Should this CAML be working. (I tried it with u2u and it does not display the URL column.) I get this error. {System.ApplicationException} = {"One or more field types are not installed properly. Go to the list settings page to delete these fields."}
<Where>
<Eq>
<FieldRef Name='URL' />
<Value Type='URL'>/path/HR Policy.docx</Value>
</Eq>
</Where>
Querying for a Document in a Document Library
Looks like you are trying to find a document in a document library using CAML. You can do this by using the hidden column named "FileRef":
<Where><Eq><FieldRef Name="FileRef"/><Value Type="Url">sites/SiteCollection/SubSite/Site Documents/Excel Report.xls</Value></Eq></Where>
Note: Do not include the server name or beginning /
.
Querying for a document or list item with a URL field
The following examples assuming you have a list or library setup with a URL column named "My Document".
The link is to a document that is hosted on the sharepoint server (do not need server name):
<Where><Eq><FieldRef Name="My_x0020_Document"/><Value Type="URL">/sites/subsite/Site%20Documents/Excel%20Report.xls</Value></Eq></Where>
The link is an absolute URL to something not on the server... for example http://www.google.com
:
<Where><Eq><FieldRef Name="My_x0020_Document"/><Value Type="URL">http://www.google.com</Value></Eq></Where>
