TIPS(64) : ORDERING 된 상위 "N" ROWS 만 RETRIEVE 하는 SQL문
제품 : SQL*PLUS
작성날짜 : 2002-12-20
ORDERING 된 상위 "N" ROWS 만 RETRIEVE 하는 SQL문
===============================================
PURPOSE
다음은 특정 Column 으로 Ordering 된 상위 "n" rows 만 Return 하기 위한
간단한 SQL 문을 소개한다.
Explanation
Example
SELECT *
FROM table A
WHERE n >= (SELECT COUNT(*)
FROM table B
WHERE B.column >= A.column)
ORDER BY column DESC;
예) Emp Table 에서 Salary 가 많은 상위 5명만 구하는 SQL 문
SQL> select empno,ename,sal
2 from emp A
3 where 5 >= (select count(*)
4 from emp B
5 where B.sal >= A.sal)
6 order by sal desc
7 /
EMPNO ENAME SAL
7839 KING 5000
7788 SCOTT 3000
7902 FORD 3000
7566 JONES 2975
7698 BLAKE 2850
5 rows selected.
->Oracle 8i 이상인 경우
다음과 같이 간단히 query 할수 있다.
1 select empno,ename,sal
2 from (select * from emp order by sal desc)
3* where rownum <= 5;
위의 예는 상위 "n" Rows 만 정확히 Return 한다. 그러나 중복된
Column Value 를 가진다면 다음의 예를 고려해 보아야 할 것이다.
SELECT *
FROM table A
WHERE n >= (SELECT COUNT(DISTINCT column)
FROM column B
WHERE B.column >= A.column)
ORDER BY column DESC;
예)
SQL> select empno,ename,sal
2 from emp A
3 where 5 >= (select count(distinct sal)
4 from emp B
5 where B.sal >= A.sal)
6 order by sal desc
7 /
EMPNO ENAME SAL
7839 KING 5000
7788 SCOTT 3000
7902 FORD 3000
7566 JONES 2975

Order of rows retrieved from collection
hi -- If I do not specify an ORDER BY clause when selecting rows from a collection, is
there any pre-defined order in which they'll be returned? (Eg perhaps in the order each
row is added to the collection...)
I ask because I've been using a particular collection for ages, but forgot to specify
an order when querying from it. Just today it returned the rows in a different order
than it has in the past -- only once -- and then they were returned as before.
The order I want -- and have been getting -- is the order in which they're added to the collection.
Will the 'no query transformation' hint accomplish this, or do I need a member that specifies the order?
Thanks,
CNever mind... got it.

How to execute procedure returning data rows from sql plus
Hi,
I want to execute a stored procedure that returns data rows from sql plus. please let me know the syntax for the same.
Thanks,
YGuser13065317 wrote:
Even if i get the result set into the cursor, do i have to do normal fetch into all the coumn variables within a loop
But suppose no of columns in my result set varies depending on a parameter to the stored procedure.
Is there any straightforward way to retrieve all the data irrespective of no of columns in the result set.There is no such thing as a "+result set+". Oracle does not create a temporary data set in memory that contains the results of your query. What would happen if this result set is a million rows and is too large to fit into memory? Or there are a 100 clients each with a 100,000 row result set?
This is not scalable. You will be severely limited in the number and sizes of these "+result sets+" that can be created in server memory.
A cursor is in fact a "program" that is created by compiling the SQL source code that you provide. This source code is parsed and compiled into what Oracle calls an execution plan. This is nothing but a series of instructions that the cursor will execute in order to return the rows required.
Thus the result set is actually the output from a cursor (a program). Likewise, bind variables are the input parameters to this program.
All SQLs are parsed and compiled as cursors and stored in the SQL Shared Pool. Oracle gives you handle in return to use to address this cursor - bind values to it, execute it, describe the output structure returned by the cursor, and fetch the output from the cursor.
On the client side, this handle is used in different ways. In PL/SQL alone, this cursor handle can be used as an implicit cursor (you do not even see or use the cursor handle in your PL/SQL code). Or you can use a PL/SQL cursor variable. Or a DBMS_SQL cursor variable. Or a reference cursor variable.
Why so many different client structures for the very same SQL cursor handle returned by Oracle? Because to allow you, the programmer, all kinds of different features and flexibility.
The ref cursor feature is the ability to pass this cursor handle around, not only between PL/SQL code, but also from PL/SQL to the actual client process (Java. VB, SQL*Plus, TOAD, etc).
The primary thing to remember - irrespective of what the client calls this (e.g. ref cursor, SQL statement handle, etc), this all refers to the same SQL cursor in the Shared Pool. And that this SQL cursor is a program that outputs data, and not a result set in itself. -
How to preset the order of rows in the outer query of a correlated query ?
Good morning,
I have the following simple query:
select empno,
ename,
sal,
sum(case
when rn = 1 then sal
else -sal
end) over (order by sal, empno) as running_diff
from (
select empno,
ename,
sal,
row_number() over (order by sal, empno) as rn
from emp
where deptno = 10
);That calculates a running difference and uses "row_number() over (...)" which is an Oracle specific feature to do so. It yields the following result (which we will consider correct):
EMPNO ENAME SAL RUNNING_DIFF
7934 MILLER 1300 1300
7782 CLARK 2450 -1150
7839 KING 5000 -6150I wanted to come up with a solution that was not Oracle specific different solution. I tried the following code:
(EDIT: after additional thought, that code is totally different in meaning and will never come close, to the above result. Consider it wrong and ignore this attempt altogether.)
select a.empno,
a.ename,
a.sal,
(select case
when a.empno = min(b.empno) then sum(b.sal)
else sum(-b.sal)
end
from emp b
where b.empno <= a.empno
and b.deptno = a.deptno) as running_diff
from emp a
where a.deptno = 10;but the result is
EMPNO ENAME SAL RUNNING_DIFF
7782 CLARK 2450 2450
7839 KING 5000 -7450
7934 MILLER 1300 -8750which is a long way from the original result. I've tried everything I could think of to order the rows before the running difference is calculated but, have been unsuccessful.
Is there a way to change this second query --(without using Oracle specific features)-- without using windowing features that would yield the same result as the first query ?
Rephrase of the above question:
Is there a way, using plain vanilla SQL (that is aggregate functions and set operations such as joins and unions) to create a query that yields the same result as the first one ?
Also, this is not for production code. This is simply an exercise in set manipulation that I'd like to see a solution for.
Thank you for your help,
John.

Edited by: 440bx - 11gR2 on Jul 18, 2010 3:51 AM - Noted that my try is woefully wrong and restated the objective to make it clearer.Hi, John,
One way to get a running total (which is basically what you want) is to do a self-join. Join each row (let's call it the current row, or c) to itself and everything that came before it (let's call this the previous row, or p), and do a regular aggregate SUM, like this:
WITH got_base_sal AS
SELECT deptno
, 2 * MIN (sal) AS base_sal
FROM scott.emp
GROUP BY deptno
SELECT c.deptno
, c.empno
, c.ename
, c.sal
, b.base_sal - SUM (p.sal) AS running_diff
FROM scott.emp c
JOIN scott.emp p ON c.deptno = p.deptno
AND ( c.sal > p.sal
OR ( c.sal = p.sal
AND c.empno >= p.empno
JOIN got_base_sal b ON c.deptno = b.deptno
WHERE c.deptno IN (10)
GROUP BY c.deptno
, c.empno
, c.ename
, c.sal
, b.base_sal
ORDER BY c.deptno
, running_diff DESC
;Output:
DEPTNO EMPNO ENAME SAL RUNNING_DIFF
10 7934 MILLER 1300 1300
10 7782 CLARK 2450 -1150
10 7839 KING 5000 -6150I said you basically want a runninng total. There are two differences between a running total and your requirements
(1) You want to have a total of the negative of what's in the table. That's trivial: use a minus sign.
(2) You want the first item to count as positive instead of negative. That's not so trivial. The query above counts all sals as negative, but adds an offset so that it appears as if the first item had been counted as positive, not negative.
You didn't say what you want to do in case of a tie (two or more rows having the same sal). The query above uses empno as a tie-breaker, so that all sals are calculated as if they were distinct. This is similar to what analytic functions do when the windowing is based on rows. If you want something similar to windowing by range, that might actually be simpler.
The query above calculates a separate running_diff for each deptno, similar to "PARTITION BY deptno" in analytic functions. You happen to be interested in only one deptno right now, but you can change the main query's WHERE clause, or omit it, and the query will still work. If you don't want this feature (analagoud to not having any PARTITION BY), it's easy to modify the query.
You could also get these results using a recursive WITH clause. That meets the criteria of avoiding analytic functions and Oracle-specific features, but not the one about using only plain, simple SQL features. -
Alert about the loading time & Restrict the number of the rows retrieved
Hi everybody, maybe the question is stupid, but I didn't find yet an answer...
I'm using BIP 10.1.3.4.1
Because I have many reports with a huge amount of data to display (in HTML format) and customers once clicked on "View" have to wait a lot of time, they asked me if there is the possibility to do the following things:
1. restrict the number of the rows retrieved (this for each report); this request has to be dynamic (different rows' number for each report and for each user); so, I can't modify the query into the data template in order to retrieve a fixed number of rows;
2. show an alert who says for example " The data loading will take 5 minutes. Do you want to proceed ? YES - NO" This to inform the users how much time they have to wait if they click on Yes.
I checked under the Administrator TAB...but I didn't find nothing "native" about the two questions above.....
So, I ask you if there is a way to activate these features (if they exist "native") or a workaround to implement what I described above.
Any help will be appreciated.
Thanks in advance
AlexHi Vetsrini, thanks for your answer.....but what does it mean ? There are no solutions for my requests ? I remember that Discoverer had the possibility to have an alert as I would like to have with BI Publisher and there was the possibility to choose how many rows it was required from the customer....Is it possible that with BIP is not applicable ?
Have a good day

How to get rank within the row in SQL
I have an a key orderid and 4 other columns with orderdate&time in (16/12/2011 16:15:24 format) within a table.
the orderid has an average of 1million rows every week hence could not do this in excel for a 15 day period .
ORderid.........: mail........................................ : telephone ............................:online ........................................ store.......................... Agency
A3456...........15/12/2011 16:15:24 ............... 16/12/2011 14:12:01.............16/12/2011 16:14:00..........17/12/2011 11:22:55 ............12/12/2011 22:20:30
B678
C555
i want to create a new table which ranks each row according to the max orderdate and time say in another table
i want to capture the rank
KEY.......Mail............Tel............online.........store..........Agency
A3456.....4 ...............3...............2...............1............... 5
Is there any way either within the same table or in other table i wiould be able to get the rank based on the rows in SQL.
thnks
Edited by: UOOLK on 29-Dec-2011 06:46Something like this I think:
create new_order_table as
select order_id
,rank() over (order by mail desc) mail
,rank() over (order by telephone desc) telephone
,rank() over (order by online desc) online
,rank() over (order by store desc) store
,rank() over (order by agency desc) agency
from old_order_table;Assuming you want the most recent date to be ranked number 1. If you want number 1 to be the oldest then remove all the 'desc's from the order by clauses. -
Ordering datagrid rows by dragging rows
Hi all,
I have a normal dg which is pulling data from MySQL db and
i'm trying
to figure out the best way to allow users to drag the rows to
re-order
as per however they may want it..
This is what I thought buy some feedback would be great!
1. Add 'order' column to sql db
2. Set inital order for each row
3. sort by order desc when pulling db into dg
4. Create function to:
a. when a user drops a row into desired position make each
rows
order = each rows index
b. update mysql db when all changes are complete
I also thought, maybe remember oldOrder val, + 1 to each
order value
from point of insertion until order = oldOrder??
Obviously this method has issues when the # of rows grows..
so thats
why I would love some help with this! there must be a better
way :)
Thanks in advance!

Combining multiple rows to singe row thru SQL Stmt
Hello,
I am trying to combine values returned from multiple row into one row,
thru inner/outer sql or any optimal way.
In the example i would like to have First name, Last name, email and phone to be
returned as a single row.
create table TEMP_AAAAA
FIRST_NAME VARCHAR2(25),
LAST_NAME VARCHAR2(25),
CON_METHOD VARCHAR2(25),
CON_VALUE VARCHAR2(25)
INSERT INTO TEMP_AAAAA VALUES('TOM','MAC','EMAIL','[email protected]');
INSERT INTO TEMP_AAAAA VALUES('TOM','MAC','PHONE','12345');Any suggestion in doing it thru sql stmt.
I have done this thru pl/sql, wondering if this could be achieve thru single SQL Stmt
DECLARE
v_FIRST_NAME VARCHAR2(25);
v_SECOND_NAME VARCHAR2(25);
v_EMAIL VARCHAR2(25);
v_PHONE VARCHAR2(25);
BEGIN
v_FIRST_NAME := NULL;
v_SECOND_NAME := NULL;
v_EMAIL := NULL;
v_PHONE := NULL;
FOR IMPL_CUR IN(SELECT * FROM TEMP_AAAAA ORDER BY CON_METHOD DESC)
LOOP
IF v_FIRST_NAME IS NULL
THEN
v_FIRST_NAME := IMPL_CUR.FIRST_NAME;
END IF;
IF v_SECOND_NAME IS NULL
THEN
v_SECOND_NAME := IMPL_CUR.LAST_NAME;
END IF;
IF v_PHONE IS NULL AND IMPL_CUR.CON_METHOD = 'PHONE'
THEN
v_PHONE := IMPL_CUR.CON_VALUE;
END IF;
IF v_FIRST_NAME = IMPL_CUR.FIRST_NAME AND
v_SECOND_NAME = IMPL_CUR.LAST_NAME AND
length(v_PHONE) > 0
THEN
IF v_EMAIL IS NULL AND IMPL_CUR.CON_METHOD = 'EMAIL'
THEN
v_EMAIL := IMPL_CUR.CON_VALUE;
EXIT;
END IF;
END IF;
END LOOP;
DBMS_OUTPUT.put_line('firstName...:' || v_FIRST_NAME);
DBMS_OUTPUT.put_line('lastName....:' || v_SECOND_NAME);
DBMS_OUTPUT.put_line('PHONE.......:' || v_PHONE);
DBMS_OUTPUT.put_line('EMAIL.......:' || v_EMAIL);
END;Hi Ludy,
Following query should work -
P.S. - I have added records for one more person with first name as 'TOM1' and last name as 'MAC1' for testing purpose. Given inserts for these 2 records as well.
Connected to Oracle Database 11g Release 11.2.0.1.0
SQL>
SQL> INSERT INTO TEMP_AAAAA VALUES('TOM1','MAC1','EMAIL','[email protected]');
1 row inserted
SQL> INSERT INTO TEMP_AAAAA VALUES('TOM1','MAC1','PHONE','12345');
1 row inserted
SQL>
SQL>
SQL> SELECT t.first_name
2 ,t.last_name
3 ,MAX(decode(t.con_method, 'PHONE', t.con_value, NULL)) phone
4 ,MAX(decode(t.con_method, 'EMAIL', t.con_value, NULL)) email
5 FROM temp_aaaaa t
6 GROUP BY t.first_name
7 ,t.last_name
8 /
FIRST_NAME LAST_NAME PHONE EMAIL
TOM MAC 12345 [email protected]

How to get the last transaction in a row in SQL Developer?
What syntax would I use to get the last transaction of a row in SQL developer?
The way I have my query set-up currently it is not returning the correct data, here is my current syntax:
select ssn, max(tran_id), chng_type,tran_id
from pda_tran
where ssn = 'xxx-xxx-0011'
and chng_type = 'C'
group by ssn, chng_type,tran_id;
It returns a 'C' chng_type but it is not the last one. when I query on this ssn this is what I get:
ssn tran_id chng_type
xxx-xxx-0011 001 A
xxx-xxx-0011 002 E
xxx-xxx-0011 003 C
xxx-xxx-0011 004 S
xxx-xxx-0011 005 C
xxx-xxx-0011 006 T
I only want to return the ssn's with a last transaction chng_type of 'C'. How can I get the correct information returned. Please advise.From what I see and read... there is one to many group by
You wrote
select ssn, max(tran_id), chng_type,tran_id
from pda_tran
where ssn = 'xxx-xxx-0011'
and chng_type = 'C'
group by ssn, chng_type,tran_id;
If you want the max(tran_id), remove it from the "group by"
select ssn, chng_type, max(tran_id)
FROM
(SELECT 'xxx-xxx-0011' ssn, '001' tran_id, 'A' chng_type FROM DUAL UNION

where can we look into for this issue? actually we need rows will be the same ordering as it was in 9i.
we are facing this problem in lot of queries, this is a sample one.
Regards
HalimHi Jgarry,
why do you need a particular physical order?
Actually i don't know the .net application behave or code yet . but after migration, I am facing this issue.
one more thing we changed the server machine so Is there any registry parameter (in windows) related to this. Have you any idea.
the application is running since 8 years and I think nobody can rely on implicit data distribution arising from how the data is entered to develop a application.
Hi Hoek,
According to Oracle White Paper(page 17), If I change below parameter. Is there any hope to get same order.
"After you upgrade to Oracle Database 10g, if you
wanted to revert back to 9.2 optimizer behavior you can set
OPTIMIZER_FEATURES_ENABLE = 9.2.0 "
Regards

Restricting users ability to modified Max Rows Retrieved
Hi
In Web Intelligence Rich Client how can I restrict a users ability to change the Max Rows Retrieved in a query.
Currently we use Desktop Intelligence and restrict max rows retrieved in the universe, but I note this can be overwritten when by the user in Webi Rich Client at the query creation stage.
SAP documentation indicates that a restriction can be applied in the security profile via the CMC but I'm unable to find this.
Any help would be appreciated.
Cheers
SeanAny info would be helpful at this stage. Thanks

How to retrieve SQL statement in the CR 2008
I'm using Crystal Reports 2008 in MS Visual Studio 2008, how can i retrieve SQL statement from *.rpt file, i have tried this code, but it doesn't work:
ReportDocument rdReport = new ReportDocument();
rdReport.Load("Reports/EmployeeTest.rpt", OpenReportMethod.OpenReportByTempCopy);
CrystalDecisions.ReportAppServer.Controllers.RowsetController rsController;
CrystalDecisions.ReportAppServer.ClientDoc.ISCDReportClientDocument rdClient = rdReport.ReportClientDocument; // on this line it throws an exception "The ReportClientDocument property can only be accessed when the report is opened using a Report Application Server."
CrystalDecisions.ReportAppServer.DataDefModel.ISCRGroupPath rdGroupPath = new CrystalDecisions.ReportAppServer.DataDefModel.GroupPath();
string temp;
string sql;
rsController = rdClient.RowsetController;
sql = rsController.GetSQLStatement(rdGroupPath, out temp);
maybe i'm doing something wrong ?
thanksHello Ludek,
when I try to get the report from the session I got an error like this (I am using State Server Session mode i.e out proc in my application)
ReportClientDocument 'reportDocument.ReportClientDocument' threw an exception of type 'System.InvalidOperationException' CrystalDecisions.ReportAppServer.ClientDoc.ISCDReportClientDocument {System.InvalidOperationException}
+base {"The ReportClientDocument property can only be accessed when the report is opened using a Report Application Server."} System.SystemException {System.InvalidOperationException}
StackTrace " at CrystalDecisions.CrystalReports.Engine.ReportDocument.get_ReportClientDocument()" string
so is it the problem of not opened with RAS. Does installation of RAS solves the problem, If so Is it a free-ware or needs to be purchased.

Unknown Database Connector Error Details: "Failed to retrieve SQL Error"
Hi
Getting "Failed to retrieve SQL Error" while trying to refresh the Crystal report.
Unable to create a new report also
This is my ERROR MESSAGE
"Unknown Database Connector Error Details: "Failed to retrieve SQL Error"
Previous Error: Query generated multiple SQL statements.However multiple SQL is not supported in crystal reports query panel"
Any Suggestion.Hi,
Please note that any query that generates multiple SQL statements is not supported in the Query Panel in Crystal Reports.
I guess this Universe is generating multiple SQLs and hence the error.
I found this option while I was searching for something else: Could you try turning off the "Multiple SQL statement for each measure" in the Universe parameters and see if it works?
Also, here's the Universe Support Guide, although old, it is still applicable:
