SQL & PL/SQL :: How To Fetch Two Times Same Explicit Cursor
Nov 25, 2012
I need to open an explicit cursor for making a total: after I have to use the same information of that explicit cursor for dividing a column of the cursor by that total. It is not enough to open close, reopen and reclose because I just obtain one register at the same time and it is the same register two times consecutively.
I don't want to use auxiliary structures cause there are 18000 columns for 10200 rows.
FOR i IN 300..300 --18000
LOOP
y:=ymax-ysize*(i+0.5);

I want to return ref cursor based on explicit cursors
create table jumbo(id number, name varchar2(20));
insert into jumbo values(1,'jumbo');
create table mumbo(id number, name varchar2(20));
insert into mumbo values(1,'mumbo');
commit;
[Code].....
The above procedure has compilation errors when I am trying to open ref cursor

what are the main points that these examples are considered cursors? and why are they called explicit and implicit cursor.
explicit
for x in (select * from emp) loop
dbms_output.put_line('emp no: '||x.empno);
end loop;
implicit
select empno
into vEmpno
from empno
where empname = 'SCOTT';
for all we know that these are not clearly defined on the declaration area as cursor.

difference between between these two constructs. Finally when i read the asktom.oracle.com , I was totally confused. The reason is thatTom says...we can retrieve more than one row in implicit cursor. If that would be case, what's the difference between these two cursors?? when to use?? My understanding was implicit cursors" ---> single-row queryExplicit cursors ---> multi-row query Experts

Oracle Version: 11.2.0.2.0. I have two explicit cursors and I would like to choose at run time which one to run. Here is a simplified code snippet of what I am doing today:
DECLARE
CURSOR Cursor_A IS
SELECT * FROM EMP_A;
CURSOR Cursor_B IS
SELECT * FROM EMP_B;
RUNA CHAR(1) := 'Y';
[code]....
I want to avoid maintaining the same long list of transformations. I also want to avoid, if possible, an explicit FETCH INTO, because there are hundreds of fields in both tables. I'm looking for something like this (and I know this doesnt work):
DECLARE
CURSOR Cursor_A IS
SELECT * FROM EMP_A;
CURSOR Cursor_B IS
SELECT * FROM EMP_B;
RUNA CHAR(1) := 'Y';
CursorToRun IS REF CURSOR;
[code]....

create or replace PROCEDURE newprocedur(outname OUT VARCHAR2,outroll OUT NUMBER) AS
CURSOR c1 IS
select Name,Rollno,Section from emp;
BEGIN
Open c1;
fetch c1 into outname,outroll;
Here out of 3 columns in cursor is it possible to fetch only two columns using FETCH like i did above?

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);

ORA-24374: define not done before fetch or execute and fetch
My master-detail form has single canvas. For both blocks, master and detail, two tables joined together in each. One table to be updated, second table has some info for reference (query only).
I am getting these errors when in detail block the item from LOV is selected for existing record. This does not happen for new record inserted in detail block.

I need to calculate OT hour from this two field and store into a third one column. But i'm confuse what should be the data type of the third column. Is it number or else ?
I know difference of two date column is number. So, first i need to know that data type i should use ?
Secondly, how i get the sum of the all stored time ? for example data are
1.30 -- One hour and thirty min.

I found this query in one of my stored procedures that updates a key for a value in a data table by reading the information from a master table.
The data table is: ITEM_INVENTORY
The master table is: MASTER_SOURCE_SYSTEM
UPDATE ITEM_INVENTORY I
SET I.SOURCE_SYSTEM_ID =
(SELECT NVL(M.SRC_SYS_ID,-100)
FROM MASTER_SOURCE_SYSTEM M
WHERE M.SRC_SYS_DESC(+) = I.SOURCE_SYSTEM_CODE )
WHERE ORG_CODE = 'TNXC'
AND EXISTS (SELECT 1 FROM MASTER_SOURCE_SYSTEM M
WHERE M.SRC_SYS_DESC(+) = I.SOURCE_SYSTEM_CODE )
The situation here is that:
1. There are about 15000 rows that match ORG_CODE = 'TNXC'.
2. The SOURCE_SYSTEM_CODE is same for all the 15000 rows and there is a matching entry for it in the MASTER_SOURCE_SYSTEM table.
My question is: Do both the inner select statements execute 15000 times?
The statement executes within a second and updates 15000 rows. How is this made possible?

How to get rows N times in a result set?
For obscure test purposes I need to modify an existing SQL query to emit the rows N times instead once. I'm aware of the possibility to "UNION ALL" the query with itself to get the all rows twice.
But as I require the resulting rows to be emitted around ten to hundred times this approach doesn't seem sensible to me. Not to speak of the missing possibility to parametrize the number of "repetitions".

I am dealing with a bunch of tables containing sales information for an New Zealand organisation. The sale datetime has been recorded as UTC.
New Zealand operates Daylight Savings, so twice a year it changes its clocks.
When New Zealand is on standard time it is UTC+12.
When New Zealand is on daylight savings time it is UTC+13.
Thus an event which actually occurred when New Zealand was on standard time at 2011-08-31 15:20:52 local time, is recorded in the database as having occurred at 2011-08-31 03:20:52. However, an event that actually occurred when New Zealand was on daylight savings time at 2011-10-06 15:20:52 local time, is recorded in the database as having occurred at 2011-10-06 02:20:52.
I want to be able to read the sales dates from my table and convert them to the actual time in New Zealand when the event occurred. The table will contain data for sales that occurred in both standard and daylight savings times.
I do not think that the data has been stored with time zone information, simply that the application writing the data to the Oracle database, calculated the event time as UTC when it occurred and wrote that time to the table.
Does Oracle only know about what UTC-offset is in force right now or is it capable of determining what offset from UTC is required for any given historical date ?

I have code that creates a sequence and a select statement that generates the next number in a sequence. It starts the sequence at 5 and every subsequent number is the previous number minus 3. The minimum value it can go to is 0. All I want is for my select statement to execute three times in a row. Is there any way I can do that?
create sequence MY_FIRST_SEQ
increment by -3
maxvalue 5
start with 5
minvalue 0
nocycle;
select MY_FIRST_SEQ.NEXTVAL from dual;

I would the query to do the following:
1. Make the jobname distinct, because it keeps giving me multiple entries for each jobname
2. Add the the start_time of SOD_start_data9_UAT1 to end_time fodba_MUAT1 to get the combined duration
3. CONCAT jobnames SOD_start_data9_UAT1 and end_time fodba_MUAT1
4. Generate the last seven days batch run times
5. Generate a report into .csv format and email out
6. I have access to sqlplus and plsql developer
select distinct JOBNAME, schedtab
, to_char(to_timestamp(trim(timestmp)

I am trying to determine the number of times a value appears and display the count. However the value can only be counted once per 'trip' even though it may appear several times per trip.
for e.g.
Quote:trip table
-------
trip_id start_date end_date duration
445 01-jan-12 03-jan-12 3
Quote:pickup table
--------
pickup_id trip_id company
1 445 randomname
2 445 randomname
3 445 google.inc
4 878 randomname
with the above data the expected value would be two because the trip id appears twice so it was just the one trip - given a count of one. I am not sure how create a query to check this.
