title: Convert SQL Data in columns into an array
body: <p>Imagine you have a simple table</p>
  <pre><code>  Key c1 c2 c3
  A id1  x  y  z
  B id2  q  r  s
  </code></pre>
  <p>what I would like is a query that gives me the result as 2 arrays
  so something like</p>
  <pre><code>Select
  id1,
  ARRAY_MAGIC_CREATOR(c1, c2, c3)
  from Table
  </code></pre>
  <p>With the result being</p>
  <pre><code>id1, &lt;x,y,z&gt;
  id2, &lt;q,r,s&gt;
  </code></pre>
  <p>Almost everything I have searched for end up converting rows to arrays or other similar sounding but very different requests.</p>
  <p>Does something like this even exist in SQL?
  Please note that the data type is NOT a string so we can't use string concat.  They are all going to be treated as floats.</p>
