<span id="appendix-a"></span><h2>Appendix A: CQL Keywords<a class="headerlink" href="#appendix-a-cql-keywords" title="Permalink to this headline"></a></h2>
<p>CQL distinguishes between <em>reserved</em> and <em>non-reserved</em> keywords.
Reserved keywords cannot be used as identifier, they are truly reserved
for the language (but one can enclose a reserved keyword by
double-quotes to use it as an identifier). Non-reserved keywords however
only have a specific meaning in certain context but can used as
identifier otherwise. The only <em>raison d’être</em> of these non-reserved
keywords is convenience: some keyword are non-reserved when it was
always easy for the parser to decide whether they were used as keywords
or not.</p>
