Doubt with Collections.singleton(Collection)

Hi,
can anyone help me in understanding the difference between.
Collection.removeAll(Collection)and
Collection.removeAll(Collections.singleton(Collection)).
Thanks in advance....
regards,

The difference is merely that the second one is pointless.

How can I copy a Font Book library with "Collections" to my 2nd laptop?

How can I copy a Font Book library with "Collections" to my 2nd laptop?
I have a number of fonts (approx. 500) on my work laptop which are sorted to different Collections. I'd like to have a copy of the Font Book library with Collections on the laptop I use at home to work. I'd think there was a more straight forward way to do it, but I haven't found any posts regarding the matter so any help would be appreciated.
Thanks

To anyone who is reading this based on needing to copy their Font Book to another machine as I do, there is a way to make a copy of the fonts in Font Book by going to file/export fonts. Keep in mind that you will need to have all the fonts selected (command A) in your "All Fonts" list for them to be exported. You will then have a new folder saved to where ever you chose, with all your Font Book fonts in it.

EJB 3.0: How to merge detached entity with collection

Hello,
suppose you have 2 database tables: PARENT and CHILD with one-to-many association. In a session bean you load the parent entity together with collection of children and send it all to client. Client might change parent or child data, add/remove children.
Now back in a session bean you want to update database, so you call:
entityManager.merge(detached_parent_entity);Problem is, that removed child objects from entity bean collection are not deleted from database. Bacause I am currently using Hibernate, I could follow the FAQ (http://www.hibernate.org/116.html#A17) and add delete-orphan cascade, but I don't want to be tight to Hibernate nor other frameworks.
Is there any sexy solution?
Thanks for replies!

I'm afarid not - a generic feature that will allow to
delete orphan children didn't make it into the final
spec.
regards,
-marinaDo you happen to have any links to public discussions about this feature with regard to the development of the spec? This is a very nice feature in Hibernate and it's absence in EJB 3.0 is rather disappointing.
Thanks.

Problems Creating Mappings with Collections with tools or workbench

Hi -
I am a new kodo user for my company. And am having a few problems in genereal with mapping objects with collections
in them.
I followed the tutorial on how to use the kodo workbench
using the Passenger example. Build the java code and then
tried to creat a new set of metadata. After going through
this process I expected to see TWO tables. Something like
'PAssenger' and something like 'Luggage' where luggage
would be joined to passenger. However what I am getting
is ONE table passenger with a BLOB field 'Luggage'. This
has been a contant problem with me with any composite
java class containing collection. Obviously I am configuring something wrong. Any help would be great.
Thanks

Problems with collective search help

Hello SDNers,
I was working with collective search help.
Ex : zc_srch1 (Collective)
In the 'Include search help' i have included 2 search elementary search
help
Ex : zsrc1 and zsrc2 (both elementary)
I have also assigned the parameter assignment for each included search help.
I have also mentioned the search help parameter under definition tab
Ex field form zsrch1 and field1 from zsrch2
and also checked the import and export checkboxes.
Now i have used the search help in the abap program
ex: tmp type field1 matchcode object zc_srch1.
Now when i execute the program the collective search help is getting populated. when i try to choose a value it is not getting selected to the parameter box.

Working with collections in powershell

Hi,
I'm struggeling with collections in Powershell in general.
I have a variable of type SPWebCollection created and want to add
1) a single SPWeb - Object
2) another collection of SPWeb - Objects
Can someone tell me please why the following doesn't work:
[Microsoft.Sharepoint.SPWebCollection]$allWebs += Get-SPWeb $URL1
or this
[Microsoft.Sharepoint.SPWebCollection]$allWebs += $site.AllWebs | Where-Object {$_.Url -like $URL2}
Finally I want to empty the $allWebs collection i.e. remove all objects. How do I do that?
I appreciate any feedback
Thank you

Hi,
According to your description, you might want to gather all the SPWeb object into a collection object in order to delete all of them finally.
As we can see, there is no such method in
SPWebCollection object can meet you requirement, as a workaround, we can push all the SPWeb objects into an array, then operate
these SPWeb objects in this array would do the trick.
Here is a link about how to create a generic collection for a list of objects:

How to execute a procedure with collection passed as parameter?

i have created the collection:
CREATE TYPE typ_Project AS OBJECT( project_no NUMBER(2), title VARCHAR2(35), cost NUMBER(7,2))
CREATE TYPE typ_ProjectList AS VARRAY (50) OF typ_Project
and a procedure:
CREATE OR REPLACE PROCEDURE add_project (
p_deptno IN NUMBER,
p_new_project IN typ_Project,
p_position IN NUMBER )
IS
v_my_projects typ_ProjectList;
BEGIN
SELECT projects INTO v_my_projects FROM department
WHERE dept_id = p_deptno FOR UPDATE OF projects;
v_my_projects.EXTEND;
FOR i IN REVERSE p_position..v_my_projects.LAST - 1 LOOP
v_my_projects(i + 1) := v_my_projects(i);
END LOOP;
v_my_projects(p_position) := p_new_project; -- add new
UPDATE department SET projects = v_my_projects
WHERE dept_id = p_deptno;
END add_project;
Now please explain how to call this procedure with collection passed as parameter . . .

For example:
BEGIN
    add_project(
                10, -- department number
                typ_Project(
                            99, -- project number
                            'New Project', -- project title
                            99999.99 -- project cost
                           ), -- new project
                5 -- project position

Hi i have some problem with collect statement.

hi when i am using collect statement and whn ever any field is modified it is getting doubled and showing doubled value. may i knoe what would be problem.

Hai Kumar
Go through the following Collect Syntax
COLLECT
Basic form
COLLECT [wa INTO] itab.
Addition
... SORTED BY f
Effect
COLLECT is used to create unique or compressed datsets. The key fields are the default key fields of the internal table itab .
If you use only COLLECT to fill an internal table, COLLECT makes sure that the internal table does not contain two entries with the same default key fields.
If, besides its default key fields, the internal table contains number fields (see also ABAP/4 number types ), the contents of these number fields are added together if the internal table already contains an entry with the same key fields.
If the default key of an internal table processed with COLLECT is blank, all the values are added up in the first table line.
If you specify wa INTO , the entry to be processed is taken from the explicitly specified work area wa . If not, it comes from the header line of the internal table itab .
After COLLECT , the system field SY-TABIX contains the index of the - existing or new - table entry with default key fields which match those of the entry to be processed.
Notes
COLLECT can create unique or compressed datasets and should be used precisely for this purpose. If uniqueness or compression are unimportant, or two values with identical default key field values could not possibly occur in your particular task, you should use APPEND instead. However, for a unique or compressed dataset which is also efficient, COLLECT is the statement to use.
If you process a table with COLLECT , you should also use COLLECT to fill it. Only by doing this can you guarantee that
the internal table will actually be unique or compressed, as described above and
COLLECT will run very efficiently.
If you use COLLECT with an explicitly specified work area, it must be compatible with the line type of the internal table.
Example
Compressed sales figures for each company
DATA: BEGIN OF COMPANIES OCCURS 10,
        NAME(20),
        SALES TYPE I,
      END   OF COMPANIES.
COMPANIES-NAME = 'Duck'. COMPANIES-SALES = 10.
COLLECT COMPANIES.
COMPANIES-NAME = 'Tiger'. COMPANIES-SALES = 20.
COLLECT COMPANIES.
COMPANIES-NAME = 'Duck'. COMPANIES-SALES = 30.
COLLECT COMPANIES.
The table COMPANIES now has the following appearance:
NAME SALES
Duck 40
Tiger 20
Addition
... SORTED BY f
Effect
COLLECT ... SORTED BY f is obsolete and should no longer be used. Use APPEND ... SORTED BY f which has the same meaning.
Note
Performance
The cost of a COLLECT in terms of performance increases with the width of the default key needed in the search for table entries and the number of numeric fields with values which have to be added up, if an entry is found in the internal table to match the default key fields.
If no such entry is found, the cost is reduced to that required to append a new entry to the end of the table.
A COLLECT statement used on a table which is 100 bytes wide and has a key which is 60 bytes wide and seven numeric fields is about approx. 50 msn (standardized microseconds).
Note
Runtime errors
COLLECT_OVERFLOW : Overflow in integer field when calculating totals.
COLLECT_OVERFLOW_TYPE_P : Overflow in type P field when calculating totals.

Doubt with a Insert query!

hi friends i have a doubt with a query in sql here is the following code.
INSERT INTO
                     (SELECT employee_id, last_name,
                                  email, hire_date, job_id, salary,
                                  department_id
                       FROM employees
                      WHERE department_id = 50)
           VALUES (99999, 'Taylor', 'DTAYLOR',
                        TO_DATE('07-JUN-99', 'DD-MON-RR'),
                         'ST_CLERK', 5000, 50);The same insert statement can be achieved with
INSERT INTO EMPLOYEES (employee_id, last_name,
                                  email, hire_date, job_id, salary,
                                  department_id)
                    VALUES (99999, 'Taylor', 'DTAYLOR',
                        TO_DATE('07-JUN-99', 'DD-MON-RR'),
                         'ST_CLERK', 5000, 50);What advantage does the first query have over the second one.
Thanks in advance to everyone.
Regards,
Manoj

Those two statements are identical.
However this one would be different:
INSERT INTO
(SELECT employee_id, last_name,
        email, hire_date, job_id, salary,
        department_id
   FROM employees
   WHERE department_id = 50
   with check option )
VALUES (99999, 'Taylor', 'DTAYLOR', TO_DATE('07-JUN-99', 'DD-MON-RR'), 'ST_CLERK', 5000, 50);The "WITH CHECK OPTION" would guarantee that only employees for department 50 are inserted.

Doubts with working in BI

Dear Experts,
I am sure SAP follows the same concepts in BI as just recently i have worked in JasperSoft Talend Open studio.
But i have some doubts with BI.
I created a RFC in ABAP. Used that RFC to bring data for a single day as parameter on to ingres database table .The ingres table is of same schema as of structure output.Finally i find that ingres table is populated after running relevant job.
Now i thought to work twoards report and that worked as well.But still i have doubts.
As i am new to BI ,i dont know what advantage i got by doing this breathless activity.
(1) I would have simply used sap itself to generate report.What was the need to bring to mysql.Load to my server remain same because definitely RFC will be executed nowhere but on server itself.
(2)If daily i have to run the same job ,obviously i could have done same with sap.Same amount of data will be retrieved with
same overheads.
As i said that i am new to BI.Plz explain me about power of BI and what i am missing to conceptualize ?

Aditya,
You can definitely use SAP R/3 to generate these issues - the only issues are :
SAP R/3 is an OLTP system
by OLTP system the system is optimized / tuned to be able to do inserts and updates to tables but then the default indices are not tuned for reads ... this might cause report performance issues...
SAPR/3 is not supposed to hold more than 2 years of data at best ( unless your system is small enough ) whereas a BI system can hold and should hold much more information.
Getting the master data descriptions for the data you are reporting upon and that too across languages can be a challenge - whereas it can be better handled in a BI system...
As for extracting large volumes of data you should use the Service API that comes with SAP Bi for better extraction performance ...
some points why you need a BI system.....

Did this help you ??
Not sure if it's related as here the issue is with clustered/non clustred and versioning!! the application which the bug talks about.

Doubt with Implicit Enhacement in SAP ABAP

Dear.
I have the following doubt with the Implicit Enhacement in SAP ABAP created by me in several applications standard-
If I Create an Implicit Enhacement in SAP ABAP for a function module or program standard , when the team basis is doing an upgrade the code abap created in the Implicit Enhacement not is deleted?
I have created several Implicit Enhacement for Applications WD ABAP and FM, but I have this doubt.
http://wiki.sdn.sap.com/wiki/display/ABAP/HowToDoImplicitEnhancement
Thanks a lot in advance.
Carmen G.

Hi,
you code will be retain after upgrade. If you have done implicit enhancements doesnt mean your code would get deleted after upgrades.
In some cases you might have to activate your enhancments using SPAU.
Thanks
