Sql help please with, finding all zip codes within a given radius.

I have a table which contains zip, city, state, latdec, longdec, latrad, longrad.
From search screen, if user want, zip code's within 10 mile radius of his zip code, what is the sql. I came up with following sql but it is not correct:
first, find his latdec long dec from his zipcode. Then add radius to those values and do select as follows:
select zip,
latdec, longdec,
city, state, latrad, longrad
from zip_coord
where latdec >= (latdec - 10)
and latdec <= (latdec + 10)
and longdec >= (longdec - 10)and longdec <= (longdec + 10).
I think i need to include radians too, but i'm not able to come up with logical formula.
I would appreciate any help with this topic.
Thanks in advance

gautam ,
u probably need to use oracle spatial option and store geoCodes for each address as a column in the address table . then doing this will be easy

I am not sure I understand the gerography concept, but I think the query should be like this:
select zip, latdec, longdec,city, state, latrad, longrad
from zip_coord
where latdec between( select latdec from zip_record where zip='userinput', select latdec+10 from zip_record where zip='userinput')
and longdec between( select longdec from zip_record where zip='userinput', select longdec+10 from zip_record where zip='userinput')
and latrad between( select latrad from zip_record where zip='userinput', select latrad+10 from zip_record where zip='userinput')
and longrad between( select longrad from zip_record where zip='userinput', select longrad+10 from zip_record where zip='userinput')
Hope, it can help.

Help please with rat maze results code

Hey guys,
Just asking for a little help here. I am trying to finish a java program for a class and I am stuck on a bit of code. I've figured out most of the code but am stuck on this piece of code at the end:
     * Gets the maze time for the rodent.
     * @return String The formatted maze time for the rodent.
    public String getMazeTime()
     * Gets a formatted string with information for the rodent and maze.
     * @return String String with information for rodent and maze.
    public String toString()
Here is the code in its entirety:
* Provides maze results for a rodent.
* @author Ray Waite
* @version December 2006
public class MazeResult
    // instance variables
    private Rat rodent;
    private Time startTime;
    private Time endTime;
     * Constructor for objects of class MazeResult.
    public MazeResult(Rat inRat)
        myRat = inRat;
     * Sets the rodent.
     * @param inRat Rat object.
    public void setRat(Rat inRat)
        This.setRat = new Rat ();
     * Gets the rodent.
     * @return Rat The Rat object.
    public Rat getRat()
return myRat;
     * Sets the start time for the rodent.
     * @param inHour Hour of the rodent's start time.
     * @param inMinutes Minutes of the rodent's start time.
     * @param inSeconds Seconds of the rodent's start time.
    public void setStartTime(int inHour, int inMinutes, int inSeconds)
        this.startTime = new Time(inHour, inMinutes, inSeconds);
     * Gets the start time for the rodent.
     * @return Time The start time of the rodent.
    public Time getStartTime()
        if (this.startTime == null)
            return null;
        Time tempStartTime = new Time(this.startTime.getHour(),
            this.startTime.getMinutes(), this.startTime.getSeconds());
        return tempStartTime;
     * Sets the end time for the rodent.
     * @param inHour Hour of the rodent's end time.
     * @param inMinutes Minutes of the rodent's end time.
     * @param inSeconds Seconds of the rodent's end time.
    public void setEndTime(int inHour, int inMinutes, int inSeconds)
        this.endTime = new Time(inHour, inMinutes, inSeconds);
     * Gets the end time for the rodent.
     * @return Time The end time of the rodent.
    public Time getEndTime()
        if (this.endTime == null)
            return null;
        Time tempEndTime = new Time(this.endTime.getHour(),
            this.endTime.getMinutes(), this.endTime.getSeconds());
        return tempEndTime;
     * Gets the maze time for the rodent.
     * @return String The formatted maze time for the rodent.
    public String getMazeTime()
     * Gets a formatted string with information for the rodent and maze.
     * @return String String with information for rodent and maze.
    public String toString()
I would very much "love" some help. Thanks.
Phil

well, the maze time would probably have something to do with the difference between the start and end times.

Help please...All menus grayed out in CS4...

Premiere Pro used to work and a few weeks ago when I openned it, all of the menu items were grayed out and no editing panel or anything openned. I can't even quit the program. Literally everything is grayed out.
There is nothing I can do with it. I have uninstalled the entire Master Collection using the Adobe Installers and double checked to make sure things were cleaned up by using the Creative Suite Cleaner Tool.I have also attempted to just reinstall Premiere Pro from the disks to no avail.
All other programs in the suite apprear to load and work fine. Only Premiere Pro CS4 does not work.
Any ideas on how to fix this issue? I really need to be able to use the program and can't yet afford to upgrade to CS5.5... so any help would be appreciated.
Thanks guys!
David

Thanks Bill. No worries... Haa, haa. I should have asked MYSELF about the second monitor.
REALLY appreciate the help and care.
Blessings bro.

The second monitor has been an issue with several programs. Photoshop is one too.
There is another thread, where a user was getting the "bing," that a window was open, but could not see it. Sure enough, it was on his second monitor, that had been disconnected. I should have asked if you had ever had a second monitor. I am the "dunce."
Glad that you located the problem and good luck,

Help please with FaceTime. My built in app seems to have disappeared.

If K Penguin's suggestion doesnt work, you will have to go to you iTunes and do a reset, that is if you do not have it in your back up library.

To buy in for delivery in Qatar, you should be starting from the Apple Qatar site:
http://www.apple.com/qa/
Do you have an Apple-ID? if you do, then you should not have to enter your Address again, and may be able to sidestep the US Zip Code issue.

Help please with 2006 Macbook 13inch, for tv hook up.

Help please with 2006 Macbook 13inch, to hook up to tv for streaming. The display works through VGA but the audio isn't working. Got a plug that goes into headphone jack on computer and connects into the audio jack on the back of tv but no sound. I'm not quite sure what the issue is, whether its the wrong plug, the tv, or the computer. Best Buy says this is the right plug and it seems that it would be, but who knows. If anyone has any experience in this, I would appreciate the help!

Make sure those audio plugs are matched with the VGA plug. With your MacBook running something with audio switch between your sources on the TV Component, Composite and such. See if the sound is coming from another source. If so then you've got your audio plugs in the wrong jacks.
Also could you post the make and model number of your TV.

Need Help Please with Flash Professional - No Cursor Change on Buttons/Links in Mac OS

Hi Folks, I am relatively new to Flash Professional but I recently built a very nice flash website with very little problems. I noticed after I uploaded my site to my server, that my mouse cursor did not change from an arrow to a finger on any of my buttons. It did change on the hyperlinks, but not on the buttons. Everything still worked fine but there was no indication to the user that an object was in fact an interactive button. I found this code: button1.buttonMode = true; button1.useHandCursor = true; and inserted it for all my buttons and that seemed to fix everything, I tested the site on firefox, ie, and safari. I am using a PC with windows 7. When I went to check the website on a Mac powerbook, the cursor did not change on any of the buttons and it does not change on any of my hyperlinks either. I have searched all over trying to find a solution and have had no luck. Can anyone please help me with this problem or point me in the right direction? Any advice would be very much appreciated. Thanks so much!!!

Thank you so much for replying! I did in fact let flash professional create the HTML page for the site and have not altered it at all. Would you have any other suggestions as to why it's not displaying my links/buttons on a Mac? I checked out the browsers Firefox, ie, and safari on my pc, but looking thru safari on the Mac, the cursor does not change on any of my links or buttons. Thanks again so much for the reply, nice to hear from a human instead of reading thousands of posts! Very much appreciated!!!!!

Maps with 5-digit zip code boundaries

Hi,
I am trying to display zip-code level data in a map. Someone suggested that I should take a look at Oracle Application Express.
I find it meets most of my requirements. But there is one problem - the maps show 3-digit zip-code boundaries of US States.
However, I want to display data for 5-digit zipcode boundaries. Is there a map available for that?
Or is there a map application present with which I can integrate Apex to display data at 5-digit zipcode level with the boundaries already marked in the map?
Appreciate suggestions and assistance.
Thanks!

Help Please with Wii

I have a Mac OSX 10.6.3 and would like to connect my Wii game to it for the purpose of playing iTunes radio stations from the Wii in a different room than the room the Mac is in. I would like to use either Bluetooth or Airport.....or for that fact I guess any way to connect the Wii to my computer wireless to play music.
Q- Can anyone please help me with how to do this ? What steps do I need to take.
Thank you for any help.

There are no "iTunes Radio Stations" as such. If you're referring to the stations listed in the Radio section of iTunes, as I presume you are, those are independent stations being streamed from some other server and do not need iTunes at all. So if your Wii is capable of accessing streaming radio, it should be able to connect to them directly (if the Wii doesn't have a similar list of stations, looking up the station via the web and then finding their direct link should get you going). How to do that would be a question best taken up on a Wii-related web site, as would your question about how to use your Wii with a wireless network.
Regards.

Sql help please with, finding all zip codes within a given radius.
