エラー：Teradata実行：計算中に数値オーバーフローが発生しました

Question

このエラーが発生しました：Teradata execute：計算中に数値のオーバーフローが発生しました。

このフォーラムでも同様の質問を読みましたが、問題を解決するために何をすべきか理解できません。 私は、DEBT_EXPENSEにNATIONAL_AMOUNTを割り振ったときに、私はステップ上の計算を持っているという理由が考えられました。

CASTを使用した後でも解決はありませんでした。 誰も考えていますか？私を助けてください。 私は問題がここにあると思う：

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

Answer 1

使用BIGINT？DECIMALあなたの数値列をキャストしながら、

Answer 2

実際、私は自分の問題を解決する方法を見つけました。私は完全なコードから離れて問題を抱えていた私のコードを取った。 ログに「計算中に数値のオーバーフローが発生しました」というエラーが発生しました。問題はコラムNATIONAL_AMOUNTであることを嘆いた。 その後、SUM(t2.NATIONAL_AMOUNT) as NATIONAL_AMOUNT,をt2.NATIONAL_AMOUNTに変更しました。 そのコードが機能した後。

私は前のステップで私のt2.NATIONAL_AMOUNTを集計しました。私はそれを2回同意してはいけません。
