A small but tricky one -- can u handel it

hi guys
i have a very small but tricky problem
u see i want to get the value of a mathamatical expression (stored in a variable -varchar2) and wants to get the mathamatical value of the expression
eg
declare
a varchar2;
begin
a:='12*12';
etc....
end ;
so here i want to get 144 as the output ..
lets see how u handel it
thanx

Yeap, Execute Immediate is only available on 8.1.?.
Try following.
declare
cursor_no integer;
a varchar2(20);
sqlstr varchar2(128);
rowno integer;
rs integer;
ResVal number;
begin
a := '12 * 12';
sqlstr := 'SELECT ' | | A | | ' FROM DUAL';
cursor_no := dbms_sql.open_cursor;
DBMS_SQL.PARSE(cursor_no, sqlstr,dbms_sql.native);
DBMS_SQL.DEFINE_COLUMN(cursor_no, 1, ResVal);
rs := DBMS_SQL.EXECUTE(cursor_no);
rowno := DBMS_SQL.FETCH_ROWs(cursor_no);
DBMS_SQL.COLUMN_VALUE(cursor_no, 1, ResVal);
DBMS_SQL.close_cursor(cursor_no);
DBMS_OUTPUT.PUT_LINE(ResVal);
END;

you can change the value assigned to variable S1 to whatever operation you need to perform.
DECLARE
     V_HANDLE     INTEGER;
     STMT          VARCHAR2(100);
     S1               VARCHAR2(50) := '12/2';
     RES               INTEGER;
BEGIN
     V_HANDLE := DBMS_SQL.OPEN_CURSOR;
     STMT := 'SELECT '||S1||' FROM DUAL';
     DBMS_SQL.PARSE(V_HANDLE, STMT, DBMS_SQL.NATIVE);
     DBMS_SQL.DEFINE_COLUMN(V_HANDLE, 1, 1);
     RES     := DBMS_SQL.EXECUTE(V_HANDLE);
     LOOP
          EXIT WHEN DBMS_SQL.FETCH_ROWS(V_HANDLE) = 0;
          DBMS_SQL.COLUMN_VALUE(V_HANDLE, 1, RES);
          DBMS_OUTPUT.PUT_LINE('RES = '||RES);
     END LOOP;
     DBMS_SQL.CLOSE_CURSOR (V_HANDLE);

I have to upload files from pagemaker 6.5 but no one can open them.

I have a lot of files (posters, brochures, etc) created in pagemaker 6.5. I try to send them to graphics services but no one can open them. They all want pdf files but acrobat will not convert the p6.5 documents. Any suggestions. Or is pagemaker out lived its usefulness and I should get another program.

Everything you need is on the PM Setup CD. However, PM6.5 is ten years so if you are using WinXP SP3, expect problems.
There's some advice here, but it relates to PM7 and Win2K (which indicates it's no longer current). ISTR that you cannot simply copy/extract Distiller because Adobe are very protective of it.
Installing and Setting Up PM7's Export… Adobe PDF… using the “Application” CD-ROM
and here: Install Distiller from the PM7 application CD

I just bought an imac in september 2012. And i just find out that my microphone is not working. So i did an apple hardware test and with no problems found? I have sound but no one can hear me, not even the computer. Should i bring it back to the store

Before you go through that trouble open About this Mac > More Info... > System Report > Audio and see if the system actually knows it has a microphone. Then you can look into Applications > Utilities > Audio MIDI Setup and see if the microphone is there, select it and make sure the sliders are set to full. Then in System Preferences look for Sound > Input and make sure it shows up there and the sliders are at least half way up. If none of that works do a
SMC RESET
http://support.apple.com/kb/HT3964
Shut down the computer.
Unplug the computer's power cord and ALL peripherals.
Wait 15 seconds.
Attach the computers power cable.
Wait another 5 seconds and press the power button to turn on the computer.
It is the 5 second timing that initiates the reset.
then go through the process of looking for the microphone again as the reset may reenable the mic.

I can dial out on my 4s & can answer calls, but no one can hear me talking? Tried network reset...anything else?

Please help...can dial out & answer calls, but no one can hear me...tried network reset...anything else?

Or you can call 1-800-My-Apple
Sounds like there's a hardware problem with your Mic and you need to get it repaired which can be done either at the store (which is going to get super busy very soon) or you can call into tech support for them to set up the repair for you

What do you do when you can receive a call, but no one can hear you?

Help on locking MySQL tables (many can read, but only one can write) Java

Hi there,
I have a question regarding locking of tables so that only one person can write to the file, but many are able to read the files (or tables entities).
I am not sure if I need to lock the tables in my Java code or do I lock the tables within the MySQL syntax. I'm just a little confused on the matter.
This java code is a working prototype of inserting a customer data into the database and that works fine. I just don't know how to implement it so that only one person can update the table at a time.
Here is the Customer.java code that I have written.
Help would be greatly appreciated, thanks so much.

}In addition, here is my customer sql table.

to the best of my knowledge, this is something related to the database and not the programming. If you'd want to be the only user to read and edit the table, speicify only one user with that privilege and make it password protected. User must enter the password to write to the tables.

BT Infinity is in my area, but no one can get it. ...

Hi guys,
So my exchange (Trillick) has been Infinity activated:
http://www.samknows.com/broadband/exchange/NITR
I also confirmed it with the BT checker and yes it is there. As you can see I live in the middle of some fields!
Problem is I have a friend right beside the exchange, just across the road and he can not get infinity. I live exacly 1.5 miles away and again can't get it. In fact after spending a lot of time entering in everyones phone number from the entire area that I have, no one is able to get it. Now this irks me because I have been told by BT to wait as I will have it before 2012, and according to them it is available in "Some areas from that exchange." Now I don't mind waiting a bit longer but I would really like some accurate information. I see Openreach vans cruising around a lot for the last month or so and still nothing. Towns on both sides of us seem to be up and running for a few months now yet for some reason still nada here.
Finally, as mentioned I live exactly 1.5 miles out the road from the exchange. What are the chances of us EVER getting infinity? I am sick and tired of Plusnet and their 60GB cap. I run a business and that simply is not good enough. As the area is ADSL only they will not raise the limit so I end up with a monthly bill near £80 for broadband alone, and is not sustainable.
Thanks in advance,
J

Hi Webby,
Thanks for the reply.
Results are as follows:
"For Telephone Number 0288** ***** on Exchange TRILLICK
Your exchange is ADSL enabled, and our initial test on your line indicates that your line should be able to have an ADSL broadband service that provides a fixed line speed up to 2Mbps.
Our test also indicates that your line currently supports an estimated ADSL Max broadband line speed of 2.5Mbps; typically the line speed would range between 1.5Mbps and 3.5Mbps.
The actual stable line speed supportable will be determined during the first 10 days of use. This speed may change over time, to ensure line stability is maintained.
If you decide to place an order, a further test will be performed to confirm if your line is suitable for the service you wish to purchase.
Thank you for your interest.
Please note that postcode and address check results are indicative only. Most accurate results can be obtained from a telephone number check.
Note: If you already have a Broadband service enabled on this line and you want to switch service providers, you will need to contact both your current provider and your new provider to get your service changed over new and existing service provider to have this service transferred."
I get about 1.5 mb stable, with fluctuations and drop outs on a daily basis.
As much as I would love to switch over to Option 3, I can't risk it. My current connect is now contract free. Prior to Plusnet I was with AOL years ago and suffered horrible customer service and a horrible connection that went out on the clock at 1.03pm untill 11.06pm everyday. No one could fix it, not AOL and not BT. So I am unwilling to change from Plusnet to BT incase that unknown problem resurfaces. I would rather pay more than have a totally unreliable service, and by switching to BT I would be under contract which is not something I am willing to do when I don't know how unreliable it would be. Plus I had been told I would be getting fibre to the area soon......I will however switch to the first person willing to offer me fibre!
I really wish there was a way to find out my local cabinet and check if I will be getting it.

IPhone 5 works fine with incoming calls and audio books but no one can hear me talk.

I have an add-on blue tooth system in my older Prius and it worked perfectly for a couple of years. I can still receive phone calls and listen to audio books through my radio speakers but all of a sudden my callers could no longer hear my voice so I have to switch the phone audio source to iPhone so they can hear me. This happened when I had the iPhone 4 and has continued with the iPhone 5. Any suggestions on how to fix this?

Hi, Did you test to see if after 2 or 3 mins the phone started working correctly? mine does then it will work for a day or 2 on every call then I have to do the same thing again.

Verizon Crew Causes Outage But No One Can Arrive to Fix for 2 more Days! UNACCEPTABLE

I have tried every other method of contacting Verizon and keep getting nothing but excuses. This morning a crew from Verizon knocked on our door to access our backyard in order to finally take down an old unused pole that has been there for months. We of course let them back there although we hadn't called yet to complain about someone taking down the pole bc we are not the type to complain. For months Phone, Internet and TV were all working fine, no issues, and were fine this morning as well... that is until the crew working on the pole finished what they were doing, and right when they were finishing up their work everything went down, Phone, Internet and TV. We called and did a live chat complaint immediately bc we figured since Verizon had literally just caused the problem they could come fix it. WRONG, they tell us 2 days before a tech can come to FIX VERIZON'S OWN MISTAKE!!!! So a Verizon crew has the time to come ruin our service but after being on hold and talking to someone on live chat we are told they are too busy to get back.
I have a 3 year old, a 1 month old and my Husband is an attorney that often needs to work from home at night and file time sensitive documents with the Courts and this is unacceptable. Tonight he had to go to a family members house to file documents due by midnight tonight and that is where I am able to send this message from now. We would not complain if it was weather related or something out of Verizon's control bc things happen...but this was literally caused by a Verizon work crew in a Verizon truck and now the only answer we get is wait 2 days. UNACCEPTABLE. Due to this action we went from customers who never complain to posting on this just to get some relief and an acceptable answer.

Two user profiles on my iMac but only one can connect to the internet

Hi,
I got the most recent upgrade for Lion and installed it. I have two user profiles on my iMac and now, only one of them can connect to the internet yet both appear to have gotten the full upgrades. Any ideas why this might be happening?
Thanks!!

Does the Account that can not connect to the Internet have full Administative priveleges or is it a Standard Account. If Standard, check to make sure it is allowed to connect.

Website says store clearance item available. Store has two but no one can find them. How's that?

There's a home theater receiver on clearance at a local store according to the website. I called the store since we can't purchase these items online anymore for pickup. The first person I spoke with said they had two. I asked him to check so I didn't make a 45 minute trip for nothing. He comes back a few seconds later and says no but what an awesome deal it was. Strange response. Makes me think he didn't even check, probalby wanting the item for himself. Anyways, I called back a few more times over the weekend because the item is still listed as being available. Everyone says the computer shows two but they can't find them apparently. I don't believe anyone even took the time look. So why is the two items still listed on the website as being available?
Anyways, I really want the item. If would be nice if someone from Bestbuy would help me out with contacting the store to find the two items. If their not available then they shouldn't be on the webiste.

Trusteer Report security for Browsers....I don't know which version of Fire fox I have. Previous one could have Trusteer on it but this one can't and all of my passwords have been compromised as a result. hw can I have trusteer on this one please?

My Bank has made Trusteer raport available to protect all my passwords...and the new version of firefox which installed itself!!!!!! cant support this safty measure whic has now been compromised by MyWebSearch which has also installed itself on my browser...How can I get this feature to run on my browser please!
Regards
Coco

From what I have seen other Trusteer Rapport users post here recently, it isn't compatible with the Firefox 4.0 betas. Most security applications or add-ons typically don't support beta pre-release software. You should still have your older version of Firefox installed yet (if you had one installed), the Firefox 4.0 betas install to their own unique Program Files folder and don't overwrite another version of Firefox.

A small but tricky one -- can u handel it
