使用日期格式的 Azure 数据工厂动态文件夹名称

Question

I'm having an issue creating the syntax for aa wildcard path expression within my data flow.

We have data coming from a data lake container with a folder structure like the one below with the YYYY/MM/DD being dynamic:

sensor/micActivatedEvent/YYYY/MM/DD/*

I created the below expression but it doesn't seem to be working. I'm trying to load the latest set of files for when the trigger runs the pipeline

@concat(utcNow('yyyy'),'/',utcNow('MM'),'/',utcNow('dd'),'/*')

Yes, you can do this by following the below format,

Use the formatDateTime() on utcnow() with the appropriate format that you need to show year, month and date.

Example sample code:

Case 1:

@concat('sensor/micActivatedEvent/', formatDateTime(utcnow(), 'yyyy/MM/dd'))

Case 2:

Thanks to @Himanshu below is referred from here .

@concat('sensor/micActivatedEvent','/',formatDateTime(utcnow(),'yyyy'),'/',formatDateTime(utcnow(),'MM'),'/',formatDateTime(utcnow(),'dd'))
