How to pass the ObjectType as input for search Criteria

Question

Hi All,
I have search function that takes the input parameters and returns all the matching rows. this is straight forward only. My problem is having multiple types as a input parameter. that is the reason i am not able to pass the input value for these types.
My Input Type table looks like this.
CREATE OR REPLACE TYPE T_T_PARTY_REQUEST_CRITERIA
AS TABLE OF T_O_PARTY_REQUEST_CRITERIA;
CREATE OR REPLACE TYPE T_O_PARTY_REQUEST_CRITERIA
AS OBJECT
SYSTEM_IDENTIFER VARCHAR2(50),
PROCESS_TYPE VARCHAR2(50),
UPDATED_BY VARCHAR2(50),
STATUS VARCHAR2(50),
CHILD_REQUEST_INDICATOR VARCHAR2(25),
TRACKING_REQUEST_INDICATOR VARCHAR2(25),
REQUEST_TYPE VARCHAR2(50),
REQUEST_TYPE_CLASS_NAME VARCHAR2(50),
PARTY_KEY_IDENTIFIER T_T_PARTY_KEY_IDENTIFIER,
ADDTN_IDENTIFIER_INFO T_T_ADDTN_IDENTIFIER_INFO
Last two inputs are type again.my question here is how to pass the values for these two T_T_PARTY_KEY_IDENTIFIER and T_T_ADDTN_IDENTIFIER_INFO. I have defined the the last two types following.
CREATE OR REPLACE TYPE T_T_PARTY_KEY_IDENTIFIER
AS TABLE OF T_O_PARTY_KEY_IDENTIFIER;
CREATE OR REPLACE TYPE T_T_ADDTN_IDENTIFIER_INFO
AS TABLE OF T_O_ADDTN_IDENTIFIER_INFO;
CREATE OR REPLACE TYPE T_T_ADDTN_IDENTIFIER_VALUES
AS TABLE OF T_O_ADDTN_IDENTIFIER_VALUES;
CREATE OR REPLACE TYPE T_O_PARTY_KEY_IDENTIFIER
AS OBJECT
PARTY_KEY_TYP_NM VARCHAR2(50),
PARTY_KEY_VALUE VARCHAR2(50)
CREATE OR REPLACE TYPE T_O_ADDTN_IDENTIFIER_INFO
AS OBJECT
ADDTN_INFO_KEY_TYP_NM VARCHAR2(50),
     ADDTN_IDENTIFIER_VALUES T_T_ADDTN_IDENTIFIER_VALUES
CREATE OR REPLACE TYPE T_O_ADDTN_IDENTIFIER_VALUES
AS OBJECT
ADDTN_RQST_VALUE VARCHAR2(50),     
ADDTN_RQST_VAL_DT TIMESTAMP(6),
ADDTN_RQST_VAL_NUM NUMBER(19, 2)
I have pasted the query here from my function. when i pass the null as part of input for these 2 types my query is working. otherwise it is saying invalid Identifier.First I tried with first Type.
I am passing the value as
(PRKYTP.PRTY_KEY_TYP_NM = ITTPRC.PARTY_KEY_IDENTIFIER.PARTY_KEY_TYP_NM OR ITTPRC.PARTY_KEY_IDENTIFIER.PARTY_KEY_TYP_NM = 'ALL' OR ITTPRC.PARTY_KEY_IDENTIFIER.PARTY_KEY_TYP_NM IS NULL);
Error is Error(34,147): PL/SQL: ORA-00904: "ITTPRC"."PARTY_KEY_IDENTIFIER"."PARTY_KEY_TYP_NM": invalid identifier

can some one tell is this approach is correct. if not suggest me.

Answer 1

I am passing the value as
(PRKYTP.PRTY_KEY_TYP_NM = ITTPRC.PARTY_KEY_IDENTIFIER.PARTY_KEY_TYP_NM OR Here PART_KEY_IDENTIFIER is a Nested table. So you cant join it like that.
Try like this
prkytp.prty_key_typ_nm in (select party_key_typ_nm from table(ittprc.party_key_identifier)) orHere is a example based on EMP table.
I have created following nested table.
SQL> create or replace type my_emp_list as table of number(10)
  2  /
Type created.
SQL> create or replace type my_dept_obj as object(deptno number(10), emp_list my_emp_list)
  2  /
Type created.
SQL> create or replace type my_dept_tbl as table of my_dept_obj
  2  /
Type created.I am going to use the below nested table data in a query to get value from emp table
my_dept_tbl
   my_dept_obj
     10, my_emp_list(1,2,3,4,5)
   my_dept_obj
     20, my_emp_list(6,7,8,9)
)The query would be like this
SQL> select e.*
  2    from emp e
  3    join table
  4         (
  5           my_dept_tbl
  6           (
  7             my_dept_obj
  8             (
  9               10, my_emp_list(7839,7782)
10             ),
11             my_dept_obj
12             (
13               20, my_emp_list(7566,7369)
14             )
15           )
16         ) t
17      on e.deptno = t.deptno
18     and e.empno in (select column_value from table(t.emp_list))
19  /
     EMPNO ENAME  JOB              MGR HIREDATE         SAL        COM     DEPTNO
