How to use String to name objects

Hello,
I have an array of 100 Strings and I want to create 100 objects of a Class with same names as the ones in the Strings, is there any way to do it?
I have searched the forum and I think it can be done with a Map Class, but I wonder if there is a more convenient way.
Thanks,
Kostas

Any way other than actually putting them into the map? What did you have in mind? Some kind of zen map, perhaps? :-)
This is exactly the sort of thing a map is for - mapping instances of one class to instances of another; in this case mapping strings to Resources. So this is almost certainly the best data structure.
How you obtain the names and the Resources is another matter. Taking them in as separate arrays (which might have different lengths) may not be the best solution. A better solution might be to make the Resources able to identify themselves so you could add them to the Map and ask them for their names to use as the keys.
Also, I notice that you're creating an array of these resources, but the array will be initialised with 100 (actually, 101 - 0..100) null pointers. This is probably not what you want. And even correctly initialising the array with Resources constructed through the default constructor might not be what you want. You could, maybe, wrap your map with another class which queries the map and lazily creates Resources for you if they don't already exist.

Why and how to use events in abap objects

Dear all,
Please explain me why and how to use events in abap objects with real time example
regards
pankaj giri

Hi Pankaj,
I will try to explain why to use events... How to use is a different topic.. which others have already answered...
This is same from your prev. post...
Events :
Technically speaking :
" Events are notifications an object receives from, or transmits to, other objects or applications. Events allow objects to perform actions whenever a specific occurrence takes place. Microsoft Windows is an event-driven operating system, events can come from other objects, applications, or user input such as mouse clicks or key presses. "
Lets say you have an ALV - An editable one ...
Lats say - Once you press some button you want some kind of validation to be done.
How to do this ?
Raise an Event - Which is handled by a method and write the validation code.
Now you might argue, that I can do it in this way : Capture the function code - and call the validate method.
Yes, in this case it can be done.. But lets say .. you change a field in the ALV and you want the validation to be done as soon as he is done with typing.
Where is the function code here ? No function code... But there is an event here - The data changed event.
So you can raise a data changed event that can be handled and will do the validation.
It is not user friendly that you ask the user to press a button (to get the function code) for validation each time he enters a data.
The events can be raised by a system, or by a program also. So in this case the data changed event is raised by a system that you can handle.
Also, Lets say on a particular action you want some code to trigger. (You can take the same example of validation code). In this case the code to trigger is in a separate class. The object of which is not available here at this moment. (This case happens very frequently).
Advantage with events : Event handlers can be in a separate class also.
e.g : In the middle of some business logic .. you encounter a error. You want to send this information to the UI (to user - in form of a pop up) and then continue with some processing.
In many cases - A direct method call to trigger the pop up is not done. Because (in ideal cases) the engine must not interact with UI directly - Because the UI could be some other application - like a windows UI but the error comes from some SAP program.
So - A event is raised from the engine that is handled in the UI and a pop up is triggered.
Here -- I would have different classes (lets say for different Operating Systems). And all these classes must register to the event ERROR raised in application.
And these different classes for different Operation systems will have different code to raise a pop-up.
Now you can imagine : If you coded a pop-up for Windows (in your application logic) .. it will not work for Mac or Linux. But of you raise a event.. that is handled separately by a different UI classes for Win, Linux or Mac they will catch this event and process accordingly.
May be I complicated this explanation .... but I couldn't think of a simpler and concrete example.
Cheers.

How to use string variable onside quotes

Hi,
i would like to know how to use string variable onside quotes. what i mean is if i have a LOV variable P_STATUS as character string.
and in my PL/SQL function i give a query as
Q AS VARCHAR2(1000) := 'SELECT * FROM EMP
WHERE STATUS = :P_STATUS';
Is this correct. I Know that the above statement works when the LOV is an integer, but when i use a character LOV return value the above statement does not work. how can i get in the character LOV value.
Can someone help me please.
Thanks,

Yes I tried binding all the values separately. It is working, but, I am trying to pass all values by variableBut you can't. The variable is holding a single string value.... that is just 1 value. Your binding are expecting multiple values. You can't bind 1 string value and expect Oracle to magically know how to break your string up into seperate values for the bind variables. What if one of your bind variables actually needed e.g. a comma seperated string as it's value? How would Oracle know that?
You must bind each thing seperately. That's the way cursors work.
, because i have more than 150 tables in which data will be load. that's why i m trying to create a unique procedure to load data one by one table. Otherwise I have to write individual procedures for per procedures.It's a hard life being a software programmer, but somebody's got to do it. Unfortunately there are too many people who try and write "generic" procedures and expect them to just work. I mean why don't Oracle just implement some SQL command so you can do...
execute immediate 'load all my tables';save us all the hassle eh!? ;)
when i write all the columns like
execute immediate (insert_string) using rc1.TOLL_ID, rc1.LANE_ID, rc1.RECEIVED_DATETIME, rc1.LANE_QUERY, c1.EXECUTED_DATETIME
but it is not possible to generate runtime variable thats why I m trying to assign all values to a single variable and use it like
execute immediate (insert_string) using (v_string)
how can I separate the values and ho to use it .Don't use execute immediate. Use the DBMS_SQL package instead and bind your values dynamically with loops to cover all the columns you need etc.

How to use string format in TextInput?

How to use string format in TextInput?
Ex.
HH:MM:SS when typing message appear in 12:34:56 form.
N,NNN when typing message appear in 1,234,567 form.

look up for "Using formatters" in the FB help.
Essentially you'll instantiate a format, NumberFormatter for
numbers for example, and set it's properties like e.g. showing a
thousand separator and then one some event of the TextInput --
valueCommit for example -- you'll do something like:
ti.text = nf.format(ti.text)
this is would also give you opportunity to validate user
input using the same formatter and valid event.

How to use string Variables for data provider names

Really what I need to be able to do is insert the variable
name in this:
dataProvider="{chartXML2.lastResult.month.day}"
I need to replace the "month" with a string variable name
(i.e public var monthName = "January";)
I also need to do the same for the categoryfield as it will
not let me do categoryfield=$String.
In PHP this is incredibly easy to do. You just say
blah=$string . In fact, in PHP you can embed variable names
everywhere. Its very powerful. For instance, in php, for the
dataprovider issue above, i'd just do
dataProvider="{chartXML2.lastResult.$StringName.day}"
and it'd work just fine. Whats the syntax for doing this in
Flex?

You can use bracket notation. But don't. Use a reuslt handler
to wrap the xmllist in an XMLListCollection instance variable and
bind to that.

How to use string functions (substr or ltrim or replace) in OLAP universe.

cost element (0COSTELMNT) - 10 CHAR
Controlling area (0CO_AREA) - 4 CHAR
[0COSTELMNT].[LEVEL01].[[20COSTELMNT]].[Value]
cOST ELEMENT is compounded/prefixed with Controlling Area. I just want to see cost element without conrolling area in the BO report.
Currenlty BO unierse is build based on bex query. I am able to suppress the compounding object in bex query by chaning controlling area to 'No display'. But still BO Webi report displaying compounded values in the report. (Bex report works as expected)
eg: Current display in reort.
controlling area/cost element.
AB00/2222
AB00/2223
AB00/2224
Wanted like below:
2222
2223
2224
I think by using string fucntions (substring, ltrim or replace etc.), I can get the required result. But I am having issues with syntax. I have used like below.
substr(0COSTELMNT ; 5 ; 10)
substr(0COSTELMNT; 5 ; Length(0COSTELMNT)-5)
substr(0COSTELMNT; Pos(0COSTELMNT;"/")+1;10)
ltrim(0COSTELMNT,'AB00/')
What is the syntax for substring/replace functions in OLAP universe. Technical name of cost element in OLAP universe is [0COSTELMNT].[LEVEL01].[[20COSTELMNT]].[Value].
I want to fix this at universe level not at report level as i am using cost element in filter/variable section of the report. Please provide me syntax for above example.

Hi,
In fact SAP BW MDX supports limited string manipulation and only with NAME and UNIQUENAME attributes.
Here are some samples that you can use in universes:
MID([0COSTELMNT].currentmember.NAME,1,4)
LEFT([0COSTELMNT].currentmember.NAME,2)
RIGHT([0COSTELMNT].currentmember.NAME,3)
MID([0COSTELMNT].currentmember.UNIQUENAME ,1,4)
LEFT([0COSTELMNT].currentmember.UNIQUENAME ,2)
RIGHT([0COSTELMNT].currentmember.UNIQUENAME ,3)

How to use String toString?

hey guys,
I've 2-D array and i would like to printout using String toString method. I'v used that method to printout non-array values but I really don't know how to display 2-D array using the String toString method. Can someone please help me? thanks in advance!

I do not understand your question. Please post
whatever code you have and indicate where you are
stuck.I'm sure you're aware of the String toString method which is often used to display the output in different classes without the main method.
I've following code:
public static int bingoCard [][] = new int[SIZE][SIZE];
public BingoCard()   {
        Integer ran = 0;
        for (i = 0; i < SIZE; i ++) {
             if (i == 0) {
                min = 1;
                max = 15;
            } else {
                min = max + 1;
                max += 15;
//             System.out.println("Min: " + min + " " + "Max: " + max);
            // generate all 15 balls in this range
            for (j = min; j <= max; j++) {
                bC.add(new Integer(j));
//             // randomize the 15 balls
            for (j = 0; j < SIZE; j++) {
                while (bingoCard[i][j] == 0) {
                    ran = (Integer)bC.removeRandom(); // get Integer object back
                    if (max <= 15 && (ran.intValue() >= 1 && ran.intValue() <= 15))
                        bingoCard[i][j] = ran.intValue();
                    else if(max <= 30 && (ran.intValue() >= 16 && ran.intValue() <= 30))
                        bingoCard[i][j] = ran.intValue();
                    else if(max <= 45 && (ran.intValue() >= 31 && ran.intValue() <= 45))
                        bingoCard[i][j] = ran.intValue();
                    else if(max <= 60 && (ran.intValue() >= 46 && ran.intValue() <= 60))
                        bingoCard[i][j] = ran.intValue();
                    else if(max <= 75 && (ran.intValue() >= 61 && ran.intValue() <= 75))
                        bingoCard[i][j] = ran.intValue();
//                 System.out.println("Numbers in the card: " + bingoCard[i][j]);
        bingoCard[2][2] = 0;
Now, i want to dipslay the bingoCard[][] using following method
public String toString () { // return that array } instead of using following method which displays it for now
public static void display () {
        for ( i = 0; i < SIZE; i++) {
             System.out.print(" "+ columnTitles[i] +"   ");
        System.out.println();
        for (i = 0; i < SIZE; i++) {
            for (j = 0; j < SIZE; j++) {
                System.out.print(" "+bingoCard[j] +" ");
if (bingoCard[j][i] < 10)
System.out.print(" ");
System.out.println();
Any help would be really apperciated. =]

How to use the column names generated from Dynamic SQL

Hi,
I have a problem with Dynamic SQL.
I have written an SQL which will dynamically generate the Select statement with from and where clause in it.
But that select statement when executed will get me hundreds of rows and i want to insert each row separately into one more table.
For that i have used a ref cursor to open and insert the table.
In the select list the column names will also be as follows: COLUMN1, COLUMN2, COLUMN3,....COLUMNn
Please find below the sample code:
TYPE ref_csr IS REF CURSOR;
insert_csr ref_csr;
v_select VARCHAR2 (4000) := NULL;
v_table VARCHAR2 (4000) := NULL;
v_where VARCHAR2 (4000) := NULL;
v_ins_tab VARCHAR2 (4000) := NULL;
v_insert VARCHAR2 (4000) := NULL;
v_ins_query VARCHAR2 (4000) := NULL;
OPEN insert_csr FOR CASE
WHEN v_where IS NOT NULL
THEN 'SELECT '
|| v_select
|| ' FROM '
|| v_table
|| v_where
|| ';'
ELSE 'SELECT ' || v_select || ' FROM ' || v_table || ';'
END;
LOOP
v_ins_query :=
'INSERT INTO '
|| v_ins_tab
|| '('
|| v_insert
|| ') VALUES ('
|| How to fetch the column names here
|| ');';
EXECUTE IMMEDIATE v_ins_query;
END LOOP;
Please help me out with the above problem.

I Built the statement as required but i need the column list because the first column value of each row should be inserted into one more table.
So i was asking how to fetch the column list in a ref cursor so that value can be inserted in one more table.

Then add a RETURNING INTO clause to the query to have Oracle return the first column values into a collection.

How to use a table name in the select statement using a variable?

Hi Everybody,
I got a internal table which has a field or a variable that gets me some tables names. Now I need to retrieve the data from all these tables in that field dynamically at runtime. So could you suggest me a way out to use the select query which uses this variable as a table ?
Regards,
Mallik.

Hi all,
Actually i need some more clarification. How to use the same select statement, if i've to use the tabname in the where clause too?
for ex : select * from (tab_name) where....?
Can we do inner join on such select statements? If so how?
Thanks & Regards,

How to use get column name.vi in SQL toolkit 2.0?

Due to the vi "get column name.vi" paremeters,no table name has connected to the vi. So, I want to ask how to use this vi for gain one column name of a table. Maybe there are some other ways to solve column name getting.
Thanks.

Thanks!
Error 4101 Description:
Execute SQL - The connection, statement, or query handle you provided is not valid.
I don't just used the toolkit in a while,now, I am developing a irrigation system. For the table field names defined by users,column names must be known before any select operations. Do you have any other good idea about drawing out the columnname parameters?
As you know, a valid DSN and table have been also available. The database I used is Access. The bad thing to me is that there is no any text information gotten. And I think, it may be some problems in connection way which I don't find out.
Really appreciated by your reply.
Could you give me some example in the aspect?
Thank you again.

How to Use String Patterns?

Hai all,
I need help, In my project i am using String patterns.
i need to search a string which contains special characters.
Ex:
1.Abstract{meaning}
I have to search Abstract in this case.
Another case is:
2.Moon
in this i Have to search Moon and
so on.
For this Source Code I had written is:
string input = args[0];
String pattern = "[0-9].*+\\{*\\}";
String pattern1 = "[0-9].*";
string line = "1.Abstract{meaning}";
string line1 = "1.Moon";
if( (Pattern.matches(pattern, line))||(Pattern.matches(pattern1, line1)) )
Pattern p = pattern.compile("\\.");
Pattern p1 = pattern.compile("\\{");
String[] tokens = p.split();
String[] tokens1 = p1.split();
for(int i = 0; i < tokens.length ; i++)
for(int j = 0; j < tokens1.length ; j++)
if((tokens.equals(input))||(tokens[j].equals(input)))
System.out.println(tokens[i]);
System.out.println(tokens[j]);
in this code it matching the 2nd case. it is not matchinf the 1st case.
please help me.
