In PL/Sql, I create a new collection using TYPE. Then populate it with BULK COLLECT.The next step I need is to load data from the collection to pass as WHERE condition to a ref cursor.How I can do this?Every test I did fais. It seems to me that I cannot use some kind of SELECT to retrieve all data from the collection, but I might use a cursor to read row by row. (I'm on Oracle 11gR2 DB )

What is the advantage of collections over CURSOR? What is the use for collections and when collections is used?
View 1 Replies View RelatedI have an existing Procedure that uses a ref cursor as a parameter. The procedure currently simply selects data into the ref cursor using an OPEN FOR and then exits.
I have a need to extend the processing of the procedure. This will mean retrieving extra columns in the select and also removing some of the retrieved records.
I have the constraint that the definition of the REF CURSOR (which is based on a record type as follows) cannot be modified.
TYPE t_charge
IS
RECORD (
id number,
date_from invoice_detail.from_date%TYPE,
date_to invoice_detail.to_date%TYPE,
description invoice_detail.desc_text%TYPE,
amount invoice_detail.amount%TYPE
);
TYPE t_charge_cursor IS REF CURSOR RETURN t_charge;
The procedure does this
PROCEDURE get_bill_lines (
p_bill_id IN NUMBER,
bill_lines_list OUT t_charge_cursor )
IS
OPEN bill_lines_list FOR
SELECT id, from_date, to_date, desc_text, amount
from invoice_table
where id = p_bill_id;
I am thinking instead of selecting directly into the bill_lines_list parameter I will use a local REF CURSOR to select into a COLLECTION. I can then do some work on the collection, similar to below:
PROCEDURE get_bill_lines (
p_bill_id IN NUMBER,
bill_lines_list OUT t_charge_cursor )
TYPE t_local_charge
IS
RECORD (
[code].....
This all works fine, but the question is, how do I then put the collection into the bill_lines_list REF CURSOR where the '*** HERE ***' comment is so I can send the existing REF CURSOR structure back? (Remember I cannot change any definition that is referenced externally)
I've create two types:
create or replace type VAL_REC as object
(WAARDE number(20,5) ) ;
create or replace type VAL_TAB is VARRAY(200) of VALREC ;
create or replace type WSN_REC as object
( START_DATE date
, END_DATE date
, DATA VAL_TAB) ;
create or replace type WSN_TAB as table of WSN_REC ;
In a PL/SQL table collecton WSN_TAB is filled. Now I want to create a query (ref cursor) that gives the result:
START_DATE END_DATE WAARDE(1) WAARDE(2) WAARDE(3) etc.

I am using regexp_substr to break the pipe delimited string. Want to use the output as the NUMBER input to a cursor.Its not working and not getting any error also.
Here is an example.
initial input : '5545|4124|12456'

I am describing a SQL statement to get it's column list:DECLARE
cur NUMBER;
col_cnt INTEGER;
rec_tab DBMS_SQL.DESC_TAB;
[Code]....
Now I need to get out the columns list from rec_tab.col_name and put it to my_colls collection. Have Oracle any build-in to do that?
I'm dealing with an ORA-1000 error in a Pro*C application where all the cursors are correctly closed (or so it seems to me).
Here is the code for a simple program which reproduces the problem:
Each cursor is opened in a PL/SQL package:
CREATE OR REPLACE PACKAGE emp_demo_pkg AS
TYPE emp_cur_type IS REF CURSOR;
PROCEDURE open_cur(curs IN OUT emp_cur_type, dept_num IN NUMBER);
END emp_demo_pkg;
[Code]....
While testing the initialization parameter open_cursors is set to 50.
It's my understanding that Oracle doesn't close the cursors until it needs the space for another cursor, which in my test case seems to happen when I enter a value of 50 or bigger for "number of loops". To see how oracle is reusing the cursors, while the test program is running I run SQL*Plus and query v$sesstat for the session that's running the test with the following sentence:
select name, value
from v$sesstat s, v$statname n
where s.statistic# = n.statistic#
and sid = 7
and name like '%cursor%';
Even before I enter a value for number of loops I can see that the session opened 4 cursors and closed 2 of them:
NAME VALUE
---------------------------------------------------------------- ----------
opened cursors cumulative 4
opened cursors current 2
Entering a value of 5 for number of loops yields
NAME VALUE
---------------------------------------------------------------- ----------
opened cursors cumulative 11 <----- 7+
opened cursors current 8 <----- 6+
With a value of 30
NAME VALUE
---------------------------------------------------------------- ----------
opened cursors cumulative 36 <----- 25+ (apparently, Oracle reused at least 5 cursors)
opened cursors current 33 <----- 25+
With a value of 47
NAME VALUE
---------------------------------------------------------------- ----------
opened cursors cumulative 53 <----- 17+
opened cursors current 50 <----- 17+
Now I reached the upper limit set by the initialization parameter open_cursors.
Entering a value of 48, I get the ORA-1000 error.
ORA-01000: maximum open cursors exceeded
ORA-06512: at "SCOTT.EMP_DEMO
Since I open and close the cursor in the same loop iteration, I expect to find in every iterarion 1 explicit cursor and a number of implicit cursors (the PL/SQL call along with the so-called recursive cursors), but I don't expect the sum of all of them to be greater than 50. If my understanding is correct Oracle should be reusing the 50 cursors previously marked as "closeable", not raising the ORA-1000 error.
Is it possible to:
-define a cursor with bind variables
-get a cursor record from these cursor
-and pass the bind variable in the OPEN clause
Did'nt succeed as shown in the example.

I need to check if a small collection contains a specific value. I know I can use the .exist method to let me know if the nth element exists. But is there a similar syntax for checking if an actual value exists?
So the below collection has 6 values (300,301,310,320,400,410) after the cursor values are fetched. I want to use something similar to the below exists syntax in order to search the collection for a value (rather than position) within an IF statement.
The below code shows the kind of thing I want to do. Currently, unless my test value (310) is in the range 1 to 6 the test will always return FALSE. But is there a similar syntax for testing against the value?
The example I have given is a simplification of what I need. In reality there will be more than one test value... returned by another cursor.
