我有一张包含以下信息的表格。
Cross Reference Table每天有几千个条目，网站信息是硬编码的（abc.com，def.com等）。我想得到上周每天点击的摘要，结果将是：
Table: DETAILS
id received site
(PK) timestamp varchar
或：
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
谢谢大家。

您可以使用上周准备好的状态生成查询：
-- 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'

'GROUP by site\n',
'ORDER by site;'
