PLS-00586

Error: PLS-00586: a static method cannot declare a parameter named SELF

Causa: An attempt was made to name a parameter SELF when declaring a static method. SELF is reserved as a parameter name in methods, to hold the object instance on which the method is applied. A parameter named SELF is not allowed in static methods because static methods do not apply to a particular object instance.

Acción: Change the name of the parameter in the declaration.
