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.

I need to display the data as range , i have created one table along with inserts as below , i need the desired output as mentioned below.The range will start from field STMH_PM_CODE , it will get the first and last stmh_pm_code and stmh_pm_desc which are in the same combination of STMH_NO,STMH_JOB_NO,STMH_batch_no and stmh_rev_no,

-- i want it as below see the line in stmh_pm_desc the description gets added until there is a change in either stmh_batch_no or stmh_rev_no since we have stmh_pm_code 1107040-1004 with stmh_batch_no 0002 it goes to other line as a seperate new range and first one will stop with 1107-1003 as that is the last combination and new line or range will get added over again.
Updated to Add: In a last ditch search, I found my answer with ROWNUM <= 1 in the Where clause. It works and I can go from there with what I want to do.
I have a website that pulls similar information from multiple queries using a Union-based query. I want to only pull 1 record from one section, two from another, and 5 from the third. I've so far found LIMIT but haven't been able to get it to work in that way. Is it possible to limit each query in the union as I am looking to do?
The query is:
SELECTc.priority, c.startDate, p.headline, p.newsID, p.kicker, p.webPath, p.makePopup, p.thumbnail, p.shortDesc, p.storyType, d.filePath FROM (so_news p LEFT OUTER JOIN so_news_deptLevel c ON p.newsID = c.newsID) LEFT OUTER JOIN so_departments d ON d.deptID = c.deptID WHERE p.storyType = 'alert' AND c.display = 'yes' AND c.startDate <= sysDate AND c.endDate >= sysDate UNION All SELECTc.priority, c.startDate, p.headline, p.newsID, p.kicker, p.webPath, p.makePopup, p.thumbnail, p.shortDesc, p.storyType, d.filePath
I have made a correlated update statement using rowid. Find my attachment. Its updating all columns which i wanted but issue is that its not updating in 1st commit.
Suppose 6 rows is to be updated, then in 1st commit its updating 1 record, then in 2nd commit its updating 2nd record and so on. And in Toad its showing 6 rows updated in 1st commit, then 5 rows updated in 2nd commit and 1 rows updated in last record. I want that all records to be updated in first commit only.
What would be the best way to Commit after every 10 000 records inserted from one table to the other using the following script :
DECLARE l_max_repa_id x_received_p.repa_id%TYPE; l_max_rept_id x_received_p_trans.rept_id%TYPE; BEGIN SELECT MAX (repa_id) INTO l_max_repa_id [code].........
1. My detail form has part number as one of the fields and I want to make sure the user can enter a part number only once. How can I make sure user cannot enter it more than once?
2. I want to limit number of detail records for every parent record to 8. How can I accomplish this?
3. I have approval flags at both master and detail. If the user tries to approve the master with some/all detail records unapproved, system should display error message and make the user approve the detail before approving the master.
Oracle DB Version - 11g XE I scheduled a job using dbms_scheduler which will insert a record into table T for each minute. I didnt mention COMMIT inside my procedure but records are being commited after each successful execution. How come it is possible. Here is my code.

I am writing a query where I need to get the total points the student received on assignments, this is in the grade table. I then need to divide that total from the total amount of points possible, located in the assignment table. At the end all I should see is the student_id and the percentage of the students grade.
Here is where I am so far
SELECT s.student_id, SUM(g.points)/SUM(a.points_possible) "GRADE" FROM student s, grade g, assignment a WHERE s.student_id = g.student_id AND g.assignment_id = a.assignment_id ORDER BY student_id;
However when I execute this is the error I get:
WHERE s.student_id = g.student_id * ERROR at line 3:
ORA-00937: not a single-group group function The asterisk's should be under the g I couldn't get it to line up.
I need to divide the given time period into weeks from Monday to Sunday .There should not be overlapping of two months, for a week.Every month should start from First day of that month to next Sunday .Same thing can be done by following PL/SQL block . let me know if there is any simple way by using query instead of 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.
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.
DECLARE TYPE weak_cur_type IS REF CURSOR; weak_cur_1 weak_cur_type; weak_cur_2 weak_cur_type; vs_dsql VARCHAR2(2048); vd_create_time DATE; vn_count NUMBER(8); vn_total_amount NUMBER(13);

[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 am having a table with 4 columns as mentioned below
For a particular prod the value greater less than 5 should be rounded to 5 and value greater than 5 should be rounded to 10. And the rounded quantity should be adjusted with in a product starting with order by of rank with in a prod else leave it
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 AS TYPE cur1 IS REF CURSOR; PROCEDURE get_empdetails (p_empno NUMBER, io_cur OUT cur1); END;
[code]...
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' ?
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.
-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've written a .net program for inserting blobs into our database, and it works fine, except if the path has more than 30(+) characters. I've read that this is a limitation in oracle, but the actual contents being stored is just the filename, extension, and blob itself, so I'm not actually storing anything more than 30 characters.
Working on building an application which will be in C# (.NET 3.5) and some PL/SQL. However, for the tables which have to store the data, I added a column, comments, to the table and assigned it a data type CLOB. No big deal, except my PL/SQL function is giving me errors if the CLOB built from several varchar2 rows exceeds 4000 characters. I understand the varchar2 field is restricted in 10g, but I was under the impression there wasn't such a restriction on a CLOB (hence the reason we're using it.)
I end up getting:

I want to write a procedure in such a way that the code in the proceduce should finish its work with in a given amount of time other wise it should exit from the procedure.
For example....
i am fetching data from a table and inserting into another table and i want ot finish this task within 10 mins if it does not i need to exit from the procedure.
