title: Is SQL syntax case sensitive?
body: <p>Is SQL case sensitive?  I've used <a href="https://en.wikipedia.org/wiki/MySQL" rel="nofollow noreferrer">MySQL</a> and <a href="https://en.wikipedia.org/wiki/Microsoft_SQL_Server" rel="nofollow noreferrer">SQL Server</a> which both seem to be case insensitive.  Is this always the case?  Does the standard define case-sensitivity?</p>
