Question

with a as (
      select a.PrimaryKey,
             max(case when seqnum = 1 then score end) as score,
             max(case when seqnum = 2 then score end) as score_previous
      from (select a.*,
                   row_number() over (partition by PrimaryKey order by DateField desc) as seqnum
            from TableA a
           ) a
      where seqnum <= 2  -- This should help performance of the `group by`
      group by a.PrimaryKey
     )
select b.*, a.score, a.score_previous
from b join
     a
     on b.primarykey = a.primarykey;

你想要像htis这样的东西： -

.dropbtn {
    background-image:url(download.jpg);

    color: white;
    padding: 16px;
    font-size: 16px;
    border: none;
    cursor: pointer;
}

.dropdown {
    position: relative;
    display: inline-block;
}

.dropdown-content {
    display: none;
    position: absolute;
    background-color:#FFF;
    min-width: 160px;
    box-shadow: 0px 8px 16px 0px rgba(0,0,0,0.2);
}

.dropdown-content a {
    color: black;
    padding: 12px 16px;
    text-decoration: none;
    display: block;
}

.dropdown-content a:hover {background-color: #f1f1f1}

.dropdown:hover .dropdown-content {
    display: block;
}

.dropdown:hover .dropbtn {
    background-color: #3e8e41;
}

<div class="dropdown">
  <button class="dropbtn">PROIZVODI</button>
  <div class="dropdown-content">
   <li><a href="reciklazaplastike.html">RECIKLAŽA</a></li>
                    <li><a href="oprema.html">OPREMA</a></li>
                    <li><a href="onama.html">O NAMA</a></li>
                    <li><a href="contactform.php">KONTAKT</a></li>
            </ul>
            <a href="#" id="pull">Meni</a>
        </nav>
  </div>

试试这个asap版本一：

ul#drop {
  display: none;
  trasition: 3s all linear;
}

[data-toggle=drop]:hover {
 color: red;
}

[data-toggle=drop]:hover > ul#drop {
 display:block;
}

<ul id="drop1">
<li><a href="#">menu 1</a></li>
<li data-toggle="drop"><a href="#">menu 2 (hover here)</a>
  <ul id="drop">
  <li><a href="#">sub-menu 1</a></li>
  <li><a href="#">sub-menu 2</a></li>
  </ul>
</li>
<li><a href="#">menu 3</a></li>
</ul>
