If you are calling the procedure from within another stored procedure or function, you can also pass a routine parameter or local routine variable as an IN or INOUT parameter. The DatabaseConnector.Parameter type uses the Name and Position attributes to refer to either the parameter name or position in the stored procedure. If your stored procedure does not return any output, but just performs an operation on the backend of your database, like writing to a log table, then you’ll use the stored procedure.
