问题描述
我正在与一个菜单结构的网站上工作，以便它可以读取来自多个表下方的子菜单是示例菜单示例
我有几个表像pg_Pages，art_Article，art_Categories，杂志每个表都有一个FK PAGEID在pg_Pages表PK。
我想创建一个SQL查询，将读取从这些表中的数据，并创建分层菜单结构与每个链接指向正确的页面。
我可能需要通过多个查询字符串作为HREF的一部分，如 PAGEID，LanguageID，IssueID和类别ID
样本连接
首页= Default.aspx的LanguageId = 1＆安培; IssueID = 101安培; PAGEID = 1
关于我们= Page.aspx LanguageId = 1＆安培; IssueID = 101安培; PAGEID = 2
分类=文章 - Category.aspx LanguageId = 1＆安培; IssueID = 101安培; PAGEID = 6
- 政治=文章 - Category.aspx LanguageId = 1＆安培; IssueID = 101安培; PAGEID = 6＆安培;类别id = 1
- 经济=文章 - Category.aspx LanguageId = 1＆安培; IssueID = 101安培; PAGEID = 6＆安培;类别ID = 2
- 商务=文章 - Category.aspx LanguageId = 1＆安培; IssueID = 101安培; PAGEID = 6＆安培;类别id = 16
多媒体= Multimedia.aspx LanguageId = 1＆安培; IssueID = 101安培; PAGEID = 10
- 视频= Video.aspx LanguageId = 1＆安培; IssueID = 101安培; PAGEID = 11
我不知道如何最好的方式与容不得一点差错处理这个问题，因为我已经通过不同的查询字符串，以不同的菜单我感到有点困惑如何处理这种方法，我应该创建一个联盟的多个SQL查询处理这种或不同的东西。我需要这个了一个asp.net网站
我还增加了样品的SQL查询，＆安培;每个表输出
SQL
SELECT的PageId AS PARENTID，SUBSTRING（页面名称，0,20）AS PARENT_MENU，SUBSTRING（PageInternalLinkURL，0,24）AS页面处理器，PageLinkPosition，SUBSTRING（PageLayoutPosition，0,14）AS MENU_Type，PageLangID，PageInheritance FROM pg_PagesSELECT p.PageID为PARENTID，SUBSTRING（c.ArticleCategoryName，0,20）AS CHILD_MENU，SUBSTRING（p.PageInternalLinkURL，0,24）AS页面处理器，ArticlePostion，AS条款ArticleID childID的，c.ArticleCategoryID，IssueID，LanguageID FROM art_Articles一个JOIN art_Category C对a.ArticleCategoryID = c.ArticleCategoryID

I am working on a website with a menu structure so that it can read submenus from multiple table below is Sample Menu example
I have several table like pg_Pages, art_Article, art_Categories, Magazine each table has a FK PageID with PK in pg_Pages table.
I want to create a sql query which will read data from these tables and create a hierarchical Menu Structure with each link pointing to correct page.
I may need to pass several query string as part of href such as PageID, LanguageID, IssueID and CategoryID
Sample Link
Home = Default.aspx?LanguageId=1&IssueID=101&PageID=1
About Us = Page.aspx?LanguageId=1&IssueID=101&PageID=2
Categories = Article-Category.aspx?LanguageId=1&IssueID=101&PageID=6
--Politics = Article-Category.aspx?LanguageId=1&IssueID=101&PageID=6&CategoryID=1
--Economy= Article-Category.aspx?LanguageId=1&IssueID=101&PageID=6&CategoryID=2
--Business= Article-Category.aspx?LanguageId=1&IssueID=101&PageID=6&CategoryID=16
Multimedia = Multimedia.aspx?LanguageId=1&IssueID=101&PageID=10
--Video= Video.aspx?LanguageId=1&IssueID=101&PageID=11
I am not sure how handle this in best manner with no room for error, Since i have to pass different query-string to different menu i am bit confused how to handle this approach, should i create a multiple sql query with Union to handle this or something different. I need this for an asp.net website
I have also added sample sql query, & Output from each table
SQL
SELECT PageId AS ParentID,SUBSTRING(PageName,0,20) AS PARENT_MENU,SUBSTRING(PageInternalLinkURL,0,24) AS PageHandler, PageLinkPosition,SUBSTRING(PageLayoutPosition,0,14) AS MENU_Type,PageLangID,PageInheritance FROM pg_Pages
SELECT p.PageID as ParentID, SUBSTRING(c.ArticleCategoryName,0,20) AS CHILD_MENU,SUBSTRING(p.PageInternalLinkURL,0,24) AS PageHandler, ArticlePostion,ArticleID AS CHILDID,c.ArticleCategoryID,IssueID,LanguageID FROM art_Articles a JOIN art_Category c ON a.ArticleCategoryID = c.ArticleCategoryID
JOIN pg_pages p ON p.PageID = a.PageID
SELECT p.PageID AS ParentID, IssueCode as CHILD_MENU,SUBSTRING(p.PageInternalLinkURL,0,24) AS PageHandler, m.IssueCode,IssueID AS CHILDID,CurrentIssue,IssueDate,LangID FROM Magazine m JOIN pg_pages p ON m.PageID = p.PageID
SELECT p.PageID AS ParentID, SUBSTRING(c.ArticleCategoryName,0,20) AS CHILD_MENU,SUBSTRING(p.PageInternalLinkURL,0,24) AS PageHandler, LangID,ArticleCategoryID AS CHILDID FROM art_Category c JOIN pg_Pages p ON c.PageID = p.PageID
OUTPUT
ParentID PARENT_MENU PageHandler PageLinkPosition MENU_Type PageLangID PageInheritance
