How to create an oracle stored procedure with an array parameter - oracle

Question

I créated an Oracle stored procedure into a package. I did like this:
CREATE OR REPLACE PACKAGE PACKFACE IS
TYPE LIST_IDS IS TABLE OF INT INDEX BY BINARY_INTEGER;
PROCEDURE P_SELECT_IDBFRIENDS (CONSULTA OUT SYS_REFCURSOR,COD_US IN INT,IDS_NOT IN LIST_IDS);
END;
And the body of the package is:
CREATE OR REPLACE PACKAGE BODY PACKFACE IS
PROCEDURE P_SELECT_IDBFRIENDS (CONSULTA OUT SYS_REFCURSOR,COD_US IN INT, IDS_NOT IN LIST_IDS) IS
BEGIN
OPEN CONSULTA FOR
SELECT ID_US1,ID_US2 FROM T_FRIENDSHIP WHERE ID_US1=COD_US AND ID_US2 NOT IN (SELECT COLUMN_VALUE FROM TABLE(IDS_NOT));
END;
END;

These is ok in my Oracle 12c server, but I did the same code in Oracle 11g appeared an error, cannot access rows from a non-nested table ítem. What would be the solution? Thanks in advance
After this problem was fixed. Appears other one my Python code was broken. I have this procedure:
def select_ids(self,cod_us,ids_not):
lista = []
try:
cursor = self.__cursor.var(cx_Oracle.CURSOR)
varray = self.__cursor.arrayvar(cx_Oracle.NUMBER,ids_not)
l_query = self.__cursor.callproc("PROC_SELECT_IDS_ENT_AMISTADES", [cursor, cod_us, varray])
lista = l_query[0]
return lista
except cx_Oracle.DatabaseError as ex:
error, = ex.args
print(error.message)
return lista
PLS-00306 wrong number or type of arguments in call to a procedure. It was ok using Oracle 12c. Thanks in advance again.

Answer 1

You cannot use a collection type defined in PL/SQL in an SQL query in Oracle 11.
If you want to use a collection in both SQL and PL/SQL then you will have to define it in SQL:
CREATE TYPE LIST_IDS IS TABLE OF INT;
Then you can do:
CREATE OR REPLACE PACKAGE PACKFACE IS
PROCEDURE P_SELECT_IDBFRIENDS (
CONSULTA OUT SYS_REFCURSOR,
COD_US IN INT,
IDS_NOT IN LIST_IDS
);
END;
/
SHOW ERRORS;
CREATE OR REPLACE PACKAGE BODY PACKFACE IS
PROCEDURE P_SELECT_IDBFRIENDS (
CONSULTA OUT SYS_REFCURSOR,
COD_US IN INT,
IDS_NOT IN LIST_IDS
)
IS
BEGIN
OPEN CONSULTA FOR
SELECT ID_US1,ID_US2
FROM T_FRIENDSHIP
WHERE ID_US1=COD_US
AND ID_US2 NOT MEMBER OF IDS_NOT;
END;
END;
/
SHOW ERRORS;

First of all you should to create an oracle type like this:
CREATE OR REPLACE TYPE LIST_IDS AS TABLE OF INT;
And after that you should to create the package with the procedure and a nested table in parameter like this:
CREATE OR REPLACE PACKAGE PACKFACE IS
TYPE LISTADO_IDS IS TABLE OF INT INDEX BY PLS_INTEGER;
PROCEDURE P_SELECT_IDBFRIENDS (CONSULTA OUT SYS_REFCURSOR,COD_US IN INT,IDS_NOT IN LISTADO_IDS);
END;
Finally you should create the body. You pass the data to nested table from oracle type like this:
CREATE OR REPLACE PACKAGE BODY PACKFACE IS
PROCEDURE P_SELECT_IDBFRIENDS (CONSULTA OUT SYS_REFCURSOR,COD_US IN INT, IDS_NOT IN LISTADO_IDS)
IS
num_array FACEBOOK.LIST_IDS;
BEGIN
num_array:=LIST_IDS();
for i in 1 .. IDS_NOT.count
loop
num_array.extend(1);
num_array(i) := IDS_NOT(i);
end loop;
OPEN CONSULTA FOR
SELECT ID_US1,ID_US2 FROM T_FRIENDSHIP WHERE ID_US1=COD_US AND ID_US2 NOT IN (SELECT COLUMN_VALUE FROM TABLE(num_array));
END;
END;
I did that and I got the solution to the python error wrong number or type parameters. Good luck.
