When optimizing conditions like 'a = <some_val> OR a IS NULL' so that they're
united into a single condition on the key and checked together the server must
check which value is the NULL value in a correct way : not only using ->is_null
but also check if the expression doesn't depend on any tables referenced in the
current statement.
This additional check must be performed because that optimization takes place
before the actual execution of the statement, so if the field was initialized
to NULL from a previous statement the optimization would be applied incorrectly.

demonstrating the problem fixed by this changeset.

The problem was in that opt_sum_query() replaced MIN/MAX functions
with the corresponding constant found in a key, but due to imprecise
representation of float numbers, when evaluating the where clause,
this comparison failed.
When MIN/MAX optimization detects that all tables can be removed,
also remove all conjuncts in a where clause that refer to these
tables. As a result of this fix, these conditions are not evaluated
twice, and in the case of float number comparisons we do not discard
result rows due to imprecise float representation.
As a side-effect this fix also corrects an unnoticed problem in
bug 12882.
mysql-test/r/func_group.result:
BUG#20954 - test result adjustment.
Adjusted the test result of bug 12882 which was not preperly fixed.
The current patch corrects the problem that was fully corrected by the
patch for 12882.
The problem was that opt_sum_query() indicated that the optimizer may
remove all tables because all MIN/MAX/COUNT functions are constants,
but this lead to an empty result instead of NULL because the WHERE
clause was still evaluated.
The current fix removes all conjuncts in the where clause that
reference the removed tables, and thus corrects the problem.

The Field::eq() considered instances of Field_bit that differ only in
bit_ptr/bit_ofs equal. This caused equality conditions optimization
(build_equal_items_for_cond()) to make bad field substitutions that result
in wrong predicates.

in addition to Field::eq().

a worse execution plan than in 4.1 for some queries.
It happened due the fact that at some conditions the
optimizer always preferred range or full index scan access
methods to lookup access methods even when the latter were much
cheaper.
The problem was not observed in 4.1 for the reported query
because the WHERE condition was not of a form that could
cause the problem.
Equality propagation introduced on 5.0 added an extra
predicate and changed the WHERE condition. The new condition
provoked the optimizer to make a bad choice.
The problem was fixed by the patch for bug 17379.

functions are involved.
When subselect is a join with set functions and no record have been found in
it, end_send_group() sets null_row for all tables in order aggregate functions
to calculate their values correctly. Normally this null_row flag is cleared for
each table in sub_select(), but flush_cached_records() doesn't do so.
Due to this all fields from the table processed by flush_cached_records() are
always evaluated as nulls and whole select produces wrong result.

Item equal objects are employed only at the optimize phase. Usually they are not
supposed to be evaluated. Yet in some cases we call the method val_int() for
them. Here we have to take care of restricting the predicate such an object
represents f1=f2= ...=fn to the projection of known fields fi1=...=fik.
Added a check for field's table being const in Item_equal::val_int().
If the field's table is not const val_int() just skips that field when

The cause for the bug is that the priorities of all rules/terminals
that process the FROM clause are not fully specified, and the
parser generator produces a parser that doesn't always parse
the FROM clause so that JOINs are left-associative. As a result
the final join tree produced by the parser is incorrect, which
is the cause for subsequent name resolution to fail.

if ESCAPE was in the statement check whether its length is

sql/item_cmpfunc.h:

ESCAPE clause was found in the statement

pass FALSE for escape_used_in_parsing because we

sql/sql_lex.h:

sql/sql_yacc.yy:
initialize Lex->escape_used and then use it when reducing.
This is needed as fix for bug #12595 to distinguish between
situation where ESCAPE was found and when not because internally
we may pass a string an empty string and there is no other way
to find out whether this is correct or not in case of
NO_BACKSLASH_ESCAPES mode, which allows only length of 1 if
ESCAPE is part of the SQL statement.

Test BLOB and VARCHAR sorting
sql/field.cc:
Store length last in VARBINARY() and BLOB() columns to get shorter strings sorted before longer onces
sql/field.h:
Added method 'sort_length()' to allow one to have length bytes last for VARBINARY/BLOB to get these to sort properly
sql/filesort.cc:
Use 'sort_length()' instead of 'pack_length()' to get length of field.
Store suffix_length last for varbinary (blob) objects.
The above ensures that BLOB/VARBINARY are correctly sorted (shorter strings before longer ones)
sql/sql_class.h:
Added sort suffix length (to get varbinary/blob to sort correctly)
sql/sql_select.cc:
Use sort_length() instead of pack_lengths()
strings/ctype-bin.c:
Don't let strnxfrm_bin store length last
Better to do it in MySQL field object to ensure it's done properly for all cases
