• Read data from the Table and load it into the csv file

  Hello

  I would like to read a table (select * from employees) and load the data into a csv file.

  What methods are available?

  Records will be at high volume.

  Thank you

  If it is to do a lot, use APEX.

  Create a new page with an interactive report based on the SQL code you want. When you go to download Excel, it is actually a CSV file.

  If it is large, you may need to go on the FILE_UTL road.

  If it is only once, use an interface such as SQL tool * or SQL * Developer.

  If it's a learning experience, you must do all three.

• Export data from several tables

  Hello

  I use the Data Export utility in SQL Developer 4.0.1. There is an option to choose a list of tables I want to understand, however in my case, I can get the list of tables by running a query against the USER_TABLES and applying some NOT LIKE filters. How to move this list to the export utility.

  Is it possible to do so.

  for example

  SELECT table_name 
  from user_tables
  WHERE NOT (table_name LIKE 'DOD%' OR table_name LIKE 'DAY%' OR table_name LIKE '%_HIST');
  

  Whatever the result I get is a list of the tables, that I need to export.

  Kind regards

  Vikram R

  You can not.

  But you can add these tables to a cart (see view > Cart) and passing to the export utility.

• Reading data from a Table by using the loop

  I have a dynamic array within the PDF form. I want to loop through the rows in the table and read the contents of the cell. I successfully get the number of rows in the table. But impossible to read the values in the cells. I put control TextField (txtName) editable in every cell and trying to read its value.

  screenshot is below.

  

  I use the code is:

   form1.Page1.Subform1.btnReadTable::click - (JavaScript, client)
  
  var rowCount = MyTable._Row1.count;
  app.alert("Row Count: " + rowCount);
  var i = 0;
  
  for(i=0 ; i<rowCount ; i++)
  {
      //app.alert(MyTable.Row1[i].txtName.rawValue); // NOT WORKING
      
      app.alert(MyTable.Row1.txtName.rawValue); // WORKING, But just giving the value for the first row.
  }
  

  Please tell me how can I get the value of each name in all ranks by making a loop.

  Thanks in advance.

  Hi, Afonso,

  You must resolve the node for the particular case of i. The syntax is:

  xfa.resolveNode("MyTable.Row1[" + i  + "].txtName").rawValue;
  

  Here there is an example that will show you the loop in action:

• Getting data from several tables

  Hello
  
  I started a few days working with Oracle TopLink, and since yesterday, I came across a problem that I can not find a solution, so I hope that someone will direct me in the right direction with this one... I'm using the tutorial provided by Oracle [http://www.oracle.com/technology/products/ias/toplink/doc/11110/tutorial/index.htm].
  
  Assuming I want to get the most effective possible , the following data (* only * these data): first_name_of_employee, last_name_of_employee, number_of_phones_of_employee.
  The Employee and phone tables are involved, table phone has an EMP_ID field that points to the field of the employee EMP_ID. How could I get such data for all employees? The first two pieces of data are pretty easy to get, but get one final turned out to be more difficult than I imagined...
  
  Any help will be most appreciated.
  
  Thank you
  Vlad

  You can probably use a ReportQuery and Expressions for this query. In TopLink you can do something you can do in JPQL using Expressions, like our support JPQL uses Expressions. To get the number of phones, you can use a count() on the id of the employee's phone with a groupBy to id of the employee. Get back the name and the name can be tricky depending on your database because I think that you can select return values that groupBy, you might try grouping by first and last name as well.

  that is something like:
  The ExpressionBuilder builder = new ExpressionBuilder();
  Query ReportQuery = new ReportQuery (Builder, Employee.class);
  query.addAttribute ("firstName");
  query.addAttribute ("lastName");
  query.addCount (builder.anyOf("phones").get ("id"));
  query.addGrouping ("id");
  query.addGrouping ("firstName");
  query.addGrouping ("lastName");

• Read data from table of $ E and insert in the staging table

  Hi all
  
  I'm new on ODI. I need your help to understand how to read data from a table ' E$ "and insert in an intermediate table.
  
  Scenario:
  
  The name of two columns, in a flat file, the employee and the employee id must be loaded into a data EMPstore +. A check constraint is added so that the data with the employee names in capital letters only to load in the data store. Check the command is set to the static movement . Right-click on the data store, select control , then check. The lines that have violated the check constraint are kept in E$ _EMP+ table.
  
  Problem:
  
  Problem is I want to read the data in the table E$ _EMP+ and transform in capital letters in the name of the employee and move the corrected data of E$ _EMP+ EMP+. Please advise me on how to automatically manage the 'soft' exceptions in ODI.
  
  Thank you

  If I understand, you want to change the columns in the tables of $ E and then load into the target.

  Now, if you notice how ODI recycles the error, there is an incremental update to the target using the E table $ after he filled the I$ table.

  I think you can do the same thing by creating an interface using the table of $ E as source and implement the business logic in this interface to fill the target.

• read data from xlsx file

  How to read data from an Excel 2010 worksheet with the .xlsx extension?  The data I want, it's on one of the 10 tabs in the file, I have to choose which programmatically.  I have the Report Generation Toolkit for LV2012, but all the screws that come with it seem to focus around writing data to a spreadsheet Excel and make charts and whatnot.  I want to * read * an Excel worksheet.  Seeking answers led to many 'Open it and save it as tab delimited text', which I can't do because I need data from different tabs, and because this file is quite dynamic with many users opening and adding several times.  In order to save the tab I want as a tab delimited text file per programming, I'm back a square, how to open it?

  My solution would ideally fill in the blanks of: spreadsheet.xlsx---> _---> 2 or 3D data table.

• Read data from APEX_ITEM

  Hi all
  
  I searched the forums, and unfortunately I have no idea on how to go on the following.
  
  I have the following SQL report created with APEX_ITEM. SELECT_LIST-
  
  > select id, questions, APEX_ITEM. SELECT_LIST (p_idx = > 1, p_value = > '- Select Rating-', p_list_values = > 1, 1, 3, 3, 5, 5', p_attributes is > "style =" "color: Black;"', p_show_null = > 'YES', p_null_value = > NULL, p_null_text = > '- Select Rating-', p_item_id = > ' the ROWNUM # f01_ #', p_item_label = > ' label for ROWNUM f01_ # #', p_show_extra = > 'NO') 'Rating' of the sqa_customer_questions by id order
  
  Query runs as you like, but I don't know how to accept the values of the rows. I would like to insert the values of the selection list and their respective ID for all the entries in another table. I'm not able to find out how I could read data from these APEX_ITEMs and reach my goal.
  
  Any help is appreciated.
  
  Kind regards
  Jean-Pierre

  Nope,

  Can you put the app on apex.oracle.com

  In any case if you have a report like this

  SELECT id,
                  something
  FROM table
  

  You can do it for the

   SELECT id||APEX_ITEM.HIDDEN(2,id) id,
                  something
  FROM table
  

  And then reference it as APEX_APPLICATION. G_F02 (the first parameter provided to apex_item determine the number) in your process.

  See you soon

  Your VI is way too complicated. If you get a 2D array and you want just the second column, you should only use the Array Index to take off from the second column. That's all.

• Export data from the table

  Hello. Is it possible to export data from a table in Oracle using SQL Loader? If Yes, can you tell a good examples?

  Hello

  Hello. Is it possible to export data from a table in Oracle using SQL Loader?

  No, with SQL * Loader, you can load data from external files into tables not export.

  coil c:\temp\empdata.txt
  sqlplus abc.sql (assumes that abc.sql runs select * from emp)
  spool off

  It cannot work like this, because the declaration of the COIL is not recognized outside the SQL * Plus the term.

  But, you can include the statement of the COIL in abc.sql like this:

  spool c:\temp\empdata.txt
  select * from emp;
  spool off
  

  Then, you just have to run the SQL script as follows:

  sqlplus  @abc.sql 
  

  However, I advise you to use Oracle SQL Developer, this is a free tool and with it you can export a Table in several types of format (html, xml, csv, xls,...).

  Please find attached a link to this tool:

  Hope this helps.

• Reading data from a text (JS CS3) file tabs-delimited

  Hi - I'm working on a script to read data from a text file and use in a dialog box. But I hit a wall.

  I used a script from a previous post that defines a variable text document when the user script he chooses from a drop-down list.

  var myDialog = app.dialogs.add({name:"Map",canCancel:true});)
  {with (MyDialog)}

  {with (dialogColumns.Add ())}
  {with (borderPanels.Add ())}
  staticTexts.add ({staticLabel: "choose the location :"});})
  {with (dialogColumns.Add ())}
  
  var file = File("~/Desktop/myPlacesfile.txt");

  leader. Open ("r");
  var str = file.read ();
  leader. Close();
  var myPlaceList = str.split (/ [\r\n] + /);
  var myPlaceMenu = dropdowns.add ({stringList:myPlaceList, selectedIndex:0});})
  }
  }}}
  Ditto var = myDialog.show ();
  if(myResult == true) {}
  If (myPlaceMenu.selectedIndex == 0) {}
  myPlace var = ' - undefined ";
  } else {}
  myPlace var = myPlaceList [myPlaceMenu.selectedIndex];
  Alert (myPlace);
  }

  myDialog.destroy ();
  }

  That's what I do now:

  The text file is in this format:

  Value1 value2 [TAB]

  Value1 value2 [TAB]

  Value1 value2 [TAB]

  I need to have the drop down dialog box show only the value 1, and after that the user selects, the script returns only the value 2. (The alert is just there to test - I'm doing something else with the variable).

  Is there a way to view the first part of a tab-delimited line in the menu drop down and return the second half as a variable?

  Any help would be greatly appreciated.

  Thank you

  One of the possibilities is that it. Create a table to the left of the values of the tab of the dialog box. Then create an object that you use it as a table of correspondence. Roughly as follows:

  same thing as what you have

  leader. Open ("r");
  var str = file.read ();
  leader. Close();
  var array = str.split (/ [\r\n] + /);

  'pairs' are the table of correspondence

  pair of var = {};

  as before, 'myPlaceList' will be used for the menu drop-down
  var myPlaceList = [];

  var v;
  for (var i = 0; i)< array.length;="">
  {
  v = table [i] .split ('\t');
  pairs [v [0]] = v [1];
  myPlaceList.push (v [0]);
  }

  Add the drop-down list as before:

  var myPlaceMenu = dropdowns.add ({stringList:myPlaceList, selectedIndex:0});})

  the table of 'pairs' correspondence is used as follows: pairs ['value1'] returns 'value2 '.

  so in your script that would be:

  myPlace var pairs = [myPlaceList [myPlaceMenu.selectedIndex]];
