Sets or returns a ParameterDirectionEnum value that defines the type of the Parameterobject (input, output, input/output and return).
The Direction property is used to set or return a ParameterDirectionEnum constant
that defines the direction of a Parameter object.
By direction, we refer to how a Parameter is passed to or from a provider.
This can be an input, output, input/output, or a returned value from a stored procedure.
You can also set the direction by using the CreateParameter method of the
Command object.
The default direction for this method is adParamInput.
