`articles.gmt_delete+tags.type` is an select expression, both the original column name and table name should be empty. 42 is a literal, both the original column name and table name should be empty too. `id` is ambiguous here. Proper SQL might require it be prefixed with qualifier (either `articles` or `tags`). Then both table name and table alias name are known.
