我有一张有以下信息的table。

Table: DETAILS
id     received     site
(PK)   timestamp    varchar

每天有几千个条目，站点信息是硬编码的（.com、def.com等）。我想得到上周每天点击量的摘要，这样的结果是：

site     count(11/04)   count(10/04)    count(09/04) count(08/04)     
abc.com  300            320             310          320
def.com  200            210             200          220
ghi.com  300            320             310          320
jkl.com  200            210             200          220

或：

received  abc.com       def.com          ghi.com     jkl.com
11/04     300           320              310         320
10/04     200           210              200         220
09/04     300           320              310         320
08/04     200           210              200         220
07/04     300           320              310         320

谢谢大家。

您可以使用一个准备好的语句生成查询，例如上周的语句：

-- Generate Query for last week (from Monday to Sunday)
-- store query in @myQuery
--
SELECT CONCAT(
'SELECT site,\n',
'sum(if(date(received) = \'', DATE(NOW() - INTERVAL (DAYOFWEEK(NOW())-1) day),'\',1,0)) as `count(',DATE_FORMAT(NOW() - INTERVAL (DAYOFWEEK(NOW())-1) day,'%d/%m'),')`,\n'
'sum(if(date(received) = \'', DATE(NOW() - INTERVAL (DAYOFWEEK(NOW())+0) day),'\',1,0)) as `count(',DATE_FORMAT(NOW() - INTERVAL (DAYOFWEEK(NOW())+0) day,'%d/%m'),')`,\n'
'sum(if(date(received) = \'', DATE(NOW() - INTERVAL (DAYOFWEEK(NOW())+1) day),'\',1,0)) as `count(',DATE_FORMAT(NOW() - INTERVAL (DAYOFWEEK(NOW())+1) day,'%d/%m'),')`,\n'
'sum(if(date(received) = \'', DATE(NOW() - INTERVAL (DAYOFWEEK(NOW())+2) day),'\',1,0)) as `count(',DATE_FORMAT(NOW() - INTERVAL (DAYOFWEEK(NOW())+2) day,'%d/%m'),')`,\n'
'sum(if(date(received) = \'', DATE(NOW() - INTERVAL (DAYOFWEEK(NOW())+3) day),'\',1,0)) as `count(',DATE_FORMAT(NOW() - INTERVAL (DAYOFWEEK(NOW())+3) day,'%d/%m'),')`,\n'
'sum(if(date(received) = \'', DATE(NOW() - INTERVAL (DAYOFWEEK(NOW())+4) day),'\',1,0)) as `count(',DATE_FORMAT(NOW() - INTERVAL (DAYOFWEEK(NOW())+4) day,'%d/%m'),')`,\n'
'sum(if(date(received) = \'', DATE(NOW() - INTERVAL (DAYOFWEEK(NOW())+5) day),'\',1,0)) as `count(',DATE_FORMAT(NOW() - INTERVAL (DAYOFWEEK(NOW())+5) day,'%d/%m'),')`\n',
'FROM yourTable\n',
'WHERE received BETWEEN \'',DATE_FORMAT(NOW() - INTERVAL (DAYOFWEEK(NOW())+5) day,'%Y-%m-%d 00:00:00'),'\' AND \'',DATE_FORMAT(NOW() - INTERVAL (DAYOFWEEK(NOW())-1) day,'%Y-%m-%d 23:59:59'),'\'\n',
'GROUP by site\n',
'ORDER by site;'
) INTO @myQuery;

-- Prepare and execute Query
--
PREPARE stmt FROM @myQuery;
EXECUTE stmt;

-- Free Prepare
--
DEALLOCATE PREPARE stmt;

结果
