Why String type is unable to get converted to integer type here ?

About SQL function this is written in Oracle Documentation :
"If you call a SQL function with an argument of a datatype other than the datatype expected by the SQL function, then Oracle attempts to convert the argument to the expected datatype before performing the SQL function."But here in this query , i am getting error :
select abs("15") "Absolute" from dual;error :ORA-00904: "15": invalid identifierCan you please tell why "15" is not converted to 15 (integer) type ?

Oracle too called "15" an identifier not a string
Regards
EtbinWhat is the problem if write "15" instead of '15' ? Why Oracle is unable to convert "15" to integer 15 ?As Etbin said, Oracle considers items inside double-quotes to be identifiers, such as column names. If you wanted to name a column "15", then you would have to enclose it in double-quotes, otherwise Oracle would think you were talking about the number 15. If you want to use the 2-character string '15', then enclose it in single-quotes. Single-quotes are how you tell Oracle that something is a string literal; double-quotes are how you tell Oracle that something is an identifier.
I can hear you saying "Naming a column "15" is a really bad idea!" I agree, but Oracle allows people to do lots of really stupid things if they want to. Naming a column "15" would not be anywhere near the worst idea seen on this forum in the last week.

Why string type shared variable takes more time to update in the client

I am using shared variables to share the data across a master and the client PCs connected in a network. (Network published & no buffering)
I have created an integer type shared variable(I32) and a string type shared variable (data size is 60 bytes) in the Master and subscribing to the same in the client PCs. In the master PC, I am modifying the data in this order - update the data in the string type variable and then update the data in the integer vaiable.
But in the client PCs, due to the size difference in the variables, I am receiving the data of the integer first and after that about 3-4 sec later only I am receiving the string data. Can any optimization be done to reduce this latency period? Instead of the string data type any better data type will reduce this delay?
Please suggst. Advnced thanks.

Latency has a lot to do with your network. 3-4 seconds is a long time though. This could also be due to the larget data size of your string. The integer data size is definitaly not 60 bytes. If you're looking for better performance, I would highly recommend looking into Datasocket communication or TCP/IP communication. (There are shipping example for both.)
When it comes to performance of throughput and efficiency, network-published variables are lower on the totem pole.

How do i convert String type to an BinaryEntry Type ?

We have to differentiate between keys that come to Erase method of custom publisher. So, we appended "|" at the end of the key as below
key = "a"; //Actual key that is in Cache
if(//some condition)
newKey = "a|"; //newKey to differntiate
getCache().remove(newKey);
else
getCache().remove(key);
Now, the call comes to Erase method of our custom publisher. Here, we need to perform different operation for the key which has "|" in it. So, we added below code in custom Erase method.
public void erase(BinaryEntry binEntry)
String key = (String) binEntry.getKey();
if(key.contains("|"))
//Need to perform some DB operation here. Then,
//now the key is "a|". we need to remove the "|" symbol and call erase method to remove the actual key ("a") from cache. So we added below code
String newKey = (dnsDomainName).replace("|", "");
//Here the problem is, key is of type String. But, Erase method can take only BinaryEntry type. So, we tried this
binEntry = (BinaryEntry)(binEntry.getContext().getKeyToInternalConverter().convert(key));
super.erase(binEntry); //but it dint work. The entry is not getting deleted from Cache.
//How do we convert the key that is of String type to BinaryEntry ?
else
super.erase(binEntry);
Can someone suggest ?

Can someone suggest ?Excuse me, but you write here totally does not make sense on its own.
1. What class is this method on?
2. Why do you want to use a key in the place of an entry?
If I correctly interpret what you try to achieve, your super-class implementation has to know how to deal with the trailing pipe character as you are never supposed to change the key on an entry, and the entry without the pipe does not exist either.

You mixed Java and Javascript in the expectation that they runs simultaneously.
You are Wrong.
You need to distinguish between the server side languages and client side languages. Java/JSP runs at the server side and produces a HTML page with other client side stuff in it like CSS and Javascript. When the HTML page is finished, it will be sent to the client and then Java/JSP stops. Once the HTML page is arrived at the client, there is no one line Java code in it, only its output/result. Do a View Source in your favourite web browser to see it. Only from that moment on, Javascript runs and/or can be invoked.
Whenever you want to use Java variables in Javascript, you need to print them out as a Javascript variable. Whenever you want to use Javascript variables in Java, you need to invoke a request to the server and pass them as parameters. The request can be either synchronous (a link or a form submit) or asynchronous (ajaxical).

How to convert an int variable into String type

hi everybody
i want to know how to convert an interger variable into string variable
i have to implement a code which goes like this
Chioce ch;
for(int i=0;i<32;i++)
// here i need a code to convert the int variable i into a string variable
ch.add(String variable);
how do i convert that int variable i into a String type variable??
can anyone help me?

Different methods:
int a;
string s=a+"";or
String.valueOf(int) is the better option because Int.toString() generated an intermediate object to get the endresult

Vdisk gets converted to type fixed from expandable during installation to native VHD...

I've tried everyway to Sunday to get work-arounds for this but I'm stumped...
I am breaking into the Windows 8.1 with Update installation after adding my license, and creating a setup to use Native VHD to install to.
I create a vdisk type=expandable, yet at some point during the installation it is getting converted to fixed!
I've tried everything I could think of including formatting it while in the CLI prior to refreshing the volumes, and selecting the VHD disk volume for installation. Yet, after the installation is complete... the "actual" vdisk file should
only be around 11-14GB (regardless of the maximum size during its' creation with diskpart), however... sure enough, after Windows has finished doing its' thing and rebooting... the file ends up being the same size as the maximum property provided during the
vdisk creation with diskpart.... it should not be, it was of type "expandable" >.<
Why is this happening?

Hi,
It's not possible that without any settings, it converts into fixed disk. So how did you configure?
Please follow this guide to check if you have operated that:

File not getting converted to the .EXT type

Hello Experts,
Please help me with an issue ...
Actually Iam doing a mailing program.... in which a newly generated invoices are sent to user....

The file which the user is getting in his mail box should be a .EXT type file....from where he will download the file and upload it in the airtel portal..... from where it been sms to the different number's present in that file......
But the problem is the file is not getting converted to .EXT type and when we are trying to upload it in airtel portal it is saying that file is not in UTF-8 format..
To check whether conversion to file type is working when Iam trying to convert the file in .TXT type its getting converted to text format...but not working with .EXT type when passing 'EXT' in doc_type of FM .
I checked the SCOT transaction if any setting exist but ...didnt found anything useful ...
Please help me to resolve the isuue

Hi joel,
From this thread
Shared Files - problems after upgrading APEX 3.0 to 3.1
i have taken your words,
In my development of the browser cache support for static files, I did notice some unexplainable behavior with IE and Firefox. When uploading static files and then testing them, it almost seemed like the browser would request the resource only some of the time (and then get the HTTP 304). If an Expires tag is not computed, I know Firefox will compute one itself.
As per my understanding, Is it cache_expire should be calculated?
I could not get that line.Could you please explain me.
Thanks in advance.

If you see a dialog telling you the app is not avaiable, then it's not available.
And keep in mind, your credit or debit card credentials must be associated with the same country where you reside.
"Although you can browse the iTunes Store in any country without being signed in, you can only purchase content from the iTunes Store for your own country. This is enforced via the billing address associated with your credit card or other payment method that you use with the iTunes Store, rather than your actual geographic location."

select use as new phone if you want it blanked out.... and select restore from backup if you want it to go back to a previous state.
with the original sim that was in there it will eventually drop the "waiting for activation" messages and will just say No Service... at least thats what mine did

Can a "no wait" latch type gets converts to "willing to wait" latch type?

We have no wait latches like redo copy latch . If it not acquires a latch in its first call, it will make a new request to acquire the latch again.
Is there any limit for making in these number of new requests
or
will it keep on making the new request, till it acquire the latch
or
after so many request, if it does not acquire , this latch will get converted to willing to wait latch type?
Thanks

Verizon is CDMA. Use German GSM SIM to use your iPhone 5. Else call Verizon to address the issue.
