Sql BigQuery：如何避免“查询执行期间超出资源”。错误

我想知道如何避免在执行错误期间超出资源。关于这一点的大多数其他问题都涉及到加入每个人或每个人分组，但我已经没有使用这些问题了。如果我在日期或ABSHASHuserId上包含WHERE子句，那么查询可以工作，但我希望整个数据集都可用，然后我将在Tableau中进一步过滤它

如果我删除t4，查询将正常工作，但我需要最后一列，并且我将需要从event_parameters字段中创建更多的列，以供以后的查询使用

我认为你应该能够在一次简单的扫描中完成你所有的逻辑。 根本没有加入！ 像下面这样。只是一个想法-但有一些机会按原样工作：

SELECT
    userId,
    event_time,
    MAX(CASE WHEN event_parameters.Name = 'Diamond_Balance' 
            THEN INTEGER(event_parameters.Value) END) AS Diamond_Balance,
    MAX(CASE WHEN event_parameters.Name = 'Diamond_Change' AND INTEGER(event_parameters.Value ) BETWEEN -14000 AND 14000 
            THEN INTEGER(event_parameters.Value)) END AS Diamond_Change,
    MAX(CASE WHEN event_parameters.Name = 'Gold_Balance' 
            THEN INTEGER(event_parameters.Value) END) AS Gold_Balance,
    MAX(CASE WHEN event_parameters.Name = 'Gold_Change' 
            THEN INTEGER(event_parameters.Value) END) AS Gold_Change
FROM
    FLATTEN([game_data], event_parameters)
WHERE
    event_name LIKE 'Currency'
GROUP BY
    userId,
    event_time

有关超出资源的一般建议，请参见：

请注意，添加每个都通常是资源超出错误的解决方案，而不是原因。虽然在某些情况下，它可以反过来工作

此外，每个问题在分组时都不再有意义，在加入时很快就会变得无关紧要。

谢谢，我已经读过这个问题，但我肯定没有注意到每个问题都是问题的解决方案。添加JOIN-EACH使查询工作起来。感谢Mikhail，这也起了作用，是一个更简单的解决方案。我不确定它对于字符串而不是整数的事件参数将如何工作。只需删除整数即可
