How To declare TimeStamp in your code

I am trying to insert date in java application using TimeStamp (java 1.3) to oracle 8i database. But how I want to declare the TimeStamp in my application because I am new in java.
Thank you.

You declare it as "java.sql.Timestamp". There's a JDBC (database) tutorial here:
http://java.sun.com/docs/books/tutorial/jdbc/index.html
Check it out.

Declare Internal Table in Code or in Data Dictionary...Opinions needed?

Is it better to define your internal table and all of its fields in a begin of/end of declaration stmt in your code's data definitions. Or, is it better to create a structure in the Data Dictionary, which means one line of code in your program? Why does one choose the method they prefer?
I am thinking it is best to declare in Data Dictionary, especially since ABAP is now leaning towrds objects. However, I am seeing a lot of field by field definitions in programs. I am very interested in how most programmers accomplish this and why.
Thank-You

I would say that if the internal table is to be used in more than one program, then I would create a structure and/or table type in the ABAP dictionary. If it is to be used in just one program, then I would define it locally.

How can I use a SCH-LC11 device in CHINA which bought from ebay. I am not Verizon customer but I prefer to using your 4G LTE Router . How can I get the unlock code? The device may have a bad ESN but I only use it in CHINA. Kindly looking forward your repl

It's good to read Antoniad's post. It reassures me that I can use my new iPad as an international communication device which is the reason I purchased the thing. However, I called Verizon today (my provider of cellular data) who told me that I can't just pop in a SIM card as you suggested. He also said that he was from the "Pre-Pay" division of Verizon and he was certain that I couldn't do what I planned to do. I was extremely disappointed as I had called Apple prior to buying the iPad and I read the algorhythm on the website for choosing an iPad before purchasing. Those sources were quite specific and the information seemed clear. I would be able to use my iPad to communicate through cellular connections while traveling on the road, literally, abroad. I was told that I could pop in a data card wherever I was, just as you indicated in your message above, and voila I was good to go. The Verizon rep definitively rained on that parade, but said that I might be able to do this if I have a "Post-Pay" account, a different area of Verizon. I haven't had the chance to talk to this division yet, so I looked to Apple's Support for answers. Maybe I will find out that I can use my iPad as an international communication device while traveling on the road afterall, however, it appears I may need a different type of account (Post-Pay), something I was never warned about. Can I switch to this kind of account? I don't know. I have to find out. If you have any information about this issue, it would be good to share since I strongly suspect there are others who bought the iPad for the same purpose that I have.

How to divide your code to many .java files?

I'm having currently over 3000 lines of code and over 70 classes in one file. I would like to divide it so that i would have logical groups of classes. How can that be done. I see only two options here and both of them are bad. Either I do one .java file corresponding to each class, or I put all of them in same file. What can be done to solve my problem?

It is common practice to put one class per file. However with such a large number of classes, such a flat structure could quickly become messy. I don't see any problem with grouping classes within files. You may need to read up on access specifiers (eg; public, private, default access etc) before you split them up, but if your classes are well encapsulated, I can't see any problems ahead.
Another structure you might consider would be to package your classes appropriately. This is a bit tricky to describe, but it's kind of like a directory structure. each package is a self contained logical function of your program. I don't know how well this would suit your purposes.
If you want to split a single file into lots of little ones, you might check out JCreator (www.jcreator.com) as I understand it has a wizard to do this automatically.

How often do you place remarks in your code?

Maybe some of you may consider this a stupid question, but how many times do you place reamkrs in your code.
I usually put a remark nearly in everyline I do in java (or some lines) to describe what is happening. However I am not sure whether doing to much reamrks is seen as a wrong thing!!
what do you people think?

Is that wrong?No, but It isn't the question that I'd ask. I'd
rather ask some of the following ones:
- does it help with understanding the code?
- does it add anything that's not obvious from the
code?
- if something is not obvious from the code, why not?
bad design? bad naming? or simply a complex
algorithm?
- how much overhead does it add to maintaining the
code? (if I change any of those 4 lines, I'll
probably have to change the comment as well, and
chances are that I'll forget).But from time to time you forget what has been made isnide the code, or worse you have to read other people code. All that you say is true, but I believe that having remarks will help other developers reviewing the code after one is gone.

How to declare a dynamic array in java

I have to use a dynmic array of boolean and the size of this array will defiend throuh the run of the program to explian
boolean[][] a;
a=new boolean[number_of_ raw][number_of_ culm];
after the program run the number_of_ raw and number_of_ culm will defind..so if any body know how to declare this kind of arraies in java please help me.

My previous post gives me an idea on how to use ArrayList of ArrayList as dynamic 2 dimensional array.
More info bellow
ArrayList rows = new ArrayList()
ArrayList columns_of_row0 = new ArrayList()
rows.insertAt(0) = columns_of_row0;
ArrayList columns_of_row1 = new ArrayList()
rows.insertAt(1) = columns_of_row1;and so on..
You can't use the code exactly or similar way, it would depend on how this array grows in your application.
But this and my previous post should give an idea on how to insert and retrieve elements from ArrayList when
treated as 2 dimensional array.
Hope this helps.

How to declare class variable with generic parameters?

I've got a class that declares a type parameter T. I know how to declare a static method, but this doesn't work for a static variable:
public class Test< T >
    * Map of String to instances of T.
    * error: '(' expected (pointing to =)
    * <identifier> expected (pointing to () )
   private final static < T > Map< String, T > MAP = new HashMap< String, T >();
    * Get instance of type T associated with the given key.
   public final static < T > T getType( String key )
      return MAP.get( key );

I'm trying to create a generic polymorphic Factory class that contains boilerplate code.
I don't want to have to rewrite the registration code every time I have a different return type and parameter.I haven't seen a case yet where that is reasonable.
If you have hundreds of factories then something is wrong with your code, design and architecture.
If you have a factory which requires large number of a varying input types (producing different types) then something is probably wrong with your code and design.
A reasonable factory usage is one where you have say 20 classes to be created and you need to add a new class every 3 months. Along with additional functionality represented by the class itself and perhaps variances in usage. Thus adding about 3 lines of code to one class is trivial. Conversely if you have hundreds of classes to be created by the factory and you are adding them daily then it is likely that
1. Something is wrong with the architecture which requires a new class every day.
2. You should be using a dynamic mechanism for creation rather than static because you can't roll out a static update that often.
More than that the idiom that leads to factory creation is different for each factory. A factory that creates a database connection is substantially different than the one used in dynamic rules logic processing. A generic version will not be suitable for both.
Actualy the only case I know of where such a factory might be seem to be a 'good' idea is where someone has gotten it into their head that every class should be represented by an interface and every class created by a factory (its own factory.) And of course that is flawed.

How to declare a bind variable with 'date' data type in command prompt?

how to declare a bind variable with 'date' data type in command prompt?
sql>variable q date;
when i execute it show list of datatypes

Hi,
As Lokanath said, there are no DATE bind variables.
You can use a VARCHAR2 bind variable, and convert it to a DATE in your SQL statment.
If you're using SQL*Plus, consider a substitution variable. It won't be as efficient as a bind variable, but it will be as convenient.
For example:
DEFINE first_entrry_date = "DATE '2010-06-20''
SELECT   ...
WHERE   entry_date >= &first_entry_date
{code}

Hi,
i'm not quite sure where ct_result is first introduced. There seems to be no declaration?
Judging by the name-prefix, it would be a changing parameter of which form?
Where is it populated, since you intend to loop it?
And then, from which hat do you draw wa_result? it neither seems to be declared nor is there an assignment of values.
On the other hand, you're trying to change table ct_result directly by altering a field of an assigned field-symbol. Why do you feel it necessary to follow up with a modify statement?
After so many question-marks i have lost the point of your initial question.
Maybe, you can start with a short description of your intention and a more accurate code-snippet.
Best regards - Jörg

I suppose that some connections were closed well and others didn't close in the right form and use cache timeout.
Nevertheless even now I don’t know how to correct the message of connection:

How to declare a list of dates

Hi,
I have an item which type is "Display as text based on LOV". I put in the source section under the type "Pl/SQL function body" the following pl/sql function :
DECLARE
X VARCHAR2 (4000);
Y DATE ;
BEGIN
X := 'SELECT distinct(TO_CHAR(DATE1, ''YYYY'')) d, (TO_CHAR(DATE1, ''YYYY'')) r FROM SIVOA.EVV_'|| :p4_site ||' WHERE CLEF_VAR = (SELECT CLEF_VAR FROM SIVOA.SITE_DEBIT_RIVIERE WHERE SITE ='''|| :p4_site ||''')
order by d';
EXECUTE IMMEDIATE X INTO Y;
RETURN Y ;
END;The problem is that I get an ORA error.
ORA-00932: types de données incohérents ; attendu : - ; obtenu : -
I know that I have declared Y as a date and that what is returned by my function is a list of dates. I don't know how to declare a list of dates or whatever to be returned as a lis of values. Hope I am clear, sorry for my english.
Thank you for your kind help.

Hi Tony
You hare very patient with me thank you !!!
Let me clarify well.
I am trying to create a list of values based on dates contained in a table. This list of values should contains the "years". If the table contains data for the years 2005, 2006, 2007, then the list of value should return :
2006
2007
2008
As I want a list of value I need to have a display and a return value. The name of the table is 'dynamic' It is the item P4_SITE that contains a part of the name of the table. This is why I am usins PL/SQL, because I don't know the name of the table in advance.
I have not seen any way to put a pl/sql statement in the List of values definition of the item. Thi s is why I try to make a LOV with the SOURCE of the item.
Hope I am clear.
