I currently have the below query that uses a UNION join to connect two queries and SQL variables to alternate the order the rows are shown between sum of numbers and count of activities. When I add the SET lines to the query the PHP file has an error and when I remove them the query runs but no values are retrieved. I've run the query on the server and it works.
How do I use SQL variables in the prepared statement? If it's not possible how would I rewrite the query to get the same outcome?
