DATE/DATETIME values are out of the currently supported
 4 basic value types (INT,STRING,REAL and DECIMAL).
 So expressions (not fields) of compile type DATE/DATETIME are 
 generally considered as STRING values. This is not so
 when they are compared : then they are compared as 
 INTEGER values.
 But the rule for comparison as INTEGERS must be checked
 explicitly each time when a comparison is to be performed.
 filesort is one such place. However there the check was 
 not done and hence the expressions (not fields) of type 
 DATE/DATETIME were sorted by their string representation.
 Fixed to compare them as INTEGER values for filesort.

Functions over sum functions wasn't set up correctly for the ORDER BY clause
which leads to a wrong order of the result set.

The split_sum_func() function is called now for each ORDER BY item that
contains a sum function to set it up correctly.

When the ORDER BY clause gets fixed it's allowed to search in the current
item_list in order to find aliased fields and expressions. This is ok for a
SELECT but wrong for an UPDATE statement. If the ORDER BY clause will
contain a non-existing field which is mentioned in the UPDATE set list
then the server will crash due to using of non-existing (0x0) field.

When an Item_field is getting fixed it's allowed to search item list for
aliased expressions and fields only for selects.

Several problems here :
 1. The conversion to double of an hex string const item
 was not taking into account the unsigned flag.
 
 2. IN was not behaving in the same was way as comparisons
 when performed over an INT/DATE/DATETIME/TIMESTAMP column
 and a constant. The ordinary comparisons in that case 
 convert the constant to an INTEGER value and do int 
 comparisons. Fixed the IN to do the same.
 
 3. IN is not taking into account the unsigned flag when 
 calculating <expr> IN (<int_const1>, <int_const2>, ...).
 Extended the implementation of IN to store and process
 the unsigned flag for its arguments.

This is not the case as it can return NULL
for invalid hexidecimal strings.
Fixed by setting the maybe_null flag.

When INSERT is done over a view the table being inserted into is 
checked to be unique among all views tables. But if the view contains
self-joined table an error will be thrown even if all tables are used under
different aliases.

The unique_table() function now also checks tables' aliases when needed.

it doesn't select.

This bug was fixed along with bug #16861: User defined variable can 
have a wrong value if a tmp table was used.

There the fix consisted of Item_func_set_user_var overloading the method
Item::save_in_field. Consider the query from the test case:


INSERT INTO foo( bar, baz )
SELECT 
  bar,
  @newBaz := 1 + baz
FROM 
  foo
WHERE 
  quux <= 0.1;

Here the assignment expression '@newBaz := 1 + baz' is represented by an 
Item_func_set_user_var. Its member method save_in_field, which writes the 
value of this assignment into the result field, writes the val_xxx() value, 
which is not updated at this point. In the fix introduced by the patch,
the save_in_field method reads the actual variable value instead.

created for sorting.

Any outer reference in a subquery was represented by an Item_field object.
If the outer select employs a temporary table all such fields should be
replaced with fields from that temporary table in order to point to the 
actual data. This replacement wasn't done and that resulted in a wrong
subquery evaluation and a wrong result of the whole query.

Now any outer field is represented by two objects - Item_field placed in the
outer select and Item_outer_ref in the subquery. Item_field object is
processed as a normal field and the reference to it is saved in the
ref_pointer_array. Thus the Item_outer_ref is always references the correct
field. The original field is substituted for a reference in the
Item_field::fix_outer_field() function.

New function called fix_inner_refs() is added to fix fields referenced from
inner selects and to fix references (Item_ref objects) to these fields.

The new Item_outer_ref class is a descendant of the Item_direct_ref class.
It additionally stores a reference to the original field and designed to
behave more like a field.
