I dont think its a network issue. If I get rid of the formalParemter and use straight SQL it works fine. At the bottom of the post you can see the error 'must decalare parameter giftyear;' .
This question is really about how to use formal parameters in a SQL Query

I can confirm that if you have the DECLARE section for each variable in 'formalParameters' then the query works as expected.
It'd be good if it was made apparent in the UI or in the error message that this DECLARE is required, as I assumed formal parameters were simply broken until I read this post.
It's not easy to find the documentation for Execute a SQL Query either - maybe this does mention this requirement. Could you point us to it?
EDIT: Actually it is not working. There is no error given but the SQL doesn't actually produce the result I'm expecting.
Is there any documentation for formalParameters? I'm very much at a loss as how to use the feature at all.
can you elaborate on what exactly is not working? Is the SQL query returning unexpected results, no results at all or do you have issues accessing / processing the resultset later in PowerApps etc. ?
Thanks and best regards
I can also confirm that adding the variable declaration fixed the syntax issue and allowed the step to process succcessfully. However, I also got unexpected results in that the dataset came back empty (and should have returned 1 row based on the parameter)
Turing on auditing on my SQL instance showed 2 interesting events:
I agree that this function is poorly documented, which makes it difficult to understand if we're even using it correctly. In fact, the current specification here (https://docs.microsoft.com/en-us/connectors/sql/#execute-a-sql-query-(v2)) doesn't even mention formalParameters as a valid parameter.
