  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

• Problem in inserting records into a table (MS Access) where the name of the column against

  I have a table with the name of column say first #Name and when I insert a value in the table it gives an error and it does not let me insert some values which he... Is it possible to enter the value in this column by fleeing this hash. I have a constraint that I can not change the name of the column...

  If it was Oracle you would put quotes around the name of the column. Not sure if happens the same for MS Access, because I do not play with the toy databases.

  for example

  Insert into tablename ("First#Name") values ('Fred');
  

• How to find a table, using the name of the column in the database schema

  Dear all,
  
  Please help me on
  
  using the name of the column, how to find a table name in the database schema.
  
  Thanks in advance

  Hello

  You can query the data dictionary views all_tab_columns and user_tab_columns.
  For example, to find the tables in the scott schema have called deptno columns:

  SELECT  table_name
  FROM    all_tab_columns
  WHERE   owner           = 'SCOTT'
  AND     column_name     = 'DEPTNO';
  

  Remember that anything inside quotes is case-sensitive.

  The all_tab_columns view has one row for each column in each table (or view) that you have the privileges to use.
  The user_tab_columns view is a subset of all_tab_columns, containing only your own tables (and views).

• Display the column name of the column more recently updated

  I wonder if it is possible to display the name of the column in the column most recently updated in a table.

  Example:

  Emp table

  Name

  Height

  Weight

  Age

  Update_Date

  Update_Column

  Original record (03/20/14)

  Name size weight Age Update_date Update_Column

  John                                                 03/20/14          Name

  Then someone comes and update the height on 22/03/14:

  Name size weight Age Update_date Update_Column

  John 5'9 03/22/14 height

  And the Update_date and the Update_column would change again if someone came and put a value for the age. And so on.

  Is this possible?

  Also, if the above is possible, would it be possible to display the name of extreme right column if a user updated several columns at the same time?

  Example:

  User updates the sub-folder:

  Name size weight Age Update_date Update_Column

  John 5'9 03/22/14 height

  And adds weight and age at the same time on 24-03-14:

  Name size weight Age Update_date Update_Column

  John 5'9 150 31 03/24 / 14

  The Update_Column would display age because it is the furthest to the right. (Think by reading from left to right, the column that has been updated if the extreme right)

  So to sum things, I need to be able to display Updated_date (which will be the date of the day when the record is the last updated) and Updated_Col (which is the column name of the column was last updated, and if multiple columns are updated then display that value has been updated last in)

  I hope that the examples help to clarify things.

  Thank you

  Steven

  I think I found a solution.

  delimiter //
create table a (
  id int (10) unsigned auto_increment,
  a int(10),
  b int(10),
  update_date datetime NULL,
  update_column varchar(16) NULL,
  primary key (id)
)//

  create trigger bu_a before update on a for each row begin
  set NEW.update_date = NOW();
  set NEW.update_column = NULL;
  -- you need to start with the rightmost column if you want
  -- that matched with the highest priority
  if OLD.b != NEW.b then
   set NEW.update_column = "b";
  elseif OLD.a != NEW.a then
   set NEW.update_column = "a";
  end if;
end //

  TEST

  insert into a (id,a,b) values (1,1,1), (2,1,1), (3,1,1), (4,1,1)[
update a set b = 2 where id = 2;
update a set a = 2 where id = 3;
update a set a = 2 where id = 4;
update a set b = 2 where id = 4;
select * from a;

  DISPLAY

  ID  A   B   UPDATE_DATE                    UPDATE_COLUMN
1   1   1   (null)                          (null)
2   1   2   March, 24 2014 23:22:33+0000      b

• 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

• Get the name of the column in the Select row

  Hi guys,.
  
  I paint a picture in which there is commandlink in a line for each Column.When I click af:commadLink I want to get the name of the column on which commandLink is clicked.
  I tried to get currentRow Clicked from DCIteratorBinding but I want the column name or a column and index.
  
  Thank you

  Hello

  I added a tag of f: attribute for the command link, give it a name and provide the column name as value. In the ActionListener method, access you the link to actionEvent.getUIComponent (). Here call you getProperties or get attributes (one of the two exists) which returns a map. On the plan that you call get ("the f_attribute name") to get the column name

  In my Jdev 11.1.2 app I want to know the name of the attribute column that is modified. I am able to get the attribute name that currently use the getAttrbute() on the line (if you open the VO we see name |) Type of | Column, etc.). How can I get the name of the column?

• You can addItem() when you do not know the name of the column?

  I am trying to enter data into a DataGrid via XML. I do not know in advance what will be the names of the columns. I understand that it is supposed to function as:

  var sampleItem:Object = {ColName:10};

  dataGridMain.addItem (sampleItem);

  but it's no help if you don't know what will be the name of the column (column).

  Can I replace the value (10) with variables that match my xml values (output.row [0] .col [0]) and it works fine. But if I try to do the same for column name, it doesn't quite work. How can I use a dynamic of the names of columns in the dataGrid?

  gr8 to know that you have found the solution...

  Alternatively, you can make the dynamic columns same name as the name of the xml tag using dataprovider. Here's a simple example.
