jOOQ's code generator internamente utiliza la siguiente consulta para encontrar de forma fiable todos los nivel de paquete PL/SQL RECORD
tipos:

En su caso, el resultado será algo como:

TEST_PACKAGE PERSON_RECORD_TYPE FIRST_NAME VARCHAR2 1000
TEST_PACKAGE PERSON_RECORD_TYPE LAST_NAME VARCHAR2 1000
limitaciones actuales:
- La consulta solo encontrará los tipos que son re Ferenced por al menos otro tipo y/o procedimiento en alguna parte. Esta es una limitación heredada de la vista del diccionario
ALL_ARGUMENTS
en la consulta.
%ROWTYPE
tipos no se devuelven correctamente porque el tipo de fila no se hace referencia a partir de las columnas TYPE_NAME
/TYPE_SUBNAME
.

obtener los campos desde dentro del mismo paquete? – tbone
@tbone: No necesariamente. Me gustaría obtener los campos de un paquete diferente. –
"obtenerlos", que significa usarlos ¿cómo? ¿Puedes dar algún pseudo código de lo que estás tratando de lograr en este otro paquete? – tbone
