列と手順の値を比較します

Question

評価する値のリストがあります。例では、私は、ストアドプロシージャの出力が1列と4列エイリアス左外側から返され得る参加を有する

'16-%', '45-%','A1%','125%' 

の下方に設けられ

例：

Max(db_util.Efn_name_wid(tdl_tran.reason_code_id, 
       remit_rmc.remit_code_id, remit_rmc.remit_code_name, 'Reason') 
) AS DEN_REASON 

, Max(RMC_1.remit_code_name) 
     AS REMIT_CD1 

,Max(RMC_2.remit_code_name) 
     AS REMIT_CD2 

,Max(RMC_3.remit_code_name) 
     AS REMIT_CD3 

,Max(RMC_4.remit_code_name) 
     AS REMIT_CD4 

ロジックIビルドしようとしています：

IF DEN_REASONのような（リストの任意の値）

次に、同じリストに対してremit_cd1の列を評価します（リスト内の値と一致する場合）。次に、remit_cd2、remit_cd3、remit_cd4に進み、リスト内の値と一致しない最初の送金コードを見つけます。

最終的に1つの値を返そうとしています。私はこのCASE文は何が必要かもしれないと思う

Answer 1

：あなたは、サブクエリであなたのLIKE試用版をやった場合

SELECT CASE 
    WHEN DEN_REASON LIKE (/* your set of values */) 
     AND REMIT_CD1 LIKE (/* your set of values */) 
     AND REMIT_CD2 LIKE (/* your set of values */) 
     AND REMIT_CD3 LIKE (/* your set of values */) 
     AND REMIT_CD4 NOT LIKE (/* your set of values */) 
     THEN REMIT_CD4 
    WHEN DEN_REASON LIKE (/* your set of values */) 
     AND REMIT_CD1 LIKE (/* your set of values */) 
     AND REMIT_CD2 LIKE (/* your set of values */) 
     AND REMIT_CD3 NOT LIKE (/* your set of values */) 
     THEN REMIT_CD3 
    WHEN DEN_REASON LIKE (/* your set of values */) 
     AND REMIT_CD1 LIKE (/* your set of values */) 
     AND REMIT_CD2 NOT LIKE (/* your set of values */) 
     THEN REMIT_CD2 
    WHEN DEN_REASON LIKE (/* your set of values */) 
     AND REMIT_CD1 NOT LIKE (/* your set of values */) 
     THEN REMIT_CD1 
    WHEN DEN_REASON NOT LIKE (/* your set of values */) 
     THEN DEN_REASON 
    END AS YourSingleResult 

FROM --your query 
( SELECT 
    Max(db_util.Efn_name_wid(tdl_tran.reason_code_id, 
     remit_rmc.remit_code_id, remit_rmc.remit_code_name, 'Reason') 
     ) AS DEN_REASON 
    ,Max(RMC_1.remit_code_name) AS REMIT_CD1 
    ,Max(RMC_2.remit_code_name) AS REMIT_CD2 
    ,Max(RMC_3.remit_code_name) AS REMIT_CD3 
    ,Max(RMC_4.remit_code_name) AS REMIT_CD4 
    -- and the rest of your query, that you omitted from your example above 
) 

はその後、再び、それは短いかもしれません。このように：

SELECT CASE 
    WHEN MatchesDenReason = 1 
     AND MatchesCD1 = 1 
     AND MatchesCD2 = 1 
     AND MatchesCD3 = 1 
     AND MatchesCD4 = 0 
     THEN REMIT_CD4 
    WHEN MatchesDenReason = 1 
     AND MatchesCD1 = 1 
     AND MatchesCD2 = 1 
     AND MatchesCD3 = 0 
     THEN REMIT_CD3 
    WHEN MatchesDenReason = 1 
     AND MatchesCD1 = 1 
     AND MatchesCD2 = 0 
     THEN REMIT_CD2 
    WHEN MatchesDenReason = 1 
     AND MatchesCD1 = 0 
     THEN REMIT_CD1 
    WHEN MatchesDenReason = 0 
     THEN DEN_REASON 
    END AS YourSingleResult 

FROM --your query 
( SELECT 
    Max(db_util.Efn_name_wid(tdl_tran.reason_code_id, 
     remit_rmc.remit_code_id, remit_rmc.remit_code_name, 'Reason') 
     ) AS DEN_REASON 
    ,CASE WHEN Max(db_util.Efn_name_wid(tdl_tran.reason_code_id, 
     remit_rmc.remit_code_id, remit_rmc.remit_code_name, 'Reason') 
     ) LIKE (/* your list */) 
      THEN 1 ELSE 0 END AS MatchesDenReason 
    ,Max(RMC_1.remit_code_name) AS REMIT_CD1 
    ,CASE WHEN Max(RMC_1.remit_code_name) LIKE (/* your list */) 
      THEN 1 ELSE 0 END AS MatchesCD1 
    ,Max(RMC_2.remit_code_name) AS REMIT_CD2 
    ,CASE WHEN Max(RMC_2.remit_code_name) LIKE (/* your list */) 
      THEN 1 ELSE 0 END AS MatchesCD2 
    ,Max(RMC_3.remit_code_name) AS REMIT_CD3 
    ,CASE WHEN Max(RMC_3.remit_code_name) LIKE (/* your list */) 
      THEN 1 ELSE 0 END AS MatchesCD3 
    ,Max(RMC_4.remit_code_name) AS REMIT_CD4 
    ,CASE WHEN Max(RMC_4.remit_code_name) LIKE (/* your list */) 
      THEN 1 ELSE 0 END AS MatchesCD4 
    -- and the rest of your query, that you omitted from your example above
