MySQL is considered more &quot;old school&quot; and not great at being standards compliant when installed with default settings.  See <a href="https:&#x2F;&#x2F;twitter.com&#x2F;robconery&#x2F;status&#x2F;189086889486192640" rel="nofollow">https:&#x2F;&#x2F;twitter.com&#x2F;robconery&#x2F;status&#x2F;189086889486192640</a><p>Also, MySQL is run by Oracle...and Oracle a horrible company run by horrible people that behave horribly, and should never ever be trusted in any form.  Any developer relying or Oracle code should not be trusted ever again, and Oracle consultants are the vilest form of life on earth.<p>Did I mention I don&#x27;t like Oracle?
