title: Are table names in query case-insensitive?
body: <p>I have read the following <a href="http://support.microsoft.com/kb/113317" rel="noreferrer">article</a>. They have quoted that,</p>
  
  <blockquote>
    <p>SQL Server is a case-sensitive back-end application. This means that a
    table named "addr" is distinguished from a table named "ADDR."
    However, because Microsoft Query is an MS-DOS-based application, it is
    unable to distinguish cases; therefore, Microsoft Query views "addr"
    and "ADDR" as the same file.</p>
  </blockquote>
  
  <p>Now I wanted to know what to they mean by <code>case-sensitive back-end application</code>? Is it safe to use the <code>query</code> with <code>case-insensitivity</code>?</p>
  
  <p>Thanks in advance.</p>
