见：《MySQL实战基础知识入门(10)：今天、昨天、近7天、近30天在一个筛选语句内实现的解决方案》上文是时间段的数据合计统计；见《MySQL实战基础知识入门(3)：近7日销量合计php后端mysql语句如果当日为空则自动补0的解决方案》上文是最近七日每日的分别统计。如果只是为了7天，写那么字段也就算了。但是遇见了统计30天内每天的数据时，是不是哭了呢？新的MYSQL筛选语句： $sql = "select DATE_FORMAT(a.paid_at,'%Y-%m-%d') .
public function getData() { global $db, $res; dbc(); //分组序列号; $jk_sn = "6910001582"; //当日分区数据; $partName = get_param("partName"); if (empty($partName)) { //$partName = "jk_data" . date("Ymd"); $partName = "jk_data20201113"; } $sql.

//刷队列，取数据 while (true) { $msg = code(trim(rand(2, 60))); var_dump(trim($msg)); sleep(5); socket_write($msgsock, $msg, strlen($msg)); }Done!
mysql直接通过phpmyadmin导入csv文件excle编辑好文件，需要日期和时间类型，必须是两位数；保存csv后，需要用记事本打开，再次另存为"utf-8"编码，默认保存的是ANSI编码；phpmyadmin选择“CSV using LOAD DATA”格式；字段分隔符和CSV文件一致；Done！...
