Reserved CQL Keywords and Types (Appendices)
------------------------------------------------

.. _appendix-A:

Appendix A: CQL Keywords
~~~~~~~~~~~~~~~~~~~~~~~~

CQL distinguishes between *reserved* and *non-reserved* keywords.
Reserved keywords cannot be used as an 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 a certain context but can be used as
identifiers otherwise. The only *raison d’être* 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.
