How to update a field date in a form based on a table
I created a form (FOO). This form has a column called LAST_UPDATE_DATE. I want to update the value of the column with the date and time when the user makes a change to the line. I'm running into some difficulties doing this work.I updated the source of the default database column type this field. The value of the source or the expression has the value "LAST_UPDATE_DATE". I also set the default value (TO_CHAR (SYSTIMESTAMP, "DD-MON-YYYY HH24"); The first time, this line is being updated field is updated correctly the current date/time. However, on later changes to the line, the field does not have the most recent date/time value.
Any recommendations on what I am doing wrong or what might be the right way to address the issue?
Thank you
John
John,
You can also just do a process that fires after the automatic line, which defines the update_by and the update_date of check processing.
or conversely, you might have a process just before you automatic line treatment for set the update_time systimestamp element fire. in this way the actual insertion/update is managed by the transformation of the auto line.
In addition, if you are worried about forgetting the trigger, I always do an installation script and add new items to it because they are necessary. Then, you add the installation script in your support items if she lives with the application.
See you soon,.

How to create a field date in my Contact form. Ideally, it would offer a timetable for the user to choose from.
Hello
You cannot add a calendar field in Muse. However, if you decide to host your site on Business Catalyst, you can add the Date field to your form in the form Builder Web of BC and then add the form code to your Muse site using the feature to insert the HTML code.

Form based on a Table, only updated authorized, form does not display the data
Hello
I created a form based on a Table by the corresponding wizzard. The table has only one line. The shape didn't create or delete buttons, only update & Cancel is allowed. The PK (id field) is hidden and it takes the value of a database trigger when insert (in fact never is apllied because there is no Create).
When the form is called it is already displayed in update mode, with cancel button allowed but not data in the fields. Line seems ok, session data available null to variables/positions. No idea why this is happenning? I expect to HAV the data in the form fields.

Update the field Date according to the date of another field
Hi I have a field called "contract end Date" which I update manually according to the contract, and a field called "notify contract end Date" I want to be updated automatically with the "end of contract date" - 45 days.
Is this possible via workflow? can someone give me the syntax that works? If I want to manually insert the value of the field 'Date to end the contract to notify' it will overwrite it?
Thank you, DavidHello!
Create your workflow on your object type, select the before saving the trigger modification event, put the following condition:
[< contract end date >] <>MEADOW ("< the contract end date > '")
And in action, update the field End Date of the contract to notify with end Date of contract - 45 and check the replacement value. You contract end Date field must be with the type date.
I hope this will help, do not hesitate to ask for more!

How to move the fields in the contact forms
I'm having a devil of a time of formatting of my muse contact form. I had "change all" checked when I click on the widget to the entire form. First of all, when I go to one of the fields and in the name field options, I checked all the fields - required, display the quick text, etc-, but the text prompt does not appear. In addition, because I chose to edit together does all fields ' required? Then, the big one - I searched and seen so many tutorials on this but I have not met that tells you how to move text fields. Phone-work is down and I wanted to move it to the top. And then when I added a custom field I wanted to add 'Profession' and place it under 'Name' but will have a hard time with that. Anyone out there who can help me? Frustrated!
Hello
Selection in Muse form Widget works like other widgets in the program. You enter more deeply into the hierarchy every click: so with the first click you select the form, with the next click you select the form field, with the next click you select label/Input/button/SMS text according to what you click.
You can select and move individual form fields or several fields of form (shift + click to add to the selection) wherever you want. There is a Form of Message field that isn't visible in States other than the Normal State - pay attention to move upward if you moved everything upward, but still see that your form is larger than expected with an empty space at the bottom [more often than not - the Message form field is the culprit]. Just go to any State other than Normal with the chosen form and you will see this field.
Hope that clarifies how you can customize the form Widget in the Muse.
Thank you

How to set CurrentDateTime field date. MinValue in valueChangeListener
Hello
I use Jdeveloper 11.1.1.2. I dropped a view as a table object and a validation button below the table for the jspx page and in this table, I have 2 columns is selectBooleanCheckbox
and another date. MinValue field.
My requirement is each time a person change the value that is to check/uncheck true/false checkbox, I need to for the column Date.MinValue currentDateTime.
I'm trying this way
< af:selectBooleanCheckbox value = "#{row.bindings.DocumentFlag.inputValue} '"
label = "#{bindings." OTMEmployeeCoursesView1.hints.DocumentFlag.label}.
required = "#{bindings." OTMEmployeeCoursesView1.hints.DocumentFlag.mandatory}.

ID = "it2' autoSubmit = 'true '.
valueChangeListener = "#{backingBeanScope.backing_EmployeeTrainingDocuments.setDateonValueChange}" >

String LastUpdateDate = rowData.getAttribute("LastUpdateDate").toString ();
String DocumentName = rowData.getAttribute("DocumentName").toString ();
String DocumentFlag = rowData.getAttribute("DocumentFlag").toString ();
System.out.println ("value DocumentName is:" + DocumentName);
System.out.println ("value of DocumentFlag is:" + DocumentFlag);
java.sql.Date Date.MinValue = new java.sql.Date (System.currentTimeMillis ());
SimpleDateFormat formatter = new SimpleDateFormat ("" dd/MM/YYYY HH: mm: a "");

can someone help me how to set the value currentdatetime in valuechangelistener.
Thank you
HeraldSuggestion: assuming you are using ADF BC, this would be better done at the level of the Entity object. You just when the Set accessor for the DocumentFlag attribute is called, also call the setter for the attribute date setting the value to the current date/time.

How to update a field value masked and send it to the DB in the ADF?
Hello
I use JDev 11.1.1.2.0 and ADF 11 g.
I provide an update screen where one field is a field of State. This is directly related to DB tbl as well.
When col1 is null status = 'A '. Where col1 has the status of invalid value = 'R '. In both scenarios, I do need to update the status of 'B '.
The problem is that I don't have to display this status column to the user value. So on click of the button on the screen 'save', I must capture the value in col1 is entered by the user and update the status field.
How can this be achieved?
Thanks in advance.You can do model level...
1 generate a ViewRowImpl class with accessors for your VO
2. call setStatus method in your method of setCol1.You can check the conditions he what is the value entered in a method
I guess I have the status column in the Emp table and I want to change the value when someone changes the salary > 5000 then status will be Y
public void setSal(Number value) { setAttributeInternal(SAL, value); if (getSal().compareTo(5000) == 1) { setStatus("Y"); } else { setStatus("N"); } }
hope this helps

How to display a field date null?
We have a few million chronogram and former AAU transformed system and many dates were null. These appear as 01/01/53 (January 1, 1753) and requirements is to display spaces. It seems so simple but I can't think about how do and can't find that he documented in the forum anywhere. Any ideas?
BillTake a look in the database directly. Your migrated data will have the date in it. Clean data as Ryan mentioned a few posts ago. (Content Server does not display null values in the date "01/01/53" string, but as a vacuum.)

How to customize a field date as today?
Hello
Can I customize a date field as the current day? Then when I opened the PDF file of any day, it always gives me today.
Thank you
You need the appropriate format and the date object chain.
Download current date object system
var oNow = new Date();
Set the value of date formatting string
Event.Value = util.printd ("mmmm dd", oNow);Do not forget that this date is not a number but many numbers of the date object can be obtained, as the month day, year, day of week, zone offset.
Specifying the date is a much more complex issue.

How can I filter the data and display it in the html table?
Hello
How do I filter data that contains the database table and already displayed in html table, then when the user write a data to filter or search, it will automatically display the data in html table. ?
can someone help me to do this? Here is my php code for the table that will display the data:
<?php $servername = "localhost"; $username = "root"; $password = "pass"; $dbname = "ses"; // Create connection $conn = new mysqli($servername, $username, $password, $dbname); // Check connection if ($conn->connect_error) { die("Connection failed: " . $conn->connect_error); } $sql = "SELECT No, Calon, ID, Jurusan FROM candidates"; $result = $conn->query($sql); ?> <?php if ($result->num_rows > 0) { echo "<table > <tr> <th>NO</th> <th>Candidate</th> <th>ID Number</th> <th>Programme</th> <th>Edit</th> <th>Delete</th> </tr>"; // output data of each row while($row = $result->fetch_assoc()) { echo "<tr> <td align='center'>" . $row["No"]. "</td> <td>" . $row["Calon"]. "</td> <td>" . $row["ID"]. " </td> <td>" . $row["Jurusan"]. "</td> <td align='center'><a href='main2.php?edit=".$row["No"]."'>Edit</a></td> <td align='center'><a href='delete.php?del=".$row["No"]."'>Delete</a></td> </tr>"; } echo "</table>"; } else { echo "0 results"; } $conn->close(); ?>
hope someone can help me with this.
Thank you.
You must first create a search form for the user to enter a search word:
Then create a page named search_page.php and insert the following code into it and save it. The code in red below Gets information from the search form field name = "Calon" and the SQL query finds in the "Calon" database field for a game.
<>
$servername = "localhost";
$username = 'root ';
$password = "pass";
$dbname = 'his ';
Create the connection
$conn = new mysqli ($dbname, $servername, $username, $password);
Check the connection
If {($conn-> connect_error)
Die ("connection failed:".) $conn-> connect_error);
}
$Calon = trim($_POST['Calon']);
$sql = (' SELECT no, Calon, ID, Jurusan candidates WHERE Calon = "'.") $Calon.' » ") ;
$result = $conn-> Query;
?>
<>
If ($result-> num_rows > 0) {}
