从 Google Data Studio 调用 Bigquery 存储过程

Question

知道如何从 Google 数据工作室调用 bigquery 存储过程吗？我有一个使用 Bigquery 过程完成的递归查询要求。但是需要从 datastudio 报告中将参数传递给这个过程，并获得相同的结果并显示在 Data studio 报告中。我曾尝试从 Data Studio 中的自定义查询调用该过程，但没有成功。 Datastudio 抛出错误。我尝试从函数调用过程，但它不起作用。任何想法？如何从 Google Data Studio 调用程序？

编写的程序

DECLARE stop INT64 DEFAULT 30;
    DECLARE v_target string;
    DECLARE v_target_column_name string;
    DECLARE max_counter INT64;
    DECLARE min_counter INT64;
    DECLARE v_exists bool;
    SET v_target = 'v_target';
    SET v_target_column_name = 'v_target_col';
    create or replace table test.poc_sttm_resp as
    select ROW_NUMBER() OVER() as counter,'N' as flag,source,source_column_name,target,target_column_name from test.test_sttm where target = v_target and target_column_name = v_target_column_name;
    LOOP
    SET max_counter = (select max(counter) from test.poc_sttm_resp);
    SET min_counter = (select min(counter) from test.poc_sttm_resp where flag = 'N');
    SET v_exists = EXISTS(select s.source from test.test_sttm s inner join
      (select source,source_column_name from test.poc_sttm_resp where counter =  min_counter
      ) r
      on s.target = r.source and
      s.target_column_name = r.source_column_name);
      IF stop = 0  OR min_counter is null THEN
        LEAVE;
      END IF;
      IF v_exists then
      insert into test.poc_sttm_resp
      select ROW_NUMBER() OVER() + max_counter as counter,'N' as flag,s.source,s.source_column_name,target,target_column_name from test.test_sttm s inner join
      (select source,source_column_name from test.poc_sttm_resp where counter = (select min(counter) from test.poc_sttm_resp where flag = 'N')) r
      on s.target = r.source and
      s.target_column_name = r.source_column_name;
      END IF;
      update test.poc_sttm_resp set flag = 'Y' where counter = min_counter;
        SET stop = stop - 1;
    END LOOP;

我尝试从 Data Studio 调用该过程， call functions.testproc(); 没用

Answer 1

您是否尝试使用社区连接器在 Google Data Studio 和 BigQuery 之间建立连接？
使用社区连接器，您可以触发带有参数的存储过程。

Answer 2

仔细检查您已连接correctly

你需要create/add the parameter在data source或Data Studio里面通过add parameter

在数据源中

1. Sign in to Data Studio.
2. Edit your data source.
3. In the upper right, click ADD A PARAMETER.
4. You can also create a parameter while editing a report by selecting a component, then in the bottom right, clicking ADD A PARAMETER. Be sure to select a component based on the desired data source.
5. Configure the parameter's options and default value (see below).

此外，在页面上向下滚动，您将看到一个示例，说明如何通过示例计算执行此操作。
