Select 我如何修复错误；选择既不分组也不聚合的列表表达式[…]引用"；在BigQuery中？,select,group-by,google-bigquery,reference,aggregate,Select,Group By,Google Bigquery,Reference,Aggregate,在BigQuery中运行以下查询时，我收到错误“select list expression Opportunity.id references is not grouped and aggregated”： SELECT Opportunity.id AS `Opportunity_Id`, Opportunity.testing_only__c AS `Opportunity_Testing_only`, MAX(DatedConversionRate.startdate) AS

在BigQuery中运行以下查询时，我收到错误“select list expression Opportunity.id references is not grouped and aggregated”：

SELECT
  Opportunity.id AS `Opportunity_Id`,
  Opportunity.testing_only__c AS `Opportunity_Testing_only`,
  MAX(DatedConversionRate.startdate) AS `DatedConversionRate_Start_date`,
FROM
  `dataset.Opportunity` Opportunity
LEFT JOIN 
  `dataset.DatedConversionRate` DatedConversionRate 
  ON DatedConversionRate.isocode = Opportunity.currencyisocode
WHERE
  DatedConversionRate.startdate < CURRENT_TIMESTAMP()

选择
Opportunity.id为'Opportunity\u id`，
Opportunity.testing_only__c作为'Opportunity_testing_only'，
最大值（DatedConversionRate.startdate）为“DatedConversionRate\u Start\u date”，
从…起
`数据集.机遇`机遇
左连接
`dataset.DatedConversionRate`DatedConversionRate
日期转换率.isocode=Opportunity.CurrencySocode
哪里
DatedConversionRate.startdate<当前时间戳（）

问题是什么？我如何解决它？

从

中删除Opportunity.id
选择或按其分组：
SELECT
  Opportunity.id AS `Opportunity_Id`,
  MAX(DatedConversionRate.startdate) AS `DatedConversionRate_Start_date`,
FROM
  `dataset.Opportunity` Opportunity
LEFT JOIN 
  `dataset.DatedConversionRate` DatedConversionRate 
  ON DatedConversionRate.isocode = Opportunity.currencyisocode
WHERE
  DatedConversionRate.startdate < CURRENT_TIMESTAMP()
GROUP BY Opportunity.id

选择
Opportunity.id为'Opportunity\u id`，
最大值（DatedConversionRate.startdate）为“DatedConversionRate\u Start\u date”，
从…起
`数据集.机遇`机遇
左连接
`dataset.DatedConversionRate`DatedConversionRate
日期转换率.isocode=Opportunity.CurrencySocode
哪里
DatedConversionRate.startdate<当前时间戳（）
按Opportunity.id分组
如果我添加了groupby Opportunity.id，那么在下一个选择中，错误将被类似的错误所取代：“选择list expression Opportunity.testing_only__c引用，它既不是分组的，也不是聚合的”也将其分组：groupby Opportunity.id，Opportunity.testing_only___c
，因此如果我选择了30个字段，我必须按所有人分组？如果你有max（）
-那么是的。
