  Hello

  What exactly do you do?

  If you want to display the tables containing these columns, you can query the view data dictionary USER_TAB_COLS (or ALL_TAB_COLS, or, if you have privileges, DBA_TAB_COLS).

  For example:

  SELECT table_name, column_name

  Of user_tab_cols

  WHERE nom_de_colonne IN ('DNAME', 'FNAME', 'FIRST_NAME', 'LAST_NAME', 'LNAME') - or else

  ORDER BY table_name, column_name

• How can I iterate over the columns of a REF CURSOR?

  I have the following situation:
  

  DECLARE
     text   VARCHAR2 (100) := '';
     
     TYPE gen_cursor is ref cursor;
     c_gen gen_cursor;
  
     CURSOR c_tmp
     IS
          SELECT   *
            FROM   CROSS_TBL
        ORDER BY   sn;
  BEGIN
     FOR tmp IN c_tmp
     LOOP
        text := 'select * from ' || tmp.table_name || ' where seqnum = ' || tmp.sn;
  
        OPEN c_gen FOR text;
  
        -- here I want to iterate over the columns of c_gen
        -- c_gen will have different number of columns every time,
        --        because we select from a different table
        -- I have more than 500 tables, so I cannot define strong REF CURSOR types!
  
        -- I need something like
        l := c_gen.columns.length;
        for c in c_gen.columns[1]..c_gen.columns[l]
        LOOP
            -- do something with the column value

  As you can see from the comments in the code, I couln would find examples on the internet with a REF CURSOR low and selecting from multiple tables.
  What I found was:

  CREATE PACKAGE admin_data AS
     TYPE gencurtyp IS REF CURSOR;
     PROCEDURE open_cv (generic_cv IN OUT gencurtyp, choice INT);
  END admin_data;
  /
  CREATE PACKAGE BODY admin_data AS
     PROCEDURE open_cv (generic_cv IN OUT gencurtyp, choice INT) IS
     BEGIN
        IF choice = 1 THEN
           OPEN generic_cv FOR SELECT * FROM employees;
        ELSIF choice = 2 THEN
           OPEN generic_cv FOR SELECT * FROM departments;
        ELSIF choice = 3 THEN
           OPEN generic_cv FOR SELECT * FROM jobs;
        END IF;
     END;
  END admin_data;
  /

  But they have only 3 tables here and I have like 500. What can I do here?

• Change data type for the column in a table - Oracle 8i

  Team,
  
  I need to change a VARCHAR2 column in number.
  
  ALTER table xyz change number abc;
  
  By giving the above statement, it says I need empty this column before you change.
  
  I can't change the data type before emptying this column.
  
  Please indicate any other solution. Give me some suggestions.
  
  Empty the column for me here BIG task.

  user11081688 wrote:

  Not according to the documentation:

  You can change the data type of any column or decrease the size of the entire column if all rows in the column contains NULL values.

  Please indicate any other solution. Give me some suggestions.

  You can add another column with the correct data type.

  ALTER TABLE xyz ADD COLUMN def NUMBER;
  UPDATE TABLE xyz SET def = TO_NUMBER(abc);
  ALTER TABLE xyz DROP COLUMN abc;
  ALTER TABLE xyz ADD COLUMN abc NUMBER;
  UPDATE TABLE xyz SET abc = def;
  ALTER TABEL xyz DROP COLUMN xyz;
  

  If I remember correctly, Oracle 8i does not support the change of name of column if this solution is a bit more complicated than 9i and above. Another option would be to create a new table with CREATE TABLE AS... SELECT, drop the old one and rename a new one to the old.

• collection of panels reorder and hide the columns of af: table

  Dear Experts,

  I use JDev 11.1.1.7.0.

  I would like to customize the model from the collection of a table so that I can set the Visible property of each column and displayIndex.

  How can I replace the model of collection related to the af data: table in order to browse the columns and set these properties?

  Best regards, Atanas.

  Hello

  On the bean of the jsf/jspx page of your table, where you set your table method, you must code as follows:

  public void setYourTable(RichTable t1) {
      this.YourTable = t1;
  
      List list = t1.getChildren();
          for (UIComponent component : list ){
              if (componente instanceof RichColumn){
  
          ((RichColumn)componente).setDisplayIndex(theOrderNumberYouWantoToSetToTheColumn);    //set a number order to the column of the table
          ((RichColumn)componente).setVisible(true/false);                    //true or false to show or not
  
          }
      }
  
  }
  

  For each column, you must set the number columns are ordered by, and whether they are visible or not.

  Kind regards

  Hello
  Could you help me to write the code. My column in a table are 13,14,15,16

  If I type in field 13 then 14 and 16th column should turn off and
  If I go should disable the value in field 14 and 13 and 15 column.

  How can I do this?

  Thank you & best regards
  CORINE

  I have not tested this code; but the following may be your approach:
  In the field 'Attributes of the element' of column 13, you can call a javascript function:

  onblur = "javascript:updateCols(this);"
  

  In your browser, right click on each of your columns (one at a time) and select "inspect element" to check the attributes of the HTML element. Assuming that column in the form of your table 13 is rendered in the HTML like f13, 14th column as f14, 15 columns as f15 and 16th as f16, write this JS function in the HTML page header:

  The JS function above is triggered when the user moves out of column 13. The function then checks the length of the value entered by the user in column 13. If the length is greater than 0, it disables the columns 14th and 15th. Otherwise, it allows them.

  The code above is for your first scenario:

  If I get home should disable the value in the field column 13 then 14 and 16

  You can do the same for the other scenario.

  Hope this is clear. Or otherwise, give me access to your workspace and I try the here above.

• Correspondence of the columns from one table to another

  I have a database column that contains the name of a person. I have another table that has a column that contains the names separated by a comma.

  I want to match records where all records of two columns have a corresponding name. I tried this:

  < cfquery name = "MyQuery" datasource = "myds" >

  SELECT *.

  OF TBL_A

  WHERE TBL_A.customername IN (#DifferentQuery.ListOfNames #)

  < / cfquery >

  Everything that I try results in only get a recording. Basically, I want to get all records from a table where one of its columns contains the name of a column in another table.

  It's a many-to-many relationship. That is to say an editorial can be linked to many ads, and vice versa.  He is best represented with three tables. Such as:

  Table: [Editorial] column: [EditorialID (PK), EditorialText,...]

  Table: Columns of the [advertiser]: [AdvertiserID (PK), AdvertiserName]

  Table:   [Editorial_Advertisers] columns: [EditorialID, AdvertiserID]

  The name of the advertiser throw himself into a column...

  my client can decide which ads get related to which editorials

  The third table stores the relationship between ads and editorials.  So instead of storing a list of advertisers, you need to insert record for each EditorialID + AdvertiserID combination. You can then use joins to retrieve all the advertisements for EditorialID 123.

  SELECT  a.AdvertiserName
  FROM     Editorial_Advertiser ea INNER JOIN Advertiser a ON ea.AdvertiserID = a.AdvertiserID
  WHERE   ea.EditorialID = 123
  

• How to hide the column in a table in the adf.

  I created the table of the ADF and surround it in the collection of panels, the data in the table from the bean to support variable. Depending on the State, there are a few columns that must hide with the user. I used visible = "false", where the false value will come from backing bean. However the user to the table always have the ability to display the column. Is there any one to hide the column with the user at all times. Fixing the code example:

  < af:column sortable = "false" headerText = "column1" id = "c13" visible = "false" >

  "" < af:outputText value = "{row.columns1} ' id ="ot13"/ >

  < / af:column >
