[英]Table rows with identifying parameter in each row SQL SERVER 2008 into single row
對不起 - 我的問題標題可能與我嘗試這樣做無關。
我在CMS的表中有以下(嗯,類似)
pageID key value
201 title Page 201's title
201 description This is 201
201 author Dave
301 title Page 301's title
301 description This is 301
301 author Bob
正如您可能已經猜到的那樣,我需要的是一個查詢,它將產生:
pageID title description author
201 Page 201's title This is page 201 Dave
301 Page 301's title This is page 301 Bob
如果有人可以提供幫助,我會永遠感激 - 我知道這是“請把代碼寄給我”,但我絕對卡住了。
提前致謝。
Select PageId
, Min( Case When key = 'title' Then Value End ) As Title
, Min( Case When key = 'description' Then Value End ) As Description
, Min( Case When key = 'author' Then Value End ) As Author
From Table
Group By PageId
快速破解可能是
select a.pageID, a.value as Title, b.value as Description, c.value as Author from Table a
left outer join Table b on a.pageID = b.pageID and b.key = 'description'
left outer join Table c on a.pageID = c.pageID and c.key = 'author'
where a.key = 'title'
可能不是最好的解決方案,但它可能對您有用。
