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.

hope helps you.

Problem in passing varchar2 parameter to Evaluate function in OBIEE

Hi there,
This is regarding an issue while passing parameter in EVALUATE function.
I have to call a function with varchar parameters. parameter are nothing but my table column values.
I've created session variables which holds value from my table column values.
for eg:
EVALUATE('REP1_FIRSTMONTH_F(%1)' AS CHARACTER ( 30 ), VALUEOF (NQ_SESSION."month"))
so whenever i call function using EVALUATE in OBIEE. i hve to pass ' ' (single quotes) for my varchar values. without this , i'm facing error stating :
*State: HY000. Code: 10058. [NQODBC] [SQL_STATE: HY000] [nQSError: 10058] A general error has occurred. [nQSError: 59015] The requested column PERIOD0 does not exist in this table. (HY000)*
If i'll give parameter within single quotes in my dashboard prompt. it is working fine, but fails without the quotes.
kindly help me in solving this issue.
Thanks - Vijay
NOTE: parameter are from column values.

Hi
Anyone has any input for the above issue??. Please share.

Evaluate function doesn't work with Static values

Hi All,
I have been trying to call a evaluate function and have been successfully in calling it..but i face problem when i pass any static values to it...
For eg
when i try calling the function using one of the columns...it works fine
Evaluate('dbo.Hello(%1)',"Dim table_name"."Department" )
the function normally changes it to upper case.so i get all the value in the column in department in upper case.
but when i call any static value like
Evaluate('dbo.Hello(%1)','hello') it throws the following error..
[nQSError: 43113] Message returned from OBIS. [nQSError: 43119] Query Failed: [nQSError: 42015] Cannot function ship the following expression: Evaluate( dbo.Hello(%1),'hello') . (HY000)
Can any one please help me in this

Sort order issue in with Evaluate function ( Next Quarter measure)

Hi All,
I have report requirement where I have to show measures for a particular geography for previous, current and next quarters in a pivotal view.
---------------Previous Quarter| Current Quarter| Next Quarter
Geography
ABC|xx|xx|xx
PQR|xx|xx|xx
XYZ|xx|xx|xx
Next quarter values are displayed for other geography like
ABC value is shown for XYZ and XYZ value is shown for PQR
I have derived measure for pervious quarter using Time Series Function > Ago function,
However the problem is with next quarter. I used following Evaluate Function to derive measure for next quarter.
EVALUATE ('LEAD(%1,1) over (order by %2)' AS DOUBLE PRECISION , X, Y)
Here X = Measure and Y = Level (Quarter)
X is delta of two other measures A and B.
X = (A- B)
Thanks,

Hi user10300020,
That's a fairly common problem with months that happens regardless of database source.
In the logical layer of OBIEE you can specify the sort order on the month name column. Just double click on the month name column and look for the option to set sort order based on a different column. I typically sort the month name based on the month number.
Give that a shot and tell me if it works.

EVALUATE Function Obiee

Hi!
My database is Essbase. I need to choose members of different hierarchies. I get the following formula.
EVALUATE ('Intersect (% 1.dimension.members, {[Account1], [Account2]}) "," Account "." Gen1, Account ")
I see different accounts of different hierarchies.
The problem is that members Account1, Account2 are Identifiers and want to see the descriptions.
Is there any way to show IDs descriptions choosing their IDs in the formula EVALUATE?
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 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

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.

Evaluate function in OBIEE

Hi All,
I tried using Evaluate and Evaluate_Aggr in the column formula of a report.
Evaluate_Aggr() is erroring saying the dimension Work Order is incorrectlly defines logical Table Source Mapping for a dimension of Work Order. If I revoke the implicit fact coniguration on this Subject Area which I have, the report executes as expected. But this implicit configuration is required in my scenario for other reports to work.
Using Evaluate() works perfectly.
Can anyone help me in fixing this?
Shld I add any other configuration in the RPD to resolve this issue?
Thanks

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!

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.
