• How to create user defined groups and users with custom permissions as only open and export in obiee 11 g?

  Hello

  I want to give as open & export to the level of permissions.

  How to create user defined groups and users with custom permissions as only open and export in obiee 11 g?

  For example, if the group permissions, inturn should reflect on the users.

  Please help me.

  Thanks in advance,

  Your question is quite broad and fuzzy then I suggest the security catalog presentation to read documentation: http://docs.oracle.com/middleware/1221/biee/BIESC/mgrgrpsusers.htm#CIHIBJGD

  And I think that you mix you two things which are managed in different places:

  ) an object as read access permissions, write, delete... which control you through the object "Permissions" dialog box

  

  

  (b) functional privileges controlled through "Manage privileges" under "Administration".

  How can I delete large groups of photos and save the ones I want to keep?

  Rickw salvation,

  You must select all the images you want to remove in now CTRL + click in Windows and command-click on Mac.

  Once this is done, you can press the delete button to delete the catalog.

  It will also give you the option to delete the computer as well.

• How to create a validation "not null" unique for all elements in a page?

  Hello world
  
  How to create a validation "not null" unique for all elements in a page? I love textfields. Rather than create "not null" validation for each article, I would like to create a single validation control that will be used
  
  Thanks and greetings
  Umer

  Bob, like u said I did the following:

  (1) less to create a button, there are 9 elements, and for each item, I put in the light of 'yes '.
  (2) under the button Delete, there is 1 point and have in light of the 'Yes' for the item
  (3) validation of the page defined for the 9 items under 'create a button' and put it to fire when 'create' button clicked
  (4) the page validation set for 1 number under 'remove' button and put it on fire when "delete" button clicked

  now, when I click on the 'create' button it shows same for the item under the "Delete" button that's a required element

  Sorry, I do not see this note. The required model will not work, there is no way to attach it to the button.

  The best solution is that the answer only a few answers to the top

  Create 2 validations page type as a PL/SQL with code

  1st validation
  
  :P1_ITEM1 IS NOT NULL and :P1_ITEM2 IS NOT NULL ...... and :P1_ITEM9 IS NOT NULL  include all 9 items
  
  Set the When Button Pressed to the CREATE button
  
  2nd validation
  
  :P1_ITEM10 IS NOT NULL
  
  Set the When Button Pressed to the DELETE button
  

  I think that this will be the best way to do it.

• How to combine the large number of tables of pair key / value in a single table?

  I have a pair key / value tables of 250 + with the following features
  
  (1) keys are unique within a table but may or may not be unique in the set of tables
  (2) each table has about 2 million lines
  
  What is the best way to create a single table with all unique key-values of all these paintings? The following two queries work up to about 150 + tables
  

  with
    t1 as ( select 1 as key, 'a1' as val from dual union all
            select 2 as key, 'a1' as val from dual union all
            select 3 as key, 'a2' as val from dual )
  , t2 as ( select 2 as key, 'b1' as val from dual union all
            select 3 as key, 'b2' as val from dual union all
            select 4 as key, 'b3' as val from dual )
  , t3 as ( select 1 as key, 'c1' as val from dual union all
            select 3 as key, 'c1' as val from dual union all
            select 5 as key, 'c2' as val from dual )
  select coalesce(t1.key, t2.key, t3.key) as key
  ,      max(t1.val) as val1
  ,      max(t2.val) as val2
  ,      max(t3.val) as val3
  from t1
  full join t2 on ( t1.key = t2.key )
  full join t3 on ( t2.key = t3.key )
  group by coalesce(t1.key, t2.key, t3.key)
  /
  
  with
    master as ( select rownum as key from dual connect by level <= 5 )
  , t1 as ( select 1 as key, 'a1' as val from dual union all
            select 2 as key, 'a1' as val from dual union all
            select 3 as key, 'a2' as val from dual )
  , t2 as ( select 2 as key, 'b1' as val from dual union all
            select 3 as key, 'b2' as val from dual union all
            select 4 as key, 'b3' as val from dual )
  , t3 as ( select 1 as key, 'c1' as val from dual union all
            select 3 as key, 'c1' as val from dual union all
            select 5 as key, 'c2' as val from dual )

  ,      t1.val as val1
  ,      t2.val as val2
  ,      t3.val as val3
  from master m
  left join t1 on ( t1.key = m.key )
  left join t2 on ( t2.key = m.key )
  left join t3 on ( t3.key = m.key )
  /

  A couple of questions, then a possible solution.

  Why the hell you have 250 + tables pair key / value?

  Why the hell you want to group them in a table containing one row per key?

  You could do a pivot of all the tables, not part. something like:

  with
    t1 as ( select 1 as key, 'a1' as val from dual union all
            select 2 as key, 'a1' as val from dual union all
            select 3 as key, 'a2' as val from dual )
  , t2 as ( select 2 as key, 'b1' as val from dual union all
            select 3 as key, 'b2' as val from dual union all
            select 4 as key, 'b3' as val from dual )
  , t3 as ( select 1 as key, 'c1' as val from dual union all
            select 3 as key, 'c1' as val from dual union all
            select 5 as key, 'c2' as val from dual )
  select key, max(t1val), max(t2val), max(t3val)
  FROM (select key, val t1val, null t2val, null t3val
        from t1
        union all
        select key, null, val, null
        from t2
        union all
        select key, null, null, val
        from t3)
  group by key
  

  If you can do it in a single query, Union all 250 + tables, you don't need to worry about chaining or migration. It may be necessary to do this in a few passes, depending on the resources available on your server. If so, I would be inclined to first create the table, with a larger than normal free percent, making the first game as a right inset and other pass or past as a merger.

  Another solution might be to use the approach above, but limit the range of keys with each pass. So pass we would have a like predicate when the key between 1 and 10 in every branch of the union, pass 2 would have key between 11 and 20, etc. In this way, everything would be straight inserts.

  That said, I'm going back to my second question above, why the hell you want or need to do that? What is the company you want to solve. There could be a much better way to meet the requirement.

• In Windows 8, how to create a contact group?

  Cannot find out how to create a contact in post group or people in the new Windows 8. It was easy in Vista.

  I just thought of it.   Rather than use the tile "mail" on the start page to access your gmail account, use the tile "internet explore ' to access Google.   Google, search the gmail registration page.    Sign in as usual and you can then click on the "applications" button in the upper right and click on the "mail" symbol and it takes you to the old access gmail... so looks like he did for me on my Windows XP.

  I just did this, to make it work without a doubt.

• How to create the column of the table for long-form Master detail relationship

  Apex 4.1

  Oracle 11g

  I created a form master detail and see the main table hotel_list and table hotel_mapping as detailed below.

  Hotel_list

  ID HOTEL_NAME

  1 Holiday Inn

  Hotel Hilton 2

  Hotel_mapping

  ID HOTEL_NAME MAPPING_NAME

  1 Inn Holiday Inn Select hotel

  2 holiday hotel Holiday Inn Select

  3 hotel Holiday Inn Holiday Inn Hotel

  4 Hilton Hotel Hilton Hotel chain

  Hotel Hilton 5 HiltonHotel

  Table Hotel_name Hotel_list is a linked table Hotel_mapping

  When I add a line to the Hotel_mapping table for the selected row in the hotel_list table, mapping_name of column is null, therefore impossible to create the relationship between the main table and the secondary table.

  I would like to know, how to create the relationship?

  Thank you very much

  Best regards

  Yong Huang,

  simple step see creating a form detailed master with APEX - Assistant Master retail

  and check how to maintain the relationship between two tables,

  simple return the packaged application «Sample of Masters details»

  and try to understand this concept...

  In your example, use Hotel_list.ID as a foreign key in the table Hotel_mapping

  and maintain the relationship with the column ID...

  and choose the display type of the column Hotel_list.ID in table Hotel_mapping as List(Query Based LOV) select.

  otherwise the best way is to create sample on oracle.apex.com

  I hope this helps...

  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?

• How to create an OID group when a group of IOM is created?

  Hello
  
  How can we create an OID group when a group of IOM is created?
  
  An administrator creates (s) and put them under the ABC organization.
  
  The administrator adds the user to IOM group XYZ and the user should eventually be added to the corresponding OID XYZ group.
  
  Is it possible to have the IOM to create a group in OID when the same group is created in the IOM?
  
  Thank you
  
  Khanh

  You should be able to trigger just the task that creates the OID group, unless it takes parameters indirectly (i.e. giving the task the organization name and it will read the name of the Group of the Organization of the IOM).

  Also, is not very difficult to do with custom code of JNDI. I have a bit of AD which should work well on OID. Contact me through LinkedIn if you want the code.

  Best regards

• How to create a grid with the tables and Boolean values?

  As part of a larger project, I'm trying to create a Subvi, which will allow me to spend a "cursor" in a 3 x 3 matrix.

  It should be 2 Boolean inputs, one for move them down in the table and the other to move them to the right. Once reached the edge of the table, the "cursor" will start back at the beginning.

  I have a vague idea of a table to 2 dimensions with LED. Once 'down' has been selected, the corresponding light to (0,0), light (0.1). Goes the same for the button 'right '. When 'down' is pressed (0.2), the LED should turn off, and LED (0,0) must light up.

  I'm sure it has something to do with the initialization of the tables, but I can't seem to find the right way to do it.

  Any help is much appreciated. Thank you!

  Your array is always empty.  Look at the detailed help for the function page replace table subset.  He says that the function has no effect if the specified index refers to a location outside the table.

  What you see on the Panel is only a view and has nothing to do with what is in the table.
