Verification of an element in one string from another string
Hi guru,.I have 2 strings separated by commas. Say it like that.
a VARCHAR2 (100): = '1,2,3,4,5,6,7,8,9,10';
b VARCHAR2 (100): = '2,6,9';
My requirement is like I want to check the chain has, if it has all of the b element. I am using the regular expression. But I wasn't able to do.
Kindly help me.
Kind regards
VJ
Hello
I'd probably use the Michaels, but if you want to see how you could do this using regular expressions:
SELECT *
FROM table_x
WHERE REGEXP_LIKE ( ',' || a || ',' || '/' ||
',' || b || ','
, '(,[^,]+,).*/.*\1'
)
;
where "/" is known not either a or b.

FRM-92101 happens when I open one form from another and then close it.
FRM-92101 happens when I open one form from another, check something, display a message to the user and exit the screen to the previous shape.
Version of forms: 10.1.2.0.2. Java: 1.6.0_23. Browser: IE6
When I put forward two messages of 'EXIT_FORM', all right and the second form is closed again to the first shape just like I wanted.
In 9.0 forms, it did not.
It has to do with the fact that I use JRE instead of JInitiator?
Thank you.Take a look by using the built-in NAME_IN forms. You will find the NAME_IN function takes a STRING as parameter. Change your code to:
IF NAME_IN('SYSTEM.CURSOR_ITEM') IS NOT NULL THEN SYNCHRONIZE; END IF;
Hope this helps,

Populating one table from another table
Hi Forum...
I'm trying to populate a table from another table using CFQUERY... I have no problem with the selection of data from the original table, but need help to get the data into the new table. I use MX 6.1 and access as the database server.
The two arrays have domain names identical to the same place, and I don't want to have to code all the column names in the selection and insert command. for example
< cfquery name = "GetData" datasource = 'somename' >
SELECT * FROM AssetTable1 WHERE BarCode = "123456".
< / cfquery >
< cfloop query = "GetData" >
< cfquery name = "InsData" datasource = 'somename' >
INSERT INTO AssetTable2 (xxxx...)
VALUES ("#xxxx... #'")
< / cfquery >
< / cfloop >
I hope this makes sense
Thanks in advance
DaveIf your tables are identical structures and their columns are of the same type and position, and both tables are in the same database, then put everything in a single query.
INSERT INTO AssetTable2
SELECT *.
OF AssetTable1
WHERE bar code = "123456".
If the columns were in different positions, then you should be listed explicitly in the INSERT and SELECT the parts, but you get the idea.
INSERT INTO table1 (col1, col2)
SELECT col1, col2
FROM table2
WHERE all that...Phil

How to refactor (move) an element of one application to another module
Hi all
I have all the components of the business in one module of the application.
Now, I want to have a nested application (NestedAM) under the RootAM module. I created, and finally, I want to move some components from the RootAM to the NestedAM.
How can I do?
I searched the forum, but I don't the have not found.
Thank youHello
In your RootAM.xml tab data, you must exclude the elements that you want to move to NestedAM and include them in the tab NestedAM.xml data model
Hope this helps

Simple enough, but calling one method from another class
Hi all
I know it's pretty simple, even though I do not see where I am going wrong for some reason any. Basically, I have a class that extends JPanel but when I try to call one of its methods in my main class I get an error. The code (I hope) is:
Main.Java
StatusBar.javaimport java.awt.BorderLayout; // ... import javax.swing.UIManager; public class Main extends JFrame implements ActionListener { JFrame frame; public static JPanel statusBar; public Main() { // ... // Add a status bar statusBar = new StatusBar(); mainPanel.add( statusBar, BorderLayout.SOUTH ); setContentPane( mainPanel ); // ... } // ... public static void setStatusBarText( String s ) { statusBar.setStatusText("Test"); } // ... }
The "statusBar.setStatusText ("Test")"; call in the main class file does not work and I get the error:import java.awt.Color; // ... import javax.swing.SwingConstants; public class StatusBar extends JPanel { private int barWidth; private static JLabel status; public StatusBar() { super(); //barWidth = Main.getProgramWidth(); //setPreferredSize( new Dimension(barWidth,22) ); setLayout( new FlowLayout( FlowLayout.LEADING ) ); setBorder( BorderFactory.createMatteBorder(1, 0, 0, 0, new Color(160,160,160) ) ); status = new JLabel("Test", SwingConstants.LEFT); //status.setVerticalAlignment( SwingConstants.CENTER ); add( status ); } protected void setStatusText( String s ) { status.setText( s ); revalidate(); } }
>
cannot find symbol
symbol: setStatusText (java.lang.String) method
Location: class javax.swing.JPanel
statusBar.setStatusText ("Test");
>
Any ideas what I am doing wrong? I created an instance of the class called status bar StatusBar, can I use it to call the setStatusText() method (via statusBar.setStatusText ()) I thought everything is OK, then it does not work? Even if there is an easier way to do what I want to achieve (i.e. to update a JLabel since the 'central' main class file instead of setting the JLabel static and have all classes call him directly), I'd be glad to know where I am going wrong here nevertheless.
Thank you very much
Tristanpublic static JPanel statusBar; public static void setStatusBarText( String s ) { statusBar.setStatusText("Test"); }

>The type of variable statusBar is JPanel. That's all the compiler takes into account. It is not relevant that at a certain point in the program, the type of the object pointed to by this variable is a subclass of JPanel (because at another time, it might be an instance of another subclass or JPanel itself.

How to update one column from another table
Hello
We have some sellers who are defined as employees but without employee_id for some reason any. So I would like to update the correct number of a view of HR records. Here is what I tried:
update of po.po_vendors x
Define employee_id = (select apps.per_people_v7 person_id y)
where y.first_name |' '|| y.last_name = x.vendor_name)
Error received: a row subquery returns more than one line.
If I use this instruction to check, I'm correct employee_id or person_id home:
Select apps.per_people_v7 person_id y, po.po_vendors x
where y.first_name |' '|| y.last_name = x.vendor_name
When I checked/compared with some old posts here, I could not just see where I did mistake. Please notify.
Thank you
Ning
Because for the same vendor id, you have a (employee id) id of the person twice in the target table. As Boneist said "fix data, difficulty of the request, fix the requirement...". »
How many sellers are there in your target table?

How to call a method of one class from another class?
I have two classes, Class1 and Class2 are saying. They are both public. They are located in the same package, and both are important to each other.
I am trying to call a 2 function in Class1, but I do not know the syntax.
I tried:
Class2.godoThisThingNow ();
But it gave me an error 1061, call to a method not defined.
What is the correct syntax for this, and it is even possible in AS3?
Thank you!
You can call a public in Class1 2 method IF Class2 has access to an instance/member of Class1.
for example, in Class2:
var c1:Class1;
.
.
C1 = new Class1();
.
.
.
C1.somepublicMethod ();

Once the element keeps one reference to another. Or you set it to a global var shared by two components.

Copy and paste multiple layers (with objects) of one movieclip to another
Hey guys,.
I'm really frustrated with myself because I believe that this should be easy.
But I was stuck for centuries, hopefully you guys could help out me.
I try to copy the images of 6 different layers and objects (action script, own movements tween, buttons, graphic elements) of one movieclip to another. But as soon as I did this, everyhting seems to have shifted and if I try to reposition elements in the new clip, it seems that I must repeat after each keyframe for each layer.
So my question is
Is a. possible to duplicate a clip, but give it an instance name (a completely new movieclip with the same frames and layers in the same position as the previous)?
B. How can I move multiple objects through the layers and keyframes?
I hope that makes sense.
Thanks in advance for your help.
M.
A. you can create a movieclip instances just by dragging the movieclip on the stage and with actionscript library (if the movieclip is exported for actionscript). all instances of movieclips created in this way will be identical.
You can also right-click on a clip from the library and click on duplicate movieclip and then change the duplicated movieclip. instances created of the split movieclip and original movieclip can be different.
B. I do not understand your question. I understand (I think) your problem. to copy specific layers/frames, just shift-mousedown and drag through all layers and images you need. Don't be shy on the inclusion of the layers and or framework you can remove the latter. then paste it in a new movieclip. remove the layers that you don't want. If you remove all executives of other layers, you must remove the frame of all layers or you will have problems as you described.
