to find the lowest a salary table

Hello guys,.
I need to find the salary low table. What is the easy way to do it.

How do you manage the links?

If you want several rows returned when there are several people with the same salary

SELECT *
  FROM(
    SELECT a.*,
           rank() over (order by salary desc ) rnk
      FROM your_table a)
 WHERE rnk = 1

If you want to handle differently the links, use a different analytic function. No doubt dense_rank or row_number.

Query to find the nth highest salary...

Hi guys,.

I can't understand this query that we got a Web site. It is used to find the nth highest salary of the employee... Can someone explain to me please each and every part of it...

The Charly is:

Select distinct (a.salary)
EMP a
where 1 = (select count (distinct (salary))
b emp
where a.salary < = b.salary)

The "BOLD" part which is the return value... is my main question about this query...

Help, please

It is called a correlated sub query. The inner query is executed for each iteration of the outer query. For example, if the table emp has 14 rows and then for each salary 14 the inner query will run.
The part

select count(distinct(sal))
from emp b
where a.sal<=b.sal

actually counts the number of treatments that are less than or equal to the treatment of the outer query.
Clearly for the King, who gets the highest salary is greater than or equal to 1 (himself). It returns the highest salary.

find the closest value in table

Hi all

I need to find the values in the "C" line which is equal or close to the values 'A' in the 2D array, and then I want to show the values of 'B', corresponding to the values of 'C' in table 2D.

How can I fix it?

Thank you!

0.9967 nearest value is 0.993807 in the 8 Cand in row B row, not 1. The differences are 2.893E - 3 and 3.300E - 3.

Subtract each value from the table C. take the absolute value of the difference. To find the index of at least using Max & Min value of B. Using autoindexing array Index, create the output array.

How can I find the subset of a table that corresponds to a set of conditions/conditions?

I have often encountered this problem in LabVIEW, probably the result of my Matlab based thinking on the tables. Suppose I have a 1 d array that consists of a real number between 0 and 2 (for example):

1.3 0.1 1.9 0.7 1.4 1.5 1.5 0.8 1.3 0.3 1.4 1.4 0.1 0.6 0.1 0.2 1.6 1.6 1.4 0.6 0.1 1.9

and I want to know the average of the subset of values greater than 0.5 and less than 1.2:

average ([0.8 0.7 0.6 0.6]) = 0.6750.

How can I find the subset of the array that satisfies the condition > 0.5 &<1.2>

For your example (values between 0.5 and 2) If you wish:

I would do something like this:

I have generated just a table of 10 random numbers between 0.0 and 2.0

The following loop sorts the data, using "range and force."
It then displays the data in the selected range.

The last step is to take the average

FROM       universe
WHERE       routine_date     = max_routine_date
;
```
You only want to view rowss whose routine_date is the maximum date in a subset. First get this subset
If the universe of data that you are interested in is just the period from January 20 to January 29, then you can start by getting all the data in this range. This is what the above subquery universe.
Now, you want to see only the rows where routine_date is the max_routine_date within this universe, for each case_id. You can use the analytic MAX function to find out what this max_routine_date.

Find the size of a table with partitions; Two questions

DB version: 11.2.0.4
Platform: Oracle Linux 6.4
The slot table MH_PKT_HEADR in UTMSBL schema has more than 5000 partitions.
Because there partitions, you cannot use just view DBA_SEGMENTS to determine the size of the table.
So, I tried to use 2 SQLs mentioned below. Query1 returned 5 GB. But Query2 has returned a value zero. Query2 is actually a note metalink mentioned below, so he cannot deceive you, I guess.

Find the element of list, table cell, node of the tree, or control by location

One of my favorite on the swing features has the opportunity to get a reference to the component UI via Container.getComponentAt (int x, int y), or a particular list item through JList.locationToIndex (Point p) (or other similar methods). I was not able to find the same or similar functionality in JFX so far... anyone can point me in the right direction?

Thank you!

I don't know a way. When I started with JavaFX I had the same issue; However, I found that I actually need to do. Swing I ever need it when I was, say, treatment the mouse clicks on a JList. In JavaFX, you can register handlers with the cells directly. This does not work in the swing (in the least, not without a huge amount of effort). As well as in the swing, how to map a mouse click to a JList to the list item corresponding was to register a listener with the JList and then move the mouse click coordinates to locationToIndex (...), in JavaFX you just save the listener with the cell:

import javafx.application.Application;
import javafx.event.EventHandler;
import javafx.scene.Scene;
import javafx.scene.control.ListCell;
import javafx.scene.control.ListView;
import javafx.scene.input.MouseEvent;
import javafx.scene.layout.BorderPane;
import javafx.stage.Stage;
import javafx.util.Callback;

public class ListTest extends Application {

  @Override
  public void start(Stage primaryStage) throws Exception {
    BorderPane root = new BorderPane();
    ListView listView = new ListView();
    listView.getItems().addAll("Apples", "Oranges", "Grapefruit", "Bananas");
    listView.setCellFactory(new Callback, ListCell>() {
      @Override
      public ListCell call(ListView param) {
        return new CustomListCell();
      }
    });
    root.setCenter(listView);
    Scene scene = new Scene(root, 300, 300);
    primaryStage.setScene(scene);
    primaryStage.show();
  }

  private class CustomListCell extends ListCell {
    private final EventHandler listener = new EventHandler() {
      @Override
      public void handle(MouseEvent event) {
        System.out.printf("Mouse clicked on list cell with %s (item number %d)",getItem(), getIndex());
        if (isEmpty()) {
          System.out.print(" (Empty cell)");
        }
        System.out.println();
      }
    };
    private CustomListCell() {
      this.addEventHandler(MouseEvent.MOUSE_CLICKED, listener);
    }
    @Override
    public void updateItem(String item , boolean empty) {
      super.updateItem(item, empty);
      if (! empty) {
        setText(item);
      } else {
        setText(null);
      }
    }
  }

  public static void main(String[] args) {launch(args);}

}

Of course, maybe it's not your use case, and you really need this feature. Someone else can have a more direct response...

Kindly help me with the request to find the data in two tables
Hello Guru

Kindly help me to recover the data from two tables-

BASEBALL
LEGAL_ENT_ID (PK)
GAME_ID (FK)
LEGAL_ENT_NM
INACTIVE_DT
DATE OF INS_TS
INS_LOGIN
DATE OF UPD_TS
UPD_LOGIN

FOOTBALL
GAME_ID (PK)
BRKR_NM,
BRKR_ISR_ID
BROKER_SYMBOL
INACTIVE_DT
BRKR_SWIFT_FLG
BRKR_INTERNAL_FLG
BRKR_CATEGORY
UPD_TS
MINORITY_FLG
BROKER_TYP
STATUS
INS_TS
INS_LOGIN
UPD_LOGIN
APP_USER
ACTIVE_FLG

and if I want fecth data from these two tables according to the following condition then it is fine with the suite of applications.

1 select distinct values only table of BASEBALL by using the following query.

SELECT DISTINCT B.GAME_ID as 'CLEARING GAME ID', B.BRKR_NM "NAME of THE GAME of COMPENSATION" OF BASEBALL A, FOOTBALL B WHERE A.BROKER_RELATION_CD IN ('FUTBRKR1', 'FUTBRKR2') AND A.GAME_ID = B.GAME_ID

2 Select all the table BRKR_NM OF FOOTBALL as well by using the query - next

SELECT GAME_ID "RUNNING GAME ID", 'NAME OF THE GAME OF EXECUTION' BRKR_NM SOCCER

Now, my query is that--

I want a query that gives me a combination of above mentioned queries... and if I tried to use Union or Union All, then she is not giving me the result as expected.

I like the result to look like who has a few conditions such as -
1 - the records in the table Football are high vs Baseball table because there is no condition to filter the records of the Football.
2 - football is a superset of records and Baseball is a subset.
3 - COMPENSATION NOM_JEU and RUNNING NOM_JEU may return the same values as well.

I want the result to be in the following form-

EXECUTION ID GAME | NAME OF THE GAME TO RUN. COMPENSATION ID GAME | DELETE THE NAME OF THE GAME.
2123 test1 2345 test5
2456 test10 2456 test10

Thanks in advance. Kindly help me.

In the output you want.
All the values of baseball;
Values of football that are matched;
But on what condition you want to match?

How to find the size of a table with CLOB

Hello
I have a table with CLOB as follows:
SQL > desc INFO_MESSAGES
Name Null? Type
----------------------------------------- -------- ----------------------------
CLNT_OID NOT NULL VARCHAR2 (16)
USR_OID NOT NULL VARCHAR2 (16)
LAST_client_msg_ID VARCHAR2 (36)
LAST_client_msg_DATE DATE
LAST_client_msg CLOB
LAST_USR_MSG_BOD_ID VARCHAR2 (36)
DATE OF LAST_USR_MSG_DATE
CLOB LAST_USR_MSG
Now I just want to find out what is the size/area total absorbed by the table (including the CLOB columns), so how can I find? I think that the usual command does not - the
Select format from dba_segments where nom_segment = "INFO_MESSAGES" is only showing 7 MB, while I think that the table has several GB of space due to the CLOB.
Also to add one more detail: when dba_segments seeking, I see a result like this:
Select * of dba_segments order by bytes DESC;
MIGRTN SYS_LOB0000111131C00008$ $ LOBSEGMENT SAMS DATA1 20690 6 1963 14528000 119013376000 <-the top row
MIGRTN this is the schema where this INFO_MESSAGES table is present.
Thanks,
OrauserN

you will need to add the segment_size of the LOB segments to the segment_size of the table. The connection between the two pieces of information you find in USER_LOBS (or the corresponding ALL_, DBA_ objects).

How to find the data in two tables are the same?
Hi people,

Suppose we have table emp01, have 10 records and create another emp02 as table

create the table emp02 in select * from emp01;

now both the table has the same data.

How to find a 'data' in the two tables are the same?
Hello
```
SELECT *
FROM emp01
MINUS
SELECT *
FROM emp02
UNION
SELECT *

How to find the rank lowest for each student using a Select query?
Hey I'm having a little trouble here

I have this table

Student - Grade

John - 8
Richard - 9
Louis - 9
Francis - 5
John - 13
Richard - 10
Peter - 12

Shades may vary from 0 to 20.

Name - varchar (50)
Grade - wide

I'm trying to generate a SQL search to search for each rank lowest for each student.

So far, I did:

Select s.name, s.grade
s student
where s.grade = (select min (grade) of student)

The result of this search returns me only the rank lowest of all ranks posted above, which is Francis - 5.

I want to find the lowest rank, but not only for Francis, but for all students in the table.

How do I do that?

Thank you in advance.
Ok

Now we head into analytical SQL:
```
with student as (select 'John' name, 8 grade, 'fail' result from dual union all
                 select 'John' name, 13 grade, 'pass' result from dual union all
                 select 'Francis',     5 grade,  'fail' from dual union all
                 select 'Peter', 12, 'pass' from dual)
-- End of your test data
SELECT   name,
         MAX (result) KEEP (DENSE_RANK FIRST ORDER BY grade) result,
         MIN (grade) min_grade
FROM     student
GROUP BY name
```
Please note that I passed ;)
