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.

In cp932, '\' character can be the second byte in a

is really needed.

Item_int_with_ref::new_item, create the item by value, not by name.
This should work with prepared statements placeholders.
Item_int_with_ref is a special optimization case used
when we compare datetime constants with datetime value.
Converting the item to integer early is OK as it is in line
with the purpose of Item_int_with_ref - to speed up comparison by
using integers.

This fix changes equality evaluation method of basic constants from

keys for query).

Test results for the test case for Bug#9096
mysql-test/t/ps.test:
A short test case for Bug#9096 "select doesn't return all matched records if
prepared statements is used". The is enough to reproduce the
glitch in update_ref_and_keys causing the bug to occur.
sql/item.cc:
Implement by-value equality evaluation of basic constants.
This is needed to work with Item_param values. Until now
Item_param was compared with other items by its name, which is always "?".
The bug at hand showed up when an integer
constant was created from one parameter marker (with value 200887 and
name "?") and then compared by-name with another parameter marker
(with value 860 and name "?"). True returned by this comparison resulted
in a wrong table access method used to evaluate the query.
Implement Item_param methods needed to emulate "basic constant" mode at
full.
sql/item.h:
Change declaration of basic_const_item(): now it also widens its
argument from const Item * to Item * if the argument is a basic constant.
Declare eq() for all basic constatns, as long as now they
are compared by value, not by name. Each constant needs its own
comparison method.

a basic constant when parameter value is set.

The problem in 4.1 was the same as in 4.0 - fix_fields() not called for created Item_ref.
The fix is similar too - initialize Item_refs in ctor (but don't interfere with cases when
Item_ref is used by subselects).
