Kræver Oracles PS/SQL specifik rækkefølge af poster i "erklære"-sektionen af ​​en blok

Fra Oracle 10g R2 er svaret ja, der er en påkrævet rækkefølge mellem elementer i item_list_1 og item_list_2, selv hvis markørdefinitioner er tilladt at være forkerte.

For eksempel er en proceduredefinition ikke tilladt før en variabelerklæring:

SQL> select * from v$version;
