问题描述
我正在尝试学习Azure IoT.我正在尝试将MQTT消息发送到IoT中心.从物联网中心，我正在使用流分析将数据输出到SQL数据库.但是目前在Streaming Analytics输出中，我遇到此错误:
I am trying to learn Azure IoT. What i am trying to is to send MQTT message to IoT Hub. And from IoT hub, i am using Streaming Analytics to output the data into SQL Database. But currently in Streaming Analytics Output, i have this error:
这是我要保存的数据
我认为错误在于IoTHub部分.
I think the error is in IoTHub part.
这是我要保存的Azure Sql Server中的表:
This is the table in Azure Sql Server that i am trying to save:
CREATE TABLE [dbo].[IoTMQTT](
[EventID] [bigint] IDENTITY(1,1) NOT NULL,
[ActionBy] [nvarchar](400) NOT NULL,
[ActionDate] [datetime] NOT NULL,
[Topic] [nvarchar](400) NULL,
[Message] [nvarchar](400) NULL,
[QoS] [nvarchar](400) NULL,
[EventProcessedUtcTime] [datetime] NULL,
[PartitionId] [nvarchar](400) NULL,
[EventEnqueuedUtcTime] [datetime] NULL,
[IoTHub] [nvarchar](max) NULL,
)
出什么问题了?是数据类型吗?请帮我.谢谢！
What is the problem? Is it the datatype? Please help me. Thank you!
推荐答案
Azrue SQL数据库可以将"2019-05-23T00:19:31.8287610Z"转换为datetime2，smalldatetime，time，date ，但datetime除外.这是错误消息:
Azrue SQL Database can convert "2019-05-23T00:19:31.8287610Z" to datetime2 , smalldatetime, time, date, except datetime. Here is the error massage:
根据您的数据，我认为数据类型datetime2最适合您.
According your data , I think the datatype datetime2 best for you.
请修改表格，将ActionDate，EventProcessedUtcTime，EventEnqueuedUtcTime列更改为datetime2.
Please modify your table, alter ActionDate, EventProcessedUtcTime, EventEnqueuedUtcTime columns to datetime2.
希望这会有所帮助.
