google visual data studio 中的 bigquery 错误声明变量

Question

我在 google BigQuery 上查询相同的代码，它运行在 google bigquery 上很好，然后我复制到 visual data studio，它有错误 "Data set configuration error"，我不明白这个错误 enter image description here ，请帮助我。我认为问题的原因是在 BigQuery 中声明变量

DECLARE yesterday date;
DECLARE count_week01 INT64;--number user active in (last week -1)
DECLARE count_week0 INT64;--number user active in (last week)
DECLARE retention FLOAT64; -- % user has already actived
DECLARE churn_rate FLOAT64; -- % user has already leaved
DECLARE count_user_active_week0 INT64; -- % user has leave
DECLARE week0_begin string; --date begin of last week
DECLARE week0_end string; --date end of last week

DECLARE week01_begin string; --date begin of (last week - 1)
DECLARE week01_end string; --date end of (last week -1)

SET yesterday =  DATE_ADD(CURRENT_DATE(), INTERVAL -1 DAY);

--Set value for last week from yesterday
SET week0_begin =  FORMAT_DATE('%Y%m%d', DATE_ADD(yesterday, INTERVAL -6 DAY));
SET week0_end = FORMAT_DATE('%Y%m%d', yesterday);
--Set value for (last week -1) from yesterday
SET week01_begin =  FORMAT_DATE('%Y%m%d', DATE_ADD(yesterday, INTERVAL -13 DAY));
SET week01_end =   FORMAT_DATE('%Y%m%d', DATE_ADD(yesterday, INTERVAL -7 DAY));

--Count number user active time in last week -1
SET count_week01 = (SELECT COUNT(DISTINCT param.value.string_value) as phone
FROM  `analytics_223664948.events_*` ev,
UNNEST(event_params) AS param
WHERE ev.event_name = 'spl_active_time' and param.key = 'PhoneNumber' AND _TABLE_SUFFIX BETWEEN week01_begin AND week01_end);

--Count number user active time in last week
SET count_week0 = (SELECT COUNT(DISTINCT param.value.string_value) as phone
FROM  `analytics_223664948.events_*` ev,
UNNEST(event_params) AS param
WHERE ev.event_name = 'spl_active_time' and param.key = 'PhoneNumber' AND _TABLE_SUFFIX BETWEEN week0_begin AND week0_end);

--Join last week and last week -1
SET count_user_active_week0 = (SELECT COUNT(week0.phone) FROM
(
  (SELECT DISTINCT param.value.string_value as phone
  FROM  `analytics_223664948.events_*` ev,
  UNNEST(event_params) AS param
  WHERE ev.event_name = 'spl_active_time' and param.key = 'PhoneNumber' AND _TABLE_SUFFIX BETWEEN week0_begin AND week0_end) week0
  INNER JOIN 
  (SELECT DISTINCT param.value.string_value as phone
  FROM  `analytics_223664948.events_*` ev,
  UNNEST(event_params) AS param
  WHERE ev.event_name = 'spl_active_time' and param.key = 'PhoneNumber' AND _TABLE_SUFFIX BETWEEN week01_begin AND week01_end) week01
  ON week0.phone = week01.phone 
)
);
SET retention = 100*count_user_active_week0/count_week01;
SET churn_rate = 100 - retention;

SELECT week01_begin, week01_end, week0_begin, week0_end, count_week0, count_week01, retention, churn_rate
