PLS-00309

Error: PLS-00309: with \%LAST attribute, 'string' must be a variable of an enumerated type

Causa: The "\%LAST" attribute must be applied to an identifier that has been declared as a variable of an enumerated type (or subtype of an enumerated type). This error occurs when "\%LAST" follows some identifier that has not been so declared.

Acción: Make sure that \%LAST follows an enumerated type (or subtype of an enumerated type).
