/*
* Merged in all changes up to mysql-trunk git revision [6d4f66a] (16. January 2020).
*
* MySQL grammar for ANTLR 4.5+ with language features from MySQL 5.6.0 up to MySQL 8.0.
* The server version in the generated parser can be switched at runtime, making it so possible
* to switch the supported feature set dynamically.
*
* The coverage of the MySQL language should be 100%, but there might still be bugs or omissions.
*
* To use this grammar you will need a few support classes (which should be close to where you found this grammar).
* These classes implement the target specific action code, so we don't clutter the grammar with that
* and make it simpler to adjust it for other targets. See the demo/test project for further details.
*
* Written by Mike Lischke. Direct all bug reports, omissions etc. to mike.lischke@oracle.com.

The syntax for defining an index is:

The problem is that whereas USING is a reserved word, TYPE is not. We can
still handle it if an index name is supplied, i.e.:
... INDEX type TYPE <index_type> ...
here the index's name is unmbiguously 'type', but for this:
... INDEX TYPE <index_type> ...
it's impossible to know what this actually mean - is 'type' the name or the
type? For this reason we accept the TYPE syntax only if a name is supplied.

From the server grammar:
MySQL has a syntax extension that allows into clauses in any one of two
places. They may appear either before the from clause or at the end. All in
a top-level select statement. This extends the standard syntax in two
ways. First, we don't have the restriction that the result can contain only
