Azure Stream Analytics 同时结合数据

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 {"46027020", "#A83","2017-05-18T08:47:26.5620000Z"} header "IGEF_NR"、"Decklack" 和 "time" 第二行：{"46027070", "#475","2017-05-18T08:49:20.1750000Z"}

Answer 1

您需要将过滤器子查询拆分为 "IGEF_NR" 和 "DECKLACK"，然后加入两者。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
