CREATE OR REPLACE TYPE GET_EMP_OBJ is object
( emp_name varchar2(50) ,

[Code]...
The above function got created successfully. And i'm confused how to call this functions. I tried like below but didn't work
DECLARE
t_emp_info_1 GET_EMP_OBJ ;
BEGIN
t_emp_info_1 := get_emp(7566) ;
for i in 1..t_emp_info_1.COUNT
LOOP
DBMS_OUTPUT.put_line ('Values are'||i.emp_name ) ;
END LOOP;
END;
I have two Oracle instances, both are 10.2.0.3
Executing the following results in two different results:
select N'Test" "result" from dual;
On one the output is:
resu
----
Test
and on the other the output is
result
----------------
Test
This seems to suggest that one is returning "Test" as a char(16) and the other as a varchar2 or nvarchar2. In both cases, NLS_CHARACTERSET is WE8ISO8859P1 and NLS_NCHAR_CHARACTERSET is AL16UTF16.
Not being an Oracle DBA, I am not sure where to look.
Oracle 11g For a procedure, if I use the hard-code procedure
sp_test( p_rc out sys_refcursor, p_1... p_2 ... ) is begin open p_rc for select * from TEST_TABLE... But now, I want to use the dynamically constructed sql, such as if condition1 then v_sql := ... elsif condition2 then v_sql := ... execute immedite v_sql
How can I return the the cursor p_rc in this case?
I have created a object type as
create type emp_obj_dtl as OBJECT (ename varchar2(50),mgr NUMBER)
create type emp_dtl_obj_typ as TABLE of emp_obj_dtl
Using the these object i have created on function as
CREATE OR REPLACE FUNCTION emp_test_func (peno NUMBER)
RETURN emp_dtl_obj_typ
AS
lv_emp_dtl emp_dtl_obj_typ := emp_dtl_obj_typ ();
BEGIN
SELECT emp_dtl_obj_typ(emp_obj_dtl (ename, mgr))
INTO lv_emp_dtl
FROM emp
WHERE empno = peno;
RETURN lv_emp_dtl;
END;
Now if i am executing query as
SELECT empno, emp_test_func (empno) emp_dtls
FROM emp
It is returning me the data as
EMPNO | EMP_DTLS
7500 | (DATASET)
7382 | (DATASET)
7569 | (DATASET)
7800 | (DATASET)
But I want the result set as
EMPNO | ENAME | MGR
7500 | SMITH | 7863
7382 | JAMES | 7896
7569 | KING | 7856
7800 | SANGR | 7456
How to get the resultset as above.
I am trying to create a function which would return a nested table with 3 columns of a table as a type.
my query is like
select col1,col2,col3 from table_1;
I have the following database function.
GetRegionDetails(id in varchar2, o_lat out number, o_lon out number);
The problem is, the output values are returning as whole numbers ie. 38.108766567 is being returned as 38 and -78.16423574566 is returned as 78
what data type I should use so that my output is returns all the decimal values?
I have strange problem when i try to return a ref cursor holding data from a select on a oracle global temporary table. If i iterate through the cursor , i can see the values but the function as such returns nothing through the ref cursor. I tried the temporary table as both delete on commit and preserve on commit
create or replace
PACKAGE BODY BILL AS
FUNCTION FILTERI RETURN BILL.refcursor IS
testcursor BILL.refcursor;
ttstatus INT;
iSuccess INT;

How to call a function with a row type return in an Oracle select statement.
For e.g. :
If I had this function with a rowtype return:
------------------------------
create function abc
return xyz%rowtype
is
rec xyz%rowtype;
begin
select * into rec from xyz where col1 = n;
return rec;
end;
--------------------------------
How could I use this in a select clause, as there is a multi column return by the function ?
I'm currently using Oracle 11.2G and I was wondering if you can declare a dynamic cursor as a strong ref cursor type or can it only be declared as weak type ref cursor? Now, if it can only be declared as a weak type ref cursor, is there any way to avoid having to explicitly declare the type and field names being returned by the cursor? Meaning, is there anyway to avoid have to do something like this...
TYPE example_rec IS RECORD
(
col1 VARCHAR2,
col2 NUMBER,
col3 NUMBER,
etc...
)
Instead, I was wondering if I could just set the fields and their types by setting them as a TABLE OF the ref cursor? The reason I'm wondering if this is possible is because I have a lot of fields being returned in my cursor, and I was hoping on avoiding having to type each one out and its type.
we use oracle 11g. 11.2. I have a situation where in a pl-sql package, there is a modification needs to be done . Every User is associated with destination codes. For eg, user1==>0101,0104 There is a destination_number and country field in the table1.Each of the destination number is associated with a country code and this combination is unique. for eg:
dest_code country_code 0101 CHINA 0202 UK 0101 Mexico 0104 Mexico
For example, if user1 logs in to the system, then pl sql logic will look if that dest_code is in a table1,If the dest_code is present in the table1, then that dest_code number wont be added to the dest_code list formed for that user. For example,if user1 got dest_codes 0101,0104 associated with him.IF 0101 is in exception table then 0101 and 0104wont be used to form dest_code list. If NOT, a dest_code list will formed like 0101||0104. I am able to form the logic like I have a cursor that loops for each dest_code.For each dest_code , it will get that dest_code into v_dest_code_no number type variable. open cursor fetch dest_code no into v_dest_code v_dummy number:=0;v_dest_code_list number:=0; LOOP v_dest_code_list:=v_dest_code ||v_dest_code ; v_dest_code :=0; END LOOP: How to make sure that for each dest_code set, if one of them is in table1, then the next number also will not be added to the list.

1. If i'll do drop type FORCE what will happen to the dependent object(might be a table for example) ?
2. I understand that this type is already assigned to some object, but i can't seem to find out which one.
how do i find out which object is depending on the type i want to create or replace?
I have created the below types and oracle objects.
create or replace type T_SETDEL_RESP_REC as object
(
respCode number,
respDesc varchar2(255)
)
--
create or replace type T_EMA_NP_RANGE_LNPTICKET_REC as object
(
ticket number
)
create or replace type T_RANGE_TICKET_TAB AS TABLE OF T_RANGE_TICKET_REC
The following type is created in the Package specification
type t_resp_rec IS RECORD
(
resp_code number,
resp_desc varchar2(255)
);
I have the following two procedures
Procedure getResponse(p_call_request_id IN number, p_resp_rec IN t_setdel_resp_rec,
p_range_ticket_tab IN t_range_icket_tab, p_endof_event IN varchar)
PROCEDURE ProcessResponse(p_call_request_id IN number, p_resp_rec IN t_resp_rec,
p_ticket_tab IN t_ticket_tab, p_endof_event IN varchar2)
The get Response procedure is a wrapper procedure exposed to Java to pass values. The Process Response procedure is a main procedure where all logics and business rules are handled.
The Problem is:
How can I pass the values from get Response procedure to Process Response procedure. So that rules and validations are applied. Please note the p_ticket_tab may have many ticket numbers corresponding to p_call_request_id.
Values E.g. :
p_call_request_id = 1
p_resp_rec (1234, 'Error found')
p_range_ticket_tab (1,2,3,4,5)
p_endof_event = 'Y'

View 4 Replies View RelatedI'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.
SET SERVEROUTPUT ON SIZE 900000;

--works fine
CURSOR c1 IS SELECT * FROM USER_TABLES WHERE rownum<3;
--doesn't work

I'm new to this XML DB thing and also this is my first post.
I'm trying to populate collection type from XMLType. I was able to populate a table from XMLType but any way to populate the collection type. Here is the description of my problem:
Object Type:
CREATE OR REPLACE TYPE DOC_ROWTYPE AS OBJECT
(
REFERENCENUMBER VARCHAR2(255),
REQID NUMBER(12),
[Code]....
Collection Type:
CREATE OR REPLACE TYPE DOC_TABLETYPE IS TABLE OF DOC_ROWTYPE;
I have a physical table which is created when I registered a schema.
A table (Temp_Result) got created with column SYS_NC_ROWINFO$ which is of XMLType.
As you can see this is only a temporary table which will store the response XML which I want to finally get it to collection type.
XML to parse:
<code>
<TFSResponse>
<TFS>
<refNumber>12345</refNumber>
<reqId>123</reqId>
[Code]...
So each object in the collection is one TFS tag. how to implement this?
just looking around to use the new feature available in oracle 11g to convert the dbms_sql numeric cursor to reference cursor, how to do it?
parse and execute the sql string first with dbms_sql and then convert it to ref cursor?
