SHORTEST_PATH 在某些图表中具有多个节点和一条边

Question

I have three tables to design actors paying in movies (films):

-- actors node table :
CREATE TABLE T_ACTEUR_ACT
(ACT_ID        INT PRIMARY KEY,
 ACT_PRENOM    VARCHAR(32),
 ACT_NOM       VARCHAR(50)) AS NODE;

-- movies node table (films)
CREATE TABLE T_FILM_FLM
(FLM_ID        INT PRIMARY KEY,
 FLM_TITRE     VARCHAR(250),
 FLM_ANNEE     SMALLINT) AS NODE;

-- playing edge
CREATE TABLE T_JOUE_JOU (JOU_INTERPRETE VARCHAR(250)) AS EDGE;
GO

I would like to know how to write a Graph Query to find the shortest social distance between Cary Grant and James Mason...

Every queries I have tried does not work...

SELECT ACTOR, chemin, Q.LastNode AS FRIEND
FROM
(
SELECT acteur0.ACT_PRENOM + acteur0.ACT_NOM AS ACTOR, 
         STRING_AGG(CONCAT(acteurN.ACT_PRENOM, ' ', acteurN.ACT_NOM), '->') 
          WITHIN GROUP (GRAPH PATH) AS chemin,
         LAST_VALUE(CONCAT(acteurN.ACT_PRENOM, ' ', acteurN.ACT_NOM)) 
          WITHIN GROUP (GRAPH PATH) AS LastNode
FROM   T_ACTEUR_ACT AS acteur0,
         T_JOUE_JOU FOR PATH AS joue,
       T_FILM_FLM FOR PATH as film,
       T_JOUE_JOU FOR PATH AS joue2,
         T_ACTEUR_ACT FOR PATH AS acteurN
WHERE  MATCH(SHORTEST_PATH( acteur0 ( - (joue) -> film - (joue2) -> acteurN ) + ) )
  AND  acteur0.ACT_PRENOM = 'Cary' AND acteur0.ACT_NOM = 'Grant'
  AND  acteurN.ACT_PRENOM <> 'Cary' AND acteurN.ACT_NOM <> 'Grant'
) AS G
WHERE G.LastNode = 'James Mason'

The result is 3exceptions:

Msg 13961, Niveau 16, État 1...

The alias or identifier 'acteurN.ACT_PRENOM' cannot be used in the select list, order by, group by, or having context.

Msg 13961, Niveau 16, État 1...

The alias or identifier 'acteurN.ACT_NOM' cannot be used in the select list, order by, group by, or having context.

Thoses are relative to the last two rows or the subquery...

Msg 4104, Niveau 16, État 1, Ligne ...

The multi-part identifier "Q.LastNode" could not be bound.

I have try another approach for the subquery:

SELECT acteur0.ACT_PRENOM, acteur0.ACT_NOM, 
         STRING_AGG(CONCAT(acteurN.ACT_PRENOM, ' ', acteurN.ACT_NOM), '->') 
          WITHIN GROUP (GRAPH PATH) AS chemin,
         LAST_VALUE(CONCAT(acteurN.ACT_PRENOM, ' ', acteurN.ACT_NOM)) 
          WITHIN GROUP (GRAPH PATH) AS LastNode
FROM   T_ACTEUR_ACT AS acteur0,
         T_JOUE_JOU FOR PATH AS joue,
       T_FILM_FLM FOR PATH as film,
       T_JOUE_JOU FOR PATH AS joue2,
         T_ACTEUR_ACT FOR PATH AS acteurN
WHERE  MATCH(SHORTEST_PATH(acteur0 ( - (joue) -> film)+)
             AND 
             SHORTEST_PATH(LAST_NODE(film)(-(joue2) -> acteurN)+))
    AND acteur0.ACT_PRENOM = 'Cary' AND acteur0.ACT_NOM = 'Grant'
   AND acteurN.ACT_PRENOM <> 'Cary' AND acteurN.ACT_NOM <> 'Grant'

But the same two exceptions (The alias or identifier... cannot be used in the select list...)

Here is my test set:

Answer 1

The answer given by @lptr is good !

I just simplify as:

WITH
T_SEARCH_PATH AS
(
SELECT acteur0.ACT_PRENOM + ' '+ acteur0.ACT_NOM AS ACTOR, 
       STRING_AGG(CONCAT(acteurN.ACT_PRENOM, ' ', acteurN.ACT_NOM, ' : ', film.FLM_TITRE), ' -> ') 
          WITHIN GROUP (GRAPH PATH) AS path_to,
       LAST_VALUE(CONCAT(acteurN.ACT_PRENOM, ' ', acteurN.ACT_NOM)) 
          WITHIN GROUP (GRAPH PATH) AS LastNode
FROM   T_ACTEUR_ACT AS acteur0,
       T_JOUE_JOU FOR PATH AS joue,
       T_FILM_FLM FOR PATH as film,
       T_JOUE_JOU FOR PATH AS joue2,
       T_ACTEUR_ACT FOR PATH AS acteurN
WHERE  MATCH(SHORTEST_PATH( acteur0 ( - (joue) -> film - (joue2) -> acteurN ) + ) )
  AND  acteur0.ACT_PRENOM = 'Cary' AND acteur0.ACT_NOM = 'Grant'
)
SELECT ACTOR, path_to, LastNode AS FRIEND
FROM   T_SEARCH_PATH
WHERE  LastNode = 'Gregory Peck';

Which give me an answer like:

ACTOR        path_to                                                                          FRIEND
