SYNOPSIS
add_join_natural()
a Table to do normal join with
b Do normal join with this table
a Left join argument
b Right join argument
using_fields Field names from USING clause
IMPLEMENTATION
This function just marks that table b should be joined with a.
The function setup_cond() will create in b->on_expr a list
of equal condition between all fields of the same name.
This function marks that table b should be joined with a either via
a NATURAL JOIN or via JOIN ... USING. Both join types are special
cases of each other, so we treat them together. The function
setup_conds() creates a list of equal condition between all fields
of the same name for NATURAL JOIN or the fields in 'using_fields'
for JOIN ... USING. The list of equality conditions is stored
either in b->on_expr, or in JOIN::conds, depending on whether there
was an outer join.
EXAMPLE
SELECT * FROM t1 NATURAL LEFT JOIN t2
<=>
SELECT * FROM t1 LEFT JOIN t2 ON (t1.i=t2.i and t1.j=t2.j ... )
SELECT * FROM t1 NATURAL JOIN t2 WHERE <some_cond>

SELECT * FROM t1, t2 WHERE (t1.i=t2.i and t1.j=t2.j and <some_cond>)
