mysqlparser

this is a mysql parser, lexer is modified from mysql5.6.35 source code to java by myself, parser is created by bison2.7. 一个mysql的sql解析，词法解析部分是人工将mysql5.6.35源码翻译成java版，语法解析部分是通过bison2.7对mysql5.6.35中sql_yacc.yy文件生成的，语义解释部分由于sql_yacc.yy中都是c语言的，所以生成的语义解释都注释掉了，导致解析以外的所有功能需要用java重新改造，目前只实现了获取sql类型，库名，表名，有时间的话可能会再追加wherelist。。。。。

Sample

	try {
		MySQLParser parser = new MySQLParser();
		List<ParseResult> resultList = parser.parse("select * from acdb.acc where id = 1;delete from acdb.acc;insert into acdb.acc select * from acdb.acc where id = 1;");
		for(ParseResult result : resultList) {
			System.out.println("==================================");
			System.out.println(result.getParsedSQL());
			System.out.println(result.isSuccess());
			if (result.isSuccess()) {
				System.out.println(result.getSqlCommand());
				System.out.println("inWhere: " + result.inWhere());
				for (AlterFlag af : result.getAlterFlags()) {
					System.out.println(af);
				}
				for (TableIdent ident : result.getTables()) {
					System.out.println(ident.getDb() + "." + ident.getTable());
				}
			} else {
				System.out.println(result.getErrorMsg());
			}
		}
	} catch (IOException e) {
		e.printStackTrace();
	}
