Example

The following example conveys criteria for a query on the ProductID field: (ProductID = J1539 AND ProductID = J9862) AND (ProductID = J0394 OR ProductID = J4589).

<And>
  <And>
    <Eq>
      <FieldRef Name="ProductID"/>
      <Value Type="Text">J1539</Value>
    </Eq>
    <Eq>
      <FieldRef Name="ProductID"/>
      <Value Type="Text">J9862</Value>
    </Eq>
  </And>
  <Or>
    <Eq>
      <FieldRef Name="ProductID"/>
      <Value Type="Text">J0394</Value>
    </Eq>
    <Eq>
      <FieldRef Name="ProductID"/>
      <Value Type="Text">J4589</Value>
    </Eq>
  </Or>
</And>

The following example performs a query for cases in which values of the Status field do not equal Completed and values of the Sent field are null. The records returned are sorted in descending order according to values of the Modified field.

<Query>
  <OrderBy>
    <FieldRef Name="Modified" Ascending="FALSE"></FieldRef>
  </OrderBy>
  <Where>
    <And>
      <Neq>
        <FieldRef Name="Status"></FieldRef>
        <Value Type="Text">Completed</Value>
      </Neq>
      <IsNull>
        <FieldRef Name="Sent"></FieldRef>
      </IsNull>
    </And>
  </Where>
</Query>
