SharePoint - Doing a user lookup on GetListItems SOAP call

Question

I'm using jQuery and the WSS 3.0 SOAP service to retrieve and display data from a list. I'm wanting to filter the data by the CreatedBy column. Here's my CAML query:

<Query>
<Where>
    <And>
        <Leq>
            <FieldRef Name="Created" />
            <Value Type="DateTime" IncludeTimeValue="FALSE">2011-1-8</Value>
        </Leq>
        <Geq>
            <FieldRef Name="Created" />
            <Value Type="DateTime" IncludeTimeValue="FALSE">2011-1-2</Value>
        </Geq>
        <Contains>
            <FieldRef Name="CreatedBy" LookupId="TRUE" />
            <Value Type="User">Smith</Value>
        </Contains>
    </And>
</Where>

When I execute this, SharePoint returns the following error:

0x80004005 - Cannot complete this action. Please try again.

Removing the user lookup resolves the issuer. Where am I going wrong?

Answer 1

If you want to use their display name, then you cannot use LookupId="TRUE" or a Type="User" . It should be:

<Contains>
   <FieldRef Name="CreatedBy" />
   <Value Type="Text">Smith</Value>
</Contains>

See my answer here for more examples.

Edit:

Also, I just noticed your <And></And> node contains three sub-nodes. Each one can only contain two, which means you need something like this:

<Where>
  <And>
    <And>
      <Leq>
        <FieldRef Name="Created" />
        <Value Type="DateTime" IncludeTimeValue="FALSE">2011-1-8</Value>
      </Leq>
      <Geq>
        <FieldRef Name="Created" />
        <Value Type="DateTime" IncludeTimeValue="FALSE">2011-1-2</Value>
      </Geq>
    </And>
    <Contains>
      <FieldRef Name="CreatedBy" />
      <Value Type="Text">Smith</Value>
    </Contains>
  </And>
</Where>
