User defined function join VS - Performance...
Hi allall connecting mulitple table and get values... which one is the best?
Join or user-defined function...
row function
--------------------------
Select b.SID, get_salary (empid) from emp;
Note: get_salary function will return the salary of the pay tables.
Using joins
--------------
Select b.SID, b.salary from emp, a, b of salary
where a.empid = b.empid;
What is the best performancewise?
also if you give any related document also very well.
Thanks in advance.

I just noticed that these files appear to be copyrighted. My first question is do you have author permissions to post them in a public forum? If this isn't the case, then you can remove them. That being said, I have reviewed the code and it seems easy enough to work around your problems (provided that you have the copyright permissions). How to bypass the problems is to replace the fields of the struct with variables. There is of course allows you to change some definitions of functions for input and output the necessary variables which I think was the best 5 variables. You will also need to redo the code that uses a table of error checking cell. In total, I estimated about 30 minutes of work. I would have given you work around these files had not been protected by copyright. So, unfortunately, you will need to implement the work around you.

How to create a user-defined function?
is there a substitute for the exe instsrv and srvany in Vista?
I don't know what means your post, so here's how to create a user-defined function:
1) click Start
(2) select "Control Panel".
(3) select "system and maintenance".
4) click on "Administrative Tools".
5) click on "Task Scheduler."
(6) click on "create task" (right in the list pane under) "Actions") "
"(7) opened in the general tab it will choose if it only works when the account that is used to implement is connected, or ' if that user is logged in or not" (leave the box ' do not store the... "empty password)
(8) always in the general tab, check the box 'run with highest privileges '. (This will ensure that no program can block)
(9) type a name for the task (in the general tab)
(10) to set the job to run an awhile, use the "triggers" tab, if you want to set a task runs after xx min. temps_inactivite, choose the 'conditions' tab, then choose the desired time.
(12) click on the 'actions' tab click on 'new '. in the program/script line, search for and select the program you want to run, and then click Open.
13) click OK in the window "create a task".
14) click OK again and you are done.

User-defined function removes the expression hooks
Trying to convert this column in a user function expression, however when I apply the function to the user hooks literally disappear.
1 REGEXP_REPLACE (SRC_IO_PHONES_A.PHONE, ' ({: digit:{3})\.(:digit:{3})\.(:digit:{4})' 1 (\1)-\2-\3'),)
2 REGEXP_REPLACE (SRC_IO_PHONES_A.PHONE, ' ([[: digit:]] {3})------.) () [[: digit:]] {3}). ([[: digit:]] {4})' 1 (\1)-\2-\3')
These lines come from the same mapping. One implements the user-defined function and the second line is with I plug the code into the target Expression field.
Any thoughts on why this is?
Thank you
So I thought to it thanks to a post of @oraclebase. Another friend of mine has indicated that user in ODI functions develops a sort of pseudo-code and it is not really passing commands to the database. Anyway, my research turned to substitute for the construction of all [: digit:]. This resulted in me find the above post where \d = [0-9]. By replacing all the scoring by \d hooks, the function worked.

None of the answers was * exactly * correct, but they gave me enough information to solve the problem.
To implement what I have to code the functions a bit differently.
- BPEL functions are all the IXpathFunction extension classes.
- Mapper functions are not.
- BPEL functions are each separate classes.
- A single class with a method for each desired function mapper functions.
- BPEL classes outcrop in the config file ext-bpel-xpath-functions-config. XML
- The Mapper class is exposed in the config file ext-Mapper-xpath-functions - config.xml
A BPEL class looks like:
public class editCaseNumber implements IXPathFunction { public Object call(IXPathContext context, List args) throws XPathFunctionException { return docOut; } }
A class to map looks like:
public class mapperFunctions { public static String replaceString(String sIn,String sMat,String sRep,String mode){ return finalString; } public static XMLDocumentFragment compressFile(String indoc){ return docOut; } }
(I deleted the code of these to avoid confusion.)
My ext-Mapper-xpath-functions file - config.xml looks like:
soa-xpath-functions xmlns="http://xmlns.oracle.com/soa/config/xpath" xmlns:map="http://www.oracle.com/XSL/Transform/java/com.f17.customfunction.mapperFunctions" version="11.1.1" resourceBundle="oracle.tip.tools.ide.common.resource.IDEMessageBundle" >

any user defined function in the rule set by the user
Hello
I wonder if I can use a function defined by the user in a rule set by the user in oracle sem... I've seen examples of user defined function the used in sparql query filter clause in this guide to dev... However, I don't know if I can define a function in oracle database SEM. and use it in the body rule or the head. For example, I want to define a function of the length that allow to calculate the difference between two dates. So, I want to set a rule as follows: event1: d1 and event1 has_start_date: has_end_date d2 and duration (24, d1, d2) then event1:date_satisfiable 'yes '. Oracle supports this type of rule? Thank you very much.

}
While (err > 0.001 | err <-0,001 & & I < = 100);

Is there something to do with the double data type, int, double? Essbase spend 'int '?
Help, please! Thank you very much!!
Published by: user9132709 on March 2, 2010 12:47I just tried and it works.
I also added
System.out.Print (MBound);
just before the return (MBound);
in the Java class
I created a calc script against Sample.Basic

('Sales'
'Sales' = @Amort (0.06, 360, 10000000);

I run essbase in the foreground, so I see the exit of System.out.print (Mbound);
Validated the script "59955.05251799688" was written in the output window, so the Java class works.
I also ran the calc script and the value was written in 'Sales' (the block already existed for the POV before anyone says that my script would not work)I registered the CDF of Java with.
create or replace function '@AMORT' as

Help! User-defined function problem.
Need help on using custom function defined in Essbase. Thanks in advance!
I have not found a function of depreciation in Essbase, so thought I might create one in Java and save it as a user defined function. However, I can't get this to work.
Here's what I did:
1. I created a java class called depreciation.
public class {depreciation
public double Adeath (double r, int period, double LoanBalance) {}
Double LBound = LoanBalance/period;
Double UBound = LoanBalance;
Double MBound =(LBound+UBound)/2;
Double err = 0;
int i = 0;
Calculate amortization payment
{}
Double MBalance is PVCalc (r, Period, MBound);.
ERR = MBalance-LoanBalance;
If (err > 0) {}
UBound = MBound ;}
If (err < = 0) {}
LBound = MBound ;}
MBound =(UBound+LBound)/2;
i ++ ;
}
While (err > 0.001 | err <-0,001 & & I < = 100);
return (MBound);
}
define the present value
public static double PVCalc (double rate, NPER, double PMT int) {}
Double pvpmt = pmt;
Double cpvpmt = 0;
for (int j = NPM; j > 0; j-) {}
for (int i = 1; i < = j; i ++) {}
pvpmt = pvpmt /(1+rate/12);
}
cpvpmt = cpvpmt + pvpmt;
pvpmt = pmt;
}
Return cpvpmt;
}
}
2. copy the .jar to 'C:\Hyperion\AnalysticServices\java\udf '.
3. has created a new MaxL file and run the script that runs:
create or replace function '@Amortize' as
'Amortization.Amort '.
Spec "@Amortize (spleen, period, balance)"
It shows: statement executed successfully.
4 then I tried to test in the following statement:
If (@isuda ("Time", "Test Date"))
"Depreciation Payment"=@Amortize (0.06, 360, 10000000);
endif;
And I got an error message as below:
Error compiling formula [amortization payment] (line 2): [)] without [()]
Could someone help me with this issue? 1 million thanks!The udf.policy file is located in the hyperion\products\essbase\essbaseserver\java directory and put the security on the java interface with Essbase points if there is a dev environment you can open the file with Notepad and go to the bottom of it. You will find a line
permission java.security.AllPermission;remove the / / (which comments out) and this will allow all java functions are allowed. After the change, you must restart the service Essbase

Hi, I am a newbie in oracle database,
I want to know if this is possible:
is it possible to build a sql (in string format), then run it inside a function defined by the user (NOT stored procedure)?
If so, are all versions of oracle database able to do this?
and it's samples?
and a stored procedure can be called inside a user-defined function?
Thank you!Hello
Forreging wrote:

Create a string that is a SQL command and then running it is called dynamic SQL .
You can do inside of a function, or a procedure. (Attention this: all procedures and functions is often called Stored Procedures .)
Everything you can do in a procedure, you can also do this in a function.If so, are all versions of oracle database able to do this?
Yes, all versions of Oracle behave this way.
and it's samples?
The [PL/SQL manual | http://download.oracle.com/docs/cd/B28359_01/appdev.111/b28370/dynamic.htm#sthref852] has many examples.
There are a lot of questions on this forum about PL/SQL. Enter "Dynamic SQL" in the serach box (top right of the Thread list page) to see [examples | http://forums.oracle.com/forums/search.jspa?objID=f75&q=dynnamic+SQL].and a stored procedure can be called inside a user-defined function?
Yes, it is done very often.

Writing user defined function the same way as the oracle functions
Hi guys,.
In one of the interviews, I saw the guy asked me to write a function defined by the user who will be the column name and the list of all values.
For example
Name: employees table
Column name: Employee_Name
Employee_name
Scott
Ivgun
Jack
Shane
The query must be in this marker
SELECT col_agg (Employee_name) emp_name of employees;
The output must be
Emp_names
Scott, ivgun, jack, shane
Please let me know if this is possible
Any suggestions will be much appreciated.
Thank you
RanjanYou certainly could write what a user defined aggregate function if you wish...
for example this function will consolidate channels in a CLOB...
create or replace type clobagg_type as object ( text clob, static function ODCIAggregateInitialize(sctx in out clobagg_type) return number, member function ODCIAggregateIterate(self in out clobagg_type, value in clob) return number, member function ODCIAggregateTerminate(self in clobagg_type, returnvalue out clob, flags in number) return number, member function ODCIAggregateMerge(self in out clobagg_type, ctx2 in clobagg_type) return number ); / create or replace type body clobagg_type is static function ODCIAggregateInitialize(sctx in out clobagg_type) return number is begin sctx := clobagg_type(null) ; return ODCIConst.Success ; end; member function ODCIAggregateIterate(self in out clobagg_type, value in clob) return number is begin self.text := self.text || value ; return ODCIConst.Success; end; member function ODCIAggregateTerminate(self in clobagg_type, returnvalue out clob, flags in number) return number is begin returnValue := self.text; return ODCIConst.Success; end; member function ODCIAggregateMerge(self in out clobagg_type, ctx2 in clobagg_type) return number is begin self.text := self.text || ctx2.text; return ODCIConst.Success; end; end; / create or replace function clobagg(input clob) return clob deterministic parallel_enable aggregate using clobagg_type; / SQL> select trim(',' from clobagg(ename||',')) as enames from emp; ENAMES ----------------------------------------------------------------------------------- SMITH,ALLEN,WARD,JONES,MARTIN,BLAKE,CLARK,SCOTT,KING,TURNER,ADAMS,JAMES,FORD,MILLER SQL> ed Wrote file afiedt.buf 1 with t as 2 (select 'PFL' c1, 0 c2,110 c3 from dual union all 3 select 'LHL', 0 ,111 from dual union all 4 select 'PHL', 1, 111 from dual union all 5 select 'CHL', 2, 111 from dual union all 6 select 'DHL', 0, 112 from dual union all 7 select 'VHL', 1, 112 from dual union all 8 select 'CPHL', 0, 114 from dual union all 9 select 'WDCL', 1, 114 from dual union all 10 select 'AHL' ,2 ,114 from dual union all 11 select 'NFDL', 3, 114 from dual) 12 -- 13 -- end of test data 14 -- 15 select trim(clobagg(c1||' ')) as c1, c3 16 from (select * from t order by c3, c2) 17 group by c3 18* order by c3 SQL> / C1 C3 ------------------------------ ---------- PFL 110 LHL CHL PHL 111 DHL VHL 112 CPHL AHL NFDL WDCL 114
OK, it's more that a function it uses a type of object that connects in operation internal to the ODCI... but it does what you ask. :)

User-defined function: BAD ARGUMENT TYPE, ERROR
I am creating a function defined by the user, named DOTAN, to calculate the angle between two vectors X and Y. The UDF looks like this: DEFINE (' DOTHAN (X, Y) = ACOS (DOT (X, Y) / (ABS (X) * ABS (Y)))')--> (see pic attached to the actual Calculator display). The problem is that I can not set because as soon as I hit ENTER I get the warning: DEFINE ERROR: wrong Type of Argument. I tested each component separately and I am sure that the problem is with the help of DOT (X, Y) inside a UDF, but I don't know why. Maybe I'm missing some setting related to the use of functions which take an argument that is greater than 1 inside a UDF. Just guessing. Any idea?
Thank you
for some reason, the DOWRY is a commandment and not a function for the 50G.
You cannot use DOT in a function, you maybe wrote a program
in RPL
'--> x, y ' x y DOT XY ABS ABS * / ACOS ' ""DOTHAN"STO
[3.0] [0.3] DOTAN
back 90 degreesI never use the algebraic mode but I guess it's the same thing with a program...

User defined function in the cases in article
Hello
I have a function that returns in priview:
(1,2,3,4)
Now I am using this function in SQL where clause
Selection of the debug version where id in debug.debug_process)
Executing select I am getting ORA-01722 invalid number, I understand the functions return not only numbers but character symbols too "(en).
It is posible to use the function defined by the user that do not return a NUMBER CASE statement IN clause? If this is not the case, what advice can I sugest for a list of values for use in the Clause IN?
ID.
Thank you!
The SQL IN clause requires a set as the parameter type.
This means that the function used must provide a suitable type.
Examples:
SQL> create or replace type TNumberSet as table of number; 2 / Type created. SQL> SQL> create or replace function FunkyFoo return TNumberSet as 2 begin 3 return( 4 new TNumberSet(7369,7499,7902) 5 ); 6 end; 7 / Function created. SQL> SQL> select 2 * 3 from emp 4 where empno in(select * from table(FunkyFoo)); EMPNO ENAME JOB MGR HIREDATE SAL COMM DEPTNO ---------- ---------- --------- ---------- ------------------- ---------- ---------- ---------- 7369 SMITH CLERK 7902 1980/12/17 00:00:00 800 20 7499 ALLEN SALESMAN 7698 1981/02/20 00:00:00 1600 300 30 7902 FORD ANALYST 7566 1981/12/03 00:00:00 3000 20 SQL> SQL> select 2 * 3 from emp 4 where TNumberSet(empno) submultiset of (FunkyFoo); EMPNO ENAME JOB MGR HIREDATE SAL COMM DEPTNO ---------- ---------- --------- ---------- ------------------- ---------- ---------- ---------- 7369 SMITH CLERK 7902 1980/12/17 00:00:00 800 20 7499 ALLEN SALESMAN 7698 1981/02/20 00:00:00 1600 300 30 7902 FORD ANALYST 7566 1981/12/03 00:00:00 3000 20 SQL>

10g - hide, the report contains the oracle user-defined function
Hi, experts,
of http://obiee101.blogspot.com/2008/07/obiee-cache-management.html
Reasons why a request is not added to the Cache:
•The-cacheable SQL element. If a SQL query contains Current_Timestamp, Current_Time, Rand, Populate, or a parameter marker, then it is not added to the cache.
•The-cacheable table. Physical in the Oracle BI Server repository tables can be marked "cacheable". If a query refers to any non-cacheable table then the results of the query will not be added to the cache.
•Cache hit. In general, if the query gets a cache hit on a previously cached query, then the results of the current query are not added to the cache. The exception is query that is aggregated at winding hits hits.
Result set is too large.
Query is canceled. This can happen by explicit cancellation of Oracle BI Presentation Services or Administration, or implicitly through timeout tool.
•Oracle BI Server is clustered. Queries coming into family "seeding cache" spread in the whole of the cluster. Other queries continue to be stored locally. Therefore, even if a query may be cached on the Server BI Oracle 1 node, it can not be on the node Server BI Oracle 2.
I would like to know
If the application (report on the dashboard) calls a function defined by the user to oracle, the cache can be created and saved for this report?
Thank you very much!Hello stephen,.
If the application (report on the dashboard) calls a function defined by the user to oracle, the cache can be created and saved for this report?
Yes, it is cached... function defined in the database is called OBIEE is cached and saved.
More information and example can be found here http://oraclebizint.wordpress.com/2007/09/10/oracle-bi-ee-10133-support-for-native-database-functions-and-aggregates/
