SYNOPSIS
Field_iterator_table_ref::get_or_create_column_ref()
is_created [out] set to TRUE if the column was created,
FALSE if we return an already created colum
parent_table_ref the parent table reference over which the
iterator is iterating
DESCRIPTION
TODO
Create a new natural join column for the current field of the
iterator if no such column was created, or return an already
created natural join column. The former happens for base tables or
views, and the latter for natural/using joins. If a new field is
created, then the field is added to 'parent_table_ref' if it is
given, or to the original table referene of the field if
parent_table_ref == NULL.
NOTES
This method is designed so that when a Field_iterator_table_ref
walks through the fields of a table reference, all its fields
are created and stored as follows:
- If the table reference being iterated is a stored table, view or
natural/using join, store all natural join columns in a list
attached to that table reference.
- If the table reference being iterated is a nested join that is
not natural/using join, then do not materialize its result
fields. This is OK because for such table references
Field_iterator_table_ref iterates over the fields of the nested
table references (recursively). In this way we avoid the storage
of unnecessay copies of result columns of nested joins.
RETURN
# Pointer to a column of a natural join (or its operand)
