How to type case double in Oracle?
there is no such thing TO_DOUBLE('A_NUMBER') in oracle
so how can i convert a number to double???
I know number it self can treat as double...
What are you trying to accomplish?
Are you perhaps trying to convert to a binary_double?

RMPS, RM, CM: How can I attach the element type Case Locator to a model?
EN
It is necessary to provide the Search of a case from the Record (not from the Electronic desk (scaseps)). So I attached the element type Case Locator to my record model. But there are some problems. I see only the place holder of the element and only if the record is opened in the change mode. I tried to attach it as an instance, but the element has no POID. If You had the same problem and know, how to do it, please help me. Thanks.

Wie kann ich den Element Type Case Locator zu einer case/record Model anknüpfen?
Es ist notwendig die Suche eines Cases aus einer Record zu machen (nicht aus dem Arbeitstisch ->Transaktion scaseps). Ich wollte den Element type Case Locator zur Record model anknüpfen. Aber da gibt es Schwierigkeiten: der Element ist lehr, d.h. man kann ihn ausnützen und sehen nur wenn der Case für Veränderung geöffnet ist und ich kann ihn nicht wie eine Instance anknüpfen (das ist eigentlich verständlich, weil der Elenemt keinen POID hat). Falls Sie so was schon gemacht haben, raten Sie mir bitte, wie es richtig gemacht wird. Danke.

RM, CM, RMPS: Как присоединить Case Locator к модели?
В регистре есть сервис провайдер Case locator. Возникла необходимость реализовать поиск случая, из записи, а не из рабоченго стола. Решила к модели записи присоединить вид элемента Case Locatоr, но возникли нюансы: Вид элемента присваевается как пустой (place holder), виден и работает только при отрытии записи в режиме "изменение". Присоединить его как инстанцию не получилось (оно и понятно, отсутствует POID). Коллеги, если вы работали с этим видом элемента, сталкивались с подобыми задачами и нашли из них выход - подскажите пожалуйста.

How to display an double type variable's value with two decimals?
for exmple, what I do is:
double a = 1.5;
system.out.println(a);
I see 1.5 in the screen, however, I wanna display 1.50. how to do that?
I know how to round an double value, say, 1.555 to 1.56, but I can't find how to display a double value from one decimal to two decimal, any help will be very appreciate!for exmple, what I do is:
double a = 1.5;
system.out.println(a);
I see 1.5 in the screen, however, I wanna display
1.50. how to do that?
you could convert the double to a string and then append a zero to the end
String str = Double.toString(a);
str += "0";
System.out.println(a); -
Does any one know how to wrap a view in Oracle, I know it is not possible, yet. Are there any third party software to wrap the logic in the view.
Thanks,
SanjayYour best bet is to write a view that queries the source tables and contains any necessary business logic
CREATE VIEW VBASE AS SELECT A.COLUMN_A FROM TABLE_1 A, TABLE_2 B, TABLE_3 C WHERE A.ID = B.ID AND B.ID = C.ID;
create a view for exposure to the user that queries the base view.
CREATE VIEW VSECURE AS SELECT COLUMN_B FROM VBASE;
and grant privileges to VSECURE.
GRANT SELECT ON VSECURE TO SECURE_USER;
This will allow the user to see, query, and describe VSECURE without seeing the definition for VBASE.
The advantage of the this approach is that the query engine can still push predicates down into the base view to optimize the performance or the query where as this is limited with the pipeline function and can become a tuning headache.
eg.

How can I code this in Oracle Forms?
I have a master-detail form. In the detail block, I have several records. Here is my name table.
ID Name_Type Name
1 old Mike
2 Current John
3 old Peter
4 old Andrew
I would like to create a button trigger which shall perform the following:
1) insert a record into database with a copy of current value. In the above case it will insert create a record for John as name_type = 'OLD'. So we have total of 5 records. Commit the transaction.
2) Scroll through my detail records (5) and go to one specific record and erase the values from it. In the above case, it should find John's record with name_type = 'Current' and erase John from it.
How can I accomplish this in Oracle forms using a button-pressed trigger?Hi,
Simple, using current values you can create new id , 'old' and name so oracle will create record, now refresh block, next using next_record in loop you can find record,erase one and refresh block.

Need help in writing test cases while upgradin oracle from 10g to 11g
hi all
I want to write test cases for ugrading oracle 10g to 11g i have some idea but want your input.and at the same time some people taking upgrade testing as to ensure that everything works after the upgrade - stremas, jobs, procedures.but i think as 11g is backward compatible all the things should work properly.If not then how can we write a test cases for that,your help is most welcome.
Thanks in advanceHi;
Please see below notes which could give you some idea to create your test case. By the way if your components are certified wiht 11g so there should be any bad issue for your upgrade

In the libary of iPhoto I do have double pictures only in the year 2006. Can someone please tell me how to remove the double pictures. I did rebuilt the libary but that solution did not help me any further.
I think the warning is very clear.
What warning? Where do you say that this plan you suggest will lose at least some, and possibly a whole lot of metadata, plus the original files of edited photos. This is significant dataloss. And you should warn people that this is the case.
While your metadata and originals may not be important to you, that is not necessarily the case for other users.
Fourthly, and last, cleaning the iPhoto library should be done at least once per year
This is nonsense. The iPhoto Library has no need of "cleaning" and certainly not in any way that trashes a whole lot of data.
I'm very impressed that you assess the application based on the sound of the name. It's not a common way to review applications, but I'm sure it has some merit.
FWIW it has been recommended on this - and other - sites for many years and has proven safe and effective.

Case Statement in Oracle Query.
Hello Oracle Gurus,
I need suggestion on whether I should use Case statement in Oracle queries.
I have a sql statement which inserts the data by selecting data from other table. While selecting the data I have put a logic in the select statement for one column which is something like this and there are some more similar statements in the same query.
CASE
WHEN (b.ACCOUNT = 'FIN' or b.ACCOUNT ='FIN ACC' or b.ACCOUNT like '%Global Eq%' or b.ACCOUNT like '%Flexible Bond%')
THEN
'MTM'
WHEN (substr(a.CTC,-3)='MTM')
THEN
'MTM'
WHEN (substr(a.CTC,-3)='AFS' or substr(a.CTC,-3)='HTM' OR substr(a.CTC,-3)='ACC' OR substr(a.CTC,-3)='HFI' )
THEN
'ACC'
ELSE
'OTH'
END,
I wanted to get an suggestion about how much performance issue can I have due to this in my insert statement.
Let me know if you need any other information.All comments are really appreciated.Hi,
It's depends on the joins how you have performed with source table, stats and existing of indexes. If the volume of data is high - in case of any performance issue - why can't you perform the required things of logical conditions of data and popualte in one cluster so - that you can fetch out the chunks of required information with better way and in support with indexes.
Let us know the ful query your working on

How To Connect Microsoft Excel To Oracle DB
Hi,
My team recently took over a process from another company. The other company had a macro written which connects to oracle DB and gets the o/p result in Excel.
If i try to use this macro based sheet, I get error.
Though i pass the right password it through's error.
Error is "ORA-06413: Connection not open"
Where as if i try the same user name and password in toad it works.
I see that in my system i don't have "ORACLE Provider for OLE DB" and i also don't have "Oracle DB Driver".

How to verify stored procedures in Oracle 10g.
I would like to locate default stored procedure in Oracle 10g database.
And Suggest which stored procedure can be converted in to JAVA code ??If the Java part of the question refers to looking for potential to speed up your stored procedures:
You should consider native compilation which transfers your code to shared libraries which are bound to the DB kernel.
In this case however consider, that this does not make any sense/improvement for pure data access statements but only for procedures consisting of complex algorithmic processing.
