Application Express :: DateTime Calculations On A Form

Jul 19, 2012

Version of the database you are using: Oracle Database 11g Enterprise Edition Release 11.2.0.2.0 - 64bit Production
Version of Application Express: 4.1.1.00.23

I have a requirement that is driving me stark raving bonkers.

I have a form that a user fills out, it sets the Status to 'Open' and I capture the Date Created On in a hidden field. When someone goes back in to the Form and sets the Status to 'Closed' I capture the Date Closed On in a hidden field. I need to calculate how many hours that it took to close the issue and display it on the form.

I found some javascript that does this

<Code>
<script type="text/javascript">
var msecPerMinute = 1000 * 60;
document.write("msecPerMinute -" + msecPerMinute + "<br />")
var msecPerHour = msecPerMinute * 60;
[code].......

While I can get it to work from dreamweaver I cannot get it to work from APEX. Both of my date fields in my database are defined as:

Type: TIMESTAMP
Fractional Precision: 6
Time Zone: LOCAL TIME ZONE

Application Express :: DML Not Updating Fields With Post Calculations?

Jan 9, 2013

I am running APEX 4.0.2.I am having an issue where I have a page item that has a post calculation

My source used is "Always..."
My source type is "Database Column"

I have tried putting the code in the page item under "Post Calculation Computation", as a dynamic action, and as a Computation Process. It displays properly on the form no matter where I put the code, but when I select Apply Changes it is not updating the database. What am I doing wrong? I have provided a sample of the code, and yes the column name is in the database.

CASE
WHEN :P12_NUM_OF_BOOKED_DEALS>0 AND :P12_DATE_1ST_COMPLETE IS NULL THEN '(2) In Process'
ELSE '(D1) Open Draft'
END

Application Express :: Modify Form Layout Of Existing Application?

Feb 22, 2013

I have to modify the Form layout of an existing application (Application Express 4.0.2.) where the data for each field is retrieved using SQL statements

Presently the form looks something like this and the Data for each field is rendered properly in this layout:

UNIT # :         123456
ADMISSION #: 2012101510         DISCHARGE DATE:                 ADMISSION DATE:
FIRST NAME:   JON                     LAST NAME: DOEFIRST NAME, LAST NAME and UNIT # are all "Display Only" item type.

What I'm trying to do is to move "FIRST NAME" underneath "LAST NAME" and "UNIT #" next to "LAST NAME" This part is very simple. However, the issue I'm having is as soon as the "UNIT #" is moved next to "FIRST NAME", the data for "FIRST NAME" and "LAST NAME" simply disappear

This is how it looks
ADMISSION #: 2012101510         DISCHARGE DATE:                 ADMISSION DATE:
FIRST NAME:                             UNIT #: 123456
LAST NAME:   

I have played around for hours and even created from scratch a new page with a new form using SQL statements to pull the data for each field, only to get the same result.

Application Express :: Tabular Form With Updates In 4.1

Dec 5, 2012

This problem went away for me in 4.2, but I am limited to 4.1 in production. The problem is this: I have three editable columns in my Tabular Form

1) I make a change to column 3 and press submit. The values in columns 1 & 2 (that were not changed) are overwritten with null during the update (submit). Column 3 is saved correctly.

I deleted my tabular form and re-created it thinking that I may have trashed something. But it appears that is the way it works. How do I prevent the unchanged editable columns from being overwritten with nulls?

Application Express :: 4.2 Tabular Form Number Of Rows Bug?

Oct 25, 2012

When I build simple tabular form in APEX 4.2 it displayed 10 rows per page by default. When I changed that number in Number of Rows field to 15 nothing happens. Again only 10 rows per page were displayed. Next field on the right to Number of Rows is Number of Rows (Item). Tabular form works as expected when I use this field and define number of rows with hidden page item. So workaround issue (bug?) is easy. Is this some kind of bug or I miss something obvious?

Application Express :: Updating Fields On A Tabular Form

Oct 1, 2012

I have an application where I'm trying to match skillset supply to skillset demand. We have resources and we have work for resources to do. Resources possess a set of skills. Work requires a set of skills. Skillsets are described by three fields: Domain, Target, Skill. So, we are able to capture the supply of skills in a table:

RSRC_ID (FK to Resource table)
DOMAIN
TARGET
SKILL
PROFICIENCY  (this is the skill level 1 to 5)

The relationship of resources to skill supply is 1 to many. Conversely, work demands skills, and so we capture skill demand in a table:

WORK_ID (FK to Work table)
DOMAIN
TARGET
SKILL.

The relationship of work to skill demand is 1 to many also.

Users assign skills to resources using a master-detail form. It works fine
Users assign skills needed to work also using a master-detail form, and it works fine as well

A view then joins the skillset supply to skillset demand so that assignments can be made only where supply and demand match. This view is used in the LOV below.

I am using a mapping table to capture assignments of work to resources or resources to work. It is a many to many mapping of work and resources with matching skillsets, and it looks like this:

RSRC_ID  
WORK_ID
DOMAIN   (
TARGET   ( These are the skillsets where demand equals supply and are derived from the view and presented in the LOV )
SKILL      (I've created master-detail forms for the two types of assignments. An LOV in the detail form will present qualified resources or eligible work and then return the appropriate RSRC_ID or WORK_ID, but I must also populate the other three fields (DOMAIN, TARGET and SKILL) before I can insert or update the record. Here's the LOV from the form where resources are assigned to work:

SELECT sed.domain||'.'||
       sed.target||'.'||
       sed.skill||'/'||
       sed.skill_prof||'  '||
       r.first_name||' '||
       r.last_name "d",
       r.rsrc_id "r"
FROM   ri_resource r, ri_skill_supply_eq_demand sed
WHERE  r.rsrc_id = sed.rsrc_id
AND    sed.work_id = :P18_WORK_ID

order by 1It is not enough to just match the work to the resource, we must record for what skillset they are matched. I can't seem to see an easy way to populate the three other fields in the tabular form using data that I can retrieve with the LOV.

Application Express :: Maximum Rows On Tabular Form?

Sep 27, 2012

I have a tabular form (report) multi-record. It display only the records 1-15 with pagination to the other pages. When I set the field 'Number of Rows' to 100, it still displays record 1-15 only. I just want to see the complete dataset on one page, without pagination. (There is a filter on it so there will never be more than 100 records displayed)

Application Express :: Tabular Form Row Background Colour?

Jan 29, 2013

I have created a tabular form and have changed some row background colours by using the Column Template sectiom in the report template

i.e

<td #ALIGNMENT# headers="#COLUMN_HEADER#" class="t16data" style="background-color:#FFFF33">#COLUMN_VALUE#</td>

with '#ASSIGNMENT_ID#' = 99 as the condition

This changes the colour but when I move the mouse over the row it removes the colour.

Application Express :: Javascript Function For Tabular Form Changes?

Apr 12, 2013

I have a tabular form with a few columns. THey are ID, date1, date2 and task_name. The task_name is a drop down list of tasks. Upon selecting a specific task, I want the date1 and/or date2 columns to become read only (voided out) so users cannot enter in data. I am working with a tabular form, so I figured I need a javascript function to handle the logic and to call the function in the html elements of the column in the apex environment. This will need to happen dynamically (on click) before the page is submitted. I am more lost/confused on syntax. I know I will need to know the actual column name (coo1, coo2, something like that) of my columns that I will be refering to when I use javascript.

Application Express :: Calling A Procedure From A Tabular Form

Apr 30, 2013

I am new to APEX (well all of Oracle really so only have limited knowledge of PL/SQL etc too) but have created a couple of simple applications via wizards. One of these has a tabular form which works fine for updating records for the table that the form was built over but I need a way to write a record to a second (audit) table as well.

My form is used for cycle counting of items in a location. It originally shows the quantities of all the items in a location and allows the user to make corrections by updating any incorrect quantities to the correct value (this would then update the quantity column in the main table). It then needs to calculate the difference between the old and new value and write this as a record to an audit file (might be a positive or negative number).

do I call a procedure once (on submitting the page) and get the procedure to loop through the changed records writing to my audit file OR do I call my procedure once per changed record on the tabular form, if so how do I know what parameters to pass to the procedure?

I have tried researching this online but can find no easy to follow examples. All examples of code I have seen for tabular forms refer to fields referenced by apex_application.g_f01 or f02 etc - how do you know what items on the page these relate to?
