转置查询创建节点 (SQL Server 2008) [英] Transpose query creates nodes (SQL Server 2008)

问题描述

我终于找到了要执行的查询，以获取一行中一个内容的所有 id(逗号分隔).

I finally found the query to execute to get all ids (comma separated) for one content in one row.

以下查询成功了:

您不需要查看查询，因为它已经做了它应该做的事情.

You don't need to look at the query because it already does what it should do.

SELECT 
    taxonomy_item_id, 
    SUBSTRING(
      (SELECT ', ' + CAST(taxonomy_id AS varchar) AS Expr1
       FROM taxonomy_item_tbl AS t2
       WHERE (t1.taxonomy_item_id = taxonomy_item_id) AND (taxonomy_language_id = 2067)
       ORDER BY taxonomy_item_id, taxonomy_id FOR XML PATH('')
      ), 1, 1000) AS taxonomy_ids
FROM 
    taxonomy_item_tbl AS t1
WHERE 
    (taxonomy_language_id = 2067) AND (taxonomy_item_id = 180555)
GROUP BY 
    taxonomy_item_id

唯一的问题是我得到的数据结果:

The only problem is the data result I get:

180555  |   <Expr1>, 404</Expr1><Expr1>, 405</Expr1><Expr1>, 723</Expr1><Expr1>, 1086</Expr1><Expr1>, 1087</Expr1><Expr1>, 1118</Expr1><Expr1>, 1124</Expr1><Expr1>, 1126</Expr1>

我不需要 节点.有没有办法删除这个?如果我在查询中删除 AS Expr1 然后它会自动添加回来

I don't need the <Expr1> nodes. Is there a way to delete this? If I delete AS Expr1in the query then it is automatically added back

谢谢

推荐答案

如果您不想要 - 那么就不要要求它！

If you don't want the <Expr1> - then just don't ask for it!

你有:

(SELECT ', ' + CAST(taxonomy_id AS varchar) AS Expr1

那个 AS Expr1 导致 被添加 - 所以不要在那里有那个表达式.

That AS Expr1 causes the <Expr1> to be added - so just don't have that expression there.

试试

SELECT 
    taxonomy_item_id, 
    SUBSTRING(
      (SELECT ', ' + CAST(taxonomy_id AS VARCHAR) 
       FROM dbo.taxonomy_item_tbl AS t2
       WHERE t1.taxonomy_item_id = taxonomy_item_id
       AND taxonomy_language_id = 2067
       ORDER BY taxonomy_item_id, taxonomy_id 
       FOR XML PATH('')
      ), 1, 1000) AS taxonomy_ids
FROM 
    dbo.taxonomy_item_tbl AS t1
WHERE 
    taxonomy_language_id = 2067
    AND taxonomy_item_id = 180555
GROUP BY 
    taxonomy_item_id
