SHOW FULL COLUMNS FROM `jrk_downrecords` [ RunTime:0.001063s ]
SELECT `a`.`aid`,`a`.`title`,`a`.`create_time`,`m`.`username` FROM `jrk_downrecords` `a` INNER JOIN `jrk_member` `m` ON `a`.`uid`=`m`.`id` WHERE `a`.`status` = 1 GROUP BY `a`.`aid` ORDER BY `a`.`create_time` DESC LIMIT 10 [ RunTime:0.063535s ]

UPDATE `jrk_articles` SET `hits` = 2 WHERE `id` = 216071 [ RunTime:0.014855s ]
