Can i generate dynamic variables

hi guys
can we generate varibles in a plsql block dynamically ..viz i have some varibles in the data base that are entered by the user and the values are to be calculated at the run time based on some of those varible eg
in database
code formula (varchar2)
a --
b a/2
c b-a*6
etc..
so the problem is to calculate them at run time say based on a (in the above eg).
so scract ur head a little and ....enjoy

You cannot create a table inside a trigger (unless you use an autonomous transaction) since that invloves DDL. Are you certain that you cannot use something like a global temporary table?

Generate dynamic variables

I'm kinda new to JSP, and have the following question:
is it possible to generate dynamic variables in JSP? I searched the WWW, and it seems nobody ever used it. Or I just searched wrong :)
So:
String result = "";
for(int i = 1; i <= 10; i++){
result = "test" + i;
// do something with result here
I would like that the string "result" becomes a variable: test1, test2, test3, ...
I know it is possible in PHP like this:
for($i=1; $i<=$10; $i++){
$result = ${"test".$i};
// here I can do something with the generated variables $test1, $test2, $test3, ...
Does anyone got a solution for this problem? Cause it's driving me crazy ;)

I tried, but I keep getting error's... Anything wrong?

Can we generate Dynamic fields in HANA

Hi Frzz,
I have a requirement, in which i need to generate the fieds based on the value set dynamically. Is it possible in HANA with scripted Calculation view??
Please guide.
Best Regards,
Krishna.

Hello Krishna,
If i understood your problem
Your data looks like this
ActualField
SuperiorField
1
2
1
3
1
4
2
5
2
6
2
7
3
8
3
9
3
your output needs to look like this:
Level 1
Level 2
Level 3
1
2
4
3
5
6
7
8
9
if so, dynamic sql might seem a good option.
My experience suggest there may be a better way...
For Starters ... check out
Window Functions - SQL Reference - SAP Library
Let me know if you see a way forward...or any problems as i am sure there is more to your use case that you cannot reveal on an open forum...So tell me the problem you face if you try it using Window functions.

Dynamic Variable Names

Okay, I just need to figure out how to make dynamic variable
names. In this case, I have a loop, and inside the loop I need to
create a new array for every iteration of the loop. Something like
<cfloop from="0" to="10" index="i">
<cfset LoopArray#i# = Some Value>
</cfloop>
But that doesn't work. How can you make dynamic variable
named? I think it's probably something to do with evaluate or DE,
but I don't know how to use them, and the livedocs make no sense to
me. Thanks!

From your values, you don't want a two-dimensional array
(which although
you're actually building LinkResults as a struct, with the
sequential
numeric keys, it's basically an array), you want an array of
structs, eg:
LinkResults
.player1.moveId
LinkResults.player1.damage
What is "i" actually counting through? IE: from 1-3 things...
which are...
what?

Dynamic Variable Declare

Hi experts,
How can i declare Dynamic variable under loop,
I have Data from CABN Table with Char Name /Data type/Length.
Is there any function module or method where i provide the parameters for declaration.
thanks.

Dynamic Variable Refresh

How can I refresh Dynamic Variables in OBIEE in a Unix enviroment? and can I only refresh a certain list of them?

hi,
Repository variables will be refreshed by giving refresh interval to initialization block.(Specific time scope)
Session variable will refreshed by the sessions management.(Session scope)
Presentation variables will refresh whenever you have the report to run.(Report scope)

How to generate report with dynamic variable number of columns?

How to generate report with dynamic variable number of columns?
I need to generate a report with varying column names (state names) as follows:
SELECT AK, AL, AR,... FROM States ;
I get these column names from the result of another query.
In order to clarify my question, Please consider following table:
CREATE TABLE TIME_PERIODS (
PERIOD     VARCHAR2 (50) PRIMARY KEY
CREATE TABLE STATE_INCOME (
     NAME     VARCHAR2 (2),
     PERIOD     VARCHAR2 (50)     REFERENCES TIME_PERIODS (PERIOD) ,
     INCOME     NUMBER (12, 2)
I like to generate a report as follows:
AK CA DE FL ...
PERIOD1 1222.23 2423.20 232.33 345.21
PERIOD2
PERIOD3
Total 433242.23 56744.34 8872.21 2324.23 ...
The TIME_PERIODS.Period and State.Name could change dynamically.
So I can't specify the state name in Select query like
SELECT AK, AL, AR,... FROM
What is the best way to generate this report?

Using action script 2 how can i send a variable value to a dynamic textbox on a different keyframe?

using action script 2 how can i send a variable value to a dynamic textbox on a different keyframe?

Thanks for your swift response.
That sounds like a good solution, but the code I have on frame 2 is this
timer = 0;
countup = function(){
timer++;
countupInterval = setInterval(countup,100);
If I added the same actionscript to frame 3 which has a dynamic textbox with a variable timer attached wouldn't it just put the timer back to 0? What I want is the last known value that was given when it was in frame 2.
I am thinking of temple run here, I am trying to caculate the total distance(set in the timer variable) from the previous try.
Hope this makes sense.

How to create dynamic variable in Java?

Hi,
I want to create dynamic varible , using ArrayList or Vector. The number of array i dont knwo, so how to create dynamic ArrayList or Vector.
for example:
ArrayList1,ArrayList2,ArrayList3.....n
or
Vector1,Vector2,Vector3 .....n, the n value i will get at run time, so how to create the dynamic ArrayList or Vector or i can use any other Object in java,
Pls provide your input.

1. I have a HashMap with dataok ... fair enough.
2. depending on its size, i need to create variable
to store them.uhm ... why? If you have a variable number of elements in the map then you'd need to generate a variable number of variables (a number, that is not know at compile time, as it seems). Now if you could somehow create those variables, how would you access them? You'd have to generate the code handling them as well ...
Tell us what kind of data you've got and what you want to do with it. There's certainly a better solution to your problem.

Jim - I don't really know, to be honest, but there's clearly a limit to how much APEX can work out at design time about what the query is going to do, especially what columns are going to be generated and how they are going to be presented.
The other problem I've had is that when APEX is able work out what the query is going to do (and generates a set of report attributes to go with it), when the dynamic SQL changes this slightly, the region will break and show an error.
So, for dynamic reports, I would always use the generic option.

Generating dynamic column in planning layout

Hi Guys,
I am new to BPS.. My task is user inputs calendar year thru variable, based on the year it has generate dynamic columns as month of the year entered by the user.
Dnt know i am right or wrong based on the sdn threads. i think i have to create user input variable, and create a FM to read the user input value. Upto to this i can understand, after reading the user input how to calculate the months and generate 12 columns dynamically for each month...
Kindly help me in this scenario..
Edited by: kevin peterson on Jun 6, 2008 5:23 AM

Hi,
I hope you are using calendar year/month and calendar year characteristics. Create an user input variable for calendar year,
create one exit variable for calendar year month.
Inside this exit, read the value of the user input variable, append the year with all 12 months, so u get 12values for this exit variable.
Now keep calendar year in header, restricted by user input variable, create one data column dynamic for calendar year month restricted by this exit variable. This will generate 12columns dynamically.

Formula- for generating a variable discount

I need some help string some ifs together in a formula to dynamically generate a number. I'm not sure how to do it.
I have got as far as this.
=IF(H18<=5, 2)
=IF(H18<=20, 10)
=IF(H18<=50, 20)
but not sure how to link them together or refine the number range in the same field. Any help or pointers appreciated.
Graeme
*_+Detail of what i'm trying to do+_*
+I'm trying to create a formula to do the following:+
+Variable 1 - Field A1+
+(Number of units for sale-can be any number- user entered)+
+Variable 2 -Field A2+
+(variable discount % dynamically generated from variable 1)+
+(discount to be applied later in the spreadsheet)+
+So for example+
+1-5 units get 2% discount+
+6-20 units get 10% discount+
+21-50 units get 20% discount+
+And so on...+
+So I assume I want to use the 'if' and that I need to use a string of several ifs. To dynamically generate variable 2. +
+So assume I need to code the following:+
+If A1 is less than or equal to 5 then return '2' to field A2+
Or
+If A1 is more than or equal to 6 and less than or equal to 20 then return '10' to field A2+
Or
+If A1 is more than or equal to 21 and less than or equal to 50 then return '20' to field A2+

In this sheet I used two soluces.
In cells of column B I inserted the formula :
=IF(A<=0,0,IF(A<=5,2,IF(A<=20,10,IF(A<=50,20,"and so on"))))
In cells of column C I inserted the formula :
=VLOOKUP(A,look_in :: A:B,2,)
From my point of view it's the best soluce because it's easy to enhance it.

Can we generate one report tab for each of the prompt values selected in the bobj 4.0 webi report.

can we generate one report tab which filters
with each prompt value selected in bobj 4.0 webi report.

Hi Shrinidhi ,
It can be achievable with static tabs created for each LOV .But this is not recommended because , object values can change dynamically .
It is good idea to use section on prompt object in the report .With sections great feature available is in larger report it’s easy to navigate using map. It displays the section tree.You can select the particular LOV to navigate.
