MySQL Parse提示异常

[cnderrick]

在使用Druid的语法解析器时，跑以下代码时：

`
@test

public void getParseModifySqlTask() {
        try {
            MySqlStatementParser parser = new MySqlStatementParser("ALTER TABLE `result` ADD INDEX `index_code` (`code`) USING BTREE;");
            parser.parseStatementList();
        } catch (ParserException e) {
            e.printStackTrace();
        }
}

`

报出如下错误信息：

`

使用了1.1.7 和 1.1.9 都跑了一遍，问题依然存在。分析应该是在SQL解析时出现问题导致的。 删除后面的 USING BTREE，再跑一遍后错误不出现。

该条SQL是可以在MySQL上执行成功的。
