The problem was that some functions (namely IN() starting with 4.1, and
CHAR() starting with 5.0) were returning NULL in certain conditions,
while they didn't set their maybe_null flag. Because of that there could
be some problems with 'IS NULL' check, and statements that depend on the
function value domain, like CREATE TABLE t1 SELECT 1 IN (2, NULL);.
The fix is to set maybe_null correctly.
mysql-test/r/func_in.result:
Add result for bug#17047: CHAR() and IN() can return NULL without
signaling NULL result.
mysql-test/t/func_in.test:
Add test case for bug#17047: CHAR() and IN() can return NULL without
signaling NULL result.
sql/item_cmpfunc.cc:
Remove assignment to maybe_null, as it was already set in fix_fields()
based on all arguments, not only on the first.
Evaluate "NULL IN (SELECT ...)" in a special way: Disable pushed-down
conditions and their "consequences":
= Do full table scans instead of unique_[index_subquery] lookups.
= Change appropriate "ref_or_null" accesses to full table scans in
subquery's joins.
Also cache value of NULL IN (SELECT ...) if the SELECT is not correlated
wrt any upper select.

BUG#8804: wrong results for NULL IN (SELECT ...):
- When needed, wrap the predicates we push into subquery into an

NULL IN (SELECT ...).
- Added code to evaluate NULL IN (SELECT ...) in a special way:
= In [unique_]index_subquery, do full table scan to see if there
are any rows.
= For other subqueries, change ref[_or_null] to ALL if the
ref[_or_null] was created from pushed-down predicate.

an argument of a comparison predicate.

Added a method to check whether a field reference can be
substituted for a constant equal to the field.
This substitution is allowed if the field is not of a type string
or if the field reference serves as an argument of a comparison
predicate.
sql/item.h:
Fixed bug #21698.
Added a new virtual transformation method for a item 'compile'
with two callback function parameters.
Added a new virtual method 'subst_argument_checker' to be used
as an amnalyzer method.
This method is supposed to set its in/out argument to NULL for
the nodes where substitution of a string field for a constant
is not valid.
sql/item_cmpfunc.cc:
Fixed bug #21698.
Added an implementation of the compile method for class Item_cond.
First it processes the Item_cond node with a callback function and if

A date can be represented as an int (like 20060101) and as a string (like
"2006.01.01"). When a DATE/TIME field is compared in one SELECT against both
representations the constant propagation mechanism leads to comparison
of DATE as a string and DATE as an int. In this example it compares 2006 and
20060101 integers. Obviously it fails comparison although they represents the
same date.
Now the Item_bool_func2::fix_length_and_dec() function sets the comparison
context for items being compared. I.e. if items compared as strings the
comparison context is STRING.
The constant propagation mechanism now doesn't mix items used in different
comparison contexts. The context check is done in the
Item_field::equal_fields_propagator() and in the change_cond_ref_to_const()
functions.
Also the better fix for bug 21159 is introduced.

This bug is a side-effect of bug fix#16377. NOW() is optimized in
BETWEEN to integer constants to speed up query execution. When view is being
created it saves already modified query and thus becomes wrong.

for their results only if the current query isn't CREATE VIEW or SHOW CREATE
VIEW.

Two functions have different ideas of what a string should look like;
one of them reads memory it assumes the other one may have written.
And "if you assume ..."
We now use a more defensive variety of the assuming function, this fixes
a warning thrown by the valgrind tool.
sql/item_cmpfunc.cc:
c_ptr() makes incorrect assumptions about the string we get from
out of args[0]->val_str(&tmp); c_str_safe() is more defensive.
In some functions dealing with strings and character sets, the wrong

can lead to a wrong result.
All date/time functions has the STRING result type thus their results are
compared as strings. The string date representation allows a user to skip
some of leading zeros. This can lead to wrong comparison result if a date/time
function result is compared to such a string constant.
The idea behind this bug fix is to compare results of date/time functions
and data/time constants as ints, because that date/time representation is
more exact. To achieve this the agg_cmp_type() is changed to take in the
account that a date/time field or an date/time item should be compared
as ints.
This bug fix is partially back ported from 5.0.
The agg_cmp_type() function now accepts THD as one of parameters.
In addition, it now checks if a date/time field/function is present in the
list. If so, it tries to coerce all constants to INT to make date/time
comparison return correct result. The field for the constant coercion is
taken from the Item_field or constructed from the Item_func. In latter case
the constructed field will be freed after conversion of all constant items.
Otherwise the result is same as before - aggregated with help of the
item_cmp_type() function.
From the Item_func_between::fix_length_and_dec() function removed the part
which was converting date/time constants to int if possible. Now this is
done by the agg_cmp_type() function.
The new function result_as_longlong() is added to the Item class.
It indicates that the item is a date/time item and result of it can be
compared as int. Such items are date/time fields/functions.
Correct val_int() methods are implemented for classes Item_date_typecast,
Item_func_makedate, Item_time_typecast, Item_datetime_typecast. All these
classes are derived from Item_str_func and Item_str_func::val_int() converts
its string value to int without regard to the date/time type of these items.
Arg_comparator::set_compare_func() and Arg_comparator::set_cmp_func()
functions are changed to substitute result type of an item with the INT_RESULT
if the item is a date/time item and another item is a constant. This is done
to get a correct result of comparisons like date_time_function() = string_constant.
mysql-test/r/cast.result:

sql/item_timefunc.h:

Item_func_makedate.

The IN() function uses agg_cmp_type() to aggregate all types of its arguments
to find out some common type for comparisons. In this particular case the
char() and the int was aggregated to double because char() can contain values
like '1.5'. But all strings which do not start from a digit are converted to
0. thus 'a' and 'z' become equal.
This behaviour is reasonable when all function arguments are constants. But
when there is a field or an expression this can lead to false comparisons. In
this case it makes more sense to coerce constants to the type of the field
argument.
The agg_cmp_type() function now aggregates types of constant and non-constant
items separately. If some non-constant items will be found then their
aggregated type will be returned. Thus after the aggregation constants will be
coerced to the aggregated type.
mysql-test/t/func_in.test:

The convert_constant_item() function converts constant items to ints on
prepare phase to optimize execution speed. In this case it tries to evaluate
subselect which contains a derived table and is contained in a derived table.
All derived tables are filled only after all derived tables are prepared.
So evaluation of subselect with derived table at the prepare phase will
return a wrong result.
A new flag with_subselect is added to the Item class. It indicates that
expression which this item represents is a subselect or contains a subselect.
It is set to 0 by default. It is set to 1 in the Item_subselect constructor
for subselects.
For Item_func and Item_cond derived classes it is set after fixing any argument
in Item_func::fix_fields() and Item_cond::fix_fields accordingly.
The convert_constant_item() function now doesn't convert a constant item
if the with_subselect flag set in it.

If the second or the third argument of a BETWEEN predicate was
a constant expression, like '2005.09.01' - INTERVAL 6 MONTH,

The function agg_cmp_type in item_cmpfunc.cc neglected the fact that
the first argument in a BETWEEN/IN predicate could be a field of a view.
As a result in the case when the retrieved table was hidden by a view
over it and the arguments in the BETWEEN/IN predicates are of
the date/time type the function did not perform conversion of
the constant arguments to the same format as the first field argument.
If formats of the arguments differed it caused wrong a evaluation of
the predicates.
