SQL to find the same DATE?

I wanted to do a check based on a Table of 10g.

customer_id, DATE

Basically, I wanted to do a check, make sure that each customer_id has a SEPARATE DATE, therefore, for the returned data.
the DATE must be unique and not repeat, I know its probably something super simple, but I wanted to analyze the entire
table and do a count of these instances:

It would be nice:

12345 20101001
25487 20101002

This would not be permitted:

12345 20101001
12345 20101001 - double date
25487 20101002

a varchar2 column, it is in format YYYYMMDD, not not using type DATE, just FYI. Ago, I know, I have not said that upward.

I would use a SELF JOIN here, not a lot of experience in this.

Hello

Here's one way:

WITH     got_cnt          AS
(
     SELECT     customer_id
     ,     dt          -- DATE is not a good column name
     ,     COUNT (*) OVER ( PARTITION BY  customer_id
                                ,              dt
                    )      AS cnt
     FROM    table_x
)
SELECT    *
FROM       cot_cnt
WHERE       cnt     > 1
ORDER BY  customer_id
,            dt
;

A self-join anouther way to find duplicates, but may not be as effective. In addition, what would you like if it was be stored 3 (or more) with the same customer_id and dt?

Oh!
If you want to display the columns are duplicated, you can do something even more fast and simlpler:

SELECT       customer_id
,       dt
,       COUNT (*)     AS cnt
FROM       table_x
GROUP BY  customer_id
,       dt
HAVING       COUNT (*)     > 1
;

  • DTS moves to the same data store

    Greetings,

    We are short v5.5u1 esxi and vcenter device with DTS clusters installation using thresholds to space only at this time. We do not limit our VM to place records on the same data and store, and in view of the virtual machine can have his records scattered across data warehouses in a cluster of the DS.

    We have many events that seem to do nothing is represented below.  Everyone agrees that something actually happens or vcenter turns his wheels?

    Thank you

    Ron

    Just answered my own question... it has to do with my scattered placement of vmdk. Since the vmx file lives on a given data store, the event shows that the activity... However if you check the DTS tab for the cluster data store you will find the disks associated with the virtual machine on other data warehouses were actually moved.

    Because in the second example you also select rows that have a nonzero component.

    The first example selects only rows that are 00:00:00

  • Find the minimum date on multiple columns

    Hello

    I have two questions to find the minimum date on several columns:
    1. need a select query that should JOIN two tables and return any information (CASSEDTL) table with minimum date out of DATEISSUED, DATEPLACED, DATEENTERED and STATDATE.
    2. need of an update query that should update all cases in the CASEDTL table with the minimum date of DATEISSUED, DATEPLACED, DATEENTERED and STATDATE.

    INSERT INTO CASEMSTR VALUES (1, '1 JUL 2007', '1 JUL 2007', '12 JUL 2007');
    INSERT INTO CASEMSTR VALUES (2, '1 JAN 2008', '1 JAN 2008', '21 JAN 2008');

    FROM CASEDTL CD
        INNER JOIN CASEMSTR CM
            ON CD.CASENBR = CM.CASENBR;
    Need to know what is the best way to complete the new Date of RRS? Receive a new date should be the minimum date of DATEISSUED, DATEPLACED, DATEENTERED and STATDATE. And also how do I write an update statement unique to upade date of receipt in the detail table?

    Any help would be appreciated! Thanks in advance!

  • How to create two different smart albums with photos with the same date?

    I created a smart album by using 'Date is' and ' keyword is EAA.»  (The photos have a keyword like "EAA" or "Flower".  Photos of keyword EAA & flower have the same date.)  When I use "Corresponding to all" are has no pictures in the album.  When I use "Match any" all the photos are in the album - EAA & flower.  I would like an album with only pictures of CEA for that date and another album with photos of flower with the same date.

    I get the same answer.  I can get the date and to a key word to work with 'all' selected, but not date and keywords.  So you will need two smart albums: one with date and ECA ('all' selected) and the other with date and flowers ('all' selected).

    Use the file menu option ➙ new Smart Album.

  • Cannot find the locale data files. Please reinstall

    I had a problem with Google Chrome, so I uninstalled via the control panel. I then reinstalled and I have this problem. I always present in my programs in the watched folder, but when I select to demolished, he said ' wait until the current program has finished install or changing.» I have no other program install or change. If I try to open Google, anywhere Progams, taskbar, all programs or directly from the .exe LocalApps it gives me the "could not find the locale data files. Please reinstall.

    I found the answer to my question. It seems that you can build processes, I don't understand why. For example I had a problem with my windows Explorer crashing. I disabled all the startup process of msconfig.

    In my view, there must be something in there that closes a completed process.
    Then I had, unknown to me, when I posted this problem, six or seven cases Google chrome showing the the Task Manager process tab. When I quit all instances of Google, I was able to finish the removal process and re - install Google Chrome.
    I just checked right now and I have six Google shown 3 rundll32.exe and two taskeng.exe bodies. I've never seen no more than one instance of anything in this tab before today.
    Disabling all startup stuff does not solve my problem to explore some way so I'll allow them once again.
    Thank you for helping me and I hope that someone can get useful information from my travels.

    I have no problem space or privileges on the two schemas of the DB. I just want to know what the best technically?

    Thank you

    You need a separate data by application source otherwise each application will overwrite the other that they will share the same relational tables, if you want the planning application to work properly then two apps = two data sources
