I'm trying to write a CAML query that executes against a specific SPList, scoped to a specific folder, recursive from that point, and returns all ListItems (which meet a criteria) and Folders.
Here's the code for the query which seems like it should work (formatted for readability):
SPQuery query = new SPQuery();
query.Query = "
<Where>
<Or>
<Contains>
<FieldRef Name=\"FileRef\" />
<Value Type=\"Text\">foo</Value>
</Contains>
<Eq>
<FieldRef Name=\"FSObjType\" />
<Value Type=\"Lookup\">1</Value>
</Eq>
</Or>
</Where>";
query.ViewFields = "
<FieldRef Name=\"CustomField1\" Nullable=\"TRUE\" />
<FieldRef Name=\"CustomField2\" Nullable=\"TRUE\" />
<FieldRef Name=\"CustomField3\" Nullable=\"TRUE\" />
";
query.RowLimit = 500;
query.ViewAttributes = "Scope=\"RecursiveAll\"";
query.Folder = startingFolder;
DataTable dt = myList.GetItems(query).GetDataTable();
So - this only returns the ListItems - no folders.
If I remove the other conditions from the query, only leaving the FSObjType=1
, I get a COM exception "Cannot complete this action. Please try again."
If I then remove the ViewFields, leaving only the Scope=RecursiveAll
and FSObjType=1
, I get an empty result set back.
Everyone is close, but not quite right.
using (SPSite site = new SPSite("http://server/site"))
{
SPWeb web = site.RootWeb; // See disposal guidance http://blogs.msdn.com/b/rogerla/archive/2008/10/04/updated-spsite-rootweb-dispose-guidance.aspx
SPQuery query = new SPQuery();
query.Query = @"
<Where>
<BeginsWith>
<FieldRef Name='ContentTypeId' />
<Value Type='ContentTypeId'>0x0120</Value>
</BeginsWith>
</Where>";
query.ViewAttributes = "Scope='RecursiveAll'";
SPList list = web.Lists[listId];
SPListItemCollection items = list.GetItems(query);
// Do stuff with your folders
}
First of all, using this FieldRef is wrong:
<FieldRef Name='ContentType' /><Value Type='Text'>Folder</Value>
because the folder content type can be inherited. Therefore, you need to compare against the content type ID, like this:
<Where>
<BeginsWith>
<FieldRef Name='ContentTypeId' />
<Value Type='ContentTypeId'>0x0120</Value>
</BeginsWith>
</Where>
And then, set the view attribute Scope to RecursiveAll
<View Scope='RecursiveAll'>...</View>
That should return any item whose content type inherits from Folder (0x0120)
