| 查询:
<Where>
  <Eq>
    <FieldRef Name=\'Document Type\' LookupId=\'True\' />            
    <Value Type=\'Text\'>Standards(STA)</Value>
  </Eq>
</Where>
<OrderBy>
 <FieldRef Name=\'Number\' Ascending=\'False\'/>
</OrderBy>
<RowLimit>1</RowLimit>\"

        我认为问题是字段引用\“ Document Type \”: “ 3”元素需要引用字段的内部名称。如果列“文档类型”是通过UI创建的,则此列的内部名称为“ Document_x0020_Type \”。 您指定了“ 4”,这会导致对查找字段的ID进行查找,但是您提供了一个文本值。根据您的字段类型,您应该提供文档类型的数字ID或省略“ 4”部分以查询查找字段的文本。
