hi folks,

I am very happy about the new enum domains in PL/SQL. They are very useful and can make the code much more maintainable.
But I struggled over a problem. When I create an enum domain like

create domain MY_TEST_ENUM as enum (
  text1 = 'text1',
  text2 = 'text2',
  text3 = 'text3'    
)

and I would like to use it in e.g. a procedure like this

create procedure superDuper is
  lTestString varchar2(100);
begin
  select MY_TEST_ENUM.text1 into lTestString from dual; -- first try
  lTestString := domain_display(MY_TEST_ENUM.text2);    -- second try
  lTestString := MY_TEST_ENUM.text3;                    -- third try
end;
/

the compiler feels well and accepts my code in the the first try.
But for the second try which is some sort of easier to read and understand it shouts out a "PLS-00201: identifier 'DOMAIN_DISPLAY' must be declared".
For the third try which is the best readable way it gives me a "PLS-00905: object 'MY_TEST_ENUM' is invalid". Btw the object is not invalid when asking the ALL_OBJECT table.
Is there a way to assign the value of an enum domain without using a select statement?

Cheers
Knut

create procedure superDuper is
  lTestString varchar2(100);
begin
  select MY_TEST_ENUM.text1 into lTestString;
end;

drop domain MY_TEST_ENUM ;
create domain MY_TEST_ENUM as enum (
  name1 = 'val1',
  name2 = 'val2',
  name3 = 'val3'    
)
/

select 
  MY_TEST_ENUM.name1,
  domain_display ( cast ( MY_TEST_ENUM.name1 as MY_TEST_ENUM ) );
