Putting the product class into a library file doesn't really work, either. To

问题 SELECT * FROM certs WHERE id NOT IN (SELECT id_cer FROM revokace); How do I write the above select statement in CodeIgniter active record? 回答1: ->where() support passing any string to it and it will use it in the query.
