The left join - no data in the table don't want to display the data from the table one

Hello

I'm writing a query. Here is my scenario, I have two tables EMP and EMP_TYPE. I want to join both the table and even if there is no matching record in the table for EMP EMP_TYPE, I want to return the record to the EMP table and empty values of EMP_TYPE.
create table EMP
(
  EMPID   NUMBER(10,2),
  EMPNAME VARCHAR2(100)
);

INSERT INTO emp (empid,empname) values (1, 'abc');
INSERT INTO emp (empid,empname) values (2, 'xyz');
INSERT INTO emp (empid,empname) values (3, 'UNJ');

create table EMP_Type
(
  ID          NUMBER(10,2),
  EMPID       NUMBER(10,2),
  TYPE_ID     NUMBER(10,2),
  END_DATE    DATE
);

INSERT INTO EMP_Type(id, empid, TYPE_ID, END_DATE) values (100, 2, 1, SYSDATE);

select *
  from emp e
  left outer join emp_Type t
    on e.empid = t.empid
and t.type_id = 1

returns.

        EMPID     EMPNAME     ID             EMPID     TYPE_ID     END_DATE
     2.00             xyz            100.00     2.00             1.00             10/9/2012 5:18:59 PM
     3.00             UNJ                    
     1.00             abc                    


select *
  from emp e
  left outer join emp_Type t
    on e.empid = t.empid
and t.type_id = 1
and t.empid = 3

returns

        EMPID     EMPNAME     ID             EMPID     TYPE_ID     END_DATE
     2.00             xyz                 
     3.00             UNJ                    
     1.00             abc          

but instead I want

        EMPID     EMPNAME     ID             EMPID     TYPE_ID     END_DATE
     3.00             UNJ                    

Your conditions of conflict
>
and t.type_id = 1
and t.empid = 3

There is a record with t.empid 3

select *

where e.empid = 3
  and e.empid = t.empid (+)

    Also something like

    How could do?

    My current request is as

    Select distinct Curepress, lastpcirim, typeidcontainer

    BETMASTER STD left join INF BETINFO

    on the trim (STD. CUREPRESS) = substr (trim (INF. CURRENTPRESS), 1, 3)

    but I am unable to get the values separated by commas.

    Any help would be appreciated.

    Thank you

    Mahesh.

    Hi, Mahesh,

    If you want to only 1 row of output for each distinct combination of currentpress and lastpcirim?  This sounds like a job for GROUP BY.

    And you want the row to contain a list of all different typidcontainers-delimited?  This sounds like a job for the aggregate LISTAGG function.

    WITH joined_data AS

    (

    SELECT DISTINCT

    MST.curepress, mst.lastpcirim, inf.typeidcontainer

    OF betmaster STD

    LEFT JOIN betinfo ON TRIM (mst.curepress) inf = SUBSTR (TRIM (inf.currentpress)

    1

    3

    )

    )

    SELECT curepress, lastpcirim

    LISTAGG (typeidcontainer, ',')

    THE Group (ORDER BY typeidcontainer) AS container_list

    OF joined_data

    Curepress GROUP, lastpcirim

    ;

    Unfortunately, you can't say LISTAGG (DISTINCT ...), so you should always get the separate containers how you already are.  (Note that the subquery is just what you posted).

    Thanks for posting the CREATE TABLE and INSERT statements; It is very useful.  Don't forget to tell what version of Oracle you are using.  LISTAGG was new in Oracle 11.2.

    Why not add CHECK constraints (and perhaps triggers) to your tables, so that curepress and currentpress are not stored with the head or trailing spaces?  Then you wouldn't need to use the PAD in queries like this, and your code would be simpler and more effective.

    Email from Dan is not included, because his "wrk1" email does not stop it school.edu
    E-mail Mary is not included, because his 'wrk1' email is not active.
    However, I need to come back with their numbers of name registration and employee.


    Once it works, I'll add employee = number in the WHERE clause, because I only need to find a person both for the actual production.

    What I am doing wrong?

    Thank you!

    Michelle

    Hello

    WHERE is the filtering actually record the selection.

    In your case, you might want to include in your LEFT OUTER JOIN ON conditions:

    SELECT p.employee, p.recordnum, p.lastname, p.firstname
         , e.emailaddress, e.emailactive, e.emailtype
      FROM    thepeople p
           LEFT JOIN
              theemails e
           ON     p.employee = e.employee
              AND e.emailactive = 1
              AND e.emailtype = 'WRK1'
              AND e.emailaddress LIKE '%school.edu';
    

    If you put them in your JOIN conditions actually join Chronogram of table theemails that adapt to the conditions of membership.
    As you use LEFT [OUTER] JOIN unmatched chronogram thepeople table will be displayed even when the theemail table column appears with a NULL value in the output files

    I hope that I was able to unlock your brain. :-)

    Kind regards.

  • Must use the nested left join syntax?

    I am currently an editing view. The view has one with a followed left join to an inner join such as this:

    Select
    T1.a,
    T2.b,
    T3.c
    Of
    (select 1 as a Union double all the)
    Select 2 as double
    ) t1
    left join
    (select 1A, 11 b of all the double union)
    Select 2A, 12 b of the double
    ) t2
    on t1.a = t2.a
    Join
    T3 (select 11 b, 14-c double)
    on t2.b = t3.b;
    / * - Try out: -.
    A, B AND C
    ------- ------- -------
    1-11-14
    */

    The inner join converts left join in an inner join "de facto"? should I use nested join syntax in order to get the other ranks:

    Select
    T1.a,
    T2.b,
    T3.c
    Of
    (select 1 as a Union double all the)
    Select 2 as double
    ) t1
    left join
    (select 1A, 11 b of all the double union)
    Select 2A, 12 b of the double
    ) t2
    on t1.a = t2.a
    Join
    T3 (select 11 b, 14-c double)
    on t2.b = t3.b;
    / * - Try out: -.
    A, B AND C
    ------- ------- -------
    1-11-14
    */

    Sorry, just saw your last join condition now:

    on t2.b = t3.b;
    

    This results in a JOIN INTERNAL to the EXTERNAL table JOINED to, will certainly lead to a result of diminshed set - not quite the same that forced an INNER JOIN, but the result is the same, Yes. So there are indeed of equivalence.

    This, however, would not have resulted a reduced resultset:

    on t1.a = t3.a;
    

    But of course it is not possible, since the t3 has a column "a".

  • Using data from the control table

    Hello

    I would like to use the data entered in a table to automate volume/sequence of airflow for a test Chamber. As shown in the screenshot of control table, the first column indicates the number of iterations by elements of array in a series of tests and the second data column specifies the length of each line sequence. Entries in the other columns are specific to different valves and specify values set required in the flow meter.

    I guess my question is how can I index/assign each column of the table such that the data to exploit the respective valves are obtained in subsequent iterations all acquire simultaneously with data from other components in the order? While I recognize that the solution may be very simple, I searched on through various examples and messages on the tables and the tables without knocking on a solution. The attached .vi allows me to be a part of the series of tests.

    Best regards

    Callisto

    Hi Callisto,

    If I understand your question then the solution is actually quite simple. The important point to keep in min is the fact that the Table control can actually be treated as an array of string. You can then use all the traditional table manipulation tools and techniques to manipulate your data as you wish. For example, use the Array Index function to retrieve specific columns and then if you want to spend the individual elements in a column in a loop, wire the table until the loop and ensure that indexing is enabled. If you then want to use these data elements to control your test application, you can convert a portion of the resulting string in more useful to digital.

    All these concepts are illustrated in the attached VI. I hope this helps, but let me know if you have any other questions.

    Best regards

  • How to copy the data from the indicator table 1 d to the Clipboard

    Is it possible to copy data from table 1 d indicator to the Clipboard as a text and for more than one cell?

    I use LV8.6.

    Sorry, I wasn't sure if it was available in 8.6, apparently not.

    You could create an indicator of fine print and use 'picture to a worksheet string' to complete. Now, you can just cut & paste the text instead.

  • Using the calendar function to select and read data from MS access tables?

    Hello

    I woke up in the learning of database in no time. I'm using Labview 9 to create a table based on DDMMYY hhmmss format. I can write data to the table in access. The picture will be 24 hours before a new table will be created. However, I find that this concept is not very gd as time goes by, I'll have a lot of paintings for example after 6 months.

    1.I would like to create a calendar (similar to the system clock) in labview, through which the user can click and select, which will then open and retrieve the data. Inorder to do I think I need to create queries and the relationship in MS Access? can any1 advice? Please give as much detail as possible.

    2.i can access data and display in labview. However, I want to display the data and plot in the chart. For instance, coloum b, c and trace on the graph in a proceeding for the analyst.

    3. how to generate a report to an email in a file to document the daily data inserted. I can do it in labview?

    Any help would be much appreciated.  If you have examples of code and don't mind not to share, I would be very grateful.
