In other words: what you probably meant here is
FROM (c_custom_fields AS fieldx CROSS JOIN j_product_groups_fields AS join_table)
LEFT JOIN c_custom_fields_options AS optionx ON optionx.field_id = fieldx.field_id
(The parentheses aren't required in this particular case but they help
clarify your intent.)
We are aware that there are certain standards-challenged products
that get this wrong.
