I have created one global temporary table in which I inserted 2 rows.
I am fetching the rows by using following cursor :
declare
cursor c1 is
select TTD_TRV_MODE
from global_tra_trv_dtl;
v_trv_mode varchar2(10);
Begin
open c1;
[code]....
But instead of 2 rows , 3 rows are getting fetched.

CREATE OR REPLACE PROCEDURE test_rdm_miles (
p_ref_cursor OUT SYS_REFCURSOR
p_success NUMBER)
IS
BEGIN
OPEN p_ref_cursor FOR
SELECT 5168 mem_uid,
[code]....
I have a Procedure with out parameters as a REF CURSOR and response message as p_success.This ref cursor will be returned to the calling service. Is there a way in oracle by which we can identify whether the Ref cursor holds data without actually fetching it. Since if i choose to fetch the data, i will lose one row when i return the ref cursor back to the calling service Or else is there way i can retrieve the row i lose during fetch.
Other alternative what have been suggested is create an object type ,fetch the ref cursor values in object type. Then i can use the ref cursor to return the data by table casting.
one more solution is
OPEN
FETCH
CLOSE
OPEN (AGAIN) { this will lead to redundancy)

I have a cursor in my procedure. When I OPEN, FETCH, it doesnt give me any values. But instead of cursor,if I use the sql , used in the same cursor, then i am getting the value.
DECLARE
l_vin CLM_MAIN.vin%TYPE;
l_part CLM_MAIN.vin%TYPE;
l_clm_id CLM_MAIN.vin%TYPE;
[Code]....
Clm_main has a UNIQUE constrains, of VIN, PART. So when i OPEN the cursor, its not finding clm_id , eventhough it exist in the table. so it takes it as claims_cur%NOTFOUND, an tries to INSERT in the table. But since the record with that VIN and PART already exists, it throws exception that ORA-00001: unique constraint (CLM_MAIN_UK) violated.
This is the cursor which fetches from View uk_case_recommends_vw and this view calls the table ukcc_case_casenames below is the query
cursor cur_case_name_search is
select a.*,DENSE_RANK() OVER (ORDER BY sc desc) rank
from uk_case_recommends_vw a
where rownum < 2 + 3;
SELECT
/*+first_rows(4) index(u ukcc_case_casename_idx)*/
persistentid,
casename,
FROM ukcc_case_casenames
Here in this table my case name may be with special character or normal .
For Ex ('R V Wilson') - With Special character
('R V Wilson') - Without Special character
Actually my cursor is not fetching with special character ..neither it is not mentioning as no data found. Find the piece of code below.. I am not getting values after opening the cursor.
open cur_case_name_search;
loop
fetch cur_case_name_search into v_case_name_row;
exit when cur_case_name_search%notfound or
v_case_name_row.rank > v_matchingvalue or

I have used a dynamic cursor for fetching value from different tables hence table name assigned dynamically during run time but i face an error ORA-06562 type of argument must match type of column and bind variable with error ORA-06212 But i frequently check the table structure and Declared variable there is no mismatch between them.

The above query is not returning any value. But, when I put this within a begin-end block, its fetching data.
why its not returning any data without the begin-end block.
The entire code has an outer begin-end block within which the cursor is also defined.

Now when there records in READING_DWR are 1 lakh, i am getting the o/p in 10 sec.
However when there are bulk records, it is taking 3 to 4 min.
Is there any way to improve my query performance?
I have a Select query which is not fetching records in 11g (11.2.0.2.0) but working fine in 10g (10.2.0.4.0). The query is as below.
--CREATE TABLE t1 (col1 NUMBER, col2 VARCHAR2 (15 CHAR), flag varchar2(1))
--insert into t1(col1, col2, flag) values(1, 'a', 'Y');
--insert into t1(col1, col2, flag) values(2, 'b', 'N');
SELECT *
FROM t1 x
WHERE col1 = 1 AND col2 = 'a' -------------- condition1
AND 0 = -------------- condition2
NVL (
(SELECT COUNT (1)
FROM t1 y
WHERE y.flag = 'N'
AND x.col1 = y.col1
AND x.col2 = y.col2),0)--=0
When remove NVL function or change the condition by having AND NVL(SELECT) =0 the query working fine.
I wrote the following block :
set serveroutput on
declare
rec employees%rowtype;
cur SYS_REFCURSOR;
begin
open cur for 'select * from employees where rownum<:a' using 4;
for i in cur
[code]....
It gave errors if we execute is as such, but worked when I commented out the for loop and instead de-commented the simple loop. Does that mean that FOR cannot be used to loop through the records of a ref cursor ?
I wrote the function witch returns some information.
function get_cust_info (v_msisdn integer) RETURN sys_refcursor
IS
curs sys_refcursor;
BEGIN
open curs for 'select first_name, last_name, street, town
from the_table where MSISDN = :1' using v_msisdn;
RETURN curs;
end
How to call this function to write result into table? I just want to write function which returns more Varchar.
I have to optimize a batch job which returns > 1 lakh records . I have a commit limit being passed . I am planning to divide the cursor records for processing as follows. If the cursor suppose returns 1000 rows and the commit limit passed is 200 , then i want to fetch 200 records first , bulk collect them into associative arrays and then bulk insert into target table.
After this is done, i will fetch the next 200 records from the cursor and repeat the processing. I would like to know how i can divide the cursor records, and fetch "limit" number of records at a time and also be able to go to the next 200 recs of the cursor next time.
After opening a dynamic cursor, usually fetch hit record into some variables. However, if I do not want to "FETCH INTO " operate Just only skip this record.

I have taken all the records in to a cursor. Once after rounding the request of 1st rank and adjusting the values of next rank is done. Trying to round the value for 2nd rank as done for 1st rank. Its not taking the recently updated value(i,e adjusted value in rounding of 1st rank).
This is because of using a cursor having a value which is of old value. Is there any way to handle such scenario's where cursor records gets dynamically updated when a table record is updated.
i have a ref cursor and i have used 'open cursor for' statement:
CREATE OR REPLACE PACKAGE aepuser.pkg_test

END;

then i want to know that- will oracle automatically deallocate the memory occupied by records in cursor area?if yes, then when it will be free , in case of 'open cursor for' ?

View 3 Replies View RelatedI wanted to fetch a records from a table with no. of records and segment_name,owner,size of the table.So, i wrote a query like,

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;

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.
