• How to revoke the SELECT on a table for a specific user?

  Environment:
  
  SQL * 3.1 on Windows XP Pro SP3 Developer to connect to Oracle 11.2.0.3 EE on Solaris 10.5.
  
  I have table T with SELECTION privilege granted on this issue both a role and a specific user.
  
  I am using SQL * Developer to revoke the privilege SELECT on this table of the individual user and leave the role.
  
  I can see how to revoke the role by right-clicking on the table and goes to the privileges-> revoke but I can't find where to choose a specific user to revoke of.
  
  Any help is greatly appreciated!

  Hi Gary,.

  You are probably aware of the SQL syntax of base to make grant and revoke of SQL * more or the SQL Developer Worksheet:

  grant select on .T to ;
  revoke select on .T from ;
  

  To reach the equivalent to revoking of SQL Developer Connection Navigator...
  1. open the connection for
  2 expand the Tables node, and then open the object for table T browser.
  3. click on the grants tab and then, in its toolbar, select Actions->-> Revoke privileges
  4. Select in the drop-down list of the dialog box to remove user Action.
  5 shuttle privilege SELECT from the right back to the left, and then click apply.

  One would expect to be able to do the same thing from say the node under the node for the use of the SYSTEM for other users, but this isn't the case.

  Hope this helps,

• Is to select a view that is more effective than the selection of multiple tables

  Hi here is the problem
  
  Lets say I created a view of 2 tables (person and information). both have an ID column
  

  create view table_view (age,name,status,id) as
  select a.age, a.name, b.status, b.id
  from person a, info.b
  where a.id=b.id

  If I want to select a range of values of these 2 tables including the following queries would be more effective.
  

  select a.age, a.name, b.status, b.id
  from person a, info.b
  where a.id=b.id
  and a.id <1000

  select age, name, status, id
  from table_view
  where  id <1000

  No, this is not true.

  A view is just a request. As any issue, you must run from the SQLPlus command line or any client application. The only difference is that the text of the query is saved in the database so that you do not have to re - enter type this in your query.

  Once the request is submitted the optimizer doesn't bother if it comes from a view or a user by entering the text of the entire query again on the SQLPlus command line.

      var row_id = pThis.id.substr(4);
      if (row_val == 'N') {

• Writing table to the selected line in the table table

  Hello

  im stuck on trying to display a line of data that I took from an excel file.

  display just the data on an array of table has no problem, BUT when I use the Index table and Replace the function subset of table, no data out.

  so, Table3 has the data I want but Table2 have no data at all.

  IM using the Index table and the function Replace subset of table to allow me to SELECT the LINE I want to be shown on

  any idea?

  

  Hey!

  Try this...

  I use the array function to remodel to change the extracted Excel from 2D to 1 d. Then you can replace all right in your table.

• Returns the selected table column header

  I don't know there is probably a way to do this.  But I have not yet found.

  I am building an application that will act as a sort of "universal" reports generator for a MySQL database tables.

  At startup, a drop-down list box is filled with the names of tables in the database.  When the user selects one of these tables, the column names are taken from the base and used to fill the column headers for the table of LabVIEW.

  The idea is that the user can select this column and enter the constraints of filter in a text box.  These constraints will then be added to the WHERE statement for this column.

  So far I've been able to find a way to return the Active cell or a selection of cells, when the user clicks on the actual data of the table.

  Is there a direct way to retrun a selected in LabVIEW column header value?

  I am dreaming that there may be some sort of workaround using transparent controls over the headers.  But because different tables will have a different number of columns that the user defines the width, I'm not really sure that it will work more.

  If you the editable headers, this allows Active cells specify that your column is - 1 column selected active line is the selected column. You may need to use the mouse down? to filter the possibility for the user to change the right column headings.

• ADF table selected displayRow does not display the selected line

  Hello

  JDev 11.1.2.4

  I have a table with selection enabled and displayRow property the value selected. In the workflow, I have an ExecuteWithParams activity, and then a method activity that restores the current iterator of the line. Finally the activity view that displays the table.

  Restore the current line with key

  Iterator DCIteratorBinding = ADFUtils.findIterator ("MyIterator");

  iterator.setCurrentRowWithKey (currentKey); currentKey is a string

  The question I have is that the current line is properly restored, but the table does not display the page of "range" of the current line while the displayRow is the selected value. My table has 500 rows, the table displays the top 25 while the current line is the 500th line. I expect the table to display the line 475 to 500 line.

  What I am doing wrong?

  Thank you

  You can save the index lines before executing your method and then set the iterator to this index.

  The technique is described in this blog https://tompeez.wordpress.com/2016/02/12/naviagting-an-aftable-in-pagination-mode-from-a-bean/

• How to manage the selection with the box in a table

  Hello

  
  

  JDev 11.1.2.4

  I have a table with an attribute of EO/VO, transitional to manage the selection. This attribute is displayed as a check box. The user makes a selection by clicking on the checkbox. Then, the user clicks on a button that displays a pop-up window. Inside of this pop-up window, that user can create, insert, delete, or update values in a table based on an other EO/VO.

  When the user clicks OK, the pop-up window is closed, then the data is committed.

  When the user clicks Cancel, the popup is closed and the changed data are ignored. To remove the data, I call a Rollback. It works fine, but all the transitory values are lost which is correct because of the discount after the cancellation.

  It's a problem because the user must be able to open the pop-up window several times with the same selection. This means that the restoration is not appropriate in this case.

  How to ignore data edited inside the pop-up window and keep the selection?

  Thank you

  You can try to put the popup in his own taskflow and define a backup point before entering the taskflow. When the user cancel the editing restore you to previous backup. This should dispel the changes.

  Or you save the selected rowkeys, call rollback and backward selection later.

  Hello

  We have an obligation to engage only the selected lines in a table. All lines in the table must be modifiable. There should be a 'Save' button in a column that has to save the selected line when you click it.

  Could you please share your comments/suggestions.

  Maybe you can add the attribute transitional to EO as an indicator whether the line should be validated in db or not, override EOImpl.doDML () and skip super.doDML () If this attribute is not set.

  Any idea?
  

  Well, you can use selectionListener to set the selected line to a variable of bean (but this bean must be in extended view or some superiors)

• Select the data in a table and update in another table

  Dear experts,

  create the table TB_ENCRYPT

  INSERT INTO TB_ENCRYPT VALUES(1,'HJUVHDUIFBSDGVU');

  SELECT * FROM TB_ENCRYPT;

  Insert users

  values (2, 456 #')

  Select * from users;

  1 123 #.

  # 2 456

  I want to select the data KEY for table TB_ENCRYPT column and update in the column of tables for the respective key user password

  TB_ENCRYPT table contains only a single key value. Comparing this key, I want to update the old value of the key to the new value.

  For encryption and decryption I followed the java class method.no is worried about that.

  create or replace

  PACKAGE PCK_ENC AUTHID CURRENT_USER AS

  FUNCTION DECRYPT (VARCHAR arg0, arg1 VARCHAR) AS VARCHAR BACK LANGUAGE JAVA NAME 'Encrclass.decrypt (java.lang.String, java.lang.String) return java.lang.String ';

  FUNCTION ENCRYPT (VARCHAR arg0, arg1 VARCHAR) AS VARCHAR BACK LANGUAGE JAVA NAME 'Encrclass.encrypt (java.lang.String, java.lang.String) return java.lang.String ';

  SELECT PCK_ENC. ENCRYPT('1234','HJUVHDUIFBSDGVU') FROM DUAL;

  HERE,

  1234 - is the password of the users table column data

  HJUVHDUIFBSDGVU - represents the key of table TB_ENCRYPT column data.

  Comparing this key, I want to update the old value of the key to the new value.

  I tried with this method

  declare

  cursor c1 is

  Select the key

  of TB_ENCRYPT

  where id = 1

  update the id;

  Start

  for c1_rec looping c1

  update users

  password is PCK_ENC. Encrypt (Password, Key)

  the location being c1;

  commit;

  end loop;

  end;

  /

  Help, please

  You can use the MERGE statement.

  merge into users
  using tb_encrypt
     on (id = userid)
    when matched then
        update set password = PCK_ENC.ENCRYPT(password,key);
  

  And why you encrypt your password. This isn't a good idea. Just password hash.
