Yes / No field issue

Hi All,

I am facing an issue with "Yes / No Checkbox" field while fetching results from CAML Query.

I have created one sitecolumn with "Yes / No" checkbox type & added the same to a list, now I am using the below code in CAML Designer to fetch the selected checkbox items.

 <Where>
      <Eq>
         <FieldRef Name='Selected' />
         <Value Type='Integer'>1</Value>
      </Eq>
   </Where>

(OR)

   <Where>
      <Eq>
         <FieldRef Name='Selected' />
         <Value Type='Boolean'>True</Value>
      </Eq>
   </Where>

In the both cases I am failing to fetch the selected items.

Can any one of you help me on this issue?

Let me know if you have any queries.

Regards,
SPUser.
