In fact this substitution can be allowed if the field is
not of a type string or if the field reference serves as
an argument of a comparison predicate.
mysql-test/r/func_str.result:

sql/item.cc:
Fixed bug #21198.
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
the latter returns TRUE it proceeds with a transformation performed by
another callback function.
sql/item_cmpfunc.h:
Fixed bug #21698.
Added the implementations of 'subst_argument_checker'
for the Item_func and Item_cond classes.
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.
Added the declaration of an implementation of the compile method for
class Item_cond.
First it processes the Item_cond node with a callback function and if
the latter returns TRUE it proceeds with a transformation performed by
another callback function.

Limited the conditions at which a field can be substituted
a for an equal constant in a formula.
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.
Select_type in the EXPLAIN output for the query SELECT * FROM t1 was
'SIMPLE', while for the query SELECT * FROM v1, where the view v1
was defined as SELECT * FROM t1, the EXPLAIN output contained 'PRIMARY'

1003: Incorrect table name
in multi-table DELETE the set of tables to delete from actually
references then tables in the other list, e.g:
DELETE alias_of_t1 FROM t1 alias_of_t1 WHERE ....
is a valid statement.
So we must turn off table name syntactical validity check for alias_of_t1
because it's not a table name (even if it looks like one).
In order to do that we add a special flag (TL_OPTION_ALIAS) to
disable the name checking for the aliases in multi-table DELETE.

Made the parser to support parenthesis around UNION branches.
This is done by amending the rules of the parser so it generates the correct
structure.
Currently it supports arbitrary subquery/join/parenthesis operations in the
EXISTS clause.
In the IN/scalar subquery case it will allow adding nested parenthesis only
if there is an UNION clause after the parenthesis. Otherwise it will just
treat the multiple nested parenthesis as a scalar expression.
It adds extra lex level for ((SELECT ...) UNION ...) to accommodate for the
UNION clause.

Sorting by RAND() uses a temporary table in order to get a correct results.
User defined variable was set during filling the temporary table and later
on it is substituted for its value from the temporary table. Due to this
it contains the last value stored in the temporary table.
Now if the result_field is set for the Item_func_set_user_var object it
updates variable from the result_field value when being sent to a client.
The Item_func_set_user_var::check() now accepts a use_result_field
parameter. Depending on its value the result_field or the args[0] is used
to get current value.
