Thank you very much for your response, unfortunately this doesn’t work for me - CALL returns an empty result, I call the command through my REST API (it uses this)

Set sql = ##class(%SQL.Statement).%New()

Set sqlStatus = sql.%Prepare("call multi_results()")

Set sqlResult = sql.%Execute()

Congratulations! it was a great competition
