我收到错误，如下所示：

无法绑定多部分标识符“si.shi”。

执行此SQL时：

;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 si.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')

以下是视图和表格的结构：

请帮忙

问题在于这一行：

WHERE si.shi_flag = 'n'

更新查询中未定义si别名。

应该是：

WHERE shi_flag = 'n'

更新（以下评论）

您还应该更改此行：

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

由于子查询引用了一个未声明的别名：

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

您的更新使用si.shi。

此别名仅在CTE中定义。从更新中删除别名应该可以解决错误。

;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')

答案 2 :(得分：0)

为什么选择CTE？这会不会更清楚地达到同样的目的吗？

编辑：更新了更新语句的正确别名

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'
