• DELETE or empty field containing the BLOB in the roacle table

  Hi all.
  
  I have a table in the schema with a BLOB field. I store the photo of the employee in this area. Fields of this table are emp_name emp_id (number) (varchar2) and emp_photo (BLOB). I would like to ask if there is a way in pl / sql I could empty this field to null BLOB or reset this field so that the user can modify the saved photo graph and record another.
  
  I'm looking for is something like
  

        alter table employee set emp_photo = empty_blob() or alter table employee set emp_photo = null
  
    

  Thanks in advance.

  Looking in the documentation for Oracle? For example, in the EMPTY_BLOB, EMPTY_CLOB of the SQL language reference section?

  >
  Goal
  EMPTY_BLOB and EMPTY_CLOB return an empty LOB Locator that can be used to initialize an LOB variable or in an INSERT or UPDATE statement to initialize a LOB column or attribute EMPTY. EMPTY means that the LOB is initialized, but not filled with data.

  Examples

  The following example initializes the ad_photo of the sample pm.print_media EMPTY table column:
  UPDATE print_media SET ad_photo = EMPTY_BLOB();

• empty fields of digital painting

  Hello

  I am creating a table digital indicator that contains blank fields for all the odd index. For example, (i = 1, 3, 5, etc...) Currently, I have a case structure to determine if the index is odd or even. For a same index, I pass the appropriate values in the function "insert table". For the odd index, I'm not sure what to plug into the 'new items/sub-table"Connector component to generate a value not intialized. Right now I'm wiring the constant infinite to use as an example. Ideally, I want the empty field. Thanks for the help!

  A digital cannot be empty.

  If it's just an indicator, you would simply substitute one string instead. It is possible to look the same. Here's a code option.

  

  Of course, if half of the elements are still the same (empty), it does provide all useful information to the operator. You can view both the items even without gaps. This saves you space in the public Service.

• ContactService returns the empty list of contacts

  Hello people!

  I need to get all the contacts that are there in the phone contacts.

  https://developer.BlackBerry.com/native/reference/Cascades/bb__pim__contacts__contactservice.html#Fu...

  the snippet here returns the empty list of contacts!

  Help!

  Yes, I did!

  Solved it myself... used the address book sample application, following code Weasley worked for me...

  _Service = new ContactService (this);
  QList contacts;
  No filter was specified, so just list all contacts
  ContactListFilters filter;
  contacts = _service-> contacts (filter);

  Browse the list of contact ID
  foreach (const Contact & idContact, contacts)
  {
  Get full details for this contact ID
  const Contact contact = _service-> contactDetails (idContact.id ());
  qDebug()< contact.firstname()="">

  Copy the data into a model entry
  Entry QVariantMap;
  entry ["contactId"] = contact.id ();
  entry ["firstName"] = contact.firstName ();
  entry ["lastName"] = contact.lastName ();

  emails QList const = contact.emails ();
  If (! emails.isEmpty ())
  entry ["email"] = emails.first () .value ();
  }

• How to display the "Add a contact" dialog box with the non-empty fields?

  On the BlackBerry, I want to display a dialog box 'Add a contact' with some fields filled.

  I assumed would work the following code:

  Contact BlackBerryContact = mContactList.createContact ((BlackBerryContact));

  populateSomeFields (contact);

  AddressBookArguments args = new AddressBookArguments (AddressBookArguments.ARG_NEW, contact);

  Invoke.invokeApplication (Invoke.APP_TYPE_ADDRESSBOOK, args);

  but no way. If I invoke with ARG_NEW a completely EMPTY fields are displayed.

  If I invoke with ARG_COMPOSE an IllegalArgumentException is thrown. Is it possible that I can show 'Add a contact' with some informed fields?

  just as an idea: maybe you have to make contact before the opening of the new message notice?
  otherwise it is not possible, you will need to write your own GUI to change the fields in contacts.

• How to hide all the empty fields on a page?

  Hello

  I want to hide all the empty fields but to exclude tables as it messes up the table. He hides this empty cell with borders and the table does not look right.

  My script below works currently it hides all the empty fields on this page.

  Is it possible to exclude on the tables?

  Thanks to all in advance.

  { } / / end of loop for

  Hello

  A table has a class name of the subform, but will have a property of page layout with the value of "table."  If you find one of these, then you sweep that subform.

  But you code seems to have commented, that didn't work for you?

• How can I make the popup with empty fields and create new record?

  I would use a popup create new record.
  I created an af:popup drag and drop a data control VO in jsff. Then, I created a button and place an af:showPopupBehavior. I was able to pop-up window by clicking on the button.
  However, the window filled with information from the record 1. and when I select a record in the table and click on the popup, the popup is filled with this record.
  How can I make the popup with empty fields and create a new record by recording the popup?
  Thank you

  Hello

  You must call the CreateInsert for the underlying ViewObject operation when opening the popup because it does not allow to clear the input field, you must have a new record created

• Select the text to all_views returns an empty string

  My application allows the user to choose between the data provider for ODBC and the data provider for Oracle. (ODP)
  
  When you use the ODBC statement:
  
  Select the text in all_views where view_name = 'MYVIEW '.
  
  Returns the string expected.
  
  If I connect via ODP however it returns an empty string.
  (If I use "Select *" it tells me that the text_length is 154 in this case-, so there are certainly available text.)
  
  I think it has something to do with the fact that the data type is long.
  In both cases I recover data with rdr. GetChars(), that should work.
  
  If I use the dbms_metadata.get_ddl instead of this function, it returns the string (probably because the return type is LONG)
  Unfortunately this function works only for views in the current schema, while the original works of Select for any view.
  (And I don't know what version of Oracle, this feature has been added-I need to support older versions too).
  
  Similarly, if I use one of the XML functions to retrieve the text in XML format it works fine.
  (Again it is probably returned as a VARCHAR2 instead of a LONG.)
  
  The strange thing is that when I created my own table containing a column LONG, I've been able to load and retrieve data without any problem.
  
  The problem seems to be specific to this column in all_views.
  
  Anyone know a solution to this?
  
  Thank you
  Mike

  Did you put InitialLONGFetchSize property appropriately on your OracleCommand object? See if this property does the trick for you?

• Simple? How do you want 'INSERT' function to return the empty space after a field?

  All,
  
  I just have a PET of brain? I have a situation where I have a field that must return a single space, with a value that has a space before and after it.
  
  Example:
  
  In the text == > I'm < field > go to the office. <-notice no space between the two am, < field > and will
  
  I mean if set to FALSE, then "I am * not * going to the office."
  If true, then "I go to the office."
  
  If it is true, I am just RETURN(""); <-this returns a blank space
  
  
  If FALSE, I tried:
  
  RET = 'no '.
  RETURN ("" & ret & "");
  
  This property returns "I am notgoing to UNRWA. <-don't notice any empty space after the 'no '?
  
  I tried
  
  RET = 'no ';
  RET2 = ("" & ret);
  RETURN (Insert (ret2, 3, ""));
  
  Always the same result. What is strange, that is, if I do a RETURN (Insert (ret2, * 2 *, "")); then he comes back "I'm not tgoing to office" <-note the space between the "o" and the "t"?
  
  Ideas?

  I forgot about it. Depending on which version you use, DAL actually supported a function that will make the hard space for you, like this:

  Val = FLOAT (160) & 'not' & CHAR (160)
  Return (Val)

• app.execDialog returns an empty dialog box?

  Hello

  I had this problem for awhile now. I want to open my box customized to the high right after that an alert appears. I did a 'ok' button that calls the dialog box, and I had to insert the code of the complete dialog box in the button using JavaScript 'run '. If I simply app.execDialog the pop dialog box - up would be as expected but all selection fields would be empty. After playing, I gave up and inserted the entire code in the button and it works perfectly. Now, I need to use the app.execDialog again because I have an app.alert which is displayed only if some parts are picked. If the user selects these choices the app.alert appears and informs the user that they cannot choose those and go back and select again which is where I set the app.execDialog to. When you click 'OK' the app.alert to return to the dialog box, it returns to its position and the static text is there and the clusters and windows pop up, but there's absolutely nothing in the popups themselves. Is there a way to get around this? I searched on google and in this forum for a bit and asked my friend a few weeks ago, when it was still there and we found an answer on how to solve this problem anywhere. I can insert an example dropbox program as well. Thank you! I hope this has been descriptive enough!

  No, it should be:

  function getSection1() {}

  var Section1 = {}

  definition of the dialog box

  }

  return the Section1;

  }

• Average ignoring empty fields - something wrong with my script

  Hi I'm trying to calculate an average function for 4 fields with the output values selected from a drop-down list in a form.  The fields are named pk3, pk4, pk1 and pk2.  I have various problems (namely that pk1 is not defined) by the following (and I'm not enough knowledge to know what is wrong).  Any ideas of what can be changed?

  

  Thanks for any help!

  You should check for not an empty string, not a space (drop-down list do not allow an empty string as the value of export) and not a number.

  function myAverageFunction (aNames) {}
  n = number of fields that have a numeric value
  sum = some of the values for the named fields
  var n = 0;
  var sum = 0;
  var v;
  loop through the string array of names
  for (i = 0; i< anames.length;="" i++)="">
  v = this.getField(aNames[i]).valueAsString;
  Search not a string null and not a space and no is not a number
  If (v! = "" & v! = "" & isNaN (v) is false) {}
  n ++ ; County of increment
  sum += Number (v); Add to the sum
  }
  }
  return (n! = 0)? (sum / n): «»;
  }

  Event.Value is myAverageFunction (["pk1", "pk2", "pk3", "pk4"]);.

• We began to receive tons of spam messages that have empty "from" or "sender" field and we can't seem to get the Message filters to trigger on the empty fields.

  I am trying to create a filter that will remove messages that pass through any information in the FROM or SENDER fields.

  I tried: 'contains + [EMPTY]' and ' sender contains ++ [EMPTY] "(where [WHITE] is leave this field empty), and it does not work.

  The filter I use is like this:
  Does not contain a @.
  If this line is empty there is no symbol @, but otherwise he will have this symbol, since each email address there.
  You could do the same for the sender line.
