ORA-21700: object does not exist or is marked for delete for Associative Array as input parameter called from ODP.NET

Question

I have this package code on Oracle 12c

CREATE OR REPLACE PACKAGE Support_Data_Types AS
  TYPE ttDate            IS TABLE OF DATE  
END Support_Data_Types;

Answer 1

after several days of googling, I changed the code this way:

CREATE OR REPLACE PACKAGE Support_Data_Types AS
            TYPE ttDate            IS TABLE OF DATE
END Support_Data_Types;
PROCEDURE GetData
(
    tabDates IN SUPPORT_DATA_TYPES.TTDATE,
)
AS
    v_temp SUPPORT_DATA_TYPES.TTDATE:= tabDates;  -- assigned the parameter to a temporary variable
BEGIN
    SELECT count(*) INTO n FROM table(v_temp);
END GetData;

the only thing I did is to use a v_temp which looks quite redundant. but it works. I made this change because I searched this article here ... it mentioned:

Note, however, that as of 12.1, you cannot call the table function directly inside the TABLE operator. You must invoke it in PL/SQL, assign result to a variable, and then reference the variable inside TABLE.

though the situation is different in my case (I m using 12.2), it solved my problem.
