I have come across a code where i need to know exact logic for the use of FOR UPDATE and COMMIT used in a cursor.The code is like :
Declare
Cursor c1 is select * from emp FOR UPDATE;
Z c1%rowtype;
Begin
Open C1;
Fetch c1 into Z;
dbms_output.put_line(z.ename);
Commit;
Fetch c1 into Z;
dbms_output.put_line(z.ename);
end;
When i run above code, i get error as below, but first value from table emp i.e. emp.ename is displayed :
Error at line 1
ORA-01002: fetch out of sequence
ORA-06512: at line 9
But when i run by removing FOR UPDATE, i get first 2 values displayed without any error message:
Declare
Cursor c1 is select * from emp;
Z c1%rowtype;
Begin
Open C1;
Fetch c1 into Z;
dbms_output.put_line(z.ename);
Commit;
Fetch c1 into Z;
dbms_output.put_line(z.ename);
end;
I need to write a script which copies 4 col data from one table to another table. there are three tables
cwat_curr_mst and cwat_assigned_customer and cwat_assignment_mst. Cwat curr mst has PK curr_id and cwat_assigned_customer has PK assignment_id. Also cwat_assigned_customer has customer_id. In cwat_assignment_mst has Curr_id and Assignment_ID.
cwat_curr_mst and cwat_assigned_customer tables has 4 cols in common they are ASRT_SNM_NO, SNM_NO, FLORIDA_NO, CBRN_NO.
So from curr_mst all these 4 cols data needs to come/copy into cwat_assigned_customer.
for Inserting records created below cursor, records are inserted and I can see on my screen (form) also.
DECLARE CURSOR InvestIS select * from Tempinvest; BEGIN OPEN Invest; GO_BLOCK('ReturnReport'); last_record; [code]......
2nd step:-
Updating records I wan to update some columns in this table so I created a 2nd cursor to update records but this cursor is not working accordingly. my requirement is: before Update first of all Find inv_co_code & inv_fnd_code when find then update column Redunits
2nd Cursor
DECLARE ddate date; refdate date; co_code number; co_name varchar2(50); fnd_code number; fnd_name varchar2(50); units number; amount number; stat varchar2(1); CURSOR bnr IS

I'm currently facing a non-critical situacion while trying to update a table. Here's the PL/SQL Code. It's a pretty straight-forward script, It just update one single column of the table. The only problem is that I have to update over 15 milions records. When I use the for update cursor, I put inside the loop a counter, when it reaches 1000 records, then commit, else keep counting.
The block throws the exception ORA-01002: fetch out of sequence.
I've tried to do some reserch on Google, buy it only says it is an out of secuence fetch caused by a commit inside a for update cursor.
My question is. Is there any risk by putting the commit under the end loop, I mean by doing this I'd be updating over 15.000.000 records at the same time. Will I have any issue with the rollback segment ?
Here's the code as along with the Create Table and Insert statements.
CREATE TABLE TEST_1 ( TEST_ID NUMBER PRIMARY KEY, IS_LOCKED NUMBER NOT NULL );
INSERT INTO TEST_1 (TEST_ID, IS_LOCKED) VALUES (1, 0);
I would like to update the particular employee name by using the cursor ..For that I would like to show the steps which I did . as in the below screen it updated John but it removed the other ename ...I like to update John only and remaining ename should be as it ..
The code which I have written on KEY-COMMIT is below.
i have two tables test1 and test2. i want to update the column(DEPT_DSCR) of both the tables TEST1 and TEST2 using select for update and current of...using cursor.
I have a code written as follows :
DECLARE v_mydept1 TEST1.DEPT_CD%TYPE; v_mydept2 TEST2.DEPT_CD%TYPE; CURSOR C1 IS SELECT TEST1.DEPT_CD,TEST2.DEPT_CD FROM TEST1,TEST2 WHERE TEST1.DEPT_CD = TEST2.DEPT_CD AND TEST1.DEPT_CD = 'AA' FOR UPDATE OF TEST1.DEPT_DSCR,TEST2.DEPT_DSCR; [code].......
The above code when run says that it runs successfully. But it does not updates the desired columns[DEPT_DSCR].
It only works when we want to update single or multiple columns of same table...i.e. by providing these columns after "FOR UPDATE OF" I am not sure what is the exact problem when we want to update multiple columns of different tables.
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'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 have a base table (Table A) block with multiple records displayed. I need to track audits to this underlying table in the following way:
If user updates a field in the block I want the pre-changed record's audit fields to be set and I need to create a copy of the record with the changed values. Basically any changes will result in the record being logically deleted, and a copy record created with the newly changed values.
Tried to implement in the block's pre-update trigger which will call a package to directly update Table A then Insert into Table A, then requery the block. Is there a clean and efficient way to do this?
UPDATE t_tt_hours a SET a.sak_request = ( SELECT b.sak_request FROM t_requests b, co c
[Code]...
The problem I am having is that it is updating all rows even when it is pulling back a null value for b.sak_request. I've tried adding b.sak_request is not null to the select statement like this:
UPDATE t_tt_hours a SET a.sak_request = ( SELECT b.sak_request FROM t_requests b, co c WHERE b.nam_eds_tracking_id = c.id_dir_track_eds
[Code]...
but it doesn't seem to make a difference. The reason I need to do this is that the difference between where it matches with a valid (non-null) value is 396 rows vs. 12,484 rows which is too time consuming to run on my page.
i want to create a trigger that will update a table when there is an insert or update.i can't across this error that i don't even know what it means "table %s.%s is mutating, trigger/function may not see it".
*Cause: A trigger (or a user defined plsql function that is referenced in this statement) attempted to look at (or modify) a table that was in the middle of being modified by the statement which fired it.
*Action: Rewrite the trigger (or function) so it does not read that table.
CREATE OR REPLACE TRIGGER set_date_end BEFORE INSERT OR UPDATE OF issued ON shares_amount FOR EACH ROW DECLARE BEGIN INSERT INTO shares_amount(date_end) VALUES(SYSDATE); END set_date_end; /
i am reading the columns value from different table but i want to update it with single update statement. such as how to update multiple columns (50 columns) of table with single update statement .. is there any sql statement available i know it how to do with pl/sql.
insert into test_compound values ('user1','1',systimestamp); insert into test_compound values ('user2','2',systimestamp-4); insert into test_compound values ('user3','3',systimestamp-6);
CREATE OR REPLACE TRIGGER trigger_test FOR UPDATE ON test_compound COMPOUND TRIGGER TYPE t_tab IS TABLE OF VARCHAR2(50); l_tab t_tab := t_tab(); [code].......
When I execute :
update test_compound set last_updated_on=systimestamp where userid='user1' and app='1';
The trigger should update the first row and all the data from test_compound table where userid='user1'. Maybe the problem is that updating the same table inside the trigger is firing in a recursive way the trigger.
I have a column "empno" in EMP table and "deptno" in DEPT table . I want to update both the columns with single UPDATE statement. With out a creation of stored procedure or view(updating it through view).

We receive hand punches (clock data) every day. Normally a person badges in(hand punch) which creates a row in the clock_tran_processed table. The information from that hand punch is the employee id (emp_id) the date hand punch occurred and a work_summary id (wrks_id). At the end of the day, the employee badges out (hand punch out) and another entry in the clock_tran_processed table is created. The new row will have the emp_id (employee name), date the hand punch occurred and the same work summary id from the morning.
Normally hand punches should occur in pairs. One in, one out... or one in, out for lunch, in for lunch, out for day. I am seeing intervals of three and five. Meaning the employee clocked in twice and out once, or in once and out twice. This shouldn't happen.
I am writing a report that will show number of clocks per for all employees that have three(3) or five(5) clock entries.I wrote a ref cursor that gives all the employees that have a count of 3 or 5 and the employee id (emp_id). I need to pass that employee id to another query that will then get me the dates of the clocks.Here is the ref cursor thus far (I am printing those with a count of 3 and 5).

How do I pass that variable to the get the clktranpro_time's? I am using "Easy Oracle PL/SQL Programming" but I am not seeing this type of example(pgs 140-148).
In our environment we have db link to fetch data from other database. Whenever we try to fetch data using the dblink we receive the wait event "cursor: pin S wait on X" and we do not get any result. The db link works fine. what could be the issue.

I would like to know whether a value obtained from one cursor can be passed to the other cursor as a parameter and by passing it i want to retrieve a list of records and print only the records obtained from the second cursor where the value is passed.
