Question

我尝试在sql控制台中执行此BigQuery语句但是我收到如下错误。

有人可以就此提出建议吗？

"Error: Encountered " "OVER" "OVER "" at line 5, column 99. Was expecting: "END" ..."

SELECT      *
FROM        (SELECT
                  *
                        , CASE 
                            WHEN initiator in ('01_User') THEN RANK() OVER (PARTITION BY item_id, log_date_desc, type ORDER BY log_date_desc DESC)
              ELSE RANK() OVER (PARTITION BY item_id, log_date_desc ORDER BY log_date_desc  DESC) 
              END AS ord
            FROM        temp.step1_itemlogall
            ) AS t
WHERE       ord = 1

感谢。

我认为问题在于将分析函数放在CASE语句中。您可以将其重写为计算这两个函数的内部选择，然后在外部查询中选择正确的函数。例如：

SELECT *
FROM (
  SELECT    
    CASE WHEN initiator IN ('01_User') 
    THEN ord1
    ELSE ord2    
    END AS ord
  FROM (  
  SELECT *,
      RANK() OVER (PARTITION BY item_id, log_date_desc, type
                   ORDER BY log_date_desc DESC) as ord1,
      RANK() OVER (PARTITION BY item_id, log_date_desc 
                   ORDER BY log_date_desc  DESC) as ord2
    FROM temp.step1_itemlogall))
WHERE ord = 1

在用户界面或API调用中切换到标准SQL，只有旧版SQL引擎会引发此错误。
