在工作中接触了一些SharePoint的数据库中的一些表。在此做个总结。
一位高手告诉我了与Content Database相关的三个表：
AllUserData AllDocs AllDocStreams
我就是从这三个表开始研究的。而且在研究中发现 AllLists 表也很重要，但遗憾的是没在msdn上找到对这个表的说明。
表中每列的含义我就不多说了，在msdn上都有。 我在此举几个例子来介绍一下这些表的使用。
1. 得到用户上传的文档的数目：
select count(*) as DocNumber from dbo.AllDocs
where [ExtensionForFile] <> '' and [DoclibRowId] > 0 and [ListId] in
(select [tp_ID] from dbo.AllLists where [tp_ServerTemplate] = 101 and [tp_ItemCount] > 0)
注：AllLists列表中记录着所有列表的信息，此处所说的列表指的是所有SPList对象。
2. 得到每个文档的平均大小：
--declare variables
declare @file_size int
set @file_size = 0
set @file_size = (select sum(Cast([Size] as bigint)) as DocSize from dbo.AllDocs
where [ExtensionForFile] <> '' and [DoclibRowId] > 0 and [ListId] in
(select [tp_ID] from dbo.AllLists where [tp_ServerTemplate] = 101 and [tp_ItemCount] > 0))
set @file_size = @file_size / 1024
print(@file_size);
注：[Size]字段是以Byte为单位的，所以要将其变为bigint类型。
3. 得到文档库中文档的格式及相应的数目：
select [ExtensionForFile], count(*) as FileCount from dbo.AllDocs
where [ExtensionForFile] <> '' and [DoclibRowId] > 0 and [ListId] in
(select [tp_ID] from dbo.AllLists where [tp_ServerTemplate] = 101 and [tp_ItemCount] > 0)
group by [ExtensionForFile] order by [FileCount] desc
1. 得到文档库的大小
dbo.Webs 记录了每个 SPWeb对象的 FullUrl和 Guid.
dbo.Sites 记录了每个 SPSite对象的 GUID，可以与 dbo.Webs、 dbo.AllDocs对象联合起来使用。
select [ListId] as [LibId], [tp_Title] as [LibTitle],dbo.Webs.[FullUrl], (sum(Cast([Size] as bigint)) / (1024)) as [LibSize (KB)]
from dbo.AllDocs, dbo.AllLists, dbo.Webs
where [ExtensionForFile] <> '' and [DoclibRowId] > 0 and [ListId] = [tp_ID] and
[tp_ServerTemplate] in (101,109,111,113,114,115,116,119) and [tp_ItemCount] > 0 and dbo.AllDocs.[SiteId]=
(select dbo.Sites.[Id] from dbo.Sites, dbo.Webs
where dbo.Webs.[SiteId] = dbo.Sites.Id and dbo.Webs.[FullUrl] = '')
and dbo.AllDocs.[WebId] = dbo.Webs.[Id]
Group By [ListId], dbo.Webs.[FullUrl], [tp_Title] order by [LibSize (KB)] desc
注: dbo.Webs.[FullUrl] 列存储了每个 SPWeb 对象的 url 地址 ( 例如： Teams/Test0223PM0400) ，当此 SPWeb 对象是根站点的 web 对象时，此处值为空字符串。
2. 得到在某段时间内更新的文档数
--declare variables
declare @start_time datetime, @end_time datetime
--set UTC DateTime
set @start_time = cast('2010-12-27 08:08:33' as datetime)
set @end_time = cast('2010-12-28 02:35:21' as datetime)
select count(*) from dbo.AllDocs
where [ExtensionForFile] <> '' and [DoclibRowId] > 0 and [ListId] in
(select [tp_ID] from dbo.AllLists where [tp_ServerTemplate] = 101 and [tp_ItemCount] > 0)
and ([MetaInfoTimeLastModified] between @start_time and @end_time)
注：dbo.AllDocs 表中的 [TimeCreated], [TimeLastModified], [NextToLastTimeModified], [MetaInfoTimeLastModified], 以及 [TimeLastWritten] 列都使用 UTC 时间。
3. 得到最常使用的文档格式及数目
select [ExtensionForFile], count(*) as 'AttachmentCount' from AllDocs
where DoclibRowId is null and [DeleteTransactionId] = 0x and [Type] = 0
and [HasStream] = 1 and ListId in
(select tp_ID from dbo.AllLists where [tp_ServerTemplate] in (100,107,108,150,1100) and [tp_ItemCount] > 0)
group by [ExtensionForFile] order by [AttachmentCount] desc
注： [DeleteTransactionId] 指示该listitem是否已被删除，未删除则值应为0x。
[HasStream] 指示此item是否含有文件流，1表示含有。
[Type] 指示此文档的‘Document Store Type’, 0表示文件，1表示文件夹。
4. 从站点集的Url地址得到所在数据库的名字
此处需要用到SharePoint的配置数据库(默认名称为：SharePoint_Config )
select dbo.objects.[name] from dbo.objects, dbo.sitemap
where dbo.objects.[ID] = dbo.sitemap.[databaseID] and dbo.sitemap.[path] = '/AK/StrategicIndustries'
注：dbo.objects.[name] –> 数据库的名称存在于此列。
dbo.sitemap.[path] –> 记录着站点集的路径。
