Sample streaming table is failed

[shsalami]

• Running the following databricks sample code in the pipeline:

CREATE OR REFRESH STREAMING TABLE customers

AS SELECT * FROM cloud_files("/databricks-datasets/retail-org/customers/", "csv")

• I got error:

org.apache.spark.sql.catalyst.ExtendedAnalysisException: Unable to process statement for Table 'customers'.

com.databricks.sql.cloudfiles.errors.CloudFilesIllegalArgumentException: Reading from a Delta table is not supported with this syntax. If you would like to consume data from Delta, please refer to the docs: read a Delta table (https://docs.microsoft.com/azure/databricks/delta/tutorial#read), or read a Delta table as a stream source (https://docs.microsoft.com/azure/databricks/structured-streaming/delta-lake#table-streaming-reads-an...). The streaming source from Delta is already optimized for incremental consumption of data.

Hi @shsalami ,

The error you're encountering suggests you are attempting to read a Delta table as if it were a collection of CSV files using the cloud_files function.
You may run "DESCRIBE DETAIL customers" and check whether this table exists and it is located in "/databricks-datasets/retail-org/customers/". The other way is to navigate to this location in your cloud storage. It may happen that you already created a Delta table in that location before. The syntax for reading from delta table is different.
