Question JSON parameter for an SQLtoPArameter

Hello everyone,
I'm making a Process in order to be use as a Web Service. The idea is that the client send a JSON file as an input (as you can see in img1.png on the red square), after that i want to execute an SQLtoParameter component with a query (see img2.png) in order to return a row from the table. The problem is that, aparantly the query is not reonasign or there is asintaxys mistake in orden to invoke the paramater.

I hope somebody can help me.

Hello, the syntax used in img2.png to get the Json content does not exist in Stambia.
What you need to do is loading the json content to a temporary table, so that you can join it with the data table.
Loading the json content to a temporary table can be done with a standard mapping Json => Rdbms.
