Pl sql invalid datatype error for table casting(PL/SQL: ORA-00902: invalid)

Question

See the code snippet -
Create or Replace Package xyz.abc as
TYPE rec_local is record of (primary_key emp.p_key%type, nam emp.name%type,addres emp.address%type);
Type tab_local is Table of rec_local;
Procedure exclude_pkey (tab1 IN tab_local );
End xyz.abc
Create or Replace Package Body xyz.abc as
Procedure exclude_pkey (tab1 IN tab_local );
Cursor cur is
select primary_key
from table(*cast(tab1 as tab_local *)))
where primary_key NOT IN (select primary_key
from emp)
BEGIN
END exclude_pkey ;
End abc;
I came to know the process that for query purpose we cant use pl/sql type, it must sql type, i.e. creating object and table of that object type in sql,and use of MEMEBER OF ,but what should i do in this case where insted of IN(MEMBER OF can be used for the case of IN) ,NOT IN is used for query.
please reply,
thank you

You are only selecting a single column, primary_key, in your cursor.
You could use the built in sys.ODCINumberlist or sys.ODCIVarchar2list data types instead and pass in only the primary_key.

If you are on an old version you can create your own types with the same definition.
Using a cursor like that I can tell that you want to do whatever this does as slowly and inefficiently as possible though.
