I have a question regarding using of collections in Oracle SQL functions.
There are definitions of types in package:
/* Types of package*/
create or replace PACKAGE "test" AS
TYPE type_record_1 IS record ( id_num NUMBER , timestamp_num NUMBER,value NUMBER);
TYPE type_table_1 IS TABLE OF type_record_1;
TYPE type_record_2 IS record ( id_num NUMBER , timestamp_num NUMBER,pValue NUMBER);
TYPE type_table_2 IS TABLE OF type_record_2;
END test;
Problem is in functions_2.
function_2 uses output from function_1.
The error message occurs when I try select in function_2.
Error message "local collection types not allowed in SQL statements".
Could you please help? What is wrong with using of collections in functions?
/*function 1*/
FUNCTION function_1
RETURN type_table_1
IS
table_1 type_table_1;
BEGIN
-- select values from
SELECT id_num, timestamp_num, value --type_record_1 (id_num, timestamp_num, value)
BULK COLLECT INTO table_1
FROM (
SELECT
l.id_num,
EXTRACT(hour from end_time) * 60 + EXTRACT(minute from end_time) as timestamp_num,
l.value
FROM INTERVAL_F l
WHERE id_num IN (SELECT id_num FROM table_rev)
);
RETURN table_1;
END function_1;
/*function 2*/
FUNCTION function_2
(
table_1 IN type_table_1
)
RETURN type_table_2
IS
table_2 type_table_2;
BEGIN
SELECT type_record_2(id_num , timestamp_num , pValue)
BULK COLLECT INTO table_2 FROM (
SELECT id_num
, timestamp_num
, value as pValue
FROM table(table_1) -- ERROR IS HERE
);
RETURN table_2;
END function_2;
