Question

我想知道如何避免执行期间超出的资源＆＃34;错误。关于此问题的大多数其他问题涉及每次加入或每次组合，但我已经没有使用过这些问题了。如果我在日期或ABS（HASH（userId））上包含WHERE子句，那么查询可以工作，但我希望整个数据集可用，然后我会进一步过滤它在Tableau中。

如果删除t4查询有效，但我想要最后一列，并且我希望在event_parameters字段中创建更多列以供稍后查询使用。

Answer 1

超出资源的一般建议可以在这里找到： https://stackoverflow.com/a/16579558/1375400

请注意，添加EACH通常是资源超出错误的解决方案，而不是原因。（虽然有些情况下它可以反过来工作！）

此外，EACH对GROUP BY不再有意义，并且很快就会在JOIN上无关紧要。

我认为你应该只用一个简单的扫描＆＃34;来做你所有的逻辑根本没有加入！
像下面的东西。只是想法 - 但有机会按原样运作：）

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
