我正在处理一个 FileNet 项目，我需要在一个名为 Others 的文件夹中显示文档的数量。我可以通过 CE API 轻松做到这一点，但我需要知道这些信息在 FileNet DB 中的存储位置。
我可以从名为DocVersion 的表中获取文档计数，文件夹信息存储在Container 表中。我需要的是这样的查询：
SELECT COUNT(*) FROM DOCVERSION D, CONTAINER C WHERE --container name is 'Others'
任何帮助将不胜感激。

你是对的。文档放在 DocVersion 中，文件夹放在 Container 表中。但是放置在关系表中的文档和文件夹之间的链接。
如果您使用 FileNet API，您可以尝试使用下一个 FN 查询
Select d.Id from Document d
where d.This INFOLDER '/bla/bla/bla'
或 INSUBFOLDER 运算符。在下一步中，您将需要计算结果集。
如果你想直接从数据库中获取信息，你可以尝试使用下一个查询。
select count(r.Object_Id) from DocVersion d, Container c, Relationship r
where r.Head_Id = c.Object_Id
and d.Object_Id = r.Tail_Id --// you can exclude this if in the Folder filed only documents and not custom objects.
and c.Object_Id = {folder-id} --// or use c.Name = 'Other' - you can't use PathName field in DB query.

感谢您的询问，我已经尝试过了。您的查询中有一个问题。您以错误的方向使用了 head_id 和 tail_id。正确的查询应该如下。
select count(r.Object_Id)
from DocVersion d, Container c, Relationship r
where r.Tail_Id = c.Object_Id and d.Object_Id = r.Head_Id --// you can exclude this if in the Folder filed only documents and not custom objects.
and c.Object_Id = {folder-id} --// or use c.Name = 'Other' - you can't use PathName field in DB query.

我还没有尝试过应用程序中的代码，但是，它会像..
SELECT count (*) as Row_Count
FROM Container c, DocVersion d
WHERE c.object_id = d.object_class_id
AND c.name = 'Others'
希望这对您的想法有所帮助。

这些是获取特定文件夹中文档总量的正确查询...
db2 "select count(*) from OSDBUSER.Relationship r, OSDBUSER.Container c, OSDBUSER.DOCVERSION d where r.Tail_Id = c.Object_Id and r.Head_Id = d.Object_Id and c.name = 'Error'"
在此查询中，“错误”是要计算文档数的文件夹的名称......
【讨论】：
这里有更多示例，用于直接 DB 查询（不是 ACCE/FEM SQL）来查找未归档的文档，但可以更改为查找特定文件夹中归档的对象。 （将where rel.Head_id IS NULL 更改为您的文件夹）
在 MS SQL 上测试和运行。
--Count by Doc Class
SELECT Doc.object_class_id, count(distinct Doc.version_series_id) as '# Docs' , ClassDef.symbolic_name as ClassName
FROM DocVersion doc
LEFT JOIN Relationship rel ON doc.object_id = rel.Head_id
INNER JOIN ClassDefinition ClassDef ON doc.object_class_id = ClassDef.[object_id]
where rel.Head_id IS NULL and doc.is_current=1
group by Doc.object_class_id, ClassDef.symbolic_name
order by '# Docs' desc
--by creator
SELECT Doc.creator, count(distinct Doc.version_series_id) as '# Docs'
FROM DocVersion doc
LEFT JOIN Relationship rel ON doc.object_id = rel.Head_id
where rel.Head_id IS NULL and doc.is_current=1
group by Doc.creator
order by '# Docs' desc
--list Of Docs
SELECT Doc.creator, doc.create_date, doc.u32_documenttitle , doc.modify_date ,doc.modify_user , ClassDef.symbolic_name as ClassName
FROM DocVersion doc
LEFT JOIN Relationship rel ON doc.object_id = rel.Head_id
INNER JOIN ClassDefinition ClassDef ON doc.object_class_id = ClassDef.[object_id]
where rel.Head_id IS NULL and doc.is_current=1
order by Doc.create_date
