Calling ADX function in Source Copy ADF activity

Established Member

Hi,

I'm new in kusto. I'm trying to execute Data explorer function in ADF in source Copy level activity with input parameter that should be taken from pipeline variable/parameter. Result will be written in Data Lake.

Q: Is it possible to be called Data explorer function from ADF Source Copy activity , and what should be the syntax in Query filed in ADF?

I'm trying first to execute function with fixed input parameter but it is not working. 

let StringParam = '1234'

functionName(StringParam );

 

What should I have in ADF Query ,if i want to use pipeline parameter/variable as input parameter in ADF Copy activity ?

let StringParam = @variables('VariableName');
functionName(StringParam );

 

Thanks,
