• example of model clause

  I want to learn about the model clause, if everyone learned pls share your knowledge, it will be useful to everyone, the examples provided in the oracle documentation are really pathetic. pls share your knowledge with which any person can understand, as good examples
  
  What is a measure, and what it does?
  What is a size clause?
  What is the rules how to use and what it does.
  
  If oracle documentation is reading my post, hope that they will understand how it is difficult to understand the examples provided in the oracle documentation

  If you are familiar with the OOPS concepts, I think it will be very easy to understand the concept of MODEL... I would try to explain with a simple example.

  Think of a table, for example POPULATION_ARRAY, that allows to store the population for countries for different years. Means of the table are defined as

  POPULATION_ARRAY (number of people) indexed by [COUNTRY_ID, YEAR]

  Normally, we define the values as below for the tables...

  
      population_array[INDIA,2012].population := 130,000,000;
  

  The ID of the country and the YEAR here are the dimensions. The POPULATION is a MEASURE.

  Another element in the array will be

      population_array[CHINA,2012].population := 150,000,000;
  

  Now suppose I want to do a calculation to know the population on 2022 on an explanation that the population will double (!) for these countries in 2022.
  Will let you know how you can do this in EXCEL. Same thing can be done using the MODEL. (And much more...!)

  For simplicity we will fill all these data in a single table.

  SQL> create table country(country_id varchar2(30),
    2  year number,population number);
  
  Table created.
  
  SQL> insert into country values('INDIA',2012,130000000);
  
  1 row created.
  
  SQL> insert into country values('CHINA',2012,150000000);
  
  1 row created.
  
  SQL> commit;
  
  Commit complete.
  
  SQL> select * from country;
  
  COUNTRY_ID                           YEAR POPULATION
  ------------------------------ ---------- ----------
  INDIA                                2012  130000000
  CHINA                                2012  150000000
  

  Here we do not have values for 2022.Now how to calculate and display the results using MODEL?

  As mentioned, the dimensions are COUNTRY_ID, YEAR. The fatc that interests us is the POPULATION.

  Thus, the application of the MODEL will be as follows, for INDIA

  SQL> select *
    2  from country
    3  model
    4   dimension by (country_id,year)
    5   measures(population)
    6    rules upsert all
    7     (
    8      population['INDIA',2022] = population['INDIA',2012]*2
    9     );
  
  COUNTRY_ID                           YEAR POPULATION
  ------------------------------ ---------- ----------
  CHINA                                2012  150000000
  INDIA                                2012  130000000
  INDIA                                2022  260000000
  

  So here we use MODEL as an EXCEL spreadsheet.

  You will notice that us hard coded name of the country here, which can be avoided using ANY keyword and cv (present value) function.

  SQL> select *
    2  from country
    3  model
    4   dimension by (country_id,year)
    5   measures(population)
    6    rules upsert all
    7     (
    8      population[ANY,2022] = population[cv(),2012]*2
    9     );
  
  COUNTRY_ID                           YEAR POPULATION
  ------------------------------ ---------- ----------
  INDIA                                2012  130000000
  CHINA                                2012  150000000
  CHINA                                2022  300000000
  INDIA                                2022  260000000
  

  Suppose now, I do not have the details of the USA for 2012. But I guess that the US population is half that of INDIA. That can be added as follows

  SQL> select *
    2  from country
    3  model
    4   dimension by (country_id,year)
    5   measures(population)
    6    rules upsert all
    7     (
    8      population['USA',ANY] = population['INDIA',cv()]/2,
    9      population[ANY,2022] = population[cv(),2012]*2
   10     );
  
  COUNTRY_ID                           YEAR POPULATION
  ------------------------------ ---------- ----------
  INDIA                                2012  130000000
  CHINA                                2012  150000000
  USA                                  2012   65000000
  CHINA                                2022  300000000
  INDIA                                2022  260000000
  USA                                  2022  130000000

  Hello, I am trying to get my internal speakers to work. They worked fine up until I had to repalce my hard drive. I finailly got all my drivers installed and updated on the site variouus.  Now, when I check my internal speakers (no system sounds) I can not find the make and model of them.  All I can identify is that I have.  That the drivers are missing. No part number for the company name, etc. is connected with the internal speakers.

  Thank you

  I don't know what you mean by getting the drivers from "various sites." The only place to get the drivers for the hardware that is installed with your Dimension is the Dell Web site.

  There is only one pilot audio for your Dimension 3000 and it's here:

  Of course if you added your own sound card you need get the drivers of the mftr site. but provided with your Dell printer's on the motherboard, and those are the drivers for it. MS - MVP - Elephant Boy computers - don't panic!

  I have a dell inspiron 530, the motherboard is bad. I was going to get the same model. but I was told that windows will not work on the new. even if they are the same type of motherboard

  Make the point by replacing with the same card mother and model is interpreted as reinstallation on the same computer.

• Query on the physical Architecture, the logical Architecture and model

  Hi Experts,
  I have a confusion regarding the physical, logical and model Architecture Architecture. Please tell me what type of information or data, these three above hold.
  Thank you

  Physical architecture contains information about the physical configuration of your environment e.g. nameservers, jdbc, usernames, passwords etc connection strings

  The logical architecture provides an abstraction layer that allows to group by similar contexts of physical architecture components that reside in different locations/environments.

  Patterns are reversed representations of objects in your physical architecture that is tables, flat files, etc. The models are used as sources and targets in your UI design

• Questions using the 'Make' variables and 'Models' file rename templete

  I currently have two import of models of change of name of the file. I chose according to the CF card camera came. I tried LR4 and now the LR5 use a built-in variable to 'Do' and 'model '. This way I just having a name change model and do not have to worry about forgetting to change the model. Am I missing something here? All the info is in the EXIF data. Why can't LR out?

  Sample of my two models:

  "Nikon_D700_ {Date (MM)"} {Date (DD) '} {Date (YYY) '} _ {filename number suffix}.

  "Nikon_D300_ {Date (MM)"} {Date (DD) '} {Date (YYY) '} _ {filename number suffix}.

  Sample of what I want:

  "_ _ {Model}' {brand} {Date (MM)"} {Date (DD) '} {Date (YYY) '} _ {filename number suffix}.

  That I lose my mind or is the variable renaming works as expected and I use it wrong?

  Thanks in advance!

  Conrad

  Have you actually tried import using this model? It works when I try. Yes, the example seems strange... but it should still work. So what happens when you try?

  BTW, you may find that the 'model' may also include the 'make' (it does on my Canon cameras).

• Use of the place where and having clause

  Hi all
  
  I have always a doubt as to the use of HAVING and WHERE clause.
  Suppose I have table T1 with a single column C1

  who data following INSERT scripts
  
  INSERT INTO T1 VALUES ('A');
  INSERT INTO T1 VALUES ('B');
  
  INSERT INTO T1 VALUES('C');
  
  INSERT INTO T1 VALUES ('A');
  INSERT INTO T1 VALUES ('B');
  
  INSERT INTO T1 VALUES ('A');

  ==============
  B = 2
  A = 3
  
  Then out of query 1 and 2, approach who is right?
  
  (1) SELECT C1, COUNT (C1) FROM T1

  In SQL, it is always better to filter data as soon as possible of the moment.
  In your example, the WHERE clause would be right now:

  SQL> explain plan for
    2  select c1,count(c1)
    3  from t1
    4  where c1 != 'C'
    5  group by c1
    6* order by c1 desc;
  
  Explained.
  
  SQL> select * from table(dbms_xplan.display);
  
  PLAN_TABLE_OUTPUT
  ----------------------------------------------------
  Plan hash value: 3946799371
  
  ----------------------------------------------------
  | Id  | Operation          | Name | Rows  | Bytes |

  |   0 | SELECT STATEMENT   |      |     5 |    10 |
  |   1 |  SORT GROUP BY     |      |     5 |    10 |
  |*  2 |   TABLE ACCESS FULL| T1   |     5 |    10 |
  ----------------------------------------------------
  
  Predicate Information (identified by operation id):
     2 - filter("C1"!='C')
  
  18 rows selected.
  
  SQL>
  

  As you can see that the filter is applied during the analysis of T1.

  Whereas in the case of HAVING:

  SQL> explain plan for
    2  select c1,count(c1)
    3  from t1
    4  group by c1
    5  having c1 != 'C'
    6* order by c1 desc;
  
  Explained.
  
  SQL> select * from table(dbms_xplan.display);
  
  PLAN_TABLE_OUTPUT
  ----------------------------------------------------
  Plan hash value: 3146800528
  
  ----------------------------------------------------
  | Id  | Operation           | Name | Rows  | Bytes |
  ----------------------------------------------------
  |   0 | SELECT STATEMENT    |      |     6 |    12 |
  |*  1 |  FILTER             |      |       |       |
  |   2 |   SORT GROUP BY     |      |     6 |    12 |
  |   3 |    TABLE ACCESS FULL| T1   |     6 |    12 |
  ----------------------------------------------------
  
  Predicate Information (identified by operation id):
     1 - filter("C1"!='C')
  
  18 rows selected.
  
  SQL>
  

  The analysis is performed after all groups have been calculated: which was calculated in vain, because it will be further filtered because of the HAVING clause.

  In general, I would like to use as a guide: If you do not use aggregate functions in your predicate in the HAVING clause, set this predicate to the WHERE of your query part.

  I realized the answer when I put:

  Really? When I do the same change, in other words, if I change the line that says initially

  m_1[2]=ITERATION_NUMBER 
  

  TO

  m_1[3]=ITERATION_NUMBER 
  

  then the following 2 rows are different:

• Helps the model clause. Date field in the Dimension

  Hello, all.
  
  I'm having a problem with the clause type in my query. In my view, it may be a misunderstanding on my part, but I can't find any documentation that is opposed to the use of the date fields in the dimensions of my model.
  
  Given these data;
  

  LOGDATE               SHIFTNAME  BUILDING  UNIT  DOORNUMBER  INOUT    EVENTCOUNT
  2012-02-01 06:00:00      A        1800      R      Door 4     Out         14
  2012-02-01 06:00:00      A        1800      R      Door 4     In          15
  2012-02-01 18:00:00      D        1800      R      Door 4     Out         17
  2012-02-01 18:00:00      D        1800      R      Door 4     In          19
  2012-02-02 06:00:00      A        1800      R      Door 4     Out         14
  2012-02-02 06:00:00      A        1800      R      Door 4     In          14
  ...

  I write my SQL like this:
  

  SELECT logdate, shiftname, building, unit, doornumber, inout, eventcount
    FROM door_events
   WHERE building='1800' AND unit='R' AND doornumber=4
   MODEL DIMENSION BY (logdate, shiftname, building, unit, doornumber, inout)
         MEASURES (eventcount)
        RULES ()

  And I get the expected result. (The same table as above) But when I try to add rows using rules, I get no new line until the LOGDATE field is a date. For example, by using this code, I expect to get a new line, with a 100 EVENTCOUNT (and other fields as written) but I stiill get the same set of data (no line is added)
  

  SELECT logdate, shiftname, building, unit, doornumber, inout, eventcount
    FROM door_events
   WHERE building='1800' AND unit='R' AND doornumber=4
   MODEL DIMENSION BY (logdate, shiftname, building, unit, doornumber, inout)
         MEASURES (eventcount)
         RULES (eventcount[SYSDATE,'X','1800','R',4,'In'=100)

  However, when I turn the LOGDATE field in a CHAR data type (and make the SYSDATE a TANK in the same way) with the code below, all of a sudden I get the line I was expecting!
  

  SELECT TO_CHAR(logdate,'YYYY-MM-DD HH24:MI:SS') logdate, shiftname, building, unit, doornumber, inout, eventcount
    FROM door_events
   WHERE building='1800' AND unit='R' AND doornumber=4
   MODEL DIMENSION BY (logdate, shiftname, building, unit, doornumber, inout)
         MEASURES (eventcount)
         RULES (eventcount[TO_CHAR(SYSDATE,'YYYY-MM-DD HH24:MI:SS'),'X','1800','R',4,'In'=100)
  
  
  LOGDATE               SHIFTNAME  BUILDING  UNIT  DOORNUMBER  INOUT    EVENTCOUNT
  2012-02-01 06:00:00      A        1800      R      Door 4     Out         14
  2012-02-01 06:00:00      A        1800      R      Door 4     In          15
  2012-02-01 18:00:00      D        1800      R      Door 4     Out         17
  2012-02-01 18:00:00      D        1800      R      Door 4     In          19
  2012-02-02 06:00:00      A        1800      R      Door 4     Out         14
  2012-02-02 06:00:00      A        1800      R      Door 4     In          14
  ...
  2012-02-07 15:18:33      X        1800      R      Door 4     In          100

  Can someone explain this behavior? I intend to do some calculations on the LOGDATE dimension and I would like to keep it as a date. Thanks in advance for any help!

  I do not get the same result. When I use SYSDATE, I don't get the extra line. When I use TO_CHAR (SYDATE...) as you say, I still don't get the extra line.

  However, when I use a constant date, such as TO_DATE (' 2012/02/07 02:00 ',' YYYY-MM-DD HH24:MI:SS'), then I get the extra line.

  This behavior is described in http://docs.oracle.com/cd/E11882_01/server.112/e25554/sqlmodel.htm#BEIGGGFJ

  «Using UPSERT creates a new cell corresponding to that referenced on the left-hand side of the rule when the cell is absent, and the cell reference contains only positional references * qualified constants *.»

  What is going on?

  Hello

  In fact, the first query should have failed with the same error because the Digital projection is not defined anywhere in the TYPE clause (it defines only LVL, F1 and F2).

  But what happens here is that the subquery of the DOUBLE is merged into the main and constant query are used instead.
  This is confirmed by a 10053 trace:

  Final query after transformations:******* UNPARSED QUERY IS *******
  SELECT 1 "NUM","F1" "F1"
  FROM "SYS"."DUAL" "DUAL"
  MODEL
    DIMENSION BY (1 "LVL")
    MEASURES (1 "F1",1 "F2")
    UNIQUE  DIMENSION
    RULES  UPSERT  ITERATE (3)(
      UPDATE "F1"["LVL"IS ANY]=("F1"[( CURRENTV("LVL"))])+("F2"[( CURRENTV("LVL"))]))
