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.

/*
|
||||
Generic iterator over the fields of an arbitrary table reference.
|
||||
|
||||
DESCRIPTION
|
||||
This class unifies the various ways of iterating over the columns
|
||||
of a table reference depending on the type of SQL entity it
|
||||
represents. If such an entity represents a nested table reference,
|
||||
this iterator encapsulates the iteration over the columns of the
|
||||
members of the table reference.
|
||||
|
||||
IMPLEMENTATION
|
||||
The implementation assumes that all underlying NATURAL/USING table
|
||||
references already contain their result columns and are linked into
|
||||
the list TABLE_LIST::next_name_resolution_table.
