title: Does Oracle have an equivalent of SQL Server's table variables?
body: <p>In SQL Server, you can declare a table variable (<code>DECLARE @table TABLE</code>), which is produced while the script is run and then removed from memory.</p>
  
  <p>Does Oracle have a similar function? Or am I stuck with <code>CREATE</code>/<code>DROP</code> statements that segment my hard drive?</p>
