You have an Azure Synapse Analytics dedicated SQL pool that contains a table named Table1.
You have files that are ingested and loaded into an Azure Data Lake Storage Gen2 container named container1.
You plan to insert data from the files in container1 into Table1 and transform the data. Each row of data in the files will produce one row in the serving layer of
Table1.
You need to ensure that when the source data files are loaded to container1, the DateTime is stored as an additional column in Table1.
Solution: In an Azure Synapse Analytics pipeline, you use a data flow that contains a Derived Column transformation.
Does this meet the goal?

  • A. Yes
  • B. No

Selected Answer: B
Derived Column cannot get DateTime (created or lastmodified datetime) of the files. Get Metadata activity can retrieve the DateTime of the files. so answer should be B.

Cant we just use the current datetime when the data is loaded. It doesnt say that we need to get data from the files. Just datetime which is kind of confusing. I will say, use derived column

If it is a real time process and pipeline is triggered to load data to table1 when file drop to container immediately, the created datetime of the file is similar as the pipeline process datetime. In this way Derived Column works. The question is not clear.

What is the DateTime measuring? The DML transaction time or a file property? If the measurement gives respect to the DML transaction time, you can use this: https://docs.microsoft.com/en-us/azure/data-factory/data-flow-expressions-usage#currentTimestamp
