ORACLE EQUVALENT OF "EVALUATE" FUNCTION OF FOXPRO? or any other solution

I have a string (varchar2) holding the following '39 + (25 /3) - 200' ,which is a argument to a function returning the value (numeric) of the expression contained in the string. for eg.
Declare
varstr varchar2(2000) := '10 + (75/3)*10';
value number;
begin
value := function(varstr);
--output should be 40 .i.e value := 40;
end;
How do I get it?

Quick answer:
Use the dbms_sql package to dynamically select the expression from the dummy table "dual".

Exclamation mark appears instead of photo. Recently upgraded from i mac to Macbook air and all was transferred over. I have run all the repair and rebuild functions in iphoto. Any other solution?

Since iPLM failed to help try the following:
Starting over from scratch with new library
Start over with a new library and import the Originals (iPhoto 09 and earlier) or the Masters (iPhoto 11) folder from your original library as follows:
1. Open the library package like this.
2. Launch iPhoto with the Option key held down and, when asked, select the option to create a new library.
3. Drag the subfolders of the Originals (iPhoto 09 and earlier) or the Masters (iPhoto 11) folder from the open iPhoto Library package into the open iPhoto window a few at a time.
This will create a new library with the same Events (but not necessarily the same Event names) as the original library but will not keep the metadata, albums, books slideshows and other projects.
Note: your current library will be left untouched for further attempts at a fix if so desired.

Can we use Evaluate function in Prompt

Hi all
Can we use Evaluate Function in Dashboard Prompt?
I need some exposure on how to use it.
I am working on a HRMS-OLTP Source where I need to work with Oracle Functions from OBIEE.
IF somebody can tell me that, It will be a favour for me....
ThanQ
Anand V

Hi All,
Here's an example of how to use evaluate. This use calls the Oracle TO_DATE function: EVALUATE('TO_DATE(%1,%2)' as DATE, '03/03/2009', 'MM/DD/YYYY')
Here's how it works: EVALUATE( '<FUNC>' AS <DATATYPE>, VALUE1,VALUE2,etc)
FUNC) Is the syntax for the function you are calling. Any parameters have to be replaced by %<number>, where number refers to the order in which you specify your parameters.
DATATYPE) The datatype that the function will evaluate to. In this case, DATE.
VALUE1) The latter part of the formula is a comma separated list of all the parameters used in the function. In this case, it's the date I want to cast
VALUE2) This is the second parameter. You need as many as you referenced in your function. In this case, it's the date format.
Good luck and if you found this post useful, please award points!
Best regards,
-Joe

Syntax for Evaluate function in OBIEE

Hi
I have browsed through the docs but couldn't find syntax for Evaluate function. Could someone pass me the full syntax and if possible a helpful example against essbase.
Thanks

Hi
definitely
syntax:- EVAULATE('your db function(%1,%2)', parameter list)
here %1 and %2 are the no.of parameters (columns or may constant values) to be passed for the db-function
if you have 3 parameters then you need to use %3 also.. means the columns to be passed.
following exapmples are for ORACLE db,
ex1: EVALUATE('upper(%1)', 'kishore kumar') gives the result as -> KISHORE KUMAR
ex2: EVALUATE('upper(%1)', 'Markets.Region') here Markets.Region is column.
you also can call the user-defined functions through evaulate
EVALUATE('functioname(%1,%2), column1, column2)
the above function has 2 parameters to be inputted
Thanks & Regards

Equivalent of to_date function in Ms SQL and using it in Evaluate function

Hi,
I am trying to find out a function in MS SQL which is equivalent to to_date function in oracle. Please find below the advanced filter i am trying to use in OBIEE.
Evaluate('to_date(%1,%2)' as date ,SUBSTRING(TIMES.CALENDAR_MONTH_NAME FROM 1 FOR 3)||'-'||cast(TIMES.CALENDAR_YEAR as char(4)),'MON-YYYY')>=Evaluate('to_date(%1,%2)' as date,'@{pv_mth}'||'@{pv_yr}','MON-YYYY') and Evaluate('to_date(%1,%2)' as date ,SUBSTRING(TIMES.CALENDAR_MONTH_NAME FROM 1 FOR 3)||'-'||cast(TIMES.CALENDAR_YEAR as char(4)),'MON-YYYY') <=timestampadd(sql_tsi_month,4,Evaluate('to_date(%1,%2)' as date,'@{pv_mth}'||'@{pv_yr}','MON-YYYY'))
The statement above works fines with oracle DB with to_date function. The same statement throws an error with MS SQL since to_date is not a built in function.
With MS SQL I tried with CAST, not sure how to pass parameters %1 and %2.
Please help me how to use Evaluate function and passing parameters along with to_date funtion in MS SQL.
Regards!

Hi,
please refer to this thread for useful information on using to_char and to_date functions of oracle in MS SQL server:

Best practices on using EVALUATE functions

hi, experts,
I wanna know what is the best practices on using EVALUATE functions on obiee (calling oracle user defined functions)
I found that if I use evaluate functions in Answers,
obiee will construct a sql behind and then execute.
sometimes, obiee contructs some unexpected sqls, and returns errors.
so, is it better to use EVALUATE functions in logical columns ?
thanks

EVALUATE('DB_Function(%1)' as returntype, {Comma separated Expression})
even when used in Logical columns, its gonna fire the same sql.

Evaluate function error! how to use it properly?

Hi,
I used evaluate function to use a user-defined stored function present in my DB. But I ended up with this error.
Error Codes: OPR4ONWY:U9IM8TAC:OI2DL65P
State: HY000. Code: 10058. [NQODBC] [SQL_STATE: HY000] [nQSError: 10058] A general error has occurred. [nQSError: 17001] Oracle Error code: 1722, message: ORA-01722: invalid number at OCI call OCIStmtExecute: select distinct T119198.BCREFNO as c1, T119198.MATURITY_DATE as c2, T119198.BILL_DUE_AMT as c3, test_eval('"Contract BC Parameters Fact"."Bill Amt Lcy"') as c4 from BCTBS_CONTRACT_MASTER T119198 /* BC_BCTBS_CONTRACT_MASTER */ order by c1, c2, c3, c4. [nQSError: 17011] SQL statement execution failed. (HY000)
I used the following evaluate function in my report under Edit Column Formula of the particular field.
EVALUATE('test_eval(%1)','"Contract BC Parameters Fact"."Bill Amt Lcy"')
The test_eval function in my DB takes one parameter of type number and returns a number. The "Contract BC Parameters Fact"."Bill Amt Lcy" field is of DOUBLE type as found in BMM layer.
I wish to know if I am right by placing the evaluate function in report or should I use it in BMM layer? Can I get anybodies assistance in knowing how to arrive at using a DB user-defined function in a report.
Regards,
The MasterMind.

hi,
This is the syntax

Srini,
Here is my issue
I want to implement below function in obiee.It takes the month from the column and appends the current year .so basically if the column has the value 01/12/12.It becomes 01/12/13.P_year is a current year variable.I am having issues in writing the above code in obiee.I am using the below in obiee which is giving the below error.

Can Evaluate function return object type

Hi
Evaluate function can be used to call db functions in OBIEE. I have a function which returns an object ( pl/sql table).
Created a simple report in Oracle Answers and added following in one of the columns
evaluate( 'get_ccid(%1)' as t_ccid , @{p_request})
When I try to run this in Oracle answers, getting syntax error. If same function returns varchar or number it works well.

evaluate( 'get_ccid(%1)' as t_ccid , @{p_request})Eakta, You syntax seems to be wrong here. What type of data your presentation variable contains here ?? You are saying its working fine with Number datatype..so can you try..somthing like below with some default value..
EVALUATE('get_ccid(%1)',@{p_request}{2})
OR
EVALUATE('get_ccid(%1)' as varchar(250),@{p_request}{ABC})
Also, refer

Evaluate function problem

I have a problem with EVALUATE function in OBIEE.
I passed two parameters. Number is numeric and Name is varchar.
Evaluate('DWH.PKG_ITEM_FUNCTION.PS_LAW(%1,%2)', "Book"."Item"."Number", "Book"."Item"."Name" )
I get the following error:
[nQSError: 22027] Union of non-compatible types.
How can I solve this?
Many thanks in advance.

hi stanisa,
It is a bug in 10g,here it goes
--> While using Evaluate function, common errors like “Union of non-compatible types. (HY000)”.
I believe this is a bug in the Evaluate function implementation. One must cast all the arguments to the same data type before passing them as arguments.

How to use evaluate function for sql server function

Hi Team,
We have imported a column(date dtat type) from SQL server cube . By default it imported as varchar,. We have three option in physical layer for this column(Varchar,Intiger,unknown)
So we want to convert this column into date.can we use evaluate or there is any option to do that.?

Hi,
I am not sure your requirement. But how pass evaluate function obiee?
syntax:- EVAULATE('your db function(%1,%2)', parameter list)
here %1 and %2 are the no.of parameters (columns or may constant values) to be passed for the db-function
if you have 3 parameters then you need to use %3 also.. means the columns to be passed.
following exapmples are for ORACLE db,
ex1: EVALUATE('upper(%1)', 'satya ranki reddy') gives the result as -> SATYA RANKI REDDY
ex2: EVALUATE('upper(%1)', 'Markets.Region') here Markets.Region is column.
you also can call the user-defined functions through evaulate
EVALUATE('functioname(%1,%2), column1, column2)
the above function has 2 parameters to be inputted
Hope this help's
Thanks

Using EVALUATE function

Hello to all!
I have a problem using EVALUATE function in BI report column. In my schema I have created stored function.
Call looks like
evaluate('PKG1.GET_STAMP_DATE(%1)' as date,"Доп. аналитики"."Документ")
Состояние: HY000. Код: 10058. [NQODBC] [SQL_STATE: HY000] [nQSError: 10058] A general error has occurred. [nQSError: 17001] Oracle Error code: 904, message: ORA-00904: "PKG1"."GET_STAMP_DATE": invalid identifier at OCI call OCIStmtExecute. [nQSError: 17010] SQL statement preparation failed. (HY000)
I tried function IN package and OUTSIDE package. The same.
What's wrong???
Tnanks in advance...

Hi,
Check this function in database wether it is working or not.
The identifier (column name, function, …) entered is invalid or unknown.
This can have a number of reasons:
It can be an unknown function, a column name that does not belong to a table, an invalid table alias, …
The following function is not known
SQL> select unknown_function from dual;select unknown_function from dual
*ERROR at line 1:
ORA-00904: "UNKNOWN_FUNCTION": invalid identifier
The following column does not exist in the table:
SQL> select X1 from dual;select X1 from dual
*ERROR at line 1:
ORA-00904: "X1": invalid identifier
Please refer the below thread might be help u..

Can we use Evaluate Function in Dashboard Prompt

Hi
Can anybody tell me
Can we use Evaluate Function in Dashboard Prompt.
If yes...How
Thanks in Adv

Yes ! You Can!
while creating the dashboard prompt, under "Show" pick SQL results and you write the SQL statement and include the EVALUATE function.
I have several such examples. Most of of dashboard pages are parameter driven.
1. 1st paratmeter - users specify the dates
2. 2nd parameter - constrains the results for the period specified in 1st paramter and my SQL for 2nd paramter looks like this -
SELECT table1.column1
FROM table, datedim1, table1,table2
WHERE datedim1.date BETWEEN EVALUATE( 'TO_DATE(%1,%2)','@{presentation variable1}','dd/mm/yyyy') AND EVALUATE('TO_DATE(%1,%2)', '@{presentation variable 2}','dd/mm/yyyy')

Evaluate function not working in obiee 11.1.1.7

Hi all,
I have completed In-place upgrade from obiee 11.1.1.5 to 11.1.1.7.
After this I am getting an error while running reports,which is created by using evaluate function.
[nQSError: 43113] Message returned from OBIS. EVALUATE_SUPPORT_LEVEL inside NQSConfig.INI is not set to support EVALUATE
In my NQSconfig.ini I coundnt find EVALUATE_SUPPORT_LEVEL. So I have added below content in NQSConfig.ini file
# EVALUATE_SUPPORT_LEVEL:
# 1: evaluate is supported for users with manageRepositories permssion
# 2: evaluate is supported for any user.
# other: evaluate is not supported if the value is anything else.
EVALUATE_SUPPORT_LEVEL = 2;
After that I restarted BI services. But still I am facing same error.
Guide me regarding this.
Thanks in advance.

Are you using any parameter like % or / , If you are using,Then it is a bug in 11.1.1.7,Check the below URL for more info.

Service Bus 12c Class not found 'oracle.tip.pc.services.functions.ExtFunc'

Hi,
Did anyone came across this issue with Class not being found for XSLT Function used in transformer on 12c OSB.
I'm using oraext:sequence-next-val and have configured as below:
namespace-uri:http://www.oracle.com/XSL/Transform/java/oracle.tip.pc.services.functions.ExtFunc
namespace-prefix: oraext
Not sure why at runtime I'm getting below error, as the same was working fine in 11g OSB Domain.
XML-22045: (Error) Extension function error: Class not found 'oracle.tip.pc.services.functions.ExtFunc'

Have you restarted servers after putting jar in $Domain_Home/lib directory? Also try after explicitly adding this jar in classpath by editing server startup script (startManagedWeblogic.cmd or .sh) or in domain env setting script (setDonainEnv.cmd or .sh) and restarting the servers.
