问题 Could anyone explain {elapsed_time} & {memory_usage} pseudo-variables in CodeIgniter? What template is this referring to?

问题 I have this query and I need it to be in the CodeIgniter way (query builder). I know how to use the standard query builder class functions, but I have difficulties to find a way how to build a LEFT JOIN with an inner SELECT clause using the CI Query Builder Class. SELECT * FROM sma_products p LEFT JOIN (SELECT product_id, Count(*) FROM sma_sale_items GROUP BY product_id) s ON p.id = s.product_id ORDER BY ` Count(*) ` DESC 回答1: The difficulty to create this SQL with CI query builder lies in
