What syntax references Pipeline parameters in the where clause of a SQL query of 'Import Data' modules in Microsoft Azure Machine Learning designer?

Question

I have created a pipeline in Microsoft Azure Machine Learning designer. I have added a Pipeline parameter myNumber in the pipeline settings, with a valid default value, to accept the unique ID of the asset in our DB so that the pipeline can return only the asset-specific data for use as our model input. Specifically I want to reference that pipeline parameter in the where clause of the SQL query in the 'Import Data' module that connects to our Azure SQL server.

I cannot find a reference in the documentation on how to do this. I have tried the methods specified for accomplishing this task in Azure Data Factory, using where RowId = @pipeline().parameters.myNumber or where RowId = @{variables('myNumber')} but the experiment fails with SqlException error code '137', variable not defined.

Can you please tell me the necessary syntax to reference Pipeline parameters in the where clause of a SQL query of 'Import Data' modules of Microsoft Azure Machine Learning designer?
