How to create table containe blob column view?

Hi, I would like to aske any type of blob data
I have data containe blob clolumn type table

I want to create view this table how do?
and

If I created the table view blob column data will be responsible for memory or what because that will cause some performance issues because the table contains enormous data?

Thank you

You must create the view as

  CREATE OR REPLACE VIEW 
  AS
     SELECT col1, col2, col3.....
     FROM    
     WHERE   
     ...etc...

The Act of creating the view will not otherwise the data in the table underlying, all it will do is create a view definition.
Select only the view will select data.

If you don't need to select the BLOB column in the view, then you would not include it in the list of the columns in the view definition.
If your LOB data are stored online, then it may be a significant selection of the view, even if the BLOB column is not indicated in the list of the columns in the view.

How to find DB tables containing specific columns (ORG_ID / ORGANIZATION_ID)

Hi all, I would like to know if someone has developed a script to find all tables containing the columns (fields) specific.

I'm on a migration project where I don't have access to the source of the DB, I just ask for queries and I to reflect all the tables DB containing specific data of organization.
So the first step was to understand used tables and I get them, now I understand what tables have Org_id / Organization_ID and fields of the SOURCE of the LANGUAGE/LANGUAGE (source DB has much set Org and many languages also, so I need to filter the 100total 6ORG_ID and 2 languages of 8 total installed)
Can anyone help?
Thank you

How to create table of the method
Hello-

Could someone please tell me how can I create an af:table with more than one column of an AppsModule method.

When I have a 1 d table return for example:

public String [] createTable()}
String [] str = new String [1];
return str;
}

I can get as a table and a column is created. But how do I get mutiple columns in a table. I want to write a method that when inserted on jsp page create table with multiple columns.

I use ADF 11 g.

Please suggest.

Hello

to do this, you use a matrix, or a list of arrays of objects. The object represents the contents of the line, e.g., person. The Person class then have setter/getter for each property you want to display in a column

How to MERGE when the target table contains invisible columns?

Oracle running on Oracle Linux 6.4 12.1.0.2.0 database:
During his studies of FUSION with invisible columns, I discovered that invisible columns in the target table cannot be read. Workaround seems to be
```
MERGE INTO (SELECT <column list> FROM <target table>) AS <alias>
```
However, the documentation does not seem to allow this. Here are the details.
Test data
```
> CREATE TABLE t_target(
  k1 NUMBER PRIMARY KEY,
  c1 NUMBER,
  i1 NUMBER invisible
)

table T_TARGET created.

> INSERT INTO t_target (k1,c1,i1)
SELECT 2, 2, 2 FROM dual
UNION ALL
SELECT 3, 3, 3 FROM dual
UNION ALL
SELECT 4, 4, 4 FROM dual

3 rows inserted.

> CREATE TABLE t_source(
  k1 NUMBER PRIMARY KEY,
  c1 NUMBER,
  i1 NUMBER invisible
)
table T_SOURCE created.

> INSERT INTO t_source (k1,c1,i1)
SELECT 1, 1, 1 FROM dual
UNION ALL
SELECT 2, 2, 9999 FROM dual
UNION ALL
SELECT 3, 3, 3 FROM dual

3 rows inserted.
```
First try
Please note that I have a WHERE clause in the WHEN MATCHED clause. Its purpose is to avoid the update of a row when data are already correct. The WHERE clause is trying to read the invisible column of the target table.
```
> MERGE INTO t_target o
USING (
  SELECT k1, c1, i1 FROM t_source
) n
ON (o.k1 = n.k1)
WHEN MATCHED THEN UPDATE SET
  c1=n.c1, i1=n.i1
  WHERE 1 IN (
    decode(o.c1,n.c1,0,1),
    decode(o.i1,n.i1,0,1)
  )
WHEN NOT MATCHED THEN INSERT
  (k1, c1, i1)
  VALUES(n.k1, n.c1, n.i1)
...
Error at Command Line : 10 Column : 12
Error report -
SQL Error: ORA-00904: "O"."I1": invalid identifier
```
As you can see, I put a subquery after the USING clause so that 'n.i1' would be 'visible', but this is not enough since the 'I1' column in the target table is always invisible.
Second test
```
> MERGE INTO (
  SELECT k1, c1, i1 FROM t_target
) o
USING (
  SELECT k1, c1, i1 FROM t_source
) n
ON (o.k1 = n.k1)
WHEN MATCHED THEN UPDATE SET
  c1=n.c1, i1=n.i1
  WHERE 1 IN (
    decode(o.c1,n.c1,0,1),
    decode(o.i1,n.i1,0,1)
  )
WHEN NOT MATCHED THEN INSERT
  (k1, c1, i1)
  VALUES(n.k1, n.c1, n.i1)

2 rows merged.
```
Here I used a subquery in the INTO clause thus, and it worked.
Unfortunately, this does not seem to be admitted in the documentation: IN fact refers to a table or a view as schema objects.
My question is:
How can I refer to invisible columns in the target table without creating a new object? My workaround using a subquery solution seems to work very well, but can I recommend if it is not documented?
Can I replace a "inline view" for a view and still be supported?

But the documentation DO ALLOWS not only! You use a view - a view online and those that can be changed in a MERGE statement.

All versions of the doc for FUSION since 9i specifically say this:

INTO clause

Use the INTO target clause to specify the table or view you are updating or inserting into. To merge the data in a view, the view must be updated. Please refer to the "Notes on the editable views" for more information.

Here are the links for the doc. 9i, 10g, 11g and c 12, ALL OF THEM (the last three), except 9i have this EXACT clause above.

SQL statements: INDICATED to ROLLBACK FALLS, 15 of 19

https://docs.Oracle.com/database/121/SQLRF/statements_9016.htm

9i doc does not have this specific quote in the INTO clause section, but it doesn't have that quote a little later:

Limitation of the update of a view
- You cannot specify DEFAULT when refreshing a view.
- You cannot update a column referenced in the ON condition clause.
merge_insert_clause

The merge_insert_clause specifies the values to insert into the column of the target table, if the condition of the ON clause is false. If the insert clause is executed, then all insert triggers defined on the target table are activated.

Restrictions on the merger in a view

You cannot specify DEFAULT when refreshing a view.

If your "workaround" isn't really a workaround solution. You SHOULD use an inline view if you need to reference a column "invisible" in the target table, since otherwise, these columns are INVISIBLE!

My workaround using a subquery solution seems to work very well, but can I recommend if it is not documented?

You can recomment it because IT IS documented.

How to create a trigger on a view
Hi all

I am trying to create a trigger on a view that is used to update a few columns in the base table. As I am new to the trigger, an example will be appreciated.

Thanks in advance.
You would probably be, test the trigger by performing an insert or an update on the view in question and checking that the trigger did what you expected for the base tables.

How to create Table View with even a column name but another Table?

Hi all

I have the problem to create a tableview with the same column name, but in the other table.

Table I: -.

Table - PAC051MPROFORMA

Column - MNR, visitid

Table - PAC051TPROFORMA

How to create a layout three columns of expandable width?

Hi all
Using JDeveloper 12.1.3.
I am trying to create a three-column page layout, two rows, with the column widths of 40%, 10%, 40% and 50% line heights, 50%. If it's important, the middle column could be a fixed width. In HTML, it would be something like below:
```
<table>
     <tr style="height:50%">
          <td rowspan="2" style="width:40%"></td>
          <td rowspan="2" style="width:10%"></td>
          <td style="width:40%"></td>
     </tr>
     <tr  style="height:50%">
          <td></td>
     </tr>
</table>  
```
Any suggestions on how I would go all this in the ADF? < af:panelSplitter > does not have a % value and < af:gridLayout > is not working correctly or the other.
I intend to put the tables completely stretched in the 1st and 3rd columns and a group of buttons in the 2nd column. The end result is looks a bit like a personalized shuttle component.

Hello

Why do you use for the design of ADF page html tags?

for use of three column layout - panelStrtechLayout

She start, Center, end, high and low side and you can set the width in pixels for each facet according to your requirement

Here's the value upper and lower facet width 0px use only 3 columns

How to create an auto adjustment column on dashboard

I have a problem with obiee 1.1.1.7.
I have a dashboard with 2 columns placed side by side and I want to have the column on the left with the minimum size to display the content of the section and the right column fill the rest of the browser window. The left column contains a small guest and the right a PivotTable.
Reach 1.1.1.6 result is trivial: you only need to set the width property of the column on the left to a small number of point (for example 15pt) and Obiee expands the column to match the fast size.
1.1.1.7 I tried all combinations of formatting for column, section options and dashboard, but I can't understand how to achieve the same result: in the same case, I kinda left column but with scroll bar (I don't want scrollbar, I want a column wide enough to display the prompt). in the same case, left column is too large and the guest lies in the middle of the section.
Can someone help me?
Thank you
Luke

@Srini - using specific this column doesn't expand to match the fast size. Wouldn't be better to use "minimum size"? Then the quick column would increase if necessary without a horizontal scroll bar.

@luc - sets the quick column 'size minimue' and give a value of 15px or other. Set the report column to a width of 'size' of 100%. You should be all set.

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).

How to create table of 288 HP push button in the PXI-6509 (3pcs)

Hi all

Need help...

I am a beginner in labview. & her first time use OR for my project.

We must push buttom about 288 HP control panel. We use PXI-6509 (3 pcs)

& I do a code (in tie).

but some time appear as a bug if we push a button push button after all. but some time is ok.

Please correct the code.

Thank you very much...

It seems to work fine for me. What do you mean by "sometimes appear like a bug? How is it not behave like you want.

A few recommendations:

1. There is no logical reason for the node feedback on some of your cables of the error.

2. you can turn some of your groups of buttons in a cluster. This way you can work on changing the value of a cluster and do not have to set up 100's of changes made to the values of the individual controls. You'd also be abe to easily use the cluster to table to transform your cluster of Boolean Boolean rather than building tables table by manually cabling up to 100's of controls.

How to create table of controls (Images, buttons) in ActionScript

Hello!

Could someone help with ActionScript and Playbook SDK?

How can I create a two-dimensional array of controls (buttons, images, text fields) in ActionScript?

And how do I use radio buttons in ActionScript?

Hey,.

keys and parts do not have ID like in html and javascript. That being said, its impossible to do it like that. the best approach is to create your own class that extends the LabelButton (or whatever component you need) and have an id property that is implemented. so, you can set a code personal to her. I've implemented what you asked below. You can apply this to other components as well enough to make changes to the class and modify the extension. Here is the code:

LabelButtonTest.as (main application class):

        {
            super();

            // support autoOrients
            stage.align = StageAlign.TOP_LEFT;
            stage.scaleMode = StageScaleMode.NO_SCALE;

            myButtons = new Array(new Array(), new Array());

            /*

             * set up 10 buttons with their own ID using the constructor
             * for our custom class CustomLabelButton(ID)
            */

            for (var i:int = 0; i < 10; i++)
            {
                var myBtn:CustomLabelButton = new CustomLabelButton(i);

                myBtn.label = "Button " + i;
                myBtn.setSize(100, 50);

                myBtn.addEventListener(MouseEvent.CLICK, onClickEvent);

                myButtons[0].push(myBtn);

            }

            /*
             * We do the same for the second row of buttons, starting
             * with 10

                var myBtn:CustomLabelButton = new CustomLabelButton(i);

                myBtn.label = "Button " + i;
                myBtn.setSize(100, 50);

                myBtn.addEventListener(MouseEvent.CLICK, onClickEvent);

                myButtons[1].push(myBtn);
            } 

            /*

CustomLabelButton.as (our custom label with the ID property button class):

package
{
    import qnx.ui.buttons.LabelButton;

    public class CustomLabelButton extends LabelButton
    {
        private var _id:int;

        public function CustomLabelButton(num:int = 0)
        {
            super();

            id = num;

        }
        public function set id(num:int):void
        {
            _id = num;
        }
        public function get id():int
        {
            return _id;
        }
    }
}

run the code and see how it works. I hope that's what you're looking for. Good luck!
