Because it is explicitly indicated by the source code.
-extraction of the last line.
-display the family name.
-East of expressions of folklore for the whole of the cursor? No - the fact ' pointer' cursor still refers to a valid line
-loop iterates again
-Retrieves the next line - does not exist, then the cursor of the folklore about
-display the family name. Once again.
-East of expressions of folklore for the whole of the cursor? Yes - put end loop

Cursor does not properly... Gives entry each record last records.
Hi all.
a simple for someone, I'm sure...
I've just added the cursor:
-- ***************************************************
-The cursor for Oracle_Loc_Code de SU CHRIS vs ORACLE table locations in a variable...
-- ***************************************************
CURSOR csr_ora_loc_code IS
SELECT sil. ORACLE_LOC_CODE

WHERE STDS. STD_LOCATION_ID = sil. CHRIS_LOC_code;
.. the script I paste below in order to complete each record with what in LIS. Field ORACLE_LOC_CODE.
But, although it works fine when you have 1 card to run at, where several records need to be loaded together, the script, well between records in ORACLE thin, fills all records with the same store code - whatevers in the last record (instead of dealing with each of them individually). How can I fix?
Thanks for looking...

Cursor Oracle return only the last record
I am a newbie in oracle stored proc. I tried to select data using the slider, but it only return last record. The recording must be greater than 1.
CREATE or REPLACE procedure MySchema.Test (myrefcur on sys_refcursor)
Is
Begin
declare
Cursor C1 IS
Select mySerialNum from TableA;
MyRecord C1% rowtype;
Begin
Open C1;
Loop
Fetch C1 into myrecord;
When the output C1% NotFound;
Open for Myrefcur
Select SerialNumB from TableB where SerialNumB = myrecord.mySerialNum;
End loop;
Close C1;
End;
end;
However, it only returns the last record in the list.
Original case *.
The original code is as below:
1st, I'll need to select a list of ImageSerialNum of ImageSerial
* 1 query:
Select A.ImageSerialNum from ImageSerial A, ProductionOrder B, Bom C
Where A.ProductionOrderID = B.ProductionOrderID And B.Assembly_Num = C.Model_Num and
B.Revision = C.Revision And B.EngRevision = C.EngRevision and
C.Bom_ID = passInVariable* and C.FactoryID = "7"
2nd, I'll need to check the process of EACH series with the code below:
* Low code a return process for 1 series only.
Select t.processid, t.processname, t.assembly_num, t.revision, t.engrevision of
(Select p.ProcessID, p.ProcessName, in. Assembly_Num, in. review, in. EngRevision, im.imageserialnum
Process p, Routesequence rs, Imageserial im, ProductionOrder in.
Where im. ImageserialNum = SerialNum* and p.ProcessID = rs. ProcessID
And rs. RouteID = in. RouteID and rs. SequenceID = im. NextRouteSequence
And in. ProductionOrderID = im. ProductionOrderID AND IM. STATUS OF '0'
UNION
SELECT A.REWORKROUTEID AS PROCESSID PROCESSNAME AS B.ROUTENAME, C.ASSEMBLY_NUM, C.REVISION, C.ENGREVISION, a.imageserialnum
OF IMAGESERIAL A, B OF ROAD, PRODUCTIONORDER C
WHERE A.REWORKROUTEID = B.ROUTEID AND A.IMAGESERIALNUM = SerialNum*.
AND A.PRODUCTIONORDERID = C.PRODUCTIONORDERID and a.status = '0') t
After that, I would like to combine the two in 1 stored proc code.in this case, you just want to join the two applications to use in the FROM clause

Properties of the file - Date of the last recorded
Hello.
I'm having trouble understanding the properties of the file, as "Last record Date" (DLS) and "Date modified" (MD).
I asked that the last of them, MD, has been changed whenever the content has changed. But Distribution lists must be updated also.
However, I have a file which has the DLS on 2007 and MD 2014 and the 'last impression"also is 2014.
How is that possible?
What has changed the date the content of the file was really the last?
I would be grateful if someone could help me understand this.
Thank you,
Nuno Roque
Modification date is when the file got changed on that hard drive. Even if you have never opened the file, just drag-and - drop it to drive flash (for an example) would last updated date change, because the file on this disk changed really.
Properties such as "Date of last recorded" and "date printed" are stored in the file itself, such as metadata and are updated no not by disk or operating system, but by the design (such as Word) program.

How to find the last record of the extracted records
Dear members,
I have an OFA Page in which I view record master detail. For each master record can one or more detail records.
In the page I got the button NEXT. If the user clicks the next button, I'm populating the next record of the master and its corresponding detail records.
To achieve this, I wrote the code below in AM:_
Public Sub findNextRec()
*{*
String headerID = null;
Rank rank is getMaster_VO1 () .next ();.
if(Row!=null)
*{*
headerID = row.getAttribute ("HeaderId") m:System.NET.SocketAddress.ToString ();
getDetail_VO1 (.setMaxFetchSize(-1));
getDetail_VO1 () .setWhereClause (null);
getDetail_VO1 () .addWhereClause ("header_id in (: 1)" ");
getDetail_VO1 () .setWhereClauseParams (null);
getDetail_VO1 (.setWhereClauseParam(0,headerID));
getDetail_VO1 () .executeQuery ();
*}*
*}*
My CO code in processFormRequest method is as follows:_
If (PageContext.GetParameter ("Next")! = null)
*{*
am.invokeMethod ("findNextRec");
*}*
Here my requirement is that if it's a last drive, I want to show the user a message saying it's last recording. To achieve this please let me know what the code should be written.
Thanks in advance.
Best regards
Arun D. ReddyArun,
If my interpretation is correct, then you can achieve the same thing by making some minor changes to your existing code.
public void findNextRec() { String headerID=null; Row row = getMaster_VO1().next(); if(row!=null) //your code will return null when if there is no record { headerID=row.getAttribute("HeaderId").toString(); getDetail_VO1().setMaxFetchSize(-1); getDetail_VO1().setWhereClause(null); getDetail_VO1().addWhereClause("header_id in (:1)"); getDetail_VO1().setWhereClauseParams(null); getDetail_VO1().setWhereClauseParam(0,headerID); getDetail_VO1().executeQuery(); } else{ //write down the message that there exist no more rows (custom message) } }Kind regards

How to find inserted last record in the table 'manufacturing '.Not possible as your data model do not answer for him. As simple as that.
If there is a need to determine an order or associate some time to an entity, then that should be part of the data model - and a relationship, or one or several attributes are necessary to represent this information. Your data model in this case is therefore unable to meet your requirements.
If the requirements are valid, set the data model. In other words - your question has nothing to do with Oracle and nothing to do with the other pseudo columns in Oracle, the rowscn or the rowid. It is a question of pure data modeling. Nothing more.

WITH got_rnum AS ( SELECT ename -- or whatever columns you want , RANK () OVER (ORDER BY empno DESC) AS rnum FROM emp ) SELECT * -- or list all columns except rnum FROM got_rnum WHERE rnum = 2 ;For your specific problem, another way may be a bit simpler, but only a little.
I suggest you to master this technique first, because it can very easily be extended to cover the problems associated with, such as "who has the 2nd empno higher in each Department? -
Insert correctly last record to the child table in the multi user environment.
Hello
I have the following situation.
Two Tables
Table1 has a primary key named ID column
Tabel2 contains a column named table1_id, this is a foreign key to table1.
I have a tabular report that contains an add record button and a button submit to table1. (this table has other columns that require attribution)
I want to insert a record into table2 automatically whenever the user presses submit.
I have a query like this to get the last record in table1:
and I would use it in a submit after procedure like this:SELECT MAX(id) FROM table1
The thing that worries me, is that the application that I use is a multi user environment. I'm afraid that if two or more people use as MAX recording is not the right one.DECLARE v_id NUMBER; BEGIN SELECT MAX(id) INTO v_id FROM table1 INSERT INTO table2(table1_id) VALUES (v_id); END;
It's a legitimate concern?
If so, is there a best way to do this kind of thing.Ben:
The triggers are usually avoidable IMO. But, there is always a but, you already use triggers elsewhere in your application, and probably your form the apex uses the routines of APEX MRU for DML and thus leaves the trigger as the only viable option to achieve what you're trying to do.

calculation of ratios and rounding - how the sum of last record to give 1
I'm putting in a single query to calculate the reports for an unknown number of records. I want to turn the ratios to 5 decimal places and I want the total reports of equal to 1.
for example
If I have 3 folders with Qty total overal 4,5,6 is 15
I note 3 lines
Round (4/15.5),
Round (5/15.5),
Round (6/15.5)
but I want to ensure total = 1
so I will try to do something like
Round (4/15.5),
Round (5/15.5),
1 - round(4/15,5) - round(5/15,5)
can someone help show me the sql construction? I've been trying and failing using where clause
of course this example would add to 1 but other unknown ratios may not match up to 1.
Published by: user12154024 on November 2, 2009 22:32Hello 12154024,
Welcome to the forum. May not be a more elegant solution, but it shows how it works step by step
WITH t AS ( SELECT 4 n FROM dual UNION ALL SELECT 5 n FROM dual UNION ALL SELECT 6 n FROM dual ) ,t1 AS ( SELECT n ,ROUND(RATIO_TO_REPORT(n) OVER (),5) AS rr ,COUNT(n) OVER () AS c ,ROW_NUMBER() OVER (ORDER BY n) AS rn FROM t ) ,t2 AS ( SELECT n ,rr ,SUM(rr) OVER (ORDER BY n) s ,c ,rn FROM t1 ) SELECT n ,rr ,CASE WHEN c = rn THEN rr + (1 - s) ELSE rr END rr2 ,s FROM t2 ORDER BY rn; N RR RR2 S --- --------- --------- -------- 4 0.26667 0.26667 0.26667 5 0.33333 0.33333 0.6 6 0.4 0.4 1 3 rows selectedThe part "WITH t AS" generates data
T1 calculate the ratio, counts the number of records and signs a current issue
T2 to calculate a cumulative ratio
the last part takes these data and for the last record (number = count running) it allows to adjust the ratio.You can see if you are using other data
WITH t AS ( SELECT 4.78 n FROM dual UNION ALL SELECT 5 n FROM dual UNION ALL SELECT 6 n FROM dual ) ... N RR RR2 S ---- -------- -------- -------- 4.78 0.30292 0.30292 0.30292 5 0.31686 0.31686 0.61978 6 0.38023 0.38022 1.00001 3 rows selectedConcerning

What is the best way to get the last record in a table?
... in addition to select * from tbl by id Desc... & then set = 1 maxrow in cfoutput.
I want a quick way.
I tried "Max (id), columns, but not worked.
If I ' Max (id) as V ' & then turn around and make another request for ' where id = #V # "to get the rest of the record, there's more action.

From your_table)Phil
