1、資料庫中desc是descend 降序意思、asc是ascend 升序意思

/* 按照新時間排序 */ SELECT * FROM download_qx/*表名*/ ORDER BY createTime/*表時間欄位*/ DESC 

/* 按照老時間排序 */ SELECT * FROM download_qx/*表名*/ ORDER BY createTime/*表時間欄位*/ ASC 

/* qx,name模糊查詢 */ SELECT * FROM upload_file WHERE CONCAT(qx,NAME) LIKE '%2%' GROUP BY qx,NAME; 

/* qx模糊查詢 單條 */ SELECT * FROM upload_file WHERE qx LIKE '%2%' GROUP BY qx; 

 /* qx模糊查詢 全部 */ SELECT * FROM upload_file WHERE qx LIKE '%2%';
