sqlfun
An SQL parser, generated from Bison (Yacc) and Flex (Lex).
Original version - most of the work - comes from John Levine's
Flex & Bison book published by O'Reilley.
Example usage:
$ echo "SELECT a.name,b.address FROM people ORDER BY name;" | ./
这篇文尝试近距离地探究 Druid SQL 解析器如何工作。

public class ParserMain {
public static void main(String[] args) {
