Trying to create a constraint

Hello, I have the following table tbl_fixed_eq_wks:
FIXED_EQ_WKS_ID     NUMBER(10)
FK_EQUIPMENT_ID     NUMBER(10)
FK_WORKSPACE_ID     NUMBER(10)
The FK_EQUIPMENT_ID and FK_WORKSPACE_ID values have a FK_Lab_Order_ID in their own respective tables. Basically, users can submit a lab order with equipment and workspace requests.
How can I put a constraint on the table above to ensure that the value for FK_Lab_Order_ID matches for the FK_EQUIPMENT_ID and FK_WORKSPACE_ID columns? I want to be sure that the equipment and workspace request is for the same Lab Order request.
Thanks,
Danny

If tbl_fixed_eq_wks has the lab_order_id columns then you can do something like:
ALTER TABLE tbl_fixed_eq_wks ADD CONSTRAINT equip_lab
FOREIGN KEY (fk_lab_order_id, fk_equipment_id)
REFERENCES equipment (fk_lab_order_id, fk_equipment_id);
ALTER TABLE tbl_fixed_eq_wks ADD CONSTRAINT work_lab
FOREIGN KEY (fk_lab_order_id, fk_workspace_id)
REFERENCES workspace (fk_lab_order_id, fk_workspace_id);Otherwise, I think you are porbably looking at some sort of procedural trigger based logic to do it.

Cannot create a constraint beacuse of ORA-00955

Hi !
I was trying to create a constraint on a table after dropping it just in case:
ALTER TABLE NEQResultByChunk
DROP CONSTRAINT pk_neqresultbychunk
OUTPUT: >> ERROR at line 2:
ORA-02443: Cannot drop constraint - nonexistent constraint
ALTER TABLE NEQResultByChunk
ADD (
CONSTRAINT pk_neqresultbychunk PRIMARY KEY

USING INDEX TABLESPACE &&idxtspace
OUTPUT: >> ALTER TABLE NEQResultByChunk
ERROR at line 1:
ORA-00955: name is already used by an existing object
There has to be somethink hang somewhere since using a different name works for the constraint works ok. I could not find this constraint in user_constraints table.
Any idea on where to look for it ?
I already brought dow the DB.
Thanks,
Mike

Why should i delete the index manually?
In most cases, the index will be remove when i delete the corresponding constraint.

Trying to create Netbeans Swing/GUI component

Hello,
I'm trying to create a GUI component from the following code. The main idea is to create a component consisting of a checkbox and a panel. The panel can contain several other swing components. By checking or unchecking the checkbox I want all by components in the panel to be enabled or disabled.
The important thing is that this component should work in the Netbeans GUI designer. I'm using Netbeans 5.5.
My problem is the following:
When adding my swing component to the Netbeans swing component palette and dragging onto a new form, I cannot assign other components to the main panel of my component. Even if I use the Inspector tree to drag components to be children of my component, the mouse icon shows a denying icon.
If I add swing components programmatically, it works.
Can somebody give me an advice what I should change in my code to make it work with the Netbeans GUI designer?
Below you can find the current code of my standalone component. It includes a main() method so one can give it a try.
Many thanks in advance!

Error creating a constraint

Hi to all,
Hi have 2 Schemas and 2 table; the first table in the SCHEMA1 and the second table in the SCHEMA2.
I have tried to create an FK key like this:
ALTER TABLE SCHEMA1.TABLE1 ADD (
CONSTRAINT FK_TABLE1_TABLE2_ID
FOREIGN KEY (TABLE1_ID)
REFERENCES SCHEMA2.TABLE2 (TABLE2_ID)
ON DELETE CASCADE);But this error is returned:
ORA-01031: insufficient privileges
How can resolve the problem ? Wich privileges must I to grant ?
Thanks in advance for Help.

Also you can execute the following (simple version) PL/SQL block:

BEGIN
FOR reg IN (SELECT table_name FROM user_tables) LOOP
EXECUTE IMMEDIATE 'GRANT REFERENCES ON ' || reg.table_name || ' TO ' ||

I am getting a warning message when i am trying to create a host-named sitecollection.

Hi guys,
I am trying to create a host-named site collection. I have created the root site collection. After that i have tried to create customer root site. I have doing this process with the guidance of this link.
http://technet.microsoft.com/en-us/library/cc424952.aspx#section2a
When i tried to create a customer root site. I am getting a warning message
" WARNING: The port specified for the new host header site does not match any known bindings in the specified Web
Application. The new site will not be accessible if the Web Application is not extended to an IIS Web Site serving
this port."
I couldn't when this warning message comes. I tried to bind the server with webapplication which is created for host-named site collection. No use.
Can anyone help me to solve. And i wanna know why this error message comes!!!
Thanks in advance
Rajendran.

First, you shouldn't create a host named site collection on a Web app that has host header named. Doing that implements host names at two different levels and will not work reliably. Second I'm not sure what you mean when you say you didn't
use the FQDN but used just the domain name. A Full url will always be either an FQDN or a shorter Netbios name. If you use a Netbios name it simply assumes the local AD domain of the workstation to create an FQDN as the url There is no way
to use just the domain name. For example, Contoso.com is the domain name. Server.contoso.com or WEbsite.contoso.com are FQDNs. YOu can also use a shorter version that is just server or website, but when those resolve in TCP/IP they would
still resolve using server.contoso.com or website.contoso.com if the workstation where your browser is was in the contoso.com domain. What is the URL for your root site and your host named site?

My family uses a single lap-top as our main internet connection and when we synch our respective I-pods, our I-tunes account seems to wipe-out our playlists, even though we have tried to create separate I-tune accounts. Help!!

My family uses a single lap-top as our home computer and several of us have i-pods that we like to synch, using I-tunes. Although we've tried to create separate I-tune accounts, our i-tunes playlists are getting wiped out when one of us deletes songs on our I-pod and it seems as though I-tunes is not distinguishing our distinct accounts and all i-pods are being synched to reflect the latest i-pod anyone makes on their respective account. It appears as though our distinct I-tune accounts are not being loaded on our lap-top when we sign in and unfortunately, when we're in I-tunes, there is nothing to indicate what account is on the screen. For all the glowing appraisals apple-related products usually receive, we are finding i-tunes and its interface with our respective i-pods to be a very, very frustrating experience.
Can anyone shed some light on this for a family of non-techies? Thx

You need to create separate Windows user accounts if you want to seperate the behaviour of iTunes for each user. That also means separate iTunes libraries for each user.
Windows is a multi-user operating system but you are not using it properly. iTunes is not a multi-user application. No application is. You can't expect it to treat different users differently when they are all using the same computer user account.
Do you understand what I mean?

Trying to create a Mozilla Persona account, but I'm not receiving the confirm credentials e-mail after three tries. Help?

I'm trying to create a persona account for: (Email removed by mod) but when I try to sign up after I've entered my e-mail and new password, I do not receive my confirmation e-mail (after repeated attempts).

The original url you gave me was: http://www.mozilla.org/en-US/persona/ which is in the first screenshot I provided. If I am in the totally wrong place, it is because that is where I was recommended to go.
I cannot login with my email and password, for as I stated in the beginning, I'm not receiving the confirmation email message that validates my email address in order to create a Persona account.

Trying to create a shell script to cut/paste files in finder. Help needed.

I'm trying to create an automator shell script to cut/paste. It'll function exactly like copy/paste. i.e. I'll just copy file/files with command+c like always, but then I'll create an automator which uses the "mv" terminal app to move the files which works exactly like cut paste.
I need some help since I don't know the syntax for creating shell scripts.
What I did so far is to do it in automator with Apple Script which goes like the following:
on run {input, parameters}
tell application "Finder"
set theWindow to window 1
set thePath to quoted form of (POSIX path of (target of theWindow as string))
end tell
tell application "Terminal"
do script with command "mv \"" & input & "\"" & thePath in window 1
end tell
return input
end run
This gets the copied file path from clipboard before, as input, and then recognizes the active finder window as thePath so then executes the mv command for the input file to the thePath window.
It doesn't work as expected since it connects both file/window paths into a single path instead of leaving a space between them so the mv command can't recognize two separate paths.
What's the correct syntax for that line
do script with command "mv \"" & input & "\"" & thePath in window 1
to leave a space between input and thePath under the mv command?
Also this requires the terminal app to be open in the background.
After I get this to work I want to do the exact same thing using shell script within automator, so I won't need Terminal to be open all the time.
And the next step will be to cut/paste multiple files/folders but that should be easy to do once I get the hang of it.

Try using:
on run {input, parameters}
tell application "Finder"
set theWindow to window 1
set thePath to quoted form of (POSIX path of (target of theWindow as string))
end tell
do shell script "mv \"" & input & "\" " & thePath
return input
end run

Trying to create a Invoice based on Order need help Error -5002

the dreaded -5002 error is haunting me too! and I could not find a matching solution for this in the forum....
I need help quickly on this. I am trying to create invoices for some orders so the Base - Target relationship is retained. The orders I pick are all Open (DocStatus   = O and the lines are all Open LineStatus = O)
here is my code

Trying to create a brush to watermark my photos. HELP!!

So, Im trying to create a brush to watermark my photographs, but the 'define brush preset' isnt clickable, but it is clickable with any other photo i try it with. What am i doing wrong? can someone please help me? It's quite frustrating.

Haw large in Pixels is the image?
And quite frankly I would recommend creating a Path and using »Embed Path« instead of a Brush as Actions that include Paths can be more easily transferred without the risk of forgetting the Brushes.

Trying to create a simple example. Need Help!

I'm trying to create a very simlpe examlpe using Swing components to illustrate a MVC architecture.
I have a JFrame containing a JTree and a JButton.
What I'd like to happen is when I click the JButton the JTree model is changed in some fashion and the the view is refreshed due to the models change.
If anyone out there has a simple example of any MVC architecture involving Swing components I'd love to see it.
Thx

Sure, look at any of the Sun tutorials. For example, look in your API documentation for JTree; it has a link to a tutorial about how to use JTree.

I am trying to create a register event for an ActiveX component. The problem I am having is creating the callback vi. When I right click on the VI ref and create the callback vi it is created with the user parameter as a variant. I would like this to be a control refnum. If I open the callback vi and replace the user parameter variant with a control refnum the wire from the callback vi to the VI ref is broken. How do I change the user parameter?

Joe is correct on this one. The callback where designed to take variants as their inputs, so that they are more flexible. In addition Variants are used through out ActiveX programming.
If you have a control reference that you want to pass into the VI, all you need to use is the "To Variant" function in the main VI to turn the reference into a variant. You can then inside the Callback VI you can use the Variant to Data VI to change the variant back to a reference; you simply where a constant of the reference type to the "Type" terminal.
