• Dimension to build using the SQL table and process to populate the SQL table

  I have a dimension in a cube that is manually* built by one of our power users. Now, I have to get all the information of members of this dimension in a SQL table (example: with columns... Level0, level0property, level1, level1property etc...) to use this table in the STUDIO for the responsibility of the Member.
  
  Is there any easy process to do this? Currently I am building each line manually in the SQL table and there are 1100 + members in that manually built dimension. Please advice.

• insert into the summary table of the table.

  I was wondering if there is a smart way to do it with SQL, but I'm not sure. I would like to consult you yo guys.
  
  I have a table like this

   CREATE TABLE "TEMPLE_FINANCE"."TEST" 
     (     "COLUMN1" VARCHAR2(10 BYTE), 
       "COLUMN2" VARCHAR2(10 BYTE), 
       "COLUMN3" VARCHAR2(10 BYTE), 
       "COLUMN4" VARCHAR2(10 BYTE)
     ) ;
  
  
  Insert into TEST (COLUMN1,COLUMN2,COLUMN3,COLUMN4) values ('1','2','50.00',null);
  Insert into TEST (COLUMN1,COLUMN2,COLUMN3,COLUMN4) values ('1','2','50.00',null);

  I would like to at the rate of an update and you end up with

  "COLUMN1"     "COLUMN2"     "COLUMN3"     "COLUMN4"
  "1"                  "2"          "100.00"     

  What update statement can run for this?
  I would enter in the summary of the lines based on the column 1 and column2 and get rid of repeative lines.
  I have try this insert statement, but it's bascially just adding an extra record in the table.
  

  INSERT INTO  TEST (SELECT COLUMN1, COLUMN2, SUM(COLUMN3), COLUMN4 FROM TEST GROUP BY COLUMN1, COLUMN2,COLUMN4);

  any help would be grateful.

  Hello

  I can't help but wonder if you have the best design of table for what it is, you need to do.

  The best solution would be to create a new table, using the SUM (TO_NUMBER (Column3)) and GROUP BY, and then delete the original table and rename a new one to the old name. While you're at it, change Column3 as a NUMBER and add a primary key.

  In collaboration with just the existing table, INSERT one won't work. INSERT always adds new lines. You want something that can INSERT new lines (or update some existing routes) and DELETE lines at the same time. FUSION can do it all. Here's a way to use the MERGE:

  MERGE INTO     test     dst
  USING   (
            SELECT column1, column2, column4
            ,      SUM (TO_NUMBER (column3))
                               OVER (PARTITION BY  column1, column2, column4)
                              AS column3_total
            ,      ROWID             AS r_id
            ,      MIN (ROWID) OVER (PARTITION BY  column1, column2, column4)
                                        AS min_r_id
            FROM    test
       )          src
  ON     (src.r_id     = dst.ROWID)
  WHEN MATCHED THEN UPDATE
  SET     dst.column3       = TO_CHAR ( src.column3_total
                              , 'FM9999999.00'
                          )
  DELETE
  WHERE     src.r_id     != src.min_r_id
  ;

• ListField using the hash table

  Hi guys, new here so please, be gentle.

  I was wondering if there is way to a ListField (or something similar) but using a hash instead of a vector table. I searched through the forums without success. And if it is would it be possible to display the incredible list. (List in the hash table and sort by alphabetical order, via the keys)

  The hash table structure K = String (name of player), V = object reader.

  If this can be done using a hash table, is there a way to do this using a vector. So that I could search the data structure for a players name and return the object.

  Sorry if it's confusing or vague. I'm not not used to describe my problems!

  Thank you very much for the help.

  You can also move forward and persist in the hash table, and then build an index using a few stores of SimpleSortingVector who keys in order.

  There are a lot of options... you just need to decide which is best for you.

• Use the same table queue send two different messages?

  Hello

  We have a reconciliation and an outgoing queue in our database!

  Now, we need to create another message content to send to IBM MQ series, so it's just an outgoing messages (no incoming message!)

  I was wondering if I can use the same outgoing queue table and infrastructure Message gateway to send another message charge (contect) to the IBM MQ.

  Don't you think it's possible?

  Thanks a lot for your help!

  
  

  Hello Louis,.

  first of all I didn't detect something strange or even incorrect - perfect!

  Your questions:

  > 1. have I defind is correct? "multiple_consumers => TRUE);"

  Yes, that's correct. We must define this order to use MGW.

  > 2. I failed: gv_mq_inbound_log_queue: = 'ORACLE.002 ';     part because I have not all incoming messages to oracle, I just sent messages in my case! > Is this correct?

  Yes, that's also OK. Since you're carrying data from AQ to MQ in an outgoing queue. Incoming queue would be

  the other way around. You have configured your MQ as a remote queue (sys.mgw_property ('MQ_openOptions', 16')).

  You wishes to clarify this yet once with your MQ management group if this is correct. You may not know at this stage.

  The alternative would be a local queue (value = 2066).

  You don't show the part for the queue. This should be something like:

  BEGIN

  v_message_text: = p_message_text. GETCLOBVAL().    -using the XMLTYPE as payload type

  v_text_body: = SYS. MGW_TEXT_VALUE_T (NULL, v_message_text);

  v_payload: = SYS. MGW_BASIC_MSG_T (v_header, v_text_body, NULL);

  DBMS_AQ. ENQUEUE (queue_name-online p_queue_name,

  enqueue_options-online enqueue_options,

  message_properties-online message_properties,

  payload-online v_payload,

  -Online v_msgid msgid);

  > 3. The last of them, do you think I'll reach my goal with all these codes? Is that what you think may be missing or... ?

  Yes, you will reach your goal using this code. Try it and tell me what happened.

• Issue using the ENGINE table MEMORY SUNOPSIS (high priority)

  Hi gurus,

  Hi all

  The issue has been resolved successfully.

  The solution is
  We need to change the E$ _, I have$ _, J$ _,... E_, I_ , J_... ((c'est à dire, enlever le symbole '$')) in the PHYSICAL SCHEMA of ENGINE table SUNOPSIS MEMORY according to the information provided below.

  When interfaces running and using an XML schema or file complex as the transit area, the 'Unknown token' error. This error is caused by the HSQL (2.0) updated version. This new version of HSQL requires that the names of tables that contains a dollar sign ($) are enclosed in quotes. Temporary tables (loading, integration, etc.) that are created by the knowledge Modules do not respect this requirement on the technologies of complex and HSQL records.

  To work around the problem, change the physical schema definitions to remove the dollar symbol ($) of all paintings of prefixes work. Scenarios must be regenerated with these new settings.

  It has worked well for me.

  Thank you

• problem in the form of master-detail when you use the ADF table for detail

  Hello
  
  jdev version - 11.1.2.1.0
  
  
  I create master shape detail using datacontrol drag as ADF master shape secondary Table.
  
  
  Now when I create a new line in the detail table using the key CreateInsert a new empty row created on top of the secondary table.
  
  and other show line that the previous record data based on the master.
  
  problem is I want to when I click on the createInsert button all the line of the secondary table must be empty and what line to fill two or three user then validate.
  
  
  
  Thanks in advance

  Hello

  If a secondary table has data, then createInsert adds to them. If you want to hide the existing lines, create a new instance of the View object and set the option "extract database" to "No. Rows. Use an af:switcher to change the specified table when the user clicks the createInsert button. There is some coding needed to have this use case in the ADF, but its essentially declarative. Bottom line, is that there is no option automated other than to create new lines in a separate page or dialog box if you are bothered by existing lines

• Two filters in two dimensions without constraining the fact table

  Hi all
  
  does anyone know how to avoid the factual constraint when you create a report with two filters on different dimensions?
  
  I have a fact table big with more than 10 million lines. In the starmodel is the customer of the dimension and the products. I create a filter on the customer atrribute 'Status' and set to 'active '. Now I add the "Product Type" column of the dimension 'Product' in the filter section. When I want to choose a value OBIEE executes a select statement in the fact table. So I have to wait very long to select a value. Is it possible to say OBIEE only to select the dimension table without joining the fact table?
  
  Thank you much in advance.
  
  Kind regards
  Stefan

  Use is implied.

  Create a table of facts of the DUMMY and make also implied made for this dimension column. It will solve the problem.

• Type of Dimension set using the Rules file

  Hello
  
  I tried to build a dimension (ASO) of accounts using the build parent-child and wanted to know if we can specify the dimension type "Account" to in the rules file?
  Also all the codes of the property can be given in a single column or placing them in separate columns a good practice? I need to make this hierarchy of dimension as 'dynamic '.
  
  I use the definition of dimension of the rules file option name.
  
  Thanks for your contributions!

  Yes you can do it in a rules file. In the setting dimension dialog box, go to the third tab. You can see the list of dimensions and the possibility of adding dimensions. Right-click on the desired size and then select Edit properties. Then, you can set the dimension type and dimension member properties.
  With regard to the properties. I always keep in separate columns of my source.

  I need a join_date of date value maximum for each Department. If max (join_date) has two records for each dept max (end_date) are to be considered. I used a select query

  select * from student where join_date in (select 
  max(join_date) from student group by dept);

  gives me the following result

  1     D     1/1/1920     5     8/26/1994
  1     C     1/1/1920     6     8/26/1945
  2     I     8/16/1916     9     8/26/1923

  5     I     2/10/1931     24     8/26/1962

  But I'm looking for the result that gives me only a maximum value for each column dept. First of all, it should look like to a maximum value of join_date, so two records even join_date max (end_date) are to be considered. The result should be sumthing like this

  1     D     1/1/1920     5     8/26/1994
  2     D     8/16/1916     10     8/26/1987

  Hello

  This is called a Query Top - N , and this is a way to do it:

  WITH     got_r_num     AS
  (
       SELECT     student.*
       ,     ROW_NUMBER () OVER ( PARTITION BY  dept
                                 ORDER BY          join_date     DESC
                           ,                end_date     DESC
                         )      AS r_num
       FROM    student
  )
  SELECT       dept, dep_name, join_date, years_attended, end_date
  FROM       got_r_num
  WHERE       r_num     = 1
  ORDER BY  dept
  ;
  

  Another way is similar to what you posted:

  SELECT    *
  FROM       student
  WHERE        (dept, join_date, end_date)
                 IN (
                      SELECT    dept
                 ,       MAX (join_date)
                 ,       MAX (end_date) KEEP (DENSE_RANK LAST ORDER BY join_date)
                 FROM      student
                 GROUP BY     dept
                 );
  

  I suspect that the first way (using ROW_NUMBER) will be faster.
  In addition, the ROW_NUMBER approach is guaranteed to return only 1 line by Department using the approach of GROUP BY, if there is a link on join_date and end_date then it will return all the contenders in this Department. using ROW_NUMBER, it is easy to add expressions to tie-break as much as you want, and, if there is still a tie, it will be arbirarily pick, one lines involved in the tie as #1.

  Thanks for posting the CREATE TABLE and INSERT! It is very useful.

• Error importing CSV files with "hidden" characters using the external Table

  Hi people
  
  Bit of a strange here.
  
  Well, we are accustomed to the use of the external Table method to load data from CSV files in the database, but a recent event presented us a problem.
  
  We have received some CSV files that "look like" regular CSV files, but Oracle will not load them.
  
  When we looked at the CSV using VIM on a UNIX machine, we saw the following characters 'hidden' between each regular character in the file.

  ^@

  If a string that looks like this when opened in Excel/Wordpad etc.

  "TEST","TEXT"

  Looks like this when exmained with VIM

  ^@"^@T^@E^@S^@T^@"^@,^@"^@T^@E^@X^@T^@"

  Has anyone encountered this before?
  
  Thank you very much

  Oracle 11g 11.2.0.1.0

  Hi Simon,.

  ^ @ represents the ZERO character (0x00).
  So, most likely, you have a file encoded in Unicode.

  You need to specify the character set in the record specification (and if necessary the byte order mark), for example:

  CREATE TABLE ext_table
  (
    col1 VARCHAR2(10),
    col2 VARCHAR2(10)
  )

  )
