Question

我想使用Stream Analytics将数据从IoT中心传输到Azure SQL数据库和存储表。我编写输入，输出功能。当一台Iot设备使用流分析作业与azure iot-hub连接并将数据存储在sql表中，但是当我们连接多台Iot设备与Azure Iot-Hub连接时。

我们面临两个问题：

一段时间后，一台物联网设备与azure iot-hub断开连接，直到重新启动脚本或设备后才重新连接
在Stream Analytics作业活动日志中显示发送事件错误表示具有特定输出的数据转换。

我的查询是：

SELECT 
    CompanyProfileId, JunctionListId, MonitoringString, area_id
INTO
    MonitoringOutput
FROM
    MonitoringInput
WHERE
    MonitoringString IS NOT NULL
    AND CompanyProfileId IS NOT NULL

SELECT 
    JunctionListId, F1_Sec, F2_Sec, F3_Sec, F4_Sec, F5_Sec, 
    F6_Sec, F7_Sec, F8_Sec, F9_Sec, F10_Sec, DateAdded
INTO
    GreenTimeOutput
FROM
    GreenTimeInput
WHERE
    JunctionListId IS NOT NULL 
    AND F1_Sec IS NOT NULL
    AND F2_Sec IS NOT NULL
    AND DateAdded IS NOT NULL

SELECT   
    JunctionListId, F1_Vehicle, F2_Vehicle, F3_Vehicle, F4_Vehicle,
    F5_Vehicle, F6_Vehicle, F7_Vehicle, F8_Vehicle, F9_Vehicle,
    F10_Vehicle, DateAdded
INTO
    VehicleCountOutput
FROM
    VehicleCountInput
WHERE
    JunctionListId IS NOT NULL
    AND F1_Vehicle IS NOT NULL
    AND F2_Vehicle IS NOT NULL
    AND DateAdded IS NOT NULL

请给我任何解决方案，我需要做什么？
