De retour une ligne d'une clause

Question

Je suis en train de faire une fonction qui retruns une valeur.

Dans ma fonction, j'ai ce script:

WITH t_new AS
    (
      SELECT PersIDOLD, PersIDNEW, RightsMUT,
      SUM(gap) over(ORDER BY PersIDOLD, PersIDNEW) grp

      FROM
        (
          SELECT h1.*,
            CASE
              WHEN h1.PersIDNEW = lag(h1.PersIDNEW) 
                                    over(ORDER BY h1.PersIDOLD, h1.PersIDNEW)
                OR h1.PersIDOLD = lag(h1.PersIDOLD) 
                                    over(ORDER BY h1.PersIDOLD, h1.PersIDNEW)
              THEN 0
              ELSE 1
            END gap
          FROM HelpTable1 h1

        )
    )
  SELECT PERSIDNEW, RIGHTSMUT
  FROM t_new
  WHERE grp =
    (
      SELECT grp FROM t_new WHERE PersIDNEW = 12 -- going to be a variable
    )

le retour est comme ceci:

Maintenant, je veux revenir row 3 Coze il a une 1 dans la ligne RightsMUT

Comment pourrais-je faire cela? J'ai essayé de le faire avec 2 With mais Oracle ne supporte pas 2 avec encore.

Ma solution:

  WITH t_new AS
    (
      -- Alles durch gehen und
      SELECT PersIDOLD, PersIDNEW, RightsMUT, SUM(gap) over(ORDER BY PersIDOLD, PersIDNEW) grp
      FROM
        (
          SELECT h1.*,
            CASE
              WHEN h1.PersIDNEW = lag(h1.PersIDNEW) over(ORDER BY h1.PersIDOLD, h1.PersIDNEW)
                OR h1.PersIDOLD = lag(h1.PersIDOLD) over(ORDER BY h1.PersIDOLD, h1.PersIDNEW)
              THEN 0
              ELSE 1
            END gap
          FROM LUTAXKT.HILFSTABELLE1UMSETZUNG h1
            --WHERE h1.updateflag = 0
        )
    )
  SELECT PersIDNEW, RightsMUT
  FROM t_new
  WHERE  RightsMUT = 1 and
   grp =
    (
      SELECT grp FROM t_new WHERE PersIDNEW = 12
    )

Je vais essayer de deviner - pls vérifier si ce qui suit vous donne ce que vous avez besoin:

WITH t_new AS
(
  SELECT PersIDOLD, PersIDNEW, RightsMUT,
  SUM(gap) over(ORDER BY PersIDOLD, PersIDNEW) grp

  FROM
    (
      SELECT h1.*,
        CASE
          WHEN h1.PersIDNEW = lag(h1.PersIDNEW) 
                                over(ORDER BY h1.PersIDOLD, h1.PersIDNEW)
            OR h1.PersIDOLD = lag(h1.PersIDOLD) 
                                over(ORDER BY h1.PersIDOLD, h1.PersIDNEW)
          THEN 0
          ELSE 1
        END gap
      FROM HelpTable1 h1

    )
) 
SELECT PERSIDNEW, RIGHTSMUT
FROM t_new
WHERE PersIDNEW = 12 AND RightsMUT = 1
