• How to create the column of the table for long-form Master detail relationship

  Apex 4.1

  Oracle 11g

  I created a form master detail and see the main table hotel_list and table hotel_mapping as detailed below.

  Hotel_list

  ID HOTEL_NAME

  1 Holiday Inn

  Hotel Hilton 2

  Hotel_mapping

  ID HOTEL_NAME MAPPING_NAME

  1 Inn Holiday Inn Select hotel

  2 holiday hotel Holiday Inn Select

  3 hotel Holiday Inn Holiday Inn Hotel

  4 Hilton Hotel Hilton Hotel chain

  Hotel Hilton 5 HiltonHotel

  Table Hotel_name Hotel_list is a linked table Hotel_mapping

  When I add a line to the Hotel_mapping table for the selected row in the hotel_list table, mapping_name of column is null, therefore impossible to create the relationship between the main table and the secondary table.

  I would like to know, how to create the relationship?

  Thank you very much

  Best regards

  Yong Huang,

  simple step see creating a form detailed master with APEX - Assistant Master retail

  and check how to maintain the relationship between two tables,

  simple return the packaged application «Sample of Masters details»

  and try to understand this concept...

  In your example, use Hotel_list.ID as a foreign key in the table Hotel_mapping

  and maintain the relationship with the column ID...

  and choose the display type of the column Hotel_list.ID in table Hotel_mapping as List(Query Based LOV) select.

  otherwise the best way is to create sample on oracle.apex.com

• Impossible to extract the data of an additional column in the table advance

  Hello

  We have an obligation to add an extra column to the table of advanced search. In addition, we need sort the table using this additional column.

  Now, we have achieved the following:

  1. the required VO was already extended previously and the additional column (LAST_UPDATE_DATE) is already present in the definition of the EO. So, we just added the tag for LAST_UPDATE_DATE in YOUR XML in the form:

  < ViewAttribute

  Name = "LAST_UPDATE_DATE".

  IsPersistent = "false".

  Type = "Oracle.jbo.domain.date"

  ColumnType = "DATE".

  AliasName = 'LAST_UPDATE_DATE. '

  Expression = "LAST_UPDATE_DATE."

  SQLType = 'DATE' >

  < / ViewAttribute >

  2 added a new MessageStyledText column, and updated the following property:

  Prompt = LastUpdateDate. Discover the Instance = TaskPerzSumVO. Display attribute = LAST_UPDATE_DATE. Sort Allowed = true

  The field is now visible in table advance and whenever we seek, attaches the value as ' 1901-01-01'. While I checked manually in the respective table, we have the appropriate data. But in the front end we do not get the data in our additional column of table in advance. In addition, if we try to sort the table by clicking the column LAST_UPDATE_DATE, we get the NPE error. Spec of NullPointerException is as follows:

  # # 0 in detail

  1. java.lang.NullPointerException

  at sun.misc.FloatingDecimal.readJavaFormatString(FloatingDecimal.java:989)

  Kindly help us to obtain the appropriate data in the additional column. Thank you!

  Kind regards

  Zahid

  Hi Zahid,

  This is the error:

  29000: unexpected exception caught: oracle.jbo.NoObjException, msg = Houston-25003: TaskEO.LAST_UPDATE_DATE object of type entity activity not found

  Tag entity by its use should have only name of EO and not the name of the attribute.

  Use instead under the tag:

  EntityUsage = "TaskEO".

  Also, I mentioned that rather tags manually, add it please try Wizard VO to add this attribute in EO attributes available list.

  UPDATE tablesubtype
     SET SUBTYPES  = TRIM (SUBTYPES);
  

  RTRIM do it alone will not be enough coz it takes away only right spaces and NOT left those.
  I guess in your case do a PLATE will be more advantageous to be safe and avoid left spaces in the future.

  For the intermediate spaces... try this.

  UPDATE tablesubtype
     SET SUBTYPES  = REGEXP_REPLACE (SUBTYPES, ' ', '');
  

  Hope this helps,

  It is a dynamic array, where a new line can be inserted using a button. Is that the dynamic nature of the question? ID hate to cancel all the flow dynamics and programming just to add a column, and then reapply them all.
  
  Thank you!

  Hello

  You do not add the columns in the object > palette (screenshot 2) of the Table. I suspect that the problem is that it is not enough on the page (in the content area) to add the column. In the screenshot 1, if you look at the width of the column highlighted from the space to the right of the table, you will see that a column can be added due to restrictions of space.

  Reduce the width of the column highlighted (temporarily), and then add a column. Once added, you can resize the columns to match the width of the page.

  Hope that helps,

• display / hide column of the table running

  Are there known issues with display / hide a column of the table at run time?

  I have a table that contains a column with a check box and another with a radio button.  If the user is allowed to select more than one row in the table (as indicated by a form variable), then I want to hide the column of radio and checkbox column.  If not, I want to show / hide the contrary.

  I show / hide the column header too.  When I preview the form, however, the data in the table appears "scoot" left and placed in the column that is hidden, so to speak.

  Here is a view of the design of the table:

  

  And a view of the execution of the table.  You can see the radio is hidden, but the "account number" column wants to crush in the (hidden) radio column,

  

  Here is the script, I'm very confident in this small snippet of code because the lines of account were filling wonderfully until I added the column of radio buttons and the script to show/hide.

  Put the account data in the table

  function

  setAccountData (objAccountRow, objAccountItem) //Pass in the line and data to complete line

  {

  stuff the line

  objAccountRow.accountNumber.rawValue

  = objAccountItem.accountNumber;

  objAccountRow.accountName.rawValue

  = objAccountItem.accountName;

  objAccountRow.accountBalance.rawValue

  = objAccountItem.accountBalance;

  display the check box or radio button, depending on the number of accounts they are allowed to select (as specified by the form variable)

  var searchNumAccounts = objFragment.resolveNode("searchNumAccounts").value; Variable //Form

      if (searchNumAccounts==1)

  { //show the column of radio buttons and hide the checkbox column }

  hideObject (objResultsSubform.accounts.HeaderRow.txtSelect);   <-it's exaggerated here, to hide the table for each row header column,...

  hideObject (objAccountRow.accountSelected);

  showObject (objResultsSubform.accounts.HeaderRow.txtRadioSelect);

  showObject (objAccountRow.radioSubform.radioGroup.selected);

  }

  on the other

  { //show the checkbox column and hide the column of radio }

  hideObject (objResultsSubform.accounts.HeaderRow.txtRadioSelect);

  hideObject (objAccountRow.radioSubform.radioGroup.selected);

  showObject (objResultsSubform.accounts.HeaderRow.txtSelect);

  showObject (objAccountRow.accountSelected);

  }

  }

  OK I got it. The table object implements a container to contain the fields. You hid the ok fields, but you then never reset the row in the table to have only two columns. I copied the parameter of the XML source so that I would have the exact width and then deleted the one I wanted to hide. Now everything works fine.

  See the example updated the.

• CSS: Pointing out the columns of the Table

  I want to use the border-bottom property to create underscore for the columns of the table. The complexity is when I try to create colspanned 'parent' or 'Super-colonnes' i.e. of the column heads that span 2 or more child/sub-headings heads. I need the underscore to stop a few pixels short of the next column, so that the user can see what child columns are included in the parent. When I tried to add white borders to the left and to the right, that he worked too good, in that not only it has created the space downstairs, he also created the space at the top (or bottom one above). Essentially the vertical borders to sit on top of the horizontal. Anyone can make sense what I said right? Any ideas how to get what I want (elegantly)?
  
  Thank you.

  Well, it was pretty easy. I just added the border-collapse attrib and set 'split' and now (white) borders left and right do not cut into the bottom border of the cell above.

  Hello

  I do not see, you use a Table of the ADF, but I see that you use Apache Trinidad. JSTL is executed analysis of time then that JSF is to render time, that's why it does not work what you see. Trinidad is a part of tr:switcher, and you can try this. Note that it doesn't ' r allow to change components by rank.

• How to remove columns from the table on the master 1-0?

  I have an array of 96 columns with strings. I also have the array of int 96-elemets (mask) with 1 and 0.

  What I want to do is to is to remove (or hide - but I read that it is not possible) all the columns with index corresponding to 0 in the mask table.

  example:

  columns in the table

  1 2 3 4 5

  mask

  0 1 0 0 1

  I want to remove the columns 1, 3 and 4 and leave only 2 and 5 in my table.

  How can I do?

  If I create loop for with i as the index of the column, when I do DeleteTableColumns() columns number decreases, and I get an error of range out of

  Or do I have an option to hide the unnecessary columns (not set their width to 1, it's very ugly-looking)?

  Please help me (())

  Hello rovnyart!

  1. removal of columns in the table:

  I suspect that the reason why you get the out-of-range error is due to fact that in your loop, you delete the columns in the table, you'll eventually end up by referring to a column that no longer exists, because the other columns before it have been deleted. While you remove each column of your table in the loop for example, the column index number will move, because you deleted the other columns in front of her.

  To resolve this, even if you delete a column in your loop, make sure that you take also into account that the index of the column is moved because of the removed columns.

  2 hide columns in table:

  You can use the ATTR_COLUMN_VISIBLE attribute to hide columns in the table:

  3 alternatives:

  Note that another alternative would also use a tree instead, control as the tree control also supports the hidable columns:

• How to select lines if a column has the same first and last characters?

  Hello

  I have a scenario that one of the columns in the table of the student is having names student, (Ex) John, Mary, Donald, Ana, Maria. In this case how can we write a query to retrieve lines for the values if the first and the last character of the student of identical names? Production is expected to be Donald, Ana.

  Frank answers the question in the subject of your post, but looking at your examples, I think you wanted

  WHERE lower (SUBSTR (student_name, 1, 1)) - 1 character

  low = (SUBSTR (student_name,-1)) - last character
