Set the output of Azure stream analytics to be Event Hub

Question

I am trying to use the event hub as the output sink for the Azure stream analytics and the code to do it is shown below.

  OutputCreateOrUpdateParameters jobOutputCreateParameters = new OutputCreateOrUpdateParameters()
        {
            Output = new Output()
            {
                Name = streamAnalyticsOutputName,
                Properties = new OutputProperties()
                {
                    Serialization = new JsonSerialization
                    {
                        Properties = new JsonSerializationProperties
                        {
                            Encoding = "UTF8"
                        }
                    },

                    DataSource = new EventHubOutputDataSource
                    {
                        Properties = new EventHubOutputDataSourceProperties

                        {
                            ServiceBusNamespace = "UKFC2-ns",
                            SharedAccessPolicyName = "manage",
                            SharedAccessPolicyKey = "aWFOgfkXPCYz5fdLMIIPXGEkT0EszW+g/OEOI3jhx5U=",
                            EventHubName = "ukfc1",
                            PartitionKey = partition
                        }
                    }
  }

What I want to do is to send the result of the stream analytics to a specific partition in the event hub. I did it by setting the PartitionKey property to a string I defined. However, that doesn't work. It seems that the partitionKey property in the EventHubOutputDataSourceProperties is not the partition key used in the event hub. Then my question is how can I send the to a specific partition and set the partition key to what I want.

Any help is appreciated.

PartitionKey属性需要查询输出中的列。要解决此问题，请在查询中添加一个代表所需分区的列。如果您的输入没有您想要的EH分区，您可以将其硬编码到查询中：

SELECT '1' AS EHPartition, Column1, ... into output from input

然后将PartitionKey属性设置为＆＃34; EHPartition＆＃34;。
