如何从 Microsoft 内容管理服务器 (MCMS) 数据库中提取数据答案

【问题标题】：How to extract data from Microsoft Content Management Server (MCMS) database如何从 Microsoft 内容管理服务器 (MCMS) 数据库中提取数据

【问题描述】：

我需要从 Microsoft 内容管理服务器 (MCMS) 数据库中提取大量数据（> 1000 页）以用于 Sitecore 网站。

我可以看到两个主要选项：

将数据迁移到新的简化数据库并显示新网站上的信息。
将 MCMS 解决方案转换为 SharePoint 并使用 SharePoint 可供 Sitecore 显示此信息的连接器模块。

我更愿意走第一条路线，因为没有计划在未来使用 SharePoint 来管理数据/内容，并且更愿意将此信息存储在一个简单的 SQL Server 数据库中以便更好地进行搜索。

我查看了有问题的数据库，并认为我感兴趣的主要表是 Node、NodePlaceholder 和 NodePlaceholderContent，但我很难找到我所期望的。有人可以为我解释一下这个数据库的架构吗？或者我在尝试以这种方式迁移数据时会遇到问题吗？

【解决方案1】：

我最近刚刚经历了从 MCMS 2002 中导出内容页面的类似过程（迁移到 Wordpress）。

我并不是说这是获取数据的 100% 正确的方法，但它对我有用。

这是我从数据库中获取页面内容的过程。

正如您已经看到的，存储大部分数据的表是 Node 和 NodePlaceholderContent

1.) 要了解Node 表的内容，您可以查看按类型组织的内容

SELECT
    [Type]
    ,CASE [Type] 
        WHEN      1 THEN 'Server'
        WHEN      4 THEN 'Channel'
        WHEN     16 THEN 'Post/Page'
        WHEN     64 THEN 'Resource Gallery'
        WHEN    256 THEN 'Resource Gallery Item (images/documents)'
        WHEN  16384 THEN 'Template Gallery'
        WHEN  65536 THEN 'Template' END as [Description]
    ,COUNT([Type]) as [Count]
FROM        dbo.Node
GROUP BY    [Type]
ORDER BY    [Count] DESC

2.) 页面（和帖子，将在更下方覆盖帖子）的类型 = 16...但要仅获取页面（而不是帖子），我们需要按 IsShortcut = 0 过滤

SELECT * FROM dbo.Node WHERE [Type] = 16 AND IsShortcut = 0

3.) 我只想要已发布的页面，所以按 ApprovalStatus = 1 过滤

-- Get all published pages
SELECT * 
FROM dbo.Node WHERE [Type] = 16 
AND IsShortcut = 0
AND ApprovalStatus = 1

4.) 接下来，确定由（使用用户名）创建/修改的页面

-- Get published pages & author/editor
SELECT 
    [page].Id
    ,[page].NodeGuid
    ,[page].Name
    ,[created].Username as 'CreatedBy'
    ,[page].CreatedWhen
    ,[modified].Username as 'ModifiedBy'
    ,[page].ModifiedWhen
FROM        dbo.Node [page]
-- add JOIN on created by user
INNER JOIN  dbo.ClientAccount [created] ON [created].UserId = [page].CreatedByUserId
-- add JOIN on modified by user
INNER JOIN  dbo.ClientAccount [modified] ON [modified].UserId = [page].ModifiedByUserId
WHERE [Type] = 16 
AND IsShortcut = 0
AND ApprovalStatus = 1

5.) 接下来，使用Node.ParentGUID 列找出我们在层次结构中的位置

SELECT 
    [page].Id
    ,[page].NodeGuid
    ,[page].Name
    ,[pageParent].Name -- add page parent Name
    ,[created].Username as 'CreatedBy'
    ,[page].CreatedWhen
    ,[modified].Username as 'ModifiedBy'
    ,[page].ModifiedWhen
FROM        dbo.Node [page]
INNER JOIN  dbo.ClientAccount [created] ON [created].UserId = [page].CreatedByUserId
INNER JOIN  dbo.ClientAccount [modified] ON [modified].UserId = [page].ModifiedByUserId
-- add JOIN on Node using ParentGUID
INNER JOIN  dbo.Node [pageParent] ON [pageParent].NodeGUID = [page].ParentGUID
WHERE [page].[Type] = 16
AND [page].IsShortcut = 0
AND [page].ApprovalStatus = 1

此查询让我知道页面位于名为 Folders 或 Archive Folder 的父节点中

6.) 再上一层（获取父级的父级）

SELECT 
    [page].Id
    ,[page].NodeGuid
    ,[page].Name
    ,[pageParent].Name 
    ,[pageParent2].Name -- add parent of parent name
    ,[created].Username as 'CreatedBy'
    ,[page].CreatedWhen
    ,[modified].Username as 'ModifiedBy'
    ,[page].ModifiedWhen
FROM        dbo.Node [page]
INNER JOIN  dbo.ClientAccount [created] ON [created].UserId = [page].CreatedByUserId
INNER JOIN  dbo.ClientAccount [modified] ON [modified].UserId = [page].ModifiedByUserId
INNER JOIN  dbo.Node [pageParent] ON [pageParent].NodeGUID = [page].ParentGUID
-- add another JOIN on Node using ParentGUID (parent of parent)
INNER JOIN  dbo.Node [pageParent2] ON [pageParent2].NodeGUID = [pageParent].ParentGUID
WHERE [page].[Type] = 16
AND [page].IsShortcut = 0
AND [page].ApprovalStatus = 1

父级的父级是Server（根级别）所以现在我的结论是如果页面的父级是：

Folders - 那么这是一个活动页面
Archive Folder - 那是另一个页面的先前版本

我只想要活动页面，所以我将只加入 Folders 父级

7.) 现在如何标记。在我们的 MCMS 模板中，只有一个占位符区域。 NodePlaceholder 表将识别占位符的名称，如果您的模板中有多个占位符区域，这将很有帮助。为简单起见，我只会加入 NodePlaceholdercontent。

SELECT 
    [page].Id
    ,[page].NodeGuid
    ,[page].Name
    /* remove parent names */
    ,[created].Username as 'CreatedBy'
    ,[page].CreatedWhen
    ,[modified].Username as 'ModifiedBy'
    ,[page].ModifiedWhen
    ,html.PropValue as 'HTML' -- add the markup
FROM        dbo.Node [page]
INNER JOIN  dbo.ClientAccount [created] ON [created].UserId = [page].CreatedByUserId
INNER JOIN  dbo.ClientAccount [modified] ON [modified].UserId = [page].ModifiedByUserId
-- change alias to "folders"
INNER JOIN  dbo.Node [folders] ON [folders].NodeGUID = [page].ParentGUID AND [folders].Name = 'Folders'
-- join on PlaceholderContent to get the HTML
-- this table will also have references to any static files contained in the page (such as images) so we filter those out by PropName = 'HTML'
INNER JOIN  dbo.NodePlaceholderContent html ON html.NodeId = [page].Id AND html.PropName = 'HTML' 
WHERE [page].[Type] = 16
AND [page].IsShortcut = 0
AND [page].ApprovalStatus = 1

8.) 所以此时我有点卡在试图确定页面在系统中的位置（即相对路径或它所在的频道），回到第 1 步和第 2 步，输入 = 16 可以是帖子或页面（它们不是同一件事，但它们是相关的）。所以现在我们将我们的页面加入到帖子记录中以确定路径。

经过一些谷歌搜索后，我偶然发现了 this excerpt from Microsoft Content Management Server 2002: a complete guide 确实有助于完成剩下的工作（并确定了 Node.Type 枚举）

SELECT 
    [page].Id
    ,[page].NodeGuid
    ,[page].Name
    ,[post].DisplayName as 'Title' -- add page Title from the post record
    ,[pageParent].Name 
    ,[pageParent2].Name
    ,[created].Username as 'CreatedBy'
    ,[page].CreatedWhen
    ,[modified].Username as 'ModifiedBy'
    ,[page].ModifiedWhen
    ,html.PropValue as 'HTML'
FROM        dbo.Node [page]
INNER JOIN  dbo.ClientAccount [created] ON [created].UserId = [page].CreatedByUserId
INNER JOIN  dbo.ClientAccount [modified] ON [modified].UserId = [page].ModifiedByUserId
INNER JOIN  dbo.Node [folders] ON [folders].NodeGUID = [page].ParentGUID AND [folders].Name = 'Folders'
INNER JOIN  dbo.NodePlaceholderContent html ON html.NodeId = [page].Id AND html.PropName = 'HTML' 
-- join using followGUID to get the posting
INNER JOIN  dbo.Node [post] ON [post].FollowGUID = [page].NodeGUID
WHERE [page].[Type] = 16
AND [page].IsShortcut = 0
AND [page].ApprovalStatus = 1

9.) 现在的最后一步是继续向上传递父级层次结构，从而导致多个 LEFT JOINS 逐步提升 ParentGUID 链。此查询使用这些 LEFT JOINS 提供层次结构的可视化表示。

SELECT 
    CASE WHEN postParent9.Name IS NULL THEN '' ELSE postParent9.Name + ' > ' END +
    CASE WHEN postParent8.Name IS NULL THEN '' ELSE postParent8.Name + ' > ' END +
    CASE WHEN postParent7.Name IS NULL THEN '' ELSE postParent7.Name + ' > ' END +
    CASE WHEN postParent6.Name IS NULL THEN '' ELSE postParent6.Name + ' > ' END +
    CASE WHEN postParent5.Name IS NULL THEN '' ELSE postParent5.Name + ' > ' END +
    CASE WHEN postParent4.Name IS NULL THEN '' ELSE postParent4.Name + ' > ' END +
    CASE WHEN postParent3.Name IS NULL THEN '' ELSE postParent3.Name + ' > ' END +
    CASE WHEN postParent2.Name IS NULL THEN '' ELSE postParent2.Name + ' > ' END +
    CASE WHEN postParent1.Name IS NULL THEN '' ELSE postParent1.Name + ' > ' END +
    page.Name as [Path]
    ,page.Name + '.htm' as [PageName]
    ,post.DisplayName as [PageTitle]
    ,CASE page.[Type] 
        WHEN      1 THEN 'Server'
        WHEN      4 THEN 'Channel'
        WHEN     16 THEN 'Post/Page'
        WHEN     64 THEN 'Resource Gallery'
        WHEN    256 THEN 'Resource Gallery Item (images/documents)'
        WHEN  16384 THEN 'Template Gallery'
        WHEN  65536 THEN 'Template' END as [Type]
    ,page.CreatedWhen as 'Created'
    ,page.ModifiedWhen as 'Modified'
    ,html.PropValue as 'HTML'
FROM        dbo.Node page
INNER JOIN  dbo.Node folders ON folders.NodeGUID = page.ParentGUID AND folders.Name = 'Folders'
INNER JOIN  dbo.NodePlaceholderContent html ON html.NodeId = page.Id AND html.PropName = 'HTML'
INNER JOIN  dbo.Node post ON post.FollowGUID = page.NodeGUID AND post.IsShortcut = 1
LEFT JOIN   dbo.Node postParent1 ON postParent1.NodeGuid = post.ParentGUID
LEFT JOIN   dbo.Node postParent2 ON postParent2.NodeGuid = postParent1.ParentGUID
LEFT JOIN   dbo.Node postParent3 ON postParent3.NodeGuid = postParent2.ParentGUID
LEFT JOIN   dbo.Node postParent4 ON postParent4.NodeGuid = postParent3.ParentGUID
LEFT JOIN   dbo.Node postParent5 ON postParent5.NodeGuid = postParent4.ParentGUID
LEFT JOIN   dbo.Node postParent6 ON postParent6.NodeGuid = postParent5.ParentGUID
LEFT JOIN   dbo.Node postParent7 ON postParent7.NodeGuid = postParent6.ParentGUID
LEFT JOIN   dbo.Node postParent8 ON postParent8.NodeGuid = postParent7.ParentGUID
LEFT JOIN   dbo.Node postParent9 ON postParent9.NodeGuid = postParent8.ParentGUID

顺便说一句，我的任务不涉及导出资源库内容（图像/文档/等），但如果您也需要这些部分，这里应该有足够的信息来获得良好的开端。

我希望这对从 MCMS 2002 迁移的其他人有所帮助...
