"10a" wouldn't normally be considered a number. So what sort of number do you expect it to be?
Other than that you can look at the substring and convert/cast functions.

Learning how to read errors and understand them will help you solve your problems quicker by yourself... So lets take a look at the error and classes involved...
The error says:
"Cannor Resolve Symbol: method valueOf(java.lang.Object) in the class java.lang.Integer" and gives you line line where the error occurs: Integer quantity = Integer.valueOf(session.getAttribute("vehiclequantity"));
Now, if we look at the API for the Integer we notice that are are only two valueOf methods: valueOf(java.lang.String s) and valueOf(java.lang.String s, int radix). Not valueOf(java.lang.Object) method.
Now we look at the getAttribute(java.lang.String name) method of HttpSession we see that the method returns a java.lang.Object. Now, you know you put a java.lang.String into that attribute, but the get method returns an Object. This is because you could have put any object in there, an Integer, a String, or some other class instance. But you know it is a String, so you can cast the returned value to a String, so that you will be calling the valueOf(java.lang.String s) method of Integer with the Object returned from the HtttpSession's getAttribute(java.lang.String name) method:
Integer quantity = Integer.valueOf((String)session.getAttribute("vehiclequantity"));

You didn't show any example of your date or time values, butyou might need to add a space between them, like
To_date(Date || ' ' || time,'dd-mon-yyyy hh24mi')

How to Convert array of int into array of byte - please help

I have a 2-dim array of type int and I want to convert it to an array
of byte. How can I do that? Also, if my 2-dim int array is one dimention
can I use typecast as in the example below?
private byte[] getData()
byte []buff;
int []data = new int[5];
//populate data[]
buff = (byte[]) data; <---- CAN I DO THIS??????
return buff;

hi, I suggest you make an array of byte arrays
--> Byte[][] and use one row for each number
you can do 2 things,
take each cipher of one number and put one by one in each column of the row correspondent to that number. of course it may take too much room if the int[] is too big, but that is the easiest way I think
the other way is dividing your number into bitsets(class BitSet) with sizes of 8 bits and then you can save each bit into each column of your array. and you still have one number in each row. To put your numbers back use the same class.
Maybe someone has an easier way, I couldnt think of any.

How to convert VARCHAR to SMALLINT using DB2?

Hi, guys:
I am trying to do some comparison in my sql code:
A.mySmallInt = B.mySmallIntAsString
Unfortunately, mySmallInt is stored as 1, 2, 3, ..... while
mySmallIntAsString is stored as '1', '2', '3'......
I am wondering if there is a DB2 function that can directly
convert a string into an interger or vice versa?
thanks a lot

I believe you can use CAST(B.mySmallIntAsString AS DECIMAL).

How to convert varchar to date?

Hello everyone, I'm new to OBIEE and I'm running into a roadblock...
I have a date that is stored in a varchar2 column in the physical table, like so: 20071225
Silly I know, but that's what I'm dealing with.
Anyway, I want to create a logical column in the business model (using the Administration tool) and convert it to a date so that I can do date arithmetic with it, but TO_DATE doesn't seem to be supported.
In Oracle SQL would do this (I'm using XE):
SELECT SYSDATE - TO_DATE('20050101', 'YYYYMMDD') FROM DUAL
Is there any way to accomplish this same thing in the OBIEE? I see the CAST function, but there doesn't seem to be any way to cast a string to a date?

The original post is 4 years old - I am sure the poster must have figured it out by this time... obiee 11g supports a To_Datetime function though! thanks!

How to convert date in varchar format to TimeZone format?

Hi,
Iam having a date '14-05-08 09:46:35 AM' (in Varchar format). How to convert this date to TimeZone ('IYYY-MM-DD"T"HH12:MI:SS"Z"FX') format?

Thanks in Advance.

Hi,
You would look up the TO_TIMESTAMP and the TO_CHAR functions in the SQL reference manual for the version you don't mention, and make up the solution yourself, rather than asking someone else to do your homework.

How to convert an int variable into Number

Hi all,
I am using Jdeveloper 11.1.1.2
When I insert a row in a entity object I want to create another row in another entity object, but when I am setting the attribute for the new row I have a problem.
Here is the code:
int a = EO1Impl.paramA;
NameEO2Impl.setAttribute("Attribute1", a);
The error is that variable a is an int, while Attribute1 is a Number.
How can convert an int to a Number.
Thank you.

Andrea9,
If a, as you say is an int, and assuming you mean an oracle.jbo.domain.Number,
NameEO2Impl.setAttribute("Attribute1", new oracle.jbo.domain.Number(a));works just fine.

Chioce ch;

how do i convert that int variable i into a String type variable??

Different methods:

How to convert an int number to a byte array, and how to convert back?

Hello, everybody,
Just as the topic, if I have an int number(which should have 32-bit, or 4-byte), how can I convert it into a byte array. And also, how to convert it back.
Thank you in advance!

Alternatively you can use ByteBuffers to do this work for you
// to a Byte Array
int originalInt =...;
ByteBuffer myBuffer = ByteBuffer.allocate(4);
myBuffer.putInt( originalInt );
byte myArray[] = myBuffer.array();
// and back to an int
ByteBuffer myOtherBuffer = ByteBuffer.wrap(myArray);
int finalInt = myOtherBuffer.getInt();
