Index of table based on the value

Is there a built-in method to get the index of an array of \n by its value (JSX). It seems that indexOf does not work here as in javascript...

FWIW, here is the implementation recommended by Mozilla (which has a more robust error checking):

if (!Array.prototype.indexOf) {
    Array.prototype.indexOf = function (searchElement /*, fromIndex */ ) {
        "use strict";
        if (this == null) {
            throw new TypeError();
        }
        var t = Object(this);
        var len = t.length >>> 0;
        if (len === 0) {
            return -1;
        }
        var n = 0;
        if (arguments.length > 0) {
            n = Number(arguments[1]);
            if (n != n) { // shortcut for verifying if it's NaN
                n = 0;
            } else if (n != 0 && n != Infinity && n != -Infinity) {
                n = (n > 0 || -1) * Math.floor(Math.abs(n));
            }
        }
        if (n >= len) {
            return -1;
        }
        var k = n >= 0 ? n : Math.max(len - Math.abs(n), 0);
        for (; k < len; k++) {
            if (k in t && t[k] === searchElement) {
                return k;
            }
        }
        return -1;
    }
}

Is there an easy way to filter a 2D table based on the values in two fields?

Y at - it an easy way to filter a 2D table based on the values of one of the fields. In my attached VI the output array has the following format:

Ident Frame Type bytes TimeStamp data

10:57:07.621 3AD00016 POUVEZ 8 0000000000000000 data frame

10:57:07.622 3AD00017 CAN data frame 8 000005E000000000

10:57:07.624 3AD00018 POUVEZ 8 0000000003300000 data frame

10:57:07.625 2DC00000 POUVEZ 8 0000000000000000 data frame

10:57:07.626 3AD00019 POUVEZ 4 0000030000000000 data frame

I would like to delete all lines that do not have an "Ident" between the values of 3AD00000 and 3AD0001E. So for the data above the fourth row would be removed. The only way I can see to do this is to form a 1 d table. Is there a better approach?

Thank you.

Hi chuck72352,

After you've sorted your data, you can use the function InRange. Combined with a "search in 1 table D", you get the range you really want.

Name of the dynamic property of object in the table based on the value of a variable

I have two paintings of custom class objects
```
var obj1:Object1
var obj2:Object2

var array1:Array = [obj1[0], obj1[1], ...]
var array2:Array = [obj2[0], obj2[1], ...]
```
Object1 has a property named. Name while Object2 has a property named. Title.

Now I have a common function including cab accepts an array (array1 or array2) and the name of property the object ("Name" or "Title") as input and needs to access this name of the property of the objects in the array:
```
function myFunction(arr:Array, fieldName:String)
{
    arr[0].fieldName  = "xxx";
}
```
the problem I have this achievement does not because the code in the function assumes that the property of that object in the table is actually a string "fieldName" while I want to dynamically determine the names of the fields based on the value of this variable, but cannot understand the syntax to do!

Don't know if I'm clear - hope that makes sense... ;-) Thank you

Hey p3pp3r,

I think I understood you. Try the following and see if you get good results:
```
function myFunction(arr:Array, fieldName:String)
{
    arr[0][fieldName]  = "xxx";
}
```
Let me know how it turns out. Good luck!

How to highlight the line of the ADF table based on the value of the column?
Hi all

I use jdev 10.1.3.4. I want to highlight a table row or a cell based on the value of the column.

Lets say, I have a table emp with column empid, empname and sal. I want to emphasize the lines that have sal = 10000.

How can I achieve this? Please help me with this.

Thank you
Abhijit
Hello

You want to highlight the lines? or set a different color for the lines? If it's the second, you can set the inline style based on the salary. (+ Edit: well, never mind, both are same :)) +)

Something like
If you want the entire line to be a different color, you have 2 options.

1. define the same style inline for all columns in the table (good if you want to do only for a single table).
2. create a style class and apply the styleclass based on the value of sal (preferably if you want the same behavior in all of your application).

A few quick hits.

You can merge the two for loops

You have not need one of the constants 1 and 2 in the index table. They will solve automatically when you expand on the index picture, once you have wired to 0 in the column index.

It seems a lot of handling additional table spent unnecessarily.

See below. I did not try to duplicate your code to see how it actually works, but I believe that I have attached will give the same result with less steps.

How better to insert a subarray (line) in a 2D array to the correct index which is based on the value of the first column

Hello

I would like to insert a subarray (line) in a 2D to the correct index table. The position is to say the index value depends on the value of the first column of the table 2d.

As an examlple my 2d array would look like this

230 50 215 255

300 60 270 330

360 20 350 370

And I would like to insert another line (subarray) with the following values

320 40 300 340

This new line should be placed between the second and third rows (this is based on the first column only).

I tried the threshold 1 d function table by taking an 1Dsub array of my 2d array (first column), then using the first of the new line (320) as the threshold. It sort of work, but it does not work when I start the table (IE there is only 1 row) and it seems to not work properly on other occasions (as explained in the help of Labview).

Hopefully the explanation is clear enough for any suggestion. Thanks in advance for the help!

The idea is I have start with a new table and add these lines in the right order every time that the user sets the values Jack

Ahh, so try this.

This will also work with an empty array.

You want to do with this function it is a Subvi.

Make the entries 'table' and 'subarray"on the connector, then 'new array' output.

You can then put this Subvi in a loop with a registry to shift and it will help to add new lines in a sorted order, when they are added.

That is what you were aiming for?

Selectively hiding a row in a Table based on the value of the column

I have a data control that is populated from pro-grammatically, based on the user's selection in the page one of wanting to hide some lines on page 2 at the same time, I don't want to delete the value binding, is there to hide the lines instead of column?

To the table of the ADF, to hide the lines according to the requirement, use the visible property on each of the columns.

For example, if you do not want to display all the lines that have IDs Director like 200 or 201.

Select all radio buttons in a table based on the value of selectOneChoice

Hi all
I have a selectOneChoice with two values
positive i.
II. negative
created vo and am
I have an adfTable with selectOneRadio added as a transitional attribute.
The table is created on the vo.
what I have to do is, when the user select positive of selectOneChoice all the positive radiobutton in the adfTable must be selected and the same for negative also.
I can get the value of the selectOneChoice in the bean using valueChangeEvent.
But I need assistance in the selection of all positive values in adfTable using the selectOneChoice value.
Reference would be useful.
Thank you very much
Kind regards
Jean-Felix

Hi all

Let me post the answer, hope this helps someone.

selectOneChoice

Positive P

N negative

on selectOneChoice event ValueChangeListener

to loop through the rows of the adfTable

If valueChangeEvent.getNewValue () is equal to 'p '.

Assign PositiveRadiobtn attribute 'p '.

otherwise set it to "n".

Kind regards

SQL script to insert values into a table based on the type of user

Hello
I have a requirement where I need to insert (username, groupname) in a table based on the user name.
We have two types of user accounts:
(1) user name, which starts with "DV" example: "DVPATM."
regular user 2) example: 'PATM '.
If the user name begins with "DV" under instruction insert should kick in
insert into < tablename > (username, groupname) VALUES (< username > ' < groupname1 >).
otherwise below insert statement should kick in
insert into < tablename > (username, groupname) VALUES (< username > ' < groupname2 >).
I need to use SQL or stored only procedure.
Please suggest
Thanks in advance

All things being constant, you could use decode/case just for groupname by examining the first character t the user name, for example

insert into (username, groupname) VALUES (, (substr ( , 1, 2) the case when "DV" then else end));

How to create table selectable line or not based on the value of the line
Hello.

JDeveloper 11.1.1.2

Is it possible to make a selectable table row or not based on a value in the line.

That is to say. lets say that the row contains a Boolean LOCKED = TRUE.
This line should not be selectable.

A line whose value LOCKED = FALSE should be selectable.

/ Erik
Erik,

No particular reason to disable a selection of lines for a particular line? If I'm an end user, I would be clicking on the same line of thought again and again my mouse does not ;) (call me dumb :)). How do you differentiate this line (using inlineStyle / styleClass) based on the value of line? In addition, you can disable the other buttons when a row with a particular value is selected (so that the user knows that the selected line is not treatable).

2 definitions of view based on the value of the table
Hi all

Is it possible to have 2 different definitions of each entry of 2 base tables display different, based on the value of the table?

We have 2 tables with similar columns, one with historical and other data was only the latest / greatest according to yesterday (it is populated by ETL from mainframe). Changes made by the java application online is now going into the table containing historical data immediately, but edits made in mainframe comes to the table with the data current next day.

There are 2 products, an is based on the last and largest of the historical table based on cre date and date of mod and other product relies on the table with the current data (not historical).

Tried using joins for these two tables but the performance wasn't good and each product needs table data alone, and so I wanted to eliminate joins.

We wanted to use the same name for the view from the metadata using the shared functionality based on the name of the view.

Is there a way define a view under certain conditions?

It is:

If the value for a particular parameter is 0 then

Select c1, c2, c3 of < historical table > other

Select c1, c2, c3 of < no history table >

Any ideas?
