 执行请求：
 
 ```shell

 http://127.0.0.1:8361/api/v1/sql?db=demo \
 -H 'Content-Type: application/binary' \

 返回值：

-      "message"

 ```
 
 其中，`result`表示这是一条查询的结果,`columns` 为列名，`types` 为列类型，`values` 为查询到的行数组。需要注意的是，类型中时间戳的表示为`Timestamp(TimeUnit, Timezone)`，当某列类型是时区未被指定的时间戳时，Timezone为None。例如`Timestamp(Millisecond, None)`。
