What is the BO 6.5 bouser variable equivalent in BO XI R2?

We use <bouser> variable in BO 6.5 to implement row-level security.
What is its equivalent in XI R2?
Thank you.

It's BOUser.
But you might try DBUser as well - it' configurable for an Enterprise User in the Central Management Console, as "Secondary Credentials" for a Universe.

What's the maximum size a varchar2 variable can hold for and NDS Stmnt?

What's the maximum size a varchar2 variable can hold for and NDS Statement? I read that NDS is good for doing EXECUTE IMMEDIATE on statements that aren't too big. The 10g PL/SQL manual recommends using DBMS_SQL for statements that are too large, but it never gave a limit for what too large was. Does anyone know offhand?

The limit is the same as the length of varchar2 variable within PL/SQL - that is varchar2(32767).It's not documented, but intermediate concatenation result can hold up to (64k-1) :
Connected to:
Oracle9i Enterprise Edition Release 9.2.0.8.0 - Production
declare
part1 varchar2(32767) := rpad('begin null;', 32767);
part2 varchar2(32767) := lpad('end;', 32767);
begin
dbms_output.put_line(length(part1 || ' ' || /*' ' ||*/ part2));
execute immediate part1 || ' ' || part2;
end;

What is the difference between Constant Window, Variable Window,Main Window

hello all
what is the difference between 1) Constant Window
2) Variable Window
3) Main Window in SAP SCRIPT

Hi,
Window Types
When defining a form window, you must select a window type for the window.
You can choose between three types:
Constant Windows (CONST)
Variable Windows (VAR)
Main Windows (MAIN)
Constant Windows (CONST)
Starting with Release 4.0, the system internally processes windows of type CONST similar to windows of type VAR.
Therefore, if you create a new window, always use type VAR.
Variable Windows (VAR)
The contents of variable windows is processed again for each page, on which the window appears.
The system outputs only as much text as fits into the window. Text exceeding the window size is truncated;
the system does not trigger a page break. Unlike constant windows, the page windows declared as variable windows may have different sizes on different form pages.
As far as the processing of the window contents is concerned, the system currently treats constant and variable windows alike.
The only difference is that constant windows have the same size throughout the form.
Main Windows (MAIN)
Each form must have one window of type MAIN. Such a window is called the main window of the form.
For SAPscript forms, the main window has a central meaning:
It controls the page break.
It contains the text body that may cover several pages.
It allows to fix text elements at the upper and lower margins of the allocated page window (for example, for column headings).
As soon as a window of type MAIN is full, SAPscript automatically triggers a page break and continues to
output the remaining text in the main window of the subsequent page. Page windows of type MAIN have the same width throughout the form.
The SAPscript composer thus avoids reformatting of the text after each page break.
If a page does not have a main window, the system implicitly processes all other windows of the page and continues with the subsequent page.
This page must not call itself as subsequent page (recursive call), since this would produce an endless loop.
In such a case, SAPscript terminates the output after three subsequent pages.
For printing header lines or totals, the different output areas of the main window are of special importance.

What are the differences between attributes and variables?

I am trying to develop a firmer understanding of the difference between attributes and variables. I understand attributes are lexically scoped to a class and variables are lexically scoped to the enclosing block. The lifetime of an attribute is linked to a class' instance. What is the lifetime of a variable? What is the lifetime of variables declared in a script file's top-level?

It depend on whether the script is running in standalone mode or been called by others (library mode).
If running as standalone, the variable of the script in the top level exists until the the script exit. If run as library mode, the variable in the top level of the script will never get to execute. Only the function and class available for call.
Try calling another script with top level variable (place print statement to verify), you realize in library mode, it will never been called. That's why the main method as in Java is never needed because of this reason.

What is the scope of implicit loop variables?

Hi,
I'm facing some strange error from the ABSL editor (syntax checker).
In ABSL the loop variables are implicit and don't have to be declared in the head section of the script.
My question now is simple: How is the scope/visibility of such loop variables specified ?
There's a complete code snippet below.
In line no.9, there's the first time use of implicit loop variable 'task_inst'.
Because of type inference, it will be typed as MasterDataWanneBe/Tasks (which is my own BO type).
In line no.20, I want to use the same variable name in a different loop, outside the parenthesis/scope of the first first use.
Now the ABSL syntax checker complains about incompatible types (see code snippet)
Thus the type inference should result in the, (lets say 'local') type Project/Task, which is the one I was querying for.
To me it looks like, that loop variables implicitly get a global scope (hopefully bound to this ABSL file only).
I would like to see the scope/visibility of loop variables restricted to the parenthesis.
In other words only inside the loop.
Hint
I heard (from little sparrows), that local variable scoping is not possible because of underlying
generated ABAP code. If so, than it would be helpful to print warnings, in case of types are compatible
but used in different scopes. Think about the unintended side effects.
import ABSL;
import AP.ProjectManagement.Global;
var query_tasks;
var query_tasks_param;
var query_tasks_result;
foreach (empl_inst in this.Employees) {
     foreach (task_inst in empl_inst.Tasks) {
         //   ^^^^^^^^^ first time use
          task_inst.Delete();
// ===========================================================================
query_tasks = Project.Task.QueryByResponsibleEmployee;
query_tasks_param = query_tasks.CreateSelectionParams();
query_tasks_result = query_tasks.Execute(query_tasks_param);
foreach (task_inst in query_tasks_result) {
      // ^^^^^^^^^ Error: 4
      // The foreach loop variable is already inferred to an incompatible type:
      // Node(MasterDataWanneBe/Tasks). Expected Node(Project/Task)

Yes, variable declarations in ByD Scripting Language indeed have (snippet) global visibility. In the FP 3.0 release the variables can be declared anywhere in the snippet (not only in the beginning, as with FP 2.6), however still not within code blocks, i.e. within curly braces ({}). Therefore variable name shadowing is still not supported and because of the global visibility of variables they cannot be reused for a different type, later in the same snippet. This is because of the statically typed nature of ByD Script, despite the type inference convenience.
Kind regards,

What is the file name crdb_jdbc.dll(Windows) equivalent to Linux?

Hi,
What is the equivalent file name of crdb_jdbc.dll for linux connection info for database?

It's crdb_jdbc.dll.
Within the connection info, the name of the DLL specifies the connectivity driver type, that just so happens to correspond to the specific DLL file for that driver for Crystal Reports C++ engine on Windows. For other deployments and engines (such as CRJ), it gets the right one if you specify crdb_jdbc.dll.

What is the blue thing in shared variable?

I'm going thorough a code which has huge set of shared variables and in some nodes I find a blue colored mark/thing just bottom left to the globe as shown below. What does this indicates?
Thanks,
Ajay
Solved!
Go to Solution.

I found the answers from my team member. The blue mark actually indicates a dot and a slash ".\" which means Target Relative Shared Variable. If the Shared Variable is Absolute, then this indication will not be shown. To know more about the difference between Absolute and Target-Relative shared variable, check it out here. A Shared variable node can be swtiched between Absolute and Relative using

Does the Aironet 3600 can be used in France (5ghz) ? What is the PSU voltage ? Hwic module equivalent exist ?

Hi,
Does the power supply from aironet 3600 series, AIR-CAP3602I-A-K9 is compliant with french voltage ?
Is it 110-220 input ? How to have a standart french plug or adapter if i bought this item in US ?
Does this hardware can be used in France regarding authorized wireless frequency 2.4 and 5 GHz (802.11a/b/g/n/ac) ?
Do you know if it exist any kind of HWIC module with same wireless performance that it can be used with G2 ISR Router (19xx/29xx/39xx) or previous generation ISR (18xx/2xx/38xx) ?
Best Regards.

Does the power supply from aironet 3600 series, AIR-CAP3602I-A-K9 is compliant with french
If you enable this AP, you are likely breaking French law. This AP is configured to be use with "-A" Regulatory Domain.
France should be using "-E".
Power supply issue ... 3600 will work with 15.4w PoE as long as you don't add modules. If you do, you need 20.0w PoE.
You have three choices: PoE switch, Power Injector 3 or Power Brick.
Edit: Just re-read your post about "802.11a/b/g/n/ac" so this confirms you need 20.0 PoE. So the same choices are still applicable: PoE+ switch, Power Injector 3 or Power Brick.

What is the difference between Instance variable and Global variable?

Hi folks,
Could you please explain me, "what is the difference between Instance variable and Global variable?"
Are they really same or not?
--Subbu

Hi flounder,
I too know that there is no such a term GLOBAL in java.
generally people use to say a variable which is accessible throught out the class or file has global access
and that will be called as a global variable...
my point is very much similar to what Looce said.
In simple that is not a technical term, but just a causual term.
In technically my question is, "What is the difference between a instance variable and public variable?".
Hi looce,
Thanks for the reply. even thats what my understanding too....in order to confirm that i raised this question..
Your reply has given a clear answer...... thanks again.

What is the proper and best way to destroy a java.util.List or Array for GC

Hi,
If I have a java.util.List of objects lets say:
List<File> files = new ArrayList();The List contains 1000 file objects. When my class finishes, is it enough to do
files = null;to make GC able to release it from memory?
Cause it seems like I can't do the following:
for(int i = 0; i < extracted_files.size(); i++){
extracted_files.get(i) = null;
}Or should I use this one:
files.clear()What is the proper and best way to do this in order to avoid memory leaks? How about normal Arrays like File[]?

Thanks for the info!
But what if the List is a class variable running in a Web Service for like months without terminating?You mean if the List variable is a member variable of a long-lived object? Then presumably the list needs to live as long as the object does. In the unlikely scenario that the object needs to live on but its list member variable does not, then yes, setting the member to null will be needed to make the list eligible for GC. But I highly doubt this is your situation, and if it is, you probably have a design flaw.
And if the list is referenced only by a local variable, then, as I already said, when the method ends, the variable goes out of scope, and the List is eligible for GC.
Now, a slightly different situation is when the List needs to live a long time, and at some point during its life, you're done using some object that it refers to. In that situation, simply remove the element from the list (or set the element to null if it's an array rather than a list), and then if it's not referenced anywhere else, it can be GCed.
How about Arrays like File[]? Do I need to iterate through the array and null all the objects or is it enough to just null the Array?YOU. DON'T. NEED. TO. HELP. GC. You don't need to set the elements to null, and you most likely don't even need to set the array variable to null.
Also note that only references can be null, not objects.

What is the main difference between LOCAL VARIABLE, REFERENCE, PROPERTY NODE and INVOC. NODE?
Can u show this with an example in a VI using all these?
Basic overview. Someone can go into more depth if they want.
Local Variable - Correlates to some location in memory that holds information. Based on the data type, it looks at that location and interprets the 1's and 0's as either a double, integer, string, structure(cluster), etc.
Reference - ill leave the details of this to someone else I can't give a decent explanation.
Property node- sets different "properties" of a control/indicator etc. One of the properties is value so that works similar to a local variable. However, you can set much more than that. For example, with controls you can set the property of visible, not visible, color, etc etc.
Invoke node - invokes some "method." i.e. calls some function to act on something
These may not be the best explanations, or even 100% correct. But it should get you started. I'm sure someone else will build on this.

What is the difference between variable and Define

WHAT IS THE DIFFERENCE BETWEEN
these different declarations when it is done using the keyword "variable" and "define"
and both of these are done OUTSIDE "DECLARE"
VARIABLE g_monthly_sal NUMBER
DEFINE p_annual_sal =5000
-- I understand that p_annual_sal will be taken as a CHAR.
-- ALSO IF DEFINE variable acts as macro variable, SO is it necessary to give it some value whenever we define it.
if not what value would be substituted for it?
OR does that mean whenever we want to specify data type for a bind varible we should use VARIABLE and
when we do not want to specify type we use DEFINE?
THANK YOU

Both are SQL*plus commands. In a real programming environment you will not use such constructs (except a few rare scripting cases).
The difference is how the construct is later used. DEFINE is more like a copy&paste string. Whereever the name of this substitution variable is found it will be pasted into the sql*plus session.
VARIABLE creates a real variable. You can change the value and if follwos the usual principles of variables (including binding).
Example can be found the docs:
from the docs
Where and How to Use Substitution Variables
You can use substitution variables anywhere in SQL and SQL*Plus commands, except as the first word entered. When SQL*Plus encounters an undefined substitution variable in a command, SQL*Plus prompts you for the value.
You can enter any string at the prompt, even one containing blanks and punctuation. If the SQL command containing the reference should have quote marks around the variable and you do not include them there, the user must include the quotes when prompted.
SQL*Plus reads your response from the keyboard, even if you have redirected terminal input or output to a file. If a terminal is not available (if, for example, you run the script in batch mode), SQL*Plus uses the redirected file.
After you enter a value at the prompt, SQL*Plus lists the line containing the substitution variable twice: once before substituting the value you enter and once after substitution. You can suppress this listing by setting the SET command variable VERIFY to OFF.
Using Bind Variables
Bind variables are variables you create in SQL*Plus and then reference in PL/SQL or SQL. If you create a bind variable in SQL*Plus, you can use the variable as you would a declared variable in your PL/SQL subprogram and then access the variable from SQL*Plus. You can use bind variables for such things as storing return codes or debugging your PL/SQL subprograms.
Because bind variables are recognized by SQL*Plus, you can display their values in SQL*Plus or reference them in PL/SQL subprograms that you run in SQL*Plus.
Creating Bind Variables
You create bind variables in SQL*Plus with the VARIABLE command. For example
VARIABLE ret_val NUMBER
This command creates a bind variable named ret_val with a datatype of NUMBER. See the VARIABLE command for more information. (To list all bind variables created in a session, type VARIABLE without any arguments.)
Referencing Bind Variables
You reference bind variables in PL/SQL by typing a colon (:) followed immediately by the name of the variable. For example
:ret_val := 1;
To change this bind variable in SQL*Plus, you must enter a PL/SQL block. For example:
BEGIN
:ret_val:=4;
END;

What is the correct syntax for using a variable in an ad hoc query?

Hi all
I am an occasional DB user and at the moment need to update about 1000+ records so that a certain column gets a unique value.
So I thought that I would use a variable for this.
I then built this kind of SQL statement for just a small subset of the records:
variable recNumber number;
exec :recNumber := 1;
UPDATE TABLE_TO_BE_UPD
SET COL_TO_BE_UPD = COL_TO_BE_UPD + recNumber
WHERE COL_TO_BE_UPD IN ('VAL_A','VAL_B');
I get the invalid SQL statement error when attempting to execute above (besides the prompt that asks for a value which I would like to omit).
Anyway I also tried this one:
CREATE SEQUENCE seqCounter;
UPDATE TABLE_TO_BE_UPD
SET COL_TO_BE_UPD = COL_TO_BE_UPD + seqCounter.NEXTVAL
WHERE COL_TO_BE_UPD IN ('VAL_A','VAL_B');
From this one I got the error ORA-01722: invalid number...I am guessing this comes because seqCounter is of type number and the COL_TO_BE_UPD is of type character...(?)
So what I would like to ask is what is the correct way to define and use a counter type of variable to append a number at the end of a character string?
Also another question that I would like to ask is that are variables that are used in ad hoc queries also called 'bind variables'?
Thanks muchly

If you want to append a unique number to a column then this would do it:
UPDATE TABLE_TO_BE_UPD
SET COL_TO_BE_UPD = COL_TO_BE_UPD ||to_char(rownum)
WHERE COL_TO_BE_UPD IN ('VAL_A','VAL_B');

What are the best practices to use GLOBAL Variables

Hi,
Please guide how Global Variables can be declared and how they can be initialized.
Further please guide what are the impacts of Global Variables(if any) on the memory of CLIENT or SERVER, if they are not initialized or freed up after usage.
Thanks.

I don't know how often I searched for bugs caused by typos in the names of global variables. Plus the fact that they are only of datatype VARCHAR2. If you are using share_library_data you could also use Package globals in a forms library to share data between called and calling forms. Or you could use a database package...
