SELECT_LIST_FROM_QUERY_XL in table form

ORA-01445: cannot select ROWID, or sample, a view of join without key - preserved table form w/report and LOV

I create a page "Form on a Table with Report" (APEX 5). Table I has 3 columns: cat_key, item_value, item_description. The cat_key is a foreign key in a table with columns cat_key, cat_value. I created the report and everything works fine.  The page of the report shows my domain cat_key in number, so I want it instead to display the cat_value. I change the field cat_key to a text based on LOV, select my LOV and now when I view the page of report I get the "'ORA-01445: cannot select ROWID from where sample, a join without key preserved table view ' error." The report uses the ROWID as a link to the edit page field.

If I use the same tables and even shared LOV in a report page interactive, it works fine.

What I am doing wrong?

This is a limitation of the IR Apex will rewrite your query to a query that includes the lookup table and the columns. So now you have actually created a query on an inline view, which causes the error. You can see the query apex created when running in debug mode. APEX will join the table of choice with your primary table. For example from one of my IR:

Select 'ID '...

"MSL". "" HIS_COUNTRIES "=> my primary table

) ) b,

(select rv_meaning d, rv_low_value r

of msl_ref_codes_table

where rv_domain = "JOHN".

) L1 = > query My LOV Lookup

...

So, if possible, base your reports and forms on the real primary key, no rowid.

You can also write the IR query with the search yourself:

Select T1.rowid...

of primary_table T1

look_table L1

...

In table form, a dynamic action to disable and set of columns of text

Hello!!

With the help of APEX 4.2.6 with Oracle 11 g R2, someone I work with has a tabular presentation of the need to do the following:

Tables has the following provision:

When the user selects the UOM LOV Dollars, the rate must have related associated text box the amount set to 1.  We currently have JavaScript disable and set the background color, but fo rth elife of me that I can seem to help set the value...

The code we have in dynamic action:

< tt >

ROW_ID = $(this.triggeringElement).attr('id').substr (4);

If (. val() $(this.triggeringElement) == 2)

{

$(«#f04_» + row_id) prop ('readOnly', 'readonly');

$(«#f04_» + row_id) prop ("class", "textinputdisabled");

.Val (1) $("#f04_" + row_id);  < = Here's where we had the question...

}

on the other

{

$(«#f04_» + row_id) prop ("readOnly", false);

$(«#f04_» + row_id) prop ("class", false);

< /tt >

Thank you

Hi Tony

What exactly is the problem here? I have no problem setting the value using the method described above. There is even a '1' in the screenshot above, no doubt, which indicates that the value has been successfully changed.

For ease of improved management, I'd use traversal Dynamics for the form element affected, rather than hard-code the ID (or go with a DA conditional with distinct actions of true/false), but the jQuery code to set the value is the same:

var uom, rate;

uom = $(this.triggeringElement);
rate = uom.closest('tr').find('td[headers="RATE"] input');

if (uom.val() === "USD") {
  rate
    .prop("readOnly", true)
    .addClass("textinputdisabled")
    .val("1");
}
else {
  rate
    .prop("readOnly", false)
    .removeClass("textinputdisabled");
}

(I used a static LOV in the column of the unit of MEASURE, so the value of '$' is 'USD' rather than '2').

The second button is a javascript function call, which is not a summary. the javascript function has a problem

This function has the problem help me correct, whereas we can summarize the amount of lines checked

I have made changes to your page. Check the "Display of Javascript" button, now it shows the correct amount for active items.

Made the following changes:

• The following are removed from the section "run when Page Loads:

Declare
  p_qty          number;
  p_total_qty    number := 0 ;
Begin
for i in 1..APEX_APPLICATION.G_F01.COUNT LOOP
  select nvl(qty,0) qty into p_qty from DURATION
    where id = to_number(APEX_APPLICATION.G_F01(i));
   p_total_qty := p_total_qty + p_qty;
end loop;
    --htp.prn(p_total_qty);
htp.prn('');
apex_application.g_print_success_message := 'Checked total qty:'||p_total_qty  ;
End;

NOTE: The section "run when Page Loads" is intended for JavaScript code to perform the loading of the Page and NOT PL/SQL code.

• The following code removed from the section "Header HTML":

This code was going nowhere, so removed and replaced with code below.

• Added the following code in the section "function and Global Variable declaration:

function enableButton() {
    // code goes here
}

function total_checked() {
   var total = 0; var qty = 0;
   $( 'input[name="f01"]' ).each(function() {
     if ( $(this).is(':checked') ){
       qty = $(this).closest('tr').find('td[headers="quantity"]').text();
       total += parseFloat(qty);
     }
   });
   alert("Checked Total Quantity : " + total);
}

Your APEX_ITEM. BOX calls a JS "enableButton" function, but it has no definition, dummy definition so added.

Kind regards

Problem of update in table form (after validation fails)

Hello.

I have a problem on the shape of tables using APEX 4.2.5.

Application page has a table and a filter element to filter results in a table.

The default value of this element is 0 (zero). This means that all the records are retrieved.

SQL WHERE clause look like where deptno = decode(:P1_deptno,0,deptno,:P1_deptno)

I created testcase: https://apex.oracle.com/pls/apex/f?p=4000

W: nlzoh

SUP: test01

P: test

The application name is A1.

Everything works fine (insert and update), until there are validation error - due to an incorrect value in the column form.

If I add by example in the second row (ename BLAKE) in the column WORK 1111 - so it would look like MANAGER1111 I get a validation error.

Then I remove 1111 so validation would be ok, form insert 16 records (all). I is not updated that one record, it inserts all records.

This allways happens after the validation error.

When there is no validation error, changed row is updated as expected

Insert also didn't happen, when there are value DEPTNO in filter.

So the unexpected result is because of that where would adopt.

So I have two questions.

1. Why does it inserts all lines after the validation error? When there is no validation error, only the changed rows are updated - even if there is no DEPTNO in the filter.

-Why modified column id drop apex?

2. How can I change where clause, so iz will not work correctly.

I hope it's understandable.

Kind regards

Dean

Hello

I created a new shape similar to your condition. His work with no problems.

Please check Page 2 of application A1

Auto generation of serial number in table form

Hi all

I need to implement number line concept as in the Oracle Applications in my Apex a table

(IE):

If I create 3 files in tabular form, it should appear as shown below:

line number must be a number that is automatically generated and must be a database column (ie), we need to show as text (saves the State) column in the form of tables since it is not editable by the user.

"In case I have delete a record, it must be as shown below.

(IE) but I deleted the first record it should automatically change the line number of the second record to 1.

and if I update the tabular presentation by adding another line, then it should appear as shown below:

This functionality is achievable in apex? can someone help me?

I use APEX 4.2.2.00.11 version.

Thank you and best regards,

Madonna

Hey Madonna,

".t20Report" is a cass which refers to your report, I guess. Since you only have a single report, the index will be never greater than 1.

What you want to do is to look at each line of the table in this report and to count the index of each line:

$('.t20Report_tbody_tr').each (function () {}

var i = $(this) .index () + 1 //javscript index is 0, sql is 1

$(this) .find ('td [headers = "ORDNO"] input') .val (i)

})

In table form. No data displayed

Hello world

I have a tabular presentation that uses elements of the application to query data. The user enters the page the first page that contains the calendar by clicking on any date. If the date has no records are attributed to him, the shape of paintings shows them to view/change/remove. If no data is found, it displays the message "no data found".

I start a new session and access the page in a table by clicking the date without any registration. Then, when I go back to the first page (calendar) and click on the date that has affected records, the format of table shows all records. What's really weird is that it does not even show the message "no data found". I don't see the form with the names of column header.

In debugging, I found the following info on the form:

All elements on the page, based on the same query appear successfully, then the query, as well as the item values are correct.

Apex version: 4.0.2.00.07

Please, help me to solve the problem!

Hello everyone,

Just for information, the problem has been resolved. The problem is in the process of apex 'Add Row' that was used to create a new line in a tabular layout on a page load. As soon as I removed from the page and created a dynamic of action that runs the::AddRow() javascript instead of this function, all the records in the report have become visible.

The conclusion: use this process 'Add a line' with caution because it can behave in a strange way.

See you soon,.

Dynamic action on the fields of forms in table form

Hello guys.

That I can see on the form fields in a table, I can't perform dynamic actions. What I want is to have an element of the selection list when in the change event, it changes the values for all the records in the report. For example if I have 40 records in this tabular form and I change the value of 'Open' to ' near the field called State, I want to see this change (status value of 'Open' close ') all rows in this tabular presentation. Is this sensible?

Thank you very much, Bernardo.

Hello Bernardo.

There are several ways to accomplish what you want.

-You can create a PL/SQL procedure to manage an update on all the rows according to the value of the value of your column. I wrote once a blog that can help you with that:

http://vincentdeelen.blogspot.nl/2013/06/custom-multi-row-processing-using.html

-You can create a dynamic action with javascript or jQuery to handle the change event.

The first option is more secure because it is managed by the database, the second is more simple and example adjustable all the entire column for all rows displayed, without the need to refresh your tabular presentation, or your entire page. For course work, you should however have little validation at the end of the database. I also think that it is not possible to set the values of the rows that are not displayed, which would again require some PL/SQL for handling.

If you need help setting up the dynamic action, please set up an example on apex.oracle.com.

Kind regards

Vincent

In table form, addition of line, enter the key

I have a tabular presentation.  The user must enter the number of items; Sometimes one, sometimes thirty. There is a field to display in the report, i.e. 11111 22222 33333... By default, we can enter an element using the ten key pad, press TAB and jump on the add a line button, press ENTER and a new line is created.  But the cursor happened somewhere else in the form.  I would then put the Add button a line sets the cursor to the new line of tables so that the user can quickly add multiple numbers without having to use the mouse to click in each new domain. Thanks in advance...

Also, is there anyway to notify if the user enters a number double?

Hello

I have add to your page sample 3 new JavaScript function in the HTML page header

function validateAndAddNewRow(){

/* get all input tags */
var lInput=$("input[name=f06]");

/* array to hold input values */
var lValues=[]

/* collect input values to array */
lInput.each(function(i){
  lValues.push(this.value);
});

/* get unique values */
lValues=$.unique(lValues);

/* compare input count to unique values count */
if(lInput.length !== lValues.length){

  /* if there is duplicate values */
  /* alert about duplicates and exit */
  alert("Duplicate values");
  return false;

}

/* no duplicates. so we add new row */
addRow();

/* set focus to last row */
$("input[name=f06]:last").focus();

}

And add a line button target has changed

javascript:validateAndAddNewRow();

This seems to work ok in your example when I run with Firefox.

I noticed that on page 3, you have little JavaScript in the HTML Body Page attribute.

You should not write here all the JavaScript functions. You must fix this.

After you have correct this problem and try my proposal in your own environment return message it works.

If it doesn't, the control is there are JavaScript errors, for example by using Firebug.

Kind regards

The documents that I have inserted with SQL do not appear in table form

Useful is fine. I don't know if these things can be changed.

Well, they say: ' it's always the last place you want! "? Some of them can make you tear your hair out.

My approach is 1) to display as much data as possible to ensure that data values are what you think they are. Often, they are not. And, (2) 'believe the error message.
