Question

运行以下查询时出现资源超出错误，如何重写此查询以避免该错误？

SELECT
  XXX_lnaourj_ID,
  XXX_DR_Tma_LC,
  XXX_CR_Tma_LC,
  XXX_Amount_LC,
  XXX_TLAffect_LC,
  XXX_Entry_Desc,
  XXX_DocType,
  XXX_TCode,
  XXX_Company,
  XXX_Posted_By,
  XXX_Parked_By,
  XXX_Accounting_Date,
  XXX_Creation_Date
FROM
  [acl_data.XXX_JE_All_Formatted]
WHERE
  XXX_lnaourj_ID IN (
  SELECT
    XXX_lnaourj_ID
  FROM
    [acl_data.XXX_JE_All_Formatted]
  WHERE
    XXX_Creation_Date - XXX_Accounting_Date > 30 )
ORDER BY
  XXX_lnaourj_ID ASC;

Answer 1

由于您在主semijin中使用相同的表，因此可以简化查询以避免这种自我半连接（并避免两次执行表扫描）。取决于结果的大小，删除ORDER BY也可能有所帮助：

SELECT
  XXX_lnaourj_ID,
  XXX_DR_Tma_LC,
  XXX_CR_Tma_LC,
  XXX_Amount_LC,
  XXX_TLAffect_LC,
  XXX_Entry_Desc,
  XXX_DocType,
  XXX_TCode,
  XXX_Company,
  XXX_Posted_By,
  XXX_Parked_By,
  XXX_Accounting_Date,
  XXX_Creation_Date
FROM
  [acl_data.XXX_JE_All_Formatted]
WHERE
  XXX_Creation_Date - XXX_Accounting_Date > 30

Answer 2

尝试通过添加＆＃34; group by＆＃34;来欺骗Bigquery。在子查询中。它有时对我有帮助。

SELECT
  XXX_lnaourj_ID,
  XXX_DR_Tma_LC,
  XXX_CR_Tma_LC,
  XXX_Amount_LC,
  XXX_TLAffect_LC,
  XXX_Entry_Desc,
  XXX_DocType,
  XXX_TCode,
  XXX_Company,
  XXX_Posted_By,
  XXX_Parked_By,
  XXX_Accounting_Date,
  XXX_Creation_Date
FROM
  [acl_data.XXX_JE_All_Formatted]
WHERE
  XXX_lnaourj_ID IN (
  SELECT
    XXX_lnaourj_ID
  FROM
    [acl_data.XXX_JE_All_Formatted]
  WHERE
    XXX_Creation_Date - XXX_Accounting_Date > 30
  GROUP BY
    XXX_lnaourj_ID )
ORDER BY
  XXX_lnaourj_ID ASC

如果这不起作用...... Bigquery不是加入的粉丝...... 试试这个：

Select *
 from  
(
Select *, 
max(XXX_Creation_Date - XXX_Accounting_Date) over(partition by  XXX_lnaourj_ID) as maxdatediff
 From [acl_data.XXX_JE_All_Formatted]
) 
where maxdatediff>30

如何在Google BigQuery中重写此查询，而不会导致资源超出错误
