after the parenthesis. Otherwise it will just  
 treat the multiple nested parenthesis as a scalar expression.
 It adds extra lex level for ((SELECT ...) UNION ...) to accommodate for the
 UNION clause.

109615048d Fixed bug #20869.
The bug caused a crash of the server if a subquery with
ORDER BY DESC used the range access method.
The bug happened because the method QUICK_SELECT_DESC::reset
was not reworked after MRR interface had been introduced.

203d46bb38 Fixed bug #20519.
The bug was due to a loss happened during a refactoring made
on May 30 2005 that modified the function JOIN::reinit.
As a result of it for any subquery the value of offset_limit_cnt
was not restored for the following executions. Yet the first 
execution of the subquery made it equal to 0.
The fix restores this value in the function JOIN::reinit.

d2bbf288a9 Fixed bug#18503: Queries with a quantified subquery returning empty set
may return a wrong result.

An Item_sum_hybrid object has the was_values flag which indicates whether any
values were added to the sum function. By default it is set to true and reset
to false on any no_rows_in_result() call. This method is called only in
return_zero_rows() function. An ALL/ANY subquery can be optimized by MIN/MAX
optimization. The was_values flag is used to indicate whether the subquery
has returned at least one row. This bug occurs because return_zero_rows() is
called only when we know that the select will return zero rows before
starting any scans but often such information is not known.
In the reported case the return_zero_rows() function is not called and
the was_values flag is not reset to false and yet the subquery return no rows
Item_func_not_all and Item_func_nop_all functions return a wrong
comparison result.

The end_send_group() function now calls no_rows_in_result() for each item
in the fields_list if there is no rows were found for the (sub)query.
