How this query executing internally

Dear All,
This query picks the nth highest paid employee details, we can acheive this by rank or desnse_rank functions also
But those execution is easily understandable.But Iam not able to understand , how this below correlated subquery executing internally .Please help me on this query
select * from emp a where &n=(select count(distinnct b.sal) from emp b where a.sal<=b.sal)
Thanks in advance

How this procedure works INTERNALLY???

HI Experts
I have created the below procedure(It is updating 50 million records in decent time) but I have few doubts.
1) I am not commiting till the end. Will it take up the UNDO space. How can I assure that this procedure executes till the end.
2) If i have to increase the UNDO space how should I increase considering 50 million rows.
3) Do I have to consider factors other than UNDO space while running this procedure if yes then wat are they.
4) Suggest me some links where i can find out how sql queries and pl/sql objects works internally.

Remember that besides UNDO you also have to worry about redo !
If you create a new session for every test run at each volume level, you can query V$SESSTAT for the statistiic 'redo size' so as to identify the Bytes of Redo for each volume level. And then extrapolate from there !

Can you please explain how this query is fetching the rows?

here is a query to find the top 3 salaries. But the thing is that i am now able to understand how its working to get the correct data :How the data in the alias table P1 and P2 getting compared. Can you please explain in some steps.
SELECT MIN(P1.SAL) FROM PSAL P1, PSAL P2
WHERE P1.SAL >= P2.SAL
GROUP BY P2.SAL
HAVING COUNT (DISTINCT P1.SAL) <=3 ;
here is the data i used :
SQL> select * from psal;
NAME SAL
able 1000
baker 900
charles 900
delta 800
eddy 700
fred 700
george 700
george 700

Renu

... Please help me in understanding the query.
Your query looks like anything but a Top-N query.
If you run it in steps and analyze the output at the end of each step, then you should be able to understand what it does.

test@ora>
test@ora>This query joins PSAL with itself using a non equi-join. Take each row of PSAL p1 and see how it compares with PSAL p2. You'll see that:
- Row 1 with sal 1000 is >= to all sal values of p2, so it occurs 8 times
- Row 2 with sal 900 is >= to 9 sal values of p2, so it occurs 7 times
- Row 3: 7 times again... and so on.
- So, total no. of rows are: 8 + 7 + 7 + 5 + 4 + 4 + 4 + 4 = 43

How this code execute

class c is an abstract class n the class a extends c. Inside the main method of class a I have a reference to class c n the object of class a. When I execute the print statement it print c that mean method in the abstract class. But I create the object for the concrete class which extends the abstract class. Seems like the object was created for the abstract class. How could that happen. Can some one help me . Thanks in advance.
abstract class c{
     public static void cc(){
          System.out.println("c");
public class a extends c{
     public static void cc(){
          System.out.println("a");
public static void main(String args[]){
     c obj=new a();
     obj.cc();
}

I found the solution for that. That's because static KW. Even I create the object of concrete class the reference is abstract class. Since the method is static that method call. If I remove that sub class method get called.

How this query can be reduced

Hi all,
I have placed some repeating conditions in many places of the query , Please suggest me to reduce the size of the query .

A few days ago, you were already suggested to use the WITH statement.
Did you try using the WITH statement?

[8i] Query with lots of subqueries: a simpler way to do this query?

Ok, so generally, my problem is that I can't figure out how to write this query without including a bunch of copies of the same subquery (similar to having to join multiple copies of a table). Basically, I have to get information that's in rows in one table into columns in the results of my query. I've created sample tables, with insert statements for sample data, and a trimmed-down version of the query I'm running against those (2) tables. I'll explain what I mean by "trimmed-down" where I provide the SQL for that query.
My restrictions:
1) I'm running in 8i
2) I cannot create any tables in the database (I can only do read-only queries and create views).
Here are my sample tables and sample data:
CREATE TABLE     reqs
(     req_id          NUMBER     NOT NULL,
     part_no          VARCHAR2(5),
     req_date     DATE,
     req_qty          NUMBER,
     CONSTRAINT reqs_pk PRIMARY KEY (req_id)
INSERT INTO     reqs
VALUES (1,'part1',To_Date('01/01/2010','mm/dd/yyyy'),5);
INSERT INTO     reqs
VALUES (2,'part2',To_Date('01/10/2010','mm/dd/yyyy'),25);
INSERT INTO     reqs
VALUES (3,'part1',To_Date('01/20/2010','mm/dd/yyyy'),3);
INSERT INTO     reqs
VALUES (4,'part2',To_Date('02/01/2010','mm/dd/yyyy'),15);
INSERT INTO     reqs
VALUES (5,'other',To_Date('02/05/2010','mm/dd/yyyy'),1);
INSERT INTO     reqs
VALUES (6,'part1',To_Date('02/07/2010','mm/dd/yyyy'),10);
INSERT INTO     reqs
VALUES (7,'part3',To_Date('02/25/2010','mm/dd/yyyy'),22);
INSERT INTO     reqs
VALUES (8,'part1',To_Date('03/01/2010','mm/dd/yyyy'),24);
INSERT INTO     reqs
VALUES (9,'part3',To_Date('04/01/2010','mm/dd/yyyy'),12);
CREATE TABLE     part
(     part_no          VARCHAR2(5)     NOT NULL,
     part_desc     VARCHAR2(25),
     qty_instock     NUMBER,
     CONSTRAINT part_pk PRIMARY KEY (part_no)
INSERT INTO     part

INSERT INTO     part

ORDER BY     part.part_noThe sample query above only gets 3 months worth of my tot_req_qty for each part number, which equals 3 (+1 for past due) copies of the subquery. This is how this query is "trimmed down" from my actual query; in my real query, I need to include at least 6 months (up to 12 months) of my tot_req_qty for each part number--which means 6-12 (+1) copies of the subquery...ick. I just can't imagine that being an efficient way to get this done.
Here's a table of the results I expect to get from my sample query:
PART_NO     PART_DESC          QTY_INSTOCK     QTY_PAST_DUE     QTY_THIS_MONTH     QTY_NEXT_MONTH     QTY_MONTH_3
part1     description 1 here     5          8          10          24          0
part2     description 2 here     10          40          0          0          0
part3     description 3 here     0          0          22          0          12Is there anything I can do differently here?
Thanks!!

Hi,
Instead of doing self-joins, you can pivot one result set.
Since it's just one result set, you can use an in-line view for it:
SELECT     part.part_no
,     part.part_desc
,     part.qty_instock
,     SUM ( CASE WHEN m.month_reqd = 'Past Due'
                   THEN m.tot_req_qty
             ELSE      0
           END
         )          AS qty_past_due
,     SUM ( CASE WHEN m.month_reqd = To_Char(sysdate,'MON-yyyy')
                 THEN m.tot_req_qty
             ELSE      0
           END
         )          AS qty_this_month
,     SUM ( CASE WHEN m.month_reqd = To_Char(Add_Months(sysdate, 1),'MON-yyyy')
                 THEN m.tot_req_qty
             ELSE      0
           END
         )          AS qty_next_month
,     SUM ( CASE WHEN m.month_reqd = To_Char(Add_Months(sysdate, 2),'MON-yyyy')
                 THEN m.tot_req_qty
             ELSE      0
           END
         )          AS qty_month_3
FROM     part
,     (     -- Begin in-line view m
          SELECT part_no
          ,       SUM (req_qty)          AS tot_req_qty
          ,     month_reqd
          FROM    (     -- Begin in-line view rd
                    SELECT part_no
                    ,     req_qty
                    ,       CASE
                              WHEN req_date   < sysdate
                                        THEN 'Past Due'
                                        ELSE To_Char(req_date,'MON-yyyy')
                            END          AS month_reqd
                    FROM     reqs
                    WHERE     req_date     < TRUNC ( ADD_MONTHS (SYSDATE, 3)
                                          , 'MONTH'
               ) rd     -- End in-line view rd
          GROUP BY   part_no
          ,          month_reqd
       ) m     -- End in-line view m
WHERE       part.part_no     = m.part_no
GROUP BY part.part_no
,       part.part_desc
,       part.qty_instock
ORDER BY part.part_no
;Notice I used a nested in-line view to compute month_reqd, rather than repeat the CASE expression. That's independent of the pivot: you can do either one with or without the other.
Thanks for posting the CREATE TABLE and INSERT statements!

Need information on this Query

Hi guys,
can someone explain how this query works indetail.
SELECT DISTINCT (a.sal) FROM EMP A WHERE &N = (SELECT COUNT (DISTINCT (b.sal)) FROM EMP B WHERE a.sal<=b.sal);
Advance thanks for your help.

Hi,
SELECT DISTINCT (a.sal),(SELECT COUNT (DISTINCT (b.sal)) FROM EMP B WHERE a.sal<=b.sal) FROM EMP A order by 2 descI hope this will help you.
The query will rank the records as per salary amount. and you will get the salary amount of the specified rank.

I am new to oracle, plz..anybody can explain this query step by step....plz

Select distinct(a.esal) from employee1 a where &N = (select count(distinct(b.esal)) from employee1 b where a.esal<=b.esal);
this is the query to find Nth largest & Nth smallest value from the table employee1....but, i am unable to understand how this query works ....plz..anybody can explain this query step by step with example....plz

Hi,
Welcome to the forum!
The first step in understanding any code is to format it so you can easily see what is a sub-query, what the major clauses of each sub-query are, and things like that.
For example:
Select distinct (a.esal)
from   employee1      a
where &N     = (       select count (distinct (b.esal))
                         from      employee1      b
                where      a.esal           <= b.esal
            );The only thing I have added to the code you posted was whitespace: newlines, tabs and spaces.
Now it's easy to see that you're doing a query with a scalar sub-query in the WHERE clause.
It usually makes sense to read complicated queries from the inside out, that is, start with the deepest nested sub-query.
In this example, that means:
select count (distinct (b.esal))
from     employee1      b
where     a.esal           <= b.esalWhat does this query do? Unfortunately, it references something (b.esal) from the super-query, so you can't run it by itself, to see what it does. Let's replace that reference with some hard-coded value, just for now, and run it:
select count (distinct (b.esal))
from     employee1      b
--where     a.esal           <= b.esal     -- This is the original WHERE clause
where   a.esal           <= 1000     -- For testing only
;Experiment with this for a while, and compare it to the values in the employee1 table (or a small test table that resembles employee1). Try different numbers in place of 1000.
You'll see that the query is counting how many different salaries are lower than, or equal to, a given salary (1000 in the example above).
When you understand the sub-query, look at the original query again.
It is testing to see if exactly &N different esals are lower than or equal to the esal on each row, and displaying that esal if it is. (&N is a substitution variable. If you haven't already defined a value for it, SQL*Plus will ask you for a value when you run the query.)
In other words, it is finding the N-th lowest value of esal.

How can I execute a query from a BSP application?

How can I execute a query from a BSP application?
I´m trying to execute a Query from intranet. I´ve been looking for examples, but the templates I´ve found doesn´t help me.
does anybody has an example?
Thanks.

Hi
Have you designed the BSP application ?
design it first with one page
page will have layout and Event handlers
Design the layout with the fields
in the event handler there are events
in the event On Initiailization or ON inputprocessing write the select query similar to what we write in routine ABAp and fetch the data into ITAB and that has to be passed to the Layout
see the doc
BSP
To learn how to create Web applications with Business Server Pages, you can work through the simple tutorials that build on each other. You should be able to run through all of the steps described here in your own system.
If you want to develop Web applications with BSPs, your system must meet the following requirements: Prerequisites for Creating Web Applications.
The following tutorials are available:
· First Tutorial: First Steps with Business Server Pages
· Second tutorial: A Small BSP Application and A Small BSP Application with HTMLB
· Third tutorial: Our First Online Bookshop
· Fourth tutorial: Further Developing the Bookshop
· A small Tutorial is also available for your first steps with the Model View Controller design pattern.
· For a more complex MVC tutorial based on the third tutorial, see: Our Little Online Bookshop Using MVC and HTMLB
When creating BSP applications, note the browser dependencies described in Note 598860.
steps:
1) start the transaction RZ10.
2) now u u have to select Profile name, so select the INSTANCE Profile from the list of options given with the Profile parameter list.U may find multiple instance profile in the list, so select the profile in which ur server name is given.
3) u will also find three options in the same window.
Administrator data, Basic Maintenance, and Extended Maintenance. So select the last one from that.
4) Now click on change button.
5) here u will find parameter icm/host_name_full, so now set it as FQDN.
6) Now copy ur settings with new version number.
7) Activate that version.
8) And now please restart ur WAS.
So this will set ur FQDN, and also don't forget to login using Admin User.
Now u also check for following service are active in your ICF setting or not,( just start transaction code SICF)

Please help me how to improve the performance of this query further.

Hi All,
Please help me how to improve the performance of this query further.
Thanks.

Hi,
this is not your first SQL tuning request in this community -- you really should learn how to obtain performance diagnostics.
The information you posted is not nearly enough to even start troubleshooting the query -- you haven't specified elapsed time, I/O, or the actual number of rows the query returns.
The only piece of information we have is saying that your query executes within a second. If we believe this, then your query doesn't need tuning. If we don't, then we throw it away
and we're left with nothing.
Start by reading this blog post: Kyle Hailey &raquo; Power of DISPLAY_CURSOR
and applying this knowledge to your case.
Best regards,
Nikolay

How to Improve perfomance of this query

Hi,
Please help me to improve this query performance. Objective of this query is to find out individual count who order the product in last two year and create a matrix with time period
Challenge is Both the table having more than 600 million record so it is taking to much time to execute
SELECT count(unique b.individual_id),
sum((CASE WHEN NVL(ORDER_DT,TO_DATE('05-MAY-1955'))>= SYSDATE - 45 THEN 1 ELSE 0 END )) AS one_month ,
sum((CASE WHEN NVL(ORDER_DT,TO_DATE('05-MAY-1955'))>= SYSDATE - 105 and NVL(ORDER_DT,TO_DATE('05-MAY-1955')) <= SYSDATE - 45 THEN 1 ELSE 0 END )) AS Three_month,
sum((CASE WHEN NVL(ORDER_DT,TO_DATE('05-MAY-1955')) >= SYSDATE - 195 and NVL(ORDER_DT,TO_DATE('05-MAY-1955')) <= SYSDATE - 105 THEN 1 ELSE 0 END )) AS six_month,
sum((CASE WHEN NVL(ORDER_DT,TO_DATE('05-MAY-1955')) >= SYSDATE - 380 and NVL(ORDER_DT,TO_DATE('05-MAY-1955')) <= SYSDATE - 195 THEN 1 ELSE 0 END )) AS one_year,
sum((CASE WHEN NVL(ORDER_DT,TO_DATE('05-MAY-1955')) >= SYSDATE - 745 and NVL(ORDER_DT,TO_DATE('05-MAY-1955'))<= SYSDATE - 380 THEN 1 ELSE 0 END )) AS two_year
from ORDER b, address a
where b.individual_id = a.individual_id
and a.COUNTRY_CD ='US'
group by a.COUNTRY_CD ;
Thanks

Challenge is Both the table having more than 600 million record so it is taking to much time to execute Dombrooks has provided you with an excellent response.
In addition, you should mention how much time the query is currently taking and how much do you expect it to take, what is your database version etc.
One of the most important thing is to post your SQLs and EXPLAIN PLAN outcomes in readable format. You can do this by wrapping it within \ and \ tags.
Now, based on the limited details that you have provided, following are my questions/observations:
a) You claim that both tables have more than 600 million rows but your plan shows that optimizer is expecting to find only 46 million rows in ORDER table. You may want to confirm if statistics on both the tables are correct.
b) Your plan appears to suggest that the UNIQUE is not affecting the query results. Based on your knowledge of your data, do you need the COUNT(UNIQUE individual_id) or can it be just COUNT(individual_id)?
c) Finally, if you are interested in only last two years of data, you should probably have a WHERE predicate on your ORDER table which filters data based on ORDER_DT. Something like following:
SELECT count(unique b.individual_id),
sum((CASE WHEN NVL(ORDER_DT,TO_DATE('05-MAY-1955'))>= SYSDATE - 45 THEN 1 ELSE 0 END )) AS one_month ,
sum((CASE WHEN NVL(ORDER_DT,TO_DATE('05-MAY-1955'))>= SYSDATE - 105 and NVL(ORDER_DT,TO_DATE('05-MAY-1955')) <= SYSDATE - 45 THEN 1 ELSE 0 END )) AS Three_month,
sum((CASE WHEN NVL(ORDER_DT,TO_DATE('05-MAY-1955')) >= SYSDATE - 195 and NVL(ORDER_DT,TO_DATE('05-MAY-1955')) <= SYSDATE - 105 THEN 1 ELSE 0 END )) AS six_month,
sum((CASE WHEN NVL(ORDER_DT,TO_DATE('05-MAY-1955')) >= SYSDATE - 380 and NVL(ORDER_DT,TO_DATE('05-MAY-1955')) <= SYSDATE - 195 THEN 1 ELSE 0 END )) AS one_year,
sum((CASE WHEN NVL(ORDER_DT,TO_DATE('05-MAY-1955')) >= SYSDATE - 745 and NVL(ORDER_DT,TO_DATE('05-MAY-1955'))<= SYSDATE - 380 THEN 1 ELSE 0 END )) AS two_year
from ORDER b, address a
where b.individual_id = a.individual_id
and a.COUNTRY_CD ='US'
and b.ORDER_DT <= (SYSDATE - 380)
group by a.COUNTRY_CD ;

Hi,
As you mentioned not possible to assign the dynamic column in the query.
will give you example for generate a dynamic column name in SQL query, using this example you can achieve your requirement.
DECLARE @cols AS NVARCHAR(MAX),
    @query AS NVARCHAR(MAX)
select @cols = STUFF((SELECT distinct ',' + QUOTENAME(C.Name)
                    from [History]
            FOR XML PATH(''), TYPE
            ).value('.', 'NVARCHAR(MAX)')
        ,1,1,'')
set @query = 'SELECT [Date],' + @cols +'
             from
                select [Date], Name, Value
                from [History]
             ) x
            pivot
                max(value)
                for Name in (' + @cols + ')
            ) p '
execute(@query)

How this query executing internally
