I am using ADF Dataflow dervied column expression toInteger(toString(RowId)). This expression is producing Null values.

Hi @Sarvesh Pandey ,

Thankyou for using Microsoft Q&A platform and thanks for posting your question here.

In order to convert the datatype , you can use Cast transformation in mapping data flow. The Cast transformation enables super-easy data type conversions with built-in type checking. Use the column drop-down to select columns from your stream of metadata for type conversion.

For more details, kindly check : Cast Transformation in Mapping data flows in Azure Data Factory or Azure Synapse Analytics

Hope this will help. Please let us know if any further queries.
