  Variable bind bind values of the object, not the object names. You cannot use bind variable as column name. Change:

  v_query := 'SELECT SUM (:p), week_num FROM week_tab GROUP BY week_num ORDER BY week_num'; 
  

  TO

  v_query := 'SELECT SUM (' || p_colName || '), week_num FROM week_tab GROUP BY week_num ORDER BY week_num'; 
  

  and

  OPEN p_refcursor FOR v_query
  USING p_colName;

• Using the name of dynamic column in datagrid selectedItems

  Hello

  I have a datagrid that is loaded with 2 columns. AllowMultiSelect is enabled.

  Based on the values selected at runtime, I get the correspondent selected the name of the column and its values and displays it on the screen of the HTML.

  GRP is datagrid

  dgrcl is a data grid column

  selflds is a table that has values 0,1,2,3

  selflds [0] = name, selflds [1] = age

  for (var l:int = 0; < grp.columnCount; l ++)

  {

  dgrcl = grp.columns [l];

  selflds [l] = dgrcl.dataField;

  }

  srhVals will have a single value selected in one point any

  get the corresponding name of the selected column and its value

  var srhVals:String;

  srhVals = String(grp.selectedItem[selflds[1]]);

  I'm trying to make the selection above instead in .selectedItems something like below. By doing that, I'll get all selected items, but not a single. If I try under syntax, I get error. Anyone have any ideas on how to make.

  srhVals = String(grp.selectedItems.selflds[1]);

  Hello

  I got my mistake, there should be no point after selectedItems operator;

  I found a solution - it goes like this:

  for (var g:int = 0; g<>

  {

  srhVals = srhVals + String(grp.selectedItems[g][selflds[1]]);

  }

  If the whole scenario is like this:

  DataGrid:

  Name age

  a               20

  b               30

  c               40

  d               50

  I select b, d in the user interface. At runtime, I get the selecteditem as 'Name' column name programmatically, loops through the selecteditems and store the value in srhVals b, d.

  b, d will finally be shown in the user interface.

  Hi Forum members,

  I am looking for a query display the name of the tag as the column name and the value in the tag as a row of data.

  I have to print the values within the tag to a file by choosing the value of the flags. the sequence of the tags will vary each time, as the tag name will change dynamically.

  So here is the example of input data and the expected output. The string in the text column must be separated as the column names and values.

• Question PLSQL with variable compound column names

  Hello gentlemen,
  

  
  

  I'm new to PLSQL and I would like to display some values of columns, which are listed in the defined variable in dbms.output. I created under code, which I think it could work, but I guess that it is far from correct.

  
  

  DECLARE
v_TEMP_QUERY VARCHAR2 (1000 BYTE);
v_TEMP_VALUE VARCHAR2 (1000 BYTE) := 'FILTER_01, FILTER_02';

BEGIN  
FOR v_TEMP_LOOP IN
(v_TEMP_QUERY := 'SELECT DISTINCT ' || v_TEMP_VALUE || ' FROM CW_PAGE_COMPONENT_TEMPL WHERE COMPONENT_TEMPL_ID = 10000034642';
EXECUTE IMMEDIATE v_TEMP_QUERY; )
LOOP
DBMS_OUTPUT.PUT_LINE (v_TEMP_LOOP.v_TEMP_VALUE);
END LOOP;
END;

  
  

  Thanks in advance for your help and advice on this issue and sincerely,

  Sebastian

  OK, first of all, you're confused concepts here.

  cursor loop FOR waiting for a slider must be provided, and yet you offer an assignment statement and a command immediately execute for it.  Syntax is not valid.

  Secondly, you force the way of the use of dynamic SQL, which is generally bad practice.  This use of the SQL is rarely necessary, because it often indicates that functional requirements, database design, or design/code enforcement has not examined properly... the first question is "why don't you know the names of the columns to select.  With dynamic columns in your query, you need some kind of dynamic code to manage the results of the query, you will not be able to reference the columns directly by name.

  Thirdly, the DBMS_OUTPUT package doesn't make "blank".  This may sound pedantic, but it's a common mistake that people make.  There is no fill data dbms_output buffer.  It relies on call code/interface to read the contents of the output buffer and display it in fact (for example, in SQL * more you use SQL * Plus the command "set serveroutput we ' to achieve)

  In general, in a well designed where application you know your columns you would only make...

  Start
  I'm in (select distinct filter_01, filter_02 from vw_page_component_templ where component_templ_id = 10000034642)
  loop
  dbms_output.put_line (i.filter_01 | ',' | i.filter_o2);
  end loop;
  end;

  If the columns are dynamic, then you have three options:

  (1) create a ref and pass cursor who back, extracting the content for example

  sys_refcursor getRc function returns (in numbers, in colnames templ_id varchar2) is
  RC sys_refcursor;
  Start
  Open rc for ' select distinct ' | colnames |' from vw_page_component_templ where component_teml_id =: 1' using templ_id;
  return rc;
  end;

  In SQL * more:

  var r refcursor; -It creates a variable in SQL * Plus ref cursor type
  Start
  : r: = getRc (10000034642, ' filter_01, filter_02');
  end;
  /
  print r;      -It's SQL * command to retrieve the cursor open and display the results

  (2) create an object and collection of the right structure to receive the results and use execute immediate to select IN this structure.

  (I will not show in this way, because it is absolute rubbish, and if you know the columns that you want to create the object and the collection, then you should not use dynamic SQL in the first place)

  (3) use the DBMS_SQL package to run the query and retrieve the data from the column in position rather than example:

  create or replace procedure run_query (p_sql IN VARCHAR2) is
  v_v_val varchar2 (4000);
  number of v_n_val;
  date of v_d_val;
  number of v_ret;
  c number;
  number d;
  whole col_cnt;
  Boolean f;

  
  rec_tab dbms_sql.desc_tab;
  number of col_num;
  v_rowcount number: = 0;
  Start
  -create a slider
  c: = dbms_sql.open_cursor;
  -analyze the SQL statement in the cursor
  DBMS_SQL. Parse (c, p_sql, dbms_sql.native);
  -run the cursor
  d: = dbms_sql.execute (c);
  --
  -Describe the columns that are returned by the SQL statement
  DBMS_SQL. DESCRIBE_COLUMNS (c, col_cnt, rec_tab);
  --
  -Local variables Bind to return to the different columns according to their types
   
  dbms_output.put_line (' number of columns in the query: ' | col_cnt);
  1.col_cnt j
  loop
  case rec_tab (j) .col_type
  When 1 then dbms_sql.define_column (c, j, v_v_val, 2000); -Varchar2
  When 2 then dbms_sql.define_column (c, j, v_n_val);      -Number
  12. When can dbms_sql.define_column (c, j, v_d_val);     -Date
  on the other
  DBMS_SQL.define_column (c, j, v_v_val, 2000);  -Any other type of return as varchar2
  end case;
  end loop;
  --
  -Display columns are returned...
  dbms_output.put_line ('- Columns-');
  1.col_cnt j
  loop
  dbms_output.put_line (rec_tab (j) .col_name |') -' || case rec_tab (j) .col_type when 1 then 'VARCHAR2 '.
  When 2 then 'NUMBER '.
  When 12 can "DATE".
  "Otherwise, 'Other' end);
  end loop;
  dbms_output.put_line('---');
  --
  -This part generates the DATA
  loop
  -Retrieves a row of data using the cursor
  v_ret: = dbms_sql.fetch_rows (c);
  -Output when no more line
  When the output v_ret = 0;
  v_rowcount: = v_rowcount + 1;
  dbms_output.put_line (' line: ' | v_rowcount);
  dbms_output.put_line('---');
  -Extract the value of each column of the row
  1.col_cnt j
  loop
  -Fetch each column to the correct data type according to the description of the column
  case rec_tab (j) .col_type
  When 1 then dbms_sql.column_value (c, j, v_v_val);
  dbms_output.put_line (rec_tab (j) .col_name |': ' | v_v_val);
  When 2 then dbms_sql.column_value (c, j, v_n_val);
  dbms_output.put_line (rec_tab (j) .col_name |': ' | v_n_val);
  12. When can dbms_sql.column_value (c, j, v_d_val);
  dbms_output.put_line (rec_tab (j) .col_name |': ' | to_char (v_d_val,' DD/MM/YYYY HH24:MI:SS'));))

  As you can see with this method, you can extract the column details, including the name and data etc. types and then extract each line and extract the data from the column position.

  Of course, this is quite complex, so it would be a last resort.

• OBIEE dynamic column headings based repository Variables

  Hello

  How can we provide variable name of the repository (from RPD) as column headings in reports (presentation Services).

  Can you please suggest me how to do it?

  Thanks in advance...

  RAM

  Hello

  You can use the following link.

  Oracle Business Intelligence 11g: OBIEE 11 g dynamic column headings

  I used the variable presentation here, you can substitute the variable repository. The difference is that you don't need to create variable presentation, instead you use repository variable there.

  If you are not clear with this, pleas come back. I'll write a new message on your problem.

• Extraction of values based on column names

  Hello

  I have three tables. Table A table contains a column with all column_names in the table b. table B is to have an emp_id and other fields that are stored as values in the column of the TABLE.  I need to get the emp_id and value from the column of table B based on data of Table A. and store it in another table.

  Example:

  Table has -col1

  Emp_name

  Emp_sal

  Emp_dept

  Table B

  Emp_id Emp_name Emp_sal Emp_dept

  1001 ABC 1000 sales

  1002 XYZ 2000 SVC

  TABLE C

  Emp_id Emp_details value

  1001 Emp_name ABC

  1001 Emp_sal 1000

  1001 Emp_dept sales

  1002 Emp_name XYZ

  1002 Emp_sal 2000

  1002 Emp_dept SVC

  Using the list of TABLE A, I have to select each Id and corresponding to the value of TABLE B and even insert in TABLE C. I know that we can use a loop for, but I have trouble choosing the name of column based on the value of the slider. Can anyone help?

  
  

  Hello

  Looks like you want to do 2 things rather difficult:

  (1) unpivot data from several columns in the column 1 value

  (2) get the column names for the another table unpivot operator

  Let's start with how you could do just part 1, unpivoting data:

  INSERT INTO table_c (emp_id, emp_details, value)

  WITH all_varchar2 AS

  (

  SELECT emp_id

  emp_name

  TO_CHAR (emp_sal) AS emp_sal

  emp_dept

  --Include all columns, you might need

  OF table_b

  )

  SELECT emp_id, emp_details, value

  Of all_varchar2

  UNPIVOT (value

  FOR emp_details IN

  (emp_name - dynamic

  emp_sal - dynamic

  emp_dept - dynamic

  )

  )

  ;

  Value is a column, everything happens in this column must have the same (or a very similar) data type.  The subquery all_varchar2 converts all columns that you can rotate in VARCHAR2s (if they are not already VARCHAR2s) so that they are ready to rotate.  You might consider doing a permanent display for this.

  Now, instead of hard-Ghoshal the 3 line marked "Dynamics", you seek to table_a.  You will know beforehand what are these columns, and you won't even know there will be the number of columns. You need instructions SQL dynamic to write this part of the INSERT statement for you at run time.

  Here's a way to do it in SQL * more and SQL:

  -The preliminary motion

  COLUMN col_list_col by col_list new_value

  SELECT LISTAGG (col1, ',') within THE GROUP (ORDER BY col1)

  AS col_list_col
  FROM table_a;

  -Main return (dynamic):

  INSERT INTO table_c (emp_id, emp_details, value)
  WITH all_varchar2 AS
  (
  SELECT emp_id
  emp_name
  TO_CHAR (emp_sal) AS emp_sal
  emp_dept
  --Include all columns, you might need
  OF table_b
  )
  SELECT emp_id, emp_details, value
  Of all_varchar2
  UNPIVOT (value
  FOR emp_details IN
  (& col_list
  )
  )
  ;

  Dynamic SQL often works like this.  First, you make a preliminary motion to write the part that is not know before execution.  Then, you run the main statement, which has the integrated preliminary query results.

  If you do this in PL/SQL, you use a string variable ordinary for col_list, instead of a substitution variable.

• Creating a dynamic column editable

  I tried to make my dynamic columns as editable. The problem is that my dynamic columns are nested.
  
  Now editable column works fine when I have diff columns with a different name. For example, col1, col2, col3 (not nested)
  
  Or I nested columns like "pass"(parent) given two columns col1 and col2. ".
  
  But, when I use them in a dynamic of columns in which all of them have the same name, in the example below, each with the same name 'col', I can change all of them, but the textfield never faded away, when I click on ENTER.
  
  
  Suppose I have an editable column with col name:
  

  for (final CategoryTypeVO type : typeList)
                  {
                         TableColumn<ItemVO, Integer> col = new TableColumn<ItemVO, Integer>(type.getTypeName());
                        col.setMinWidth(100);
                        col.setEditable(true);
                        col.setCellFactory(cellFactory);
                       
                       
                        col.setOnEditCommit(
                                 new EventHandler<TableColumn.CellEditEvent<ItemVO, Integer>>() {
                                 public void handle(TableColumn.CellEditEvent<ItemVO, Integer> t) {
                                 ((ItemVO)t.getTableView().getItems().get(
                                 t.getTablePosition().getRow())).getListType().get(type.getTypeId()).setQuantity(t.getNewValue());
                                 }
                                 });
                         quantity.getColumns().add(col);
                       }

  and cellfactory as:
  

  final Callback<TableColumn<ItemVO, Integer>, TableCell<ItemVO, Integer>> cellFactory = new Callback<TableColumn<ItemVO, Integer>, TableCell<ItemVO, Integer>>() {
                      public TableCell call(TableColumn p) {
                           return new EditingCell();
                      }
                 };

  and Editing class as
  

  class EditingCell extends TableCell<ItemVO, Integer> {
             
             private TextField textField;
            
             public EditingCell() {}
            
             @Override
             public void startEdit() {
                 super.startEdit();
                
                 if (textField == null) {
                     createTextField();
                 }
                
                 
                 setGraphic(textField);
                 setContentDisplay(ContentDisplay.GRAPHIC_ONLY);
                 textField.selectAll();
                 Platform.runLater(new Runnable() {
                     @Override
                     public void run() {
                         textField.requestFocus();
                     }
                });
             }
            
             @Override
             public void cancelEdit() {
                 super.cancelEdit();
                
                 setText(String.valueOf(getItem()));
                 setContentDisplay(ContentDisplay.TEXT_ONLY);
             }
        
             @Override
             public void updateItem(Integer item, boolean empty) {
                 super.updateItem(item, empty);
                
                 if (empty) {
                     setText(null);
                     setGraphic(null);
                 } else {
                     if (isEditing()) {
                         if (textField != null) {
                             textField.setText(getString());
                         }
                         setGraphic(textField);
                         setContentDisplay(ContentDisplay.GRAPHIC_ONLY);
                     } else {
                         setText(getString());
                         setContentDisplay(ContentDisplay.TEXT_ONLY);
                     }
                 }
             }
             
            
             
        
             private void createTextField() {
                 textField = new TextField();
                 //textField.setText(getString());
                 textField.setText("0");
                 textField.setMinWidth(this.getWidth() - this.getGraphicTextGap()*2);
                 
                 textField.focusedProperty().addListener(new ChangeListener<Boolean>() {
  
                        @Override
                        public void changed(ObservableValue<? extends Boolean> arg0, Boolean arg1, Boolean arg2) {
                            if (!arg2) {
                                commitEdit(Integer.parseInt(textField.getText()));
                            }
                        }
                    });
                 
                 textField.setOnKeyReleased(new EventHandler<KeyEvent>() {
                     @Override public void handle(KeyEvent t) {
                         if (t.getCode() == KeyCode.ENTER) {
                             commitEdit(Integer.parseInt(textField.getText()));
                         } else if (t.getCode() == KeyCode.ESCAPE) {
                             cancelEdit();
                         }
                     }
                 });
             }
  
            
             private String getString() {
                 return getItem() == null ? "" : getItem().toString();
             }

  Now what happens is this thing works fine if I separate columns with distinct names. But when it comes to dynamic columns, it fails, once I have edit a cell, the text field never leaves his place. It gets stuck in the cell. Any help!

  Do not know what is the problem in your code, but it is easier to use TextFieldTableCell than building your own TableCell from scratch.

  This change to the example I posted in How to create a tableview for this? works for me:

      // Make table editable:
      table.setEditable(true);
  
      final TableColumn nameCol = new TableColumn("Name");
      nameCol.setCellValueFactory(new PropertyValueFactory("name"));
      nameCol.setCellFactory(TextFieldTableCell.forTableColumn());
      final TableColumn priceCol = new TableColumn("Price");
      table.getColumns().addAll(nameCol, priceCol);
  
      choiceBox.getSelectionModel().selectedItemProperty()
          .addListener(new ChangeListener() {
            @Override
            public void changed(ObservableValue observable, Category oldValue, Category newValue) {
              table.getItems().clear();
              priceCol.getColumns().clear();
              for (final Type type : newValue.getTypes()) {
                final TableColumn col = new TableColumn(type.getName());
                col.setCellValueFactory(new Callback, ObservableValue>() {
                  @Override
                  public ObservableValue call(CellDataFeatures cellData) {

                    }
                  }
                });
  
                // Make column editable:
                col.setEditable(true);
                col.setCellFactory(TextFieldTableCell.forTableColumn(new NumberStringConverter()));
  
                priceCol.getColumns().add(col);
              }
              table.getItems().setAll(dao.getItemsByCategory(newValue));
            }

• IN parameter is the string of column names I want to SELECT delimited

  Hi guys,.
  
  Please bare with me. Not a pro at writing stored procedures.
  
  What I try to do is to pass a parameter of 'IN' to the proc. The setting is a varchar2 which is a comma-delimited string.
  I want to put this string in the SELECT statement.
  
  This setting is called "P_SelectFields".
  
  The value in the passage in the proc is like:
  P_SelectFields = ' CUSTOMERS SUM (CLI_SERVED) AS SUM (EI_INTC) + SUM (NEI_INTC) AS INTERVENTIONS,
  SUM (TOT_EMPRTN) AS EMP_RETURN, SUM (TOTAL_RTS) AS SCHOOL_RETURN
  "
  
  
  That's what I've got and I know that it works, if I put the string instead of the parameter it works. !
  
  PROCEDURE GET_NATIONAL_TOTAL_RESULTS (P_SelectFields IN varchar2, P_AGREEMENT_TYPE_IND AGREEMENT_TYPE.agreement_type_ind%TYPE, io_cursor in SYS_REFCURSOR)
  IS
  BEGIN
  OPEN FOR Io_cursor
  
  SELECT year_desc,
  P_SelectFields - that's where I want my partameter go.
  
  OF SPF_RESULT_VW
  WHERE r_num = 1 - FILTER for the LAST PERIOD for EACH YEAR
  and agreement_type_ind = P_AGREEMENT_TYPE_IND - desired FILTER FOR Agreement_type_ind
  GROUP BY year_desc
  ORDER BY year_desc
  ;
  
  END GET_NATIONAL_TOTAL_RESULTS;
  
  
  That's what I'm after you run the proc.
  
  YEAR_DESC = 2011-2012
  : B2 = SUM (CLI_SERVED) ACE, SUM (EI_INTC) CUSTOMERS + EMP_RETURN SUM (NEI_INTC) AS OF THE INTERVENTIONS, SUCH AS SUM (TOT_EMPRTN), SUM (TOTAL_RTS) SCHOOL_RETURN
  
  Where is ': B2 = "come from?".
  
  What can I do to make my parameter is "picked up" by the proc?
  
  Thank you

  Firstly: in relational databases, there is no distinction between 'fields '. Tables is not 'fields', they have columns.
  It is my experience that that call columns 'fields' basically treats the database as a flat file system. It's a very bad idea!

  If you want to pass as a parameter column names, you need dynamic SQL.
  However, PL/SQL was invented to reduce the analysis and using of the dynamic SQL, you'll at least soft-parse each statement.

  Dynamic SQL is obviously in the documentation, but most people here think that they don't need to read the documentation.

  So, for once
  glance

  OPEN io_cursor FOR
  'SELECT year_desc,'||
  P_SelectColumns||
  ' FROM SPF_RESULT_VW '||
  'WHERE r_num = 1 '|| --FILTER FOR LATEST PERIOD FOR EACH YEAR
  'and agreement_type_ind = P_AGREEMENT_TYPE_IND '||-- FILTER FOR desired Agreement_type_ind
  'GROUP BY year_desc '||
  'ORDER BY year_desc'
  ;
  

  Please note that I have renamed the parameter.

• Dynamic column headings

  You will need to run a report on the budget for the past 3 calendar years. I can produce the report but has difficulty to print the column position properly review this report need to run each year. Is it possible to appoint the year on appropriate using bi publisher and APEX V4 column header?
  
  Oracle: 10G
  
  ex:
  If the report runs this year: column must be 2010,2009,2008.
  If the report is run next year: column name must be 2011,2010,2009
  .....
  
  Thank you.

  Oops, Yes, the password has expired. I have reset. Try again... same settings.

  I was not aware of the position PL/SQL column type. You can specify in the 'Report of the attributes' tab in your area. At the top of this page, there is a section of Type "headings". If you click on the option button "PL/SQL", it displays a text box field to specify PL/SQL code to determine the column headers. This is what is used in my sample application. It calls the function 'GET_QUERY_COLS', you can find the SQL Workshop of my sample workspace area.

  A brief description of what is happening in my example...

  In my area "Dynamic motion", I run a dynamic SQL query because the values of the year for the columns are unknown. It runs the report of dynamic query and stores the dynamic query to the P1_REPORT_QUERY point. Then, this value of the element is passed in the function GET_QUERY_COLS that returns the name of the column, that I need. Of course, I have the user selects a range which essentially defines the columns, I need.

  Thank you

• Generate CSV with pl.sql column names

  Hi guys,.
  
  Well, I am back after a long hiatus in this form, was occupied by SAP BI project.
  
  Now do some oralce - sap project, well here, I needed to generate a CSV of many many queries,
  
  I can do via sql, but I tot it would be better to write a package or a common procedure to generate csv files
  
  ex, if I pass the query to the proceudre it should generate csv on the server directory file, later I send these file to the users concerned.
  
  The e-mail part is later, but first of all is to have a package of generic to launch and run the query n generate the csv file.
  
  I guess this should be possible using native dynamic sql and utl_ package, but I don't know how to get the columns name,
  
  If one has implemented this please explain me the way,.
  
  ex:
  

  Select emp,mgr, empno from emp;
  
  emp mgr empno
   1    1    123
    2   1    234
  
  something like that
  hope my question is clear 

  Maybe try this

• use a (selection list) element as the column name in the select?

  I have a popup LOV key based on a select (dynamic list of values)
  I want to display and return - select columns in the select statement to be determined by another list.
  
  I tried:
  
  Select distinct: P133_COLUMN d: P133_COLUMN r
  FROM MyTable
  
  but then I don't you the value of: P133_COLUMN... so if: P133_COLUMN is 'EMPNO' LOV popup displays the text "EMPNO" and referred the text 'EMPNO', not the empno column values...
  
  If I change
  
  Select distinct P133_COLUMN d & P133_COLUMN r

  Anyone?
  
  Also, I was wondering if it is possible to set the textfield object in the item popup LOV to accept the input text directly as well as the selected value, but the first part of the question is the important part.

  Hello
  
  I have a query that will return different columns according to the entry. I'm trying to get the dynamic name of cfgridcolumn. For example, in code below column name ABC has been hard-coded.
  
  < bindonload cfgrid = "yes" bind = "cfc:xyz.entityList ({cfgridpage}, {cfgridpagesize}, {cfgridsortcolumn}, {cfgridsortdire ction})" >
  < name cfgridcolumn = 'ABC' header = 'ABC' / >

  Is there a way were, we can cite the columnname as a variable? Something similor to:
  
  < bindonload cfgrid = "yes" bind = "cfc:xyz.entityList ({cfgridpage}, {cfgridpagesize}, {cfgridsortcolumn}, {cfgridsortdire ction})" >
  < cfloop list = "" #entityList.ColumnList # "index 'index' = >"

  Any help would be greatly appeciated.
  
  Thank you very much

  Convert a table like, your columnlist

  Then you can assign it to a gridcolumn as,
