Reading the documentation regarding Parameterized queries on AF Tables Lookup, I'm a little confused with one of the examples. The third example (refer to image below) shows the usage of an expression of @id=@AssetId. I have tried to follow that approach with the impression that I can assign the column name as a variable but I haven't had a result from the queries. Is the assumption is correct? Could be possible to explain a little more providing additional example how to use that approach of parameterization?
Thanks in advance!
