6fc17dab1e Fixed bug #25427.
In the method Item_field::fix_fields we try to resolve the name of
the field against the names of the aliases that occur in the select
list. This is done by a call of the function find_item_in_list.
When this function finds several occurrences of the field name
it sends an error message to the error queue and returns 0.
Yet the code did not take into account that find_item_in_list
could return 0 and tried to dereference the returned value.

c095f98ff7 Bug #22457: Column alias in ORDER BY works, but not if in an expression
The parser is allocating Item_field for references by name in ORDER BY
 expressions. Such expressions however may point not only to Item_field 
 in the select list (or to a table column) but also to an arbitrary Item. 
 This causes Item_field::fix_fields to throw an error about missing 
 column.
 The fix substitutes Item_field for the reference with an Item_ref when 
 not pointing to Item_field.

3a0d0b4ce5 BUG#18492: mysqld reports ER_ILLEGAL_REFERENCE in --ps-protocol
In the code that converts IN predicates to EXISTS predicates it is changing
the select list elements to constant 1. Example :
SELECT ... FROM ...  WHERE a IN (SELECT c FROM ...)
is transformed to :
SELECT ... FROM ... WHERE EXISTS (SELECT 1 FROM ...  HAVING a = c)
However there can be no FROM clause in the IN subquery and it may not be
a simple select : SELECT ... FROM ... WHERE a IN (SELECT f(..) AS
c UNION SELECT ...) This query is transformed to : SELECT ... FROM ...
WHERE EXISTS (SELECT 1 FROM (SELECT f(..) AS c UNION SELECT ...)
x HAVING a = c) In the above query c in the HAVING clause is made to be
an Item_null_helper (a subclass of Item_ref) pointing to the real
Item_field (which is not referenced anywhere else in the query anymore).
This is done because Item_ref_null_helper collects information whether
there are NULL values in the result.  This is OK for directly executed
statements, because the Item_field pointed by the Item_null_helper is
already fixed when the transformation is done.  But when executed as
a prepared statement all the Item instances are "un-fixed" before the
recompilation of the prepared statement. So when the Item_null_helper
gets fixed it discovers that the Item_field it points to is not fixed
and issues an error.  The remedy is to keep the original select list
references when there are no tables in the FROM clause. So the above
becomes : SELECT ... FROM ...  WHERE EXISTS (SELECT c FROM (SELECT f(..)
AS c UNION SELECT ...) x HAVING a = c) In this way c is referenced
directly in the select list as well as by reference in the HAVING
clause. So it gets correctly fixed even with prepared statements.  And
since the Item_null_helper subclass of Item_ref_null_helper is not used
anywhere else it's taken out.

3190b21f95 Fix bug #14482 Wrongly applied optimization in resolve_const_item() caused
crash

resolve_const_item() substitutes item which will evaluate to constant with
equvalent constant item, basing on the item's result type. In this case
subselect was resolved as constant, and resolve_const_item() was substituting
it's result's Item_caches to Item_null. Later Item_cache's function was called
for Item_null object, which caused server crash.

resolve_const_item() now substitutes constants for items with 
result_type == ROW_RESULT only for Item_rows.

  We can't replace a ROW item with Item_null because:
  - Arg_comparator is still using the orignal row items and it's not good to have args[0] different from what is actually compared
  - If we are using the <=> comparator, NULL can still be compared as true
  - We would break things if we would ever use resolve_const_item() for operators like >, < etc.

  A test case for Bug#9379 (collation of a parameter marker is binary)
sql/item.cc:
  - set Item_param::collation to str_value collation, if Item_param
  is assigned a string. Reset it to default in Item_param::reset() (on 
  the next execution it can be assigned a number).
sql/item_func.cc:
  - now that item collation can change between executions
  (if this item is Item_param), we need to register the change
  of the execution tree in the rollback list.

ece17ba3cf - a fix for Bug#11458 "Prepared statement with subselects return random
data": remove the fix for another bug (8807) that
added OUTER_REF_TABLE_BIT to all subqueries that used a placeholder
to prevent their evaluation at prepare. As this bit hanged in 
Item_subselect::used_tables_cache for ever, a constant subquery with
a placeholder was never evaluated as such, which caused wrong 
choice of the execution plan for the statement.

831e2c7f61 Bug #7142 Show Fields from fails using Borland's dbExpress interface
The problem here is that columns that have an especially long type

as varchar(40).
