Kindly write the query that you usually use to execute a procedure in your database (not with buttons in you db tool, need a query to run a procedure) like how we have insql server
EXEC proc_name 'paramValue1','paramValue2'
We have an activity called execute query where we can mention the query as string input
The output variable of that execute query activity will of type datatable, with which you can enter to any table excel or even to another table with insert query activity,
The thing you will be in need is the servername, usename and password
