Searching for the same table

Hello

I have a table that contains the following information

RowID Asset Version TYPE
1A 1 345 PPS
B2 2 345 pps
A3 3 345 pps
F4 1 321 ppp
G5 2 321 ppp
H6 333 1 pps


I need a query for the version the most up-to-date assets
The final result after the query should be:

A3 3 345 pps
G5 2 321 ppp
H6 333 1 pps


Help please 
SELECT   asset, MAX (VERSION), TYPE

  • Sinlge select query in the diff for the same table (same Structure) diagrams

    Scenario:

    Table XYZ is created in detail a.
    After a year, the old data of the previous year could be moved to another schema. However in the other schema of the same table name would be used.

    For example

    A schema contains XYZ table with data from the year 2012
    Schema B contains XYZ table with data for the year 2011
    Table XYZ in the two schemas have an identical structure.

    So we can draw a single select query to read the data from the tables in an effective way.
    For example select * from XYZ so including date between October 15, 2011 to March 15, 2012.
    However, the data resides in 2 different schema altogether.


    Creating a view is an option.
    But my problem, there are ORM (Hibernate or Eclipse Top Link) layer between the application and the database.
    If the queries would be constituted by the ORM layer and are not generated by hand.
    So I can't use the view.
    So is there any option that would allow me to use only query on different scheme?

  • Search for the nearest value table

    IM wondering if its possible to find a 1 d table worth, if it is not found, then find the nearest match. IM using the 'double' data type and I need at least an accuracy of 4 decimal point in the research.

    For now, im rounding decimal values to the nearest integers from you, but it is not effective at all. Im getting a lot of unwanted split in the plot. I need to be able to search for the decimal points. I found this function "About Equals.VI" starting from a previous thread. Even that uses the concept of the rounding.

    I enclose 3 screws "0.8 & 0.4.VI" are that I created, rounding decimals nearest digit.

    The "approximately equal" is the one I found online.

    The 3rd is I try to mess with what I can find as close a match.

    Y at - it a trick to work around this problem?

    Thank you

    This VI uses the first type of step 3 in your data.  Since you said that you can get the data, you can drop the in VI.

    At the end where I calculate the slope, you can use a linear adjustment if you have full or professional LabVIEW.

  • Support for mandatory request - insert, select from the same table

    Hi all

    I need your help to write queries effectively.
    Oracle Version: 10.2.0.3.0
    OPERATING SYSTEM: UNIX

    I have a METRICS_TBL that is mentioned below table.

    CYCLE_DATE METRIC VALUE
    08/17/2008 COST-TV 100
    08/17/2008 COST-JOURNAL 50
    08/17/2008 COST-POSTALMAIL 25
    08/17/2008-PROD-TV 10
    08/17/2008-PROD-JOURNAL 25
    08/17/2008-PROD-POSTALMAIL 5

    Any data above, I have to add (Insert into select METRICS_TBL METRICS_TBL) at the same table with the records as mentioned below.

    2008-08-17 COSTPERPROD-TV 10
    08/17/2008-COSTPERPROD-LOG 2
    2008-08-17 COST PROD-POSTALMAIL 5

    Basically, I need to calculate the cost per product for each category. Depending on the settings available, metric should also be changed as COSTPERPROD and values should be cost/prod under each category.

    Can someone help me with the query.

    Thank you

    Something like this:

    INSERT INTO metrics_tbl
(cycle_date, metrics, value)
SELECT cost.cycle_date
         , 'COSTPERPROD-'||cost.mtype
         ,cost.value / prod.value
FROM  (
   select cycle_date,substr(metrics, 1, 4) mtype, substrmetrics,instr(metrics,'-')+1) mmetric
   where substr(metrics, 1, 4) = 'PROD'
   ) prod
INNER JOIN (   select cycle_date,substr(metrics, 1, 4) mtype, substrmetrics,instr(metrics,'-')+1) mmetric
   where substr(metrics, 1, 4) = 'COST'
   ) cost on cost.cycle_date = prod.cycle_date and cost.mmetric = prod.mmetric

    Ideally you would divide your METRICS column into two: one for the thing you're measuring (e.g. TV or NEWSPAPER) and the other for the metric (COST, PROD, COSTPERPROD etc.). That's what I did in the views online. Without it, it's kinda a mess and behave so, if the table becomes much more.

  • Updated with the values in the same table, for other records corresponding to conditions

    Hi Experts,

    Sorry do not provide the structure of the table (it is a simple structure)

    I have a requirement where I need to update the columns of a table based on the same table with some match empid and date values. If the date and empid match so I have these values to any other folder and update of one who is not having details of Office . I need the Update query

    Before the update my array of values is as below

    Sort_num Emp_id Bureau start_date

    1 101 AUS 01/01/2013
    2 101 01/01/2013
    3 101 15/01/2013
    4 103 USA 01/05/2013
    5 103 01/01/2013
    6 103 05/01/2013
    7 104 FRA 01/10/2013
    8 104 10/01/2013
    9 104 01/01/2013

    After update my table should be as below

    Sort_num Emp_id Bureau start_date

    1 101 AUS 01/01/2013
    2 101 AUS 01/01/2013

    8 104 FRA 01/10/2013
    9 104 01/01/2013

    Thanks in advance

    I don't have the time to create the table with the data, but basically, you should be able to code the following text

    update one table

    Office set = (select desktop in table b where b.emp_id = a.emp_id)

    and b.start_date = a.start_date

    and b.office is not null

    )

    where is ([as well as overall query])

    and a.office is null

    In my opinion, who will do the trick.

    What I want is less than

    -Search for a line more low which is CON_DATE > = to_date ('01-NOV-1998', ' MON-DD-YYYY "") AND STATE = 30658 and get the second row whose state = 30658 but having separate con_date

                               or CON_DATE = > = to_date (November 1, 1997 ',' MON-DD-YYYY "") AND STATE <>30658 & get the second row including State = 30658 but having separate con_date

    and lower (status) = 'active '.


    and get another line that extends beyond the found line, but having separate con_date (no operation of the same day.)

    I tried to do it with and then attach it again with the same table, but I don't get different results...

    Please advise.

    Thanks for trying.

    First find a line that corresponds

    ((CON_DATE > = to_date (1er novembre 1998 ', ' MON-DD-YYYY ") AND STATE = 30658))

    or (CON_DATE > = to_date (November 1, 1997 ',' MON-DD-YYYY "") AND STATE <> 30658))


    8 second get/check the following line immediately for offs_id even that has different con_date, that is superior to prev con_date but State should be 3065


    If offs_id found then return else throw line...


       


    Thus, in addition to the conditions that I listed previously, there must be a line with the same offs_id, which has a con_date later and the State concerned; is this fair?

    You can use a self-join to see if there is such an extra line:

    WITH params AS

    (

    SELECT TO_DATE (November 1, 1998 ', 'DD-Mon-YYYY') AS later_threshold_date

    AS target_state 30658

    11900 AS target_offs_id

    OF the double

    )

    SELECT s.offs_id

    OF s sor_off

    JOIN params p ON s.offs_id = p.target_offs_id

    AND ((s.con_date > = p.later_threshold_date))

    AND s.state = p.target_state

    )

    OR (s.con_date > = ADD_MONTHS (p.later_threshold_date, 12))

    AND s.state <> p.target_state

    )

    )

    JOIN sor_off ON s2.offs_id = s.offs_id s2

    AND s2.con_date > s.con_date

    AND s2.state = p.target_state

    GROUP BY s.offs_id

    ;

    The only difference between this and the previous solution is the last join, in other words, the 3 lines of code just before the GROUP BY clause.

  • First occurrence but not in the same table

    As we know, to search for the first occurrence of a particular record, we go with the MIN function. It is however, if all of your records are in the same table.

    My scenario is a little different. I have 4 tables (maybe more), but keeping this is simple for the exercise. I need to find the first occurrence of a student who appear in a table and this registration Date. The trick is to NOT include this student in the following tables. To do this, I can use SQL or PL/SQL.

    Thanks in advance.

    Hi all

    I have a simple table of database with over any dependant on other tables. In my table one of my name of the column as "Gander".
    Since I have given in table mod "or F. What is my requirement in simple with table search page that I want to search with Gander field also with other areas.
    while I want to show that gender as LOV in the search panel.
    I tried with when we have a relationship with some other table.but how to create LOV to field when the field in the same table only.

    as M or F even use cases or not like.


    Concerning
    Siva

    Siva,

    What is your version of JDev? What technology you are using (BC4J?)?

    Assuming you are using BC for the model, you tried to create another object view based on query something like

    select distinct gender, gender from your table

    and then use this VO for LOV?

  • Photosmart C410A: HP Solution Center install on 2 PCs for the same printer

    I have two PCs running Windows 7 Professional 64 - bit and a HP Photosmart C410A printer, wireless connections to my network.  The solution Center has worked well on the first PC, it was installed on.  I tried to install it on my new PC, but I get an error on USB hardware and software; It will not attempt to connect and install wireless.

    My question: can you run Solution Center HP of two different PC for the same printer Photosmart C410A?

    Thank you.

    Yes,

    You can install the HP Solution Center software on several computers connected to the same netowrk as your printer.

    Try following these steps to solve the USB error during installation:

    Click the Start button and type folder in the search bar, then open the Temp folder indicated.

    Open the last HP installation folder that begins with 7z (e.g. 7zs1234)
    Open the installation folder.
    Find the file usbready.exe and rename it to usbready.old.exe
    Navigate to the main extraction folder (folders that begins with 7z) and run the Setup.exe file.

    Now follow the installation and check for the difference.

  • Name of the file and the measure in the same table?

    Hello

    I wrote the following VI which opens each image file in a folder and measure a certain size on the image. He then puts the result in a table.

    The table has a column and N lines since I N images in my folder. How can I change this VI so that it puts the name of the file in the same table as well as the measurement?

    I want the table to look like:

    File1 measurement1

    File2 GCA2

    ...

    and so on.

    Currently, it just shows

    measurement1

    GCA2

    ....

    and so on.

    The VI are:

    You cannot use the Table Express. Like the properties page says: this is for digital data. You will need to use a bit of real LabVIEW to create the table. A table is simply a string 2D array. Convert the digital chain, build an array of 1 d of the filename and numberic strings and use a shift register to build a 2D array. Something like the code below.

  • Component used to self referencing the same table?

    Hi all.. I'm new to ADF... I have to implement article comment in my application... I don't have only one table to store comments and responses... observations and replicas are identified by a column 'comment_type' that stores the 'R' for the answers and 'C' for the comments... so I have to use the same table again and again to find out if a comment is to have an answer... so which is the best method to apply this and which component is appropriate for this implementation?

    Any help would be great-Jey

    User, tell us your version of Jdev, please!

  • comparing string values in the same table

    I have a table with ID (14 digit string values) starting with "A". Ex: A21849B1020792. There may be a different ID with the same substring 'B1020792' in the same table, example: A12349B1020792. If this happens, the ID of the last creation date of must be returned in the result. In other words, comparison is done on the same table. "In the example provided, say A12349B1020792 has the date of 1 January 2015 'and A21849B1020792 has date February 1, 2015", since A21849B1020792 has the most recent date, the result must contain only A21849B1020792.

    ID create_date

    ---                              ------------------

    A21849B1020792 02/01/2015

    A12345B1234567 01/03/2015      

    A43567B1234567 01/04/2015      


    Here's the query I used:

    substr (a.id, 7) select sc, max (a.create_date) cd1

    of table a, table b

    where a.id! = b.id

    and substr (a.id, 7) = substr (b.id, 7)

    and a.id like 'A %' and b.id like 'A %' / * (I used a % because I am interested only IDs that begin with A) * /.

    and a.id ('A12349B1020792', 'A21849B1020792','A12345B1234567 ','A43567B1234567')

    Group of substr (a.id, 7);

    Result:

    ---                    ------

    B1020792 02/01/2015

    B1234567 04/01/2015

    There is one thing that I'm not able to do with my request, that is, be able to get real IDs list and not list of substrings. If I added a.id column in the select clause and the group by clause, the query includes both by substr (a.id, 7) and a.id and as a result, the query returns four lines as below:

    substr (a.id, 7) select sc, max (a.create_date) cd1, a.id ID

    of table a, table b

    where a.id! = b.id

    and substr (a.id, 7) = substr (b.id, 7)

    and a.id like 'A %' and b.id like 'A %' / * (I used a % because I am interested only IDs that begin with A) * /.

    and a.id ('A12349B1020792', 'A21849B1020792','A12345B1234567 ','A43567B1234567')

    Group by substr (a.id, 7), a.id.

    Result:

    ---------

    sc                    cd1                      ID

    01/01/2015 A12349B1020792 B1020792

    B1234567 01/03/2015 A12345B1234567

    B1234567 01/04/2015 A43567B1234567


    My goal is to retrieve a list of all the unique identifiers that have the later dates.

    If it makes sense to treat the first 6 characters of the ID separately from the rest of the id in this problem, maybe it makes sense to store those two parts of the id in two different columns.  Relational databases work best when each column of each row contains 1 single piece of data (at most).  It is so fundamental to the design of table that he called the first normal form.

    Given that the two parts are stored in column 1, so you can something like this Request Top - N:

    WITH got_r_num AS

    (

    SELECT r.id

    r.create_date AS cd1

    , RANK () OVER (PARTITION OF SUBSTR (r.id, 7))

    ORDER BY r.create_date DESC

    ) AS r_num

    FROM table_x g - g for data values

    JOIN table_x r - r for related values

    ON SUBSTR (r.id, 7) = SUBSTR (g.id, 7)

    WHERE g.id IN ('A12349B1020792'

    , "A21849B1020792".

    , "A12345B1234567".

    , "A43567B1234567".

    )

    - AND g.id LIKE 'A %' - if necessary.   The above condition ensures already g.id start with "A".

    AND r.id LIKE 'a % '.

    )

    SELECT id, create_date

    OF got_r_num

    WHERE r_num = 1

    ;

    If you would care to post CREATE TABLE and INSERT instructions for the sample data, and then I could test this.

  • If I have the two LOV in the same table then how to connect when I select first and second LOV value also change?

    Mr President

    If I have the two LOV in the same table then how to connect when I select first and second LOV value also change?

    My two fields are FLOW AND DR_NAME

    FLOW = ACCT_ID

    DR_NAME = ACCT_NAME

    I created with success of LOV for these fields.

    First LOV gives acct_id in the debit field and second LOV gives the value of acct_name to dr_name.

    How can I report these lov, it's that when I change my acct_id then acct_name also change

    I have these two tables

    CREATE TABLE "NOM"  (
  "ACCT_ID" VARCHAR2(7) NOT NULL ENABLE, 
  "ACCT_NAME" VARCHAR2(50) NOT NULL ENABLE, 
  "O_BAL" NUMBER(13,2),
  CONSTRAINT NOM_PK PRIMARY KEY ("ACCT_ID")ENABLE
   
   );
CREATE TABLE "VOUCHERDET" (
  "V_ID" VARCHAR2(9) NOT NULL ENABLE,
  "LINEITEM" NUMBER ,
  "DEBIT" VARCHAR2(7) , 
  "DR_NAME" VARCHAR2(50), 
  "CREDIT" VARCHAR2(7) , 
  "CR_NAME" VARCHAR2(50), 
  "PARTICULARS" VARCHAR2(100), 
  "AMOUNT" NUMBER(21,2),

    so, instead of this second ActId, choose ACCT_NAME:
