Question

我正在使用azure流分析查询语言，我在数据准备方面遇到了一些问题。this is my current output

但我想同时合并数据例如在第一行 {＆＃34; 46027020＆＃34;，＆＃34;＃A83＆＃34;，＆＃34; 2017-05-18T08：47：26.5620000Z＆＃34;} 标题＆＃34; IGEF_NR＆＃34;，＆＃34; Decklack＆＃34;和＆＃34;时间＆＃34; 第二行：{＆＃34; 46027070＆＃34;，＆＃34;＃475＆＃34;，＆＃34; 2017-05-18T08：49：20.1750000Z＆＃34;}

Answer 1

您需要将过滤器子查询拆分为＆＃34; IGEF_NR＆＃34;和＆＃34; DECKLACK＆＃34;，然后加入两个。如下所示：

filter_IGEF AS
(
  SELECT sub_id, value,time
  FROM stringfilter
  WHERE sub_id = 'IGEF_Nr'
 ),

 filter_Decklack AS
(
  SELECT sub_id, value,time
  FROM stringfilter
  WHERE sub_id = 'Decklack'
 ),

 joined_value AS
 (
   SELECT
     i.value AS IGEF_Nr,
     d.value AS Decklack,
     i.time as time
   FROM filter_IGEF i
   JOIN filter_Decklack d
   ON i.time = d.time
   AND DATEDIFF(second, i, d) BETWEEN 0 AND 5
 )

 SELECT IGEF_Nr, Decklack, time
 INTO csv
 FROM joined_value

azure流分析将数据同时组合在一起
