Answer 1

Votre mise à jour utilise si.shi.

Cet alias est uniquement défini dans le CTE. Supprimer l'alias de la mise à jour devrait résoudre l'erreur.

;WITH myCTE AS 
(Select mci.* from 
view_name AS si 
JOIN merch_ctlg_ipt_view_name AS mci 
    ON mci.view_id = si.view_id 
    AND mci.resolved_view_name_id = si.view_name_id 
    AND mci.ctg_ipt_event_id = @ctg_ipt_event_id 
    AND mci.accept_flag = 'y') 

UPDATE view_name 
SET name = (select mci.name from myCTE where myCTE.view_id = view_id) 
,view_name_ctg_id = (select mci.resolved_view_name_ctg_id from myCTE where myCTE.view_id = view_id) 
,xref_value = (select mci.xref_value from myCTE where myCTE.view_id = view_id) 
,availability_start_date = (select mci.availability_start_date from myCTE where myCTE.view_id = view_id) 
,availability_end_date = (select mci.availability_end_date from myCTE where myCTE.view_id = view_id) 
,status_code = (select mci.status_code from myCTE where myCTE.view_id = view_id) 
,last_modified_user_id = (select CASE WHEN mci.last_modified_user_id = 42 THEN @posting_user_id ELSE mci.last_modified_user_id END from myCTE where myCTE.view_id = view_id) 
,last_modified_timestamp = CURRENT_TIMESTAMP 
WHERE shi_flag = 'n' 
and exists (select view_id from merch_ctlg_ipt_view_name AS mci 
    Where mci.view_id = view_name.view_id 
    AND mci.resolved_view_name_id = view_name.view_name_id 
    AND mci.ctg_ipt_event_id = @ctg_ipt_event_id 
    AND mci.accept_flag = 'y') 

Answer 2

Pourquoi le CTE du tout? Cela ne permettrait-il pas d'obtenir la même chose plus clairement?

Edit: Mise à jour avec alias correct pour la déclaration de mise à jour

UPDATE si 
SET name = mci.name 
    ,view_name_ctg_id = mci.resolved_view_name_ctg_id 
    ,xref_value = mci.xref_value 
    ,availability_start_date = mci.availability_start_date 
    ,availability_end_date = mci.availability_end_date 
    ,status_code = mci.status_code 
    ,last_modified_user_id = CASE WHEN mci.last_modified_user_id = 42 THEN @posting_user_id ELSE mci.last_modified_user_id END 
    ,last_modified_timestamp = CURRENT_TIMESTAMP 
FROM view_name as si 
     INNER JOIN 
      merch_ctlg_ipt_view_name as mci 
      ON mci.view_id = si.view_id 
      AND mci.resolved_view_name_id = si.view_name_id 
WHERE mci.ctg_ipt_event_id = @ctg_ipt_event_id 
AND  mci.accept_flag = 'y' 
AND  si.shi_flag = 'n' 

Answer 3

Le problème est avec cette ligne:

WHERE si.shi_flag = 'n' 

Il n'y a pas si alias défini dans la requête de mise à jour.

Est devrait probablement:

WHERE shi_flag = 'n' 

Mise à jour (commentaire suivant)

Vous devez également modifier cette ligne:

SET name = (select mci.name from myCTE where myCTE.view_id = view_id) 

Comme la sous-requête fait référence à un alias qu'il ne déclare pas:

SET name = (select name from myCTE where myCTE.view_id = view_id)
