Clickhouse SQL Parser

This is a Go Clickhouse SQL Parser built with Antlr4.

The original antlr4 grammar files are from the official clickhouse repository, although the maintainers of clickhouse have stated that this is unsupported, but this is still the easiest way to quickly build a clickhouse sql parser with as robust as possible.

The original antlr4 grammar files contain a little bit of C++ code, but this can be replaced with Go easily, you can see the current grammar file here.
