在Node.JS Web应用程序中使用mongoDB(Using mongoDB in Node.JS web application)

 使用SPList.Items不会返回所有项目？ 好吧，然后尝试SPList.GetItems（SPQuery） 。 
 
 有一个以下的SPQuery： 
 
SPQuery query = new SPQuery();
query.ViewFields = "<FieldRef Name='ID'/><FieldRef Name='Title'/>";
query.Query = String.Format("<Where><Eq><FieldRef Name='Title'/><Value Type='Text'>{0}</Value></Eq></Where>", someItemTitle)
query.MeetingInstanceId = -1; //In case if you query recurring meeting workspace - get items from all meetings
query.RowLimit = 10; //Will you have more than 10 duplicates? Increase this value
query.ViewAttributes = "Scope='RecursiveAll'"; //Also return items from folders subfolders
 
 注意：代码中可能存在一些错误，因为我是从头脑中写的 
 
 通过执行此查询，如果它返回多个项目，那么您有一个副本！ 
 
 编辑：啊，对不起，你在谈论Web服务。 
 
 然后这段代码无济于事。 那么有两个选择： 
 
 选项1：您可以创建一个甚至可以从文件夹中包含项目的视图（平面视图）。 请参阅此处获取说明 
 
 选项2：根据列表Web服务的GetListItems方法，您可以传递QueryOptions参数。 通过 
 
<QueryOptions>
   <MeetingInstanceID>-1</MeetingInstanceID> <!-- Again, if you query recurring meeting, you want ALL items -->
   <ViewAttributes Scope='RecursiveAll' /> <!-- or Recursive if that does not work -->
</QueryOptions>
 
 祝你好运！ 

Use SPList.Items doesn't return all items? Well, then try SPList.GetItems(SPQuery).
 
Have a following SPQuery:
 
SPQuery query = new SPQuery();
query.ViewFields = "<FieldRef Name='ID'/><FieldRef Name='Title'/>";
query.Query = String.Format("<Where><Eq><FieldRef Name='Title'/><Value Type='Text'>{0}</Value></Eq></Where>", someItemTitle)
query.MeetingInstanceId = -1; //In case if you query recurring meeting workspace - get items from all meetings
query.RowLimit = 10; //Will you have more than 10 duplicates? Increase this value
query.ViewAttributes = "Scope='RecursiveAll'"; //Also return items from folders subfolders
 
Note: There could be some mistakes in code, because i`m writing from top of my head
 
By executing this query and if it returns more than one item, then you have a duplicate!
 
Edit: Ahh, sorry, you are talking about Web Services.
 
Then this code won't help. There are 2 options then:
 
Option 1: You CAN create a view that does include items even from folders (flat view). See here for instructions.
 
Option 2: According to Lists Web Service's GetListItems method, you can pass QueryOptions parameter. Pass in 
 
<QueryOptions>
   <MeetingInstanceID>-1</MeetingInstanceID> <!-- Again, if you query recurring meeting, you want ALL items -->
   <ViewAttributes Scope='RecursiveAll' /> <!-- or Recursive if that does not work -->
</QueryOptions>
 
Good luck!
