I have written a query that has a table of Questions with a question_id and a question_description. This links to a table of results where there is a persons client_id, question_id and result_id. I am trying to write a query that averages the result_id per client per question, but displays it per question_description.
My query therefore has client_id, question_description and average(result_id), with the necessary join on question_id.
When i view the query results, in place of the question_description, I get "ȉ" in all cases.
Does anyone know why?
