• How to dynamically change the names of columns LOV

  Hello

  I use JDeveloper 11.1.1.4

  I have only one requirement, while I need to change the names of columns in the list of values dynamically.

  How can I achieve it.

  Please help me.

  Hello

  > But I want to change the column names 'ID' and 'Name' dynamically.

  Based on what? Condition? If Yes, have you tried to set the text for the label as an expression? If not based on the condition, you can also expose the VO to Java Impl and need a way to get the attribute and change its label.

• Retrieves the name of the variable

  Hello

  I'm trying to change the OpenG changed? Subvi (see below) so that he will write the new value of the variable sent to 'Variant' if changed on the disk (using the following config VI). To do this, I need to somehow extract the variable name of the variable (any type) which was connected to the entrance of variant of the changed? Sub - VI by VI calling so that I can use it as a key name. Is this possible? This information is still transmitted to the Subvi?

  

  If you use openg, there is a "Get the name of data" function that retrieves the name of the data passed in the Variant.

  Renaming of files in virtual machine using Cold Storage Migration

  Virtual machine files can be renamed on the fly when cold Migration is initiated from the vSphere Client, only documents of the virtual machine are renowned.

  To rename the files:

  Log on to the VMware vSphere Client.

  Locate the virtual machine in your inventory to the host.

  Right-click the virtual machine, and then click Rename.

  Change the name of the virtual machine as required.

  Perform a cold migration to a new virtual machine data store.

  For more information, see:

  For ESXi/ESX 4.x, see Migration cold in the Guide of Administration of vSphere Datacenter.

  For ESXi/ESX 3.5, see Migration cold in basic management Guide.

  When the migration is complete, the files of the virtual machine, the name of the virtual machine configured in step 4.

  Note: If a virtual directory already exists on the data store with the same name, then the virtual target machine is placed in a new directory with annexed _1.

• ORE: the names of columns not valid cost.matrix

  I'm trying to use the method odmDT with application costs customized as follows:

  > dt.mod = ore.odmDT (default ~.,credit_train,max.depth=20,cost.matrix=matrix(c(0,1,4,0),nrow=2)

  but I get the error:

  Error in ore.odmDT (default ~., credit_train, max.depth = 20, cost.matrix = error_cost):

  ORE: the names of columns not valid cost.matrix

  I can't find any documentation anywhere on how exactly this cost matrix must be specified.

  Any help would be appreciated

  The value for cost.matrix currently requires a data structure object. The following examples using the NARROW data successfully pass a frame of data for the value of cost.matrix:

  R > NARROW.costs.gender<- data.frame(actual_target_value="">

  PREDICTED_TARGET_VALUE = c("M","M","F","F"),

  COST = c (0.25, 0.75, 0.0, 0.0))

  R > NARROW.costs.class<- data.frame(actual_target_value="">

  PREDICTED_TARGET_VALUE = c (0,0,1,1),

  COST = c (0.25, 0.75, 0.0, 0.0))

  R > dt.mod1<- ore.odmdt(gender="" ~="" .,="" narrow,="" cost.matrix="">

  Summary (DT. MOD1)

  R > dt.mod2<- ore.odmdt(class="" ~="" .,="" narrow,="" cost.matrix="">

  Summary (DT. MOD2)

  I filed a bug so this behavior can be evaluated for a future release of Oracle Enterprise R.

• return the names of columns which line values are not null.

  Hi I m a new db admin guy, and I need a sql script that should return the names of columns of the given table. and the returned column must be the value (fyi - if the column contains the value null column name would not come to the o/p of sql).
  Exmple:
  name of the table - A
  fresh status s.no name brand
  1 null aa 45P
  paid 2 null bb 30
  3 cc paid 35P
  
  (FYI - 1) if I give the table name (A) and s. n. (2) o/p should be - name, mark.
  (2) if I give the status of tablename (A) and s. n (1) the o/p should be - name, brand.
  
  Thank you

  BTW,
  The previous solution is for all values of the column, if you want a specific line, you can add it in where clause.
  I mean in your example, it you look like:

  SET serveroutput on;
  
  DECLARE
     l_cnt          NUMBER;
     l_str          VARCHAR2 (255) := '';
     l_table_name   VARCHAR2 (255) := 'YOUR_TABLE_NAME';
     l_col_cond     VARCHAR2 (255) := 'S_NO';
     l_val          NUMBER         := 1;
  
     CURSOR c_col
     IS
        SELECT column_name
          FROM user_tab_columns
         WHERE table_name = l_table_name;
  BEGIN
     FOR i IN c_col
     LOOP
        EXECUTE IMMEDIATE    'SELECT COUNT ('
                          || i.column_name
                          || ') FROM '
                          || l_table_name
                          || ' WHERE '
                          || l_col_cond
                          || ' = '
                          || l_val
                     INTO l_cnt;
  
        l_str := l_str || CASE
                    WHEN l_cnt = 0
                       THEN ''
                    ELSE i.column_name
                 END || ',';
     END LOOP;
  
     l_str := SUBSTR (l_str, 1, LENGTH (l_str) - 1);
     DBMS_OUTPUT.put_line (l_str);
  END;

• change the names of columns in the automatic process line fetch, edit the code

  Hello
  
  I created the master detailed form of two tables, and then I changed one of the names of columns in the table which is the detail.
  
  of course the extraction process could not recognize the name of this column (as it is no longer exist), so I need to change the column name in the query of in the current name.
  
  Ditto for line process transformation, to insert a new line.
  
  I guess it's easy, but I don't know where to find the ASR process query request,
  suggestions please!
  
  Kind regards.

  Hello:

  The detail rows are rendered in tabular form. This tabular presentation is implemented in a region of "report". You can change the query for the report region explain the column names.

• Need to retrieve the text of a URL and store in a variable

  Looking for advice here, I can do this in PHP, but I'm too new to CF doesn't know it yet. To spend of PHP to the CF would mean sending these variables in the URL of the web that I want to avoid.
  
  Basically I have a precompiled java module I should use referring a Y or N to verify authentication.
  I need to create the next scenerio:
  
  Display with the username and password form;
  Enter the name of the user as user name and password as password
  From the screen of the http:/intranet/servlet/WebLogin URL, get Y or N? UserID = XXX & Password = YYY
  Store the results of the verification as a global variable
  
  My attempt of CF:
  < cfform = "loginform" action = "http:/intranet/servlet/WebLogin" name
  method = "Get" >
  < table >
  < b >
  user name < td >: < table >
  < td > < cfinput type = "text" name = "UserID" required = "yes".
  message = "a user name is required" > < table >
  < /tr >
  < b >
  password < td >: < table >
  < td > < cfinput type = "password" name = "Password" required = "yes".
  message = "a password is required" > < table >
  < /tr >
  < /table >
  < br >
  < input type = "submit" value = "Log In" >
  < / cfform >
  
  -This code works to redirect the display URL displays Y or N, but how can I not enter the result and store =)
  
  
  : My PHP code to do this (works completely)
  <? PHP
  
  $url = ' http:/intranet/servlet/WebLogin? UserID = XXX & Password = YYY';
  $html = file_get_contents() ($url);
  If (preg_match ('/ Y /', $html, $matches))
  {
  echo "success."
  }
  on the other
  {
  ECHO 'no success ';
  }
  ? >
  
  
  Thank you all

  Galloping gargoyles! There are so many things wrong here!

  Anyway, if you're stuck with this approach, you will need to use cfhttp to get the result.

  Something like the attached code should help you get started.
