• How to get the column number

  Hi all,

  I'm sorry to ask this question because I found 2 different answers, tried without result. So before you go crazy, I prefer to ask!

  Thus given mySelection = app.selection [0], how is possible to get the column's selection?

  I tried app.selection [0] .parentTextFrames [0].characters.itemByRange (0, x)

  with x being app.selection [0] .index.

  but then I'm stuck as if I add ".textColumns", I get an error

  I explored the second way using app.selection [0].textColumns.item (1).insertionPoints.item (1), but once I'm stuck again.

  As a beginner I don't understand why there is no simple built-in function to call in order to obtain such a result of base

  Any help would be appreciated

  Thank you

  Okay here goes,

  For and only for the linked text frames.

  // For and only for linked text frames.
  // Warning
  // The Good: This will PROBABLY work for you
  // The Bad :THIS IS A REALLY PRIMITIVE METHOD
  // The Ugly: It could fail in COUNTLESS cases
  // Here goes......
  
  var mySelection, textFrame, parentPage, c;
  mySelection = app.selection[0];
  textFrame = mySelection.parentTextFrames[0];
  parentPage = textFrame.parentPage;
  c = 0;
  while(textFrame && textFrame.parentPage === parentPage){
      textFrame = textFrame.previousTextFrame;
      c++;
  }
  
  alert('Column number: ' + c);
  

  Now with regard to the issue of the image columns bound text compared to the blocks of text with multiple columns of text or span. Depends on what you're trying to achieve with your workflow.

  The scripts are around written by me and others who convert multicolumn text executives to related texts related and vice versa.

  If you want to know which is more appropriate you can use with your workflow, then I suggest the regular ID forum.

• How to get the column provided out of the Oracle Data Miner?

  Hi all!

  I use Oracle Data Miner provided with Oracle SQL Developer to predict the loss of customers. If I plan on the table column lets say X (as a target column) of table say T, so how can I get the corresponding values under my model?

  Here is the simplified model for the reference.

  Thanks in advance!

  

  Hello

  Simply connect a node that accepts data to the node to apply it.

  For example, if you want to create a view or table table using the prediction of outputs generated by the node to apply it, and then add a Create Table node and connect the node to apply it.

  For more information, try the Oracle by example tutorials for ODMr.

  You must use the node apply Publisher to revise prediction outputs models to generate as well as the additional columns to include, for example columns id.

  There are a set of predictor columns added by default that may be acceptable.

• Get the columns returned by the query without running

  I have a table that stores SELECT queries in a column. I developed a .net application where the interesting thing for the user is what columns of the following SELECT statement returns. Currently, I load the sql as an OracleCommand object CommandText and fill a DataTable using an OracleDataAdapter object. I then read the names of the columns of the table filled. The data is not fully used. Requests can take up to 15 seconds to run. Because I do not used the data, I was hoping to eliminate the actual recovery of data and reduce the time needed to retrieve the records. Is it possible to analyze the statement for the colunm names with it makes the request for enforcement? Thank you.

  I imagine that there is a way you can search in the data dictionary, but you can also try to add 'WHERE 1 = 0' If you want the metadata.

  It will be useful,

• [ADF, JDev12.1.3] How to get the column headers, request of VO and VO bind vars used by an af:table?

  Hallo,

  I want to create a method that takes as a parameter the id of an af:table (used to display the search results) and returns:

  • the column headings of the af: table
  • Visible property (true/false) of the columns af:table
  • the actual query of the VO instance used to create the af: table
  • the values of real bind variables passed to the query of the instance of VO

  I would like to create a servlet which takes the parameters reruns the query and returns a report Excel/PDF file that contains exactly the same columns and same of the af records: table.

  I'm a little confused on who use the code to achieve this... you kindly help me?

  I did a similar qustion here Re: [ADF, JDev12.1.3] how to export an af:table to Excel in an ADF Essentials application? but then I guessed that it was preferable to create a new thread.

  Thank you

  For this, you can use this type of code

  Context LocaleContext = _adfTableBinding.getLocaleContext ();

  for (attr AttributeDef: attributeDef) {}

  Label As String = attr.getUIHelper () .getLabel (context);

  _logger.info ("Attritbute name:" + attr.getName () + "column name:" + attr.getColumnName () + "Col4Query name:" + attr.getColumnNameForQuery () +)

  "Name:"+ label);

  }

  which produces this output

• How can I get the columns-by-side?

  http://www.Adobe.com/devnet/Dreamweaver/articles/first_website_pt2_08.html

  In the creation of your first tutorial of Web site (see link) I can not understand how to recover the columns side by side are being stacked. I went on the indications of the tutorial at least five times. What I am doing wrong in coding?   Here is a picture of my screen:

  Here is a screenshot of how the columns should be stacked (from the tutorial):

  

  Take a look at where you graduate #center_column in the html code of the page. You have this:

  where it should be

  Because a class called 'center_column' has not been defined (somehow), it belongs to the following line.

  I saw your styles for all three columns, as IDs.

• Select the lines with the maximum value for a date where another column is different from 0

  Hello

  I need to write a query on a table (called DEPRECIATION) that returns only the rows whose date maximum (PERENDDAT_0 column) for a specific record (identified by AASREF_0), and where the other column in the table called DPRBAS_0 is different from 0.

  If DPRBAS_0 is equal to 0 in all the lines of a specific record, then return the line with date maximum (PERENDDAT_0 column).

  To be clearer, I give the following example:

  Suppose we have the following data in the table of DEPRECIATION:

  AASREF_0	PERENDDAT_0	DPRBAS_0
  I20110010743	31/12/2015	0
  I20110010743	31/12/2014	0
  I20110010743	31/12/2013	0
  I20110010856	12/31/2016	0
  I20110010856	31/12/2015	0
  I20110010856	31/12/2014	332
  I20140012238	12/31/2016	445
  I20140012238	31/12/2015	445
  I20140012238	31/12/2014	0

  The query must return only the following lines:

  AASREF_0	PERENDDAT_0	DPRBAS_0
  I20110010743	31/12/2015	0
  I20110010856	31/12/2014	332
  I20140012238	12/31/2016	445

  Thanks a lot for your help!

• GET THE HTTP REQUEST PARAMETERS

  Hello

  How can I send three parameters through GET on my server, I need to send three sttrings generated in my application on the server.

  I've tried with network application of Pentecost without success, demand will, but parameters never arrive

  QNetworkAccessManager * Manager = new QNetworkAccessManager (this);
  Application of QNetworkRequest (QUrl ("http://server.php"));
  request.setRawHeader ("to", "email");
  request.setRawHeader ("title", "hello");
  request.setRawHeader ("msg", "text messages");

  Manager-> get (request);

  Thank you

  You could add the strings as GET parameters to the URL:

  QUrl ("http://server.php?to=email&title=hello&msg=text+msg");

  But I think you should PUT these fields to the server because the URL has a maximum length:

  QByteArray data;

  Data.Append ("[email protected] &"); ")

  Data.Append ("title = Hello World &"); ")

  Data.Append ("msg = Hello World! Are you okay? ») ;

  Manager-> post (request, data);

  I have it wrapped in a method that takes QMap as parameter and returns QByteArray, because it's quite annoying to keep in mind to add '&' between each pair of key / value.

• Add/change the columns of data type (scripting)

  Hello

  I am writing a script to add default columns and their values in tables. So far, for me, it is possible to add columns to an existing table in the model.

  Then, I want to add value to the data type. I discovered there is a method called getDataType(). So far, I have not found the "setter; for this property.

  Like other scripts, I started by creating a table with columns, and then using the API to read the values.

  A simplified version of my code:

  get the columns of table

  myTab var = model.getTableSet () .getByName ("T_POSITIONS");

  colArray = myTab.getElementsCollection () .toArray ();

  loop through columns

  for (i = 0; i < colArray.length; i ++) {}

  the type of var data = colArray [i] .getDataType ();

  model.getAppView () .log (colArray [i] + "a datatype" + dataType);

  colArray [i] .setDataType ("VARCHAR2 (1)");

  }

  An error occurs when I want to run this script: could not find setDataType function in the object ID.

  I can't find the right method to add/change the datatype property.

  Any information would be appreciated.

  Thanks in advance.

  Apologies - I have managed to reproduce the original problem in 12.1.0.2.

  The problem with ATTR column names is that you use a local collection declared in a package.

  You need a SQL type.

  But does not change my position when it comes to a sensible direction to go.
