InfluxDB上的“未执行”错误是什么？

Question

当我一次发送5个查询时，influxdb有时会返回错误，如下所示。

查询

"SELECT max(\"price\") as high FROM \"trades\" WHERE \"market\" = 'AAA' AND time >= 1538902355s AND time < 1538902385s;
SELECT max(\"price\") as high FROM \"trades\" WHERE \"market\" = 'AAA' AND time >= 1538902325s AND time < 1538902385s;
SELECT max(\"price\") as high FROM \"trades\" WHERE \"market\" = 'AAA' AND time >= 1538902025s AND time < 1538902385s;
SELECT max(\"price\") as high FROM \"trades\" WHERE \"market\" = 'AAA' AND time >= 1538901665s AND time < 1538902385s;
SELECT max(\"price\") as high FROM \"trades\" WHERE \"market\" = 'AAA' AND time >= 1538900945s AND time < 1538902385s"

响应

[{"statement_id": 0}, {"error": "not executed", "statement_id": 1}]

“未执行”是什么意思？我在任何文档上都找不到。
