错误：Teradata执行：计算期间发生数字溢出

我发现了这个错误：Teradata执行：计算过程中发生了数字溢出。

我在这个论坛上已经阅读了类似的问题，但仍然无法理解我应该怎样做才能解决问题。 我认为原因是当我在DEBT_EXPENSE上设置NATIONAL_AMOUNT时，我有计算步骤。

使用CAST后仍无法解决问题。 有没有想过？请帮我。 我认为问题在于：

    EXECUTE (create multiset volatile table Debt_&mon. AS 
    (SELECT 
              t1.TABLE_BUSINESS_MONTH,
              t1.REGION,
              t1.SEGMENT,
              t1.ACC_METH,
              COUNT(t1.ACC_N) as Count_ACC_N,
              SUM(t1.NATIONAL_UNPAID) AS NATIONAL_UNPAID,
              SUM(t1.DEBT_EXPENSE) as DEBT_EXPENSE,
              SUM(t2.NATIONAL_AMOUNT) as NATIONAL_AMOUNT,
              (case when SUM(t2.NATIONAL_AMOUNT)=0 then 0 else (cast(SUM(t1.DEBT_EXPENSE) as Decimal(20,6))/cast(SUM(t2.NATIONAL_AMOUNT) as Decimal(20,6)) end) as 'РСДЗ/Д'n,
              (case when SUM(t1.DEBT_EXPENSE)=0 then 0 else cast(SUM(t2.NATIONAL_AMOUNT) as Decimal(20,6))/cast(SUM(t1.DEBT_EXPENSE) as Decimal(20,6)) end) as 'Д/ДЗ'n

           FROM Prev_Debt_&mon. t1
           LEFT JOIN CLC_&mon. t2 on 
                t1.REGION=t2.REGION and

           GROUP BY t1.TABLE_BUSINESS_MONTH, t1.REGION, t1.SEGMENT, t1.ACC_METH)

    WITH DATA NO PRIMARY INDEX ON COMMIT PRESERVE ROWS;)

答案 0 :(得分：0)

在投射数字列时使用Bigint而不是INTEGER？DECIMAL

答案 1 :(得分：0)

Actualy，我找到了如何解决我的问题。除了完整的代码，我把代码带到了我遇到麻烦的地方。 日志出错“计算过程中发生数字溢出”。但感到麻烦的是列NATIONAL_AMOUNT。 然后我在SUM(t2.NATIONAL_AMOUNT) as NATIONAL_AMOUNT,上更改了t2.NATIONAL_AMOUNT。 在那段代码起作用之后。

我在上一步中对t2.NATIONAL_AMOUNT进行了重新聚集，我不应该再对它进行两次。
