ELSE IFは、where句のSQL Serverの

に私は3つのテーブルrds、 rds_distr、productを持っているし、rds_distr_cd = 'A'ならば、私は他に一つだけの行残りの行を表示したい意味条件where句をやろうとしています。ELSE IFは、where句のSQL Serverの

テーブル構造のスクリプトと一部のデータ - rds_distr_cdは0のみである場合

rds_cd  prod_cd  rds_distr_cd 
INMHA142 DEN101050001 0 
INMHM129 DEN101050001 1

そして、私が欲しい -

select rds_cd, prod_cd,rds_distr_cd from 
(select distinct r.rds_cd,prod_cd,case when r.rds_distr_cd = 'A' then 0 when r.rds_distr_cd = 'B' then 1 when r.rds_distr_cd = 'P' THEN 2 END AS rds_distr_cd 
           from product p,rds r left join rds_distr rd on r.rds_cd = rd.rds_cd 
           where r.rds_distr_cd ='A' 
           AND (r.rds_cd in ('INMHA142','INMHK083','INMHM129') 
           and p.prod_cd in ('DEN101050001') 
           ) 
           OR (r.rds_distr_cd in ('B','p') 
           AND r.rds_cd = rd.rds_cd 
           and (rd.prod_brand_cd =p.prod_brand_cd 
           or rd.prod_line_cd = p.prod_line_cd) 
           and r.rds_cd in ('INMHA142','INMHK083','INMHM129') 
           and p.prod_cd in ('DEN101050001') 
           )) as a 
           where rds_distr_cd = IIF(rds_distr_cd = 0,0,0) 
           OR rds_distr_cd =IIF(rds_distr_cd = 1,1,1)

where句には、両方ともAND & ORという複数の条件があります。括弧を正しく使用しない限り、期待どおりに動作しません。

はこれにあなたの where句を変更

：

where r.rds_distr_cd ='A' 
    AND ((r.rds_cd in ('INMHA142','INMHK083','INMHM129') 
      and p.prod_cd in ('DEN101050001') 
     ) 
     OR (r.rds_distr_cd in ('B','p') 
      AND r.rds_cd = rd.rds_cd 
      and (rd.prod_brand_cd =p.prod_brand_cd 
        or rd.prod_line_cd = p.prod_line_cd 
       ) 
      and r.rds_cd in ('INMHA142','INMHK083','INMHM129') 
      and p.prod_cd in ('DEN101050001') 
      ) 
     )

変更を：（AND内部の）第二の条件の一部としてOR含まれています。

感謝を得たが、「A」のレコードがない場合、それはすべてのレコードを与えていません。それは2番目のレコードを与える必要があります。 – Anagha

この状態では、 – Anagha

からrds 'INMHA142'を削除してください。@Anagha：これは、適切に括弧を使用することを指摘していました。あなたのロジックに従って 'where'節を変更してください。 –
