How to use LIKE function with a parameter in Oracle REPORT builder??

how could i use parameter inside a LIKE function in Oracle reports builder?
it works in SQL plus, but not in report builder!!
Example:
select code,desc from item_master where desc
like '%&give_desc%'; ---works in SQL
like '%:give_desc%' ---doesn't work in report builder!!

Hi Renil,
You will need to use the wildcard character (%) and the concatenation character (||) to join to your user parameter.
i.e. like '%'||:give_desc||'%'

How to use TRUNC function with dates in Expression Builder in OBIEE.

Hi There,
How to use TRUNC function with dates in Expression Builder in OBIEE.
TRUNC (SYSDATE, 'MM') returns '07/01/2010' where sysdate is '07/15/2010' in SQL. I need to use the same thing in expression builder in BMM layer logical column.
Thanks in advance

use this instead:
TIMESTAMPADD(SQL_TSI_DAY, ( DAYOFMONTH(CURRENT_DATE) * -1) + 1, CURRENT_DATE)

How to use aggregate function with Date

Hi All,
I have a group of date from that is it possible to Max and Min of date.
I have tried like this but its errored out <?MIN (current-group()/CREATION_DATE)?>.
I have also tried like this but it doesnt works
<?xdoxslt:minimum(CREATION_DATE)?>
Is it possible to use aggregate function with date values.
Thanks & Regards

Hi KAVI PRIYA,
if date is not in cannonical format, how can we change it in BI publisher, then how to calcualte minimum and as well as maximum.
please advise me,

How to use analytic function with aggregate function

hello
can we use analytic function and aggrgate function in same qurey? i tried to find any example on Net but not get any example how both of these function works together. Any link or example plz share with me
Edited by: Oracle Studnet on Nov 15, 2009 10:29 PM

select
t1.region_name,
t2.division_name,
t3.month,
t3.amount mthly_sales,
max(t3.amount) over (partition by t1.region_name, t2.division_name)
max_mthly_sales
from
region t1,
division t2,
sales t3
where
t1.region_id=t3.region_id
and
t2.division_id=t3.division_id
and
t3.year=2004
Source:http://www.orafusion.com/art_anlytc.htm
Here max (aggregate) and over partition by (analytic) function is in same query. So it means we can use aggregate and analytic function in same query and more than one analytic function in same query also.

How to use trignometric functions with MIDP1.0

HI ALL!
We designed midlet to run on a mobile phone using MIDP1.0. We have some additional trignometrical classes to integerate with the midlet. But we got astonished when we didn't find any trignometrical function in MIDP1.0 & CLDC1.0. It is now is a great panic for us.
It is very unbelievable that Sun Microsystem doesn't provide such classes with J2ME!!
Is there any way to define or get a free-ware trignometrical classes to use?
We hope reply from this Forum soon!

Mmmm....,J2ME currently doesn't support doubles,floats and if you want to use trigonometric functions then you will use cos, sin, tan, ctan,atan,acos,asin and this means doubles and floats....

How to use Substring function with Case statement.

Hello Everyone,
I have one requirement where I have to use substring function on the field for report criteria.
E.G.
I have Branch Name Field where I have all branch names information, Now some of the branch names are too big with some extension after the name .
now i want to substing it but the character length varies for each branch.
so is there any way where we can use case statement where we can define that if branch name character are exceeding some value then substing it with this length.

Try something like this:
CASE WHEN LENGTH(tablename.Branch_Name) > n THEN SUBSTRING(...) ELSE tablename.Branch_Name END
where n is the number of characters you want to start the break.

Oracle Data Mining - How to use PREDICTION function with a regression model

I've been searching this site for Data Mining Q&A specifically related to prediction function and I wasn't able to find something useful on this topic. So I hope that posting it as a new thread will get useful answers for a beginner in oracle data mining.
So here is my issue with prediction function:
Given a table with 17 weeks of sales for a given product, I would like to do a forecast to predict the sales for the week 18th.
For that let's start preparing the necessary objects and data:
CREATE TABLE T_SALES
PURCHASE_WEEK DATE,
WEEK NUMBER,
SALES NUMBER
SET DEFINE OFF;
Insert into T_SALES
(PURCHASE_WEEK, WEEK, SALES)
Values
(TO_DATE('11/27/2010 23:59:59', 'MM/DD/YYYY HH24:MI:SS'), 1, 55488);

There are a lot of linear regression models and approaches for sales forecast out on the market, however I will focus on what oracle 11g offers i.e. package SYS.DBMS_DATA_MINING to create a model using regression as mining function and then, once the model is created, to apply prediction function on the model.
Therefore I'll have to go through few steps:
i) normalization of data
CREATE OR REPLACE VIEW t_sales_norm AS
SELECT week,
sales,
(sales - 91423.95)/27238.3693126778 sales_norm
FROM t_sales;
whereas the numerical values are the mean and the standard deviation:
select avg(sales) from t_sales;
91423.95
select stddev(sales) from t_sales;
27238.3693126778
ii) auto-correlation. For the sake of simplicity, I will safely assume that there is no auto-correlation (no repetitive pattern in sales among the weeks). Therefore to define the lag data I will consider the whole set:
CREATE OR REPLACE VIEW t_sales_lag AS
SELECT a.*
FROM (SELECT week,
sales,
LAG(sales_norm, 1) OVER (ORDER BY week) L1,
LAG(sales_norm, 2) OVER (ORDER BY week) L2,
LAG(sales_norm, 3) OVER (ORDER BY week) L3,
LAG(sales_norm, 4) OVER (ORDER BY week) L4,
LAG(sales_norm, 5) OVER (ORDER BY week) L5,
LAG(sales_norm, 6) OVER (ORDER BY week) L6,
LAG(sales_norm, 7) OVER (ORDER BY week) L7,
LAG(sales_norm, 8) OVER (ORDER BY week) L8,
LAG(sales_norm, 9) OVER (ORDER BY week) L9,
LAG(sales_norm, 10) OVER (ORDER BY week) L10,
LAG(sales_norm, 11) OVER (ORDER BY week) L11,
LAG(sales_norm, 12) OVER (ORDER BY week) L12,
LAG(sales_norm, 13) OVER (ORDER BY week) L13,
LAG(sales_norm, 14) OVER (ORDER BY week) L14,
LAG(sales_norm, 15) OVER (ORDER BY week) L15,
LAG(sales_norm, 16) OVER (ORDER BY week) L16,
LAG(sales_norm, 17) OVER (ORDER BY week) L17
FROM t_sales_norm) a;
iii) choosing the training data. Again, I will choose the whole set of 17 weeks, as for this discussion in not relevant how big should be the set of training data.
CREATE OR REPLACE VIEW t_sales_train AS
SELECT week, sales,
L1, L2, L3, L4, L5, L6, L7, L8, L9, L10,
L11, L12, L13, L14, L15, L16, L17
FROM t_sales_lag a
WHERE week >= 1 AND week <= 17;
iv) build the model
-- exec SYS.DBMS_DATA_MINING.DROP_MODEL('t_SVM');
BEGIN
sys.DBMS_DATA_MINING.CREATE_MODEL( model_name => 't_SVM',
mining_function => dbms_data_mining.regression,
data_table_name => 't_sales_train',
case_id_column_name => 'week',
target_column_name => 'sales');
END;
v) finally, where I am confused is applying the prediction function against this model and making sense of the results.
On a search on Google I found 2 ways of applying this function to my case.
One way is the following:
SELECT week, sales,
PREDICTION(t_SVM USING
LAG(sales,1) OVER (ORDER BY week) as l1,
LAG(sales,2) OVER (ORDER BY week) as l2,
LAG(sales,3) OVER (ORDER BY week) as l3,
LAG(sales,4) OVER (ORDER BY week) as l4,
LAG(sales,5) OVER (ORDER BY week) as l5,
LAG(sales,6) OVER (ORDER BY week) as l6,
LAG(sales,7) OVER (ORDER BY week) as l7,
LAG(sales,8) OVER (ORDER BY week) as l8,
LAG(sales,9) OVER (ORDER BY week) as l9,
LAG(sales,10) OVER (ORDER BY week) as l10,
LAG(sales,11) OVER (ORDER BY week) as l11,
LAG(sales,12) OVER (ORDER BY week) as l12,
LAG(sales,13) OVER (ORDER BY week) as l13,
LAG(sales,14) OVER (ORDER BY week) as l14,
LAG(sales,15) OVER (ORDER BY week) as l15,
LAG(sales,16) OVER (ORDER BY week) as l16,
LAG(sales,17) OVER (ORDER BY week) as l17
) pred
FROM t_sales a;
WEEK, SALES, PREDICTION
1, 55488, 68861.084076412
2, 78336, 104816.995823913
3, 77248, 104816.995823913
4, 106624, 104816.995823913
As you can see for the first row there is a value of 68861.084 and for the rest of 16 values is always one and the same 104816.995.
Question: where is my week 18 prediction ? or maybe I should say which one is it ?
Another way of using prediction even more confusing is against the lag table:
SELECT week, sales,
PREDICTION(t_svm USING a.*) pred
FROM t_sales_lag a;
WEEK, SALES, PREDICTION
1, 55488, 68861.084076412
2, 78336, 75512.3642096908
3, 77248, 85711.5003385927
4, 106624, 98160.5009687461
Each row out of 17, its own 'prediction' result.
Same question: which one is my week 18th prediction ?
Thank you very much for all help that you can provide on this matter.
It is as always highly appreciated.

END;
--to show the out put
select class, attribute_name, attribute_value, coefficient
from table(dbms_data_mining.get_model_details_svm('MODEL_SVMR1')) a, table(a.attribute_set) b
order by abs(coefficient) desc
-- to get predicted values (Q1)
SELECT PREDICTION(MODEL_SVMR1 USING *
) pred
FROM data_4svm a;
Here i am not sure how to predict B values . Please suggest the proper usage . Moreover In GUI (.NET windows form ) how user can give input and system can respond using the Q1

It's hard for me to say what you're doing wrong when I don't know what you're doing. Post a complete test script that people can run to re-create the problem and test their ideas. Include a function definition, CREATE TABLE and INSERT statements for any of your own tables (if necessary), and the results you want to get from that data, as well as your query.
How to pass the dates? Can any one help me in this regard.You can call the function like this:
SELECT fun1 (hiredate) AS fun1_results

Post Author: jsanzone
CA Forum: WebIntelligence Reporting
xuanthuyit:
Apparently =count() [and use of a where] was permissible in previous versions of BusObjects, however, things in XI are different (as other users tell me, being XI is my first experience w/ BusObj...), so anyhow, here is the solution to your question.
You will have have to create two variables for each condition you have. One variable will be the "helper" and the other variable will be the "worker". For instance, create a variable called channel_x and the formula: =if(channel="haney";<metric>;0) (where "haney" is the name of your organization and <metric> is the metric you are using to count or sum things in your report). Once channel_x is saved create another variable called channel_x_count and the formula: =sum([channel_x]). Once channel_x_count is saved, then on your report towards the bottom you can use the Template bar to drag in a new table (perhaps you want to use the Horizontal Table type), and then you can drag channel_x_count into your new table. You will have to repeat the creations of more channel_x type variables (maybe call it channel_y and channel_y_count) or something more descriptive, but in any case substitute the "haney" constant for the next store you want to track, etc, etc.

How to use matlab function with labview?

Hello,
I just want to use some matlab functions like floor(),ones()... in my labview code, who can tell me how to do it?
I want to only install MCR in my PC, so MATLAB script node can not work because it need matlab installed.
Thanks
Solved!
Go to Solution.

floor() exists on the standard labview pallet already and the ones() function would be fairly simple to reproduce. If you only need a few basic functions repost asking for direction on recreating those specific methods. However, you're right - there is not a direct way to use compiled matlab code in labview without full matlab and the math script nodes. If you're really desparate to reuse some some exisiting IP there are C++ alternatives that implement many of the same methods and syntax as matlab (http://arma.sourceforge.net/faq.html). I'm fairly sure there are other tools that attempt to translate matlab code into pure c functions, both of which can be called via a DLL from within labview: https://decibel.ni.com/content/docs/DOC-9076
Alternatively, here is an all NI linear algebra solution: http://sine.ni.com/nips/cds/view/p/lang/en/nid/210525

How to use MAX() function with date field

Hi Frzz,
I have created a Graphical calculation view in which i have multiple records for each employee with different dates. But my requirement is to take the records which have maximum date.
I have converted the date into Integer and applied the MAX() function. But still am getting multiple records.
Is there is any other way we can achieve this requirement in Graphical Calculation view?? Your suggestion will really help me.
Thank you.
Krishna.

Hmm... what have you tried out so far?
Look, I took the effort and created a little example, just for you
Assume we have a table that contains the logon dates of users.
Every line contains the logon date and some info on the user.
Very much like a not-normalized log file could look like.
Now, the output we want is: one line per user with the most current logon time.
Not too difficult:
1. Have a aggregation node that gives you the distinct user details - one line for every user:
2. Have another aggregation node that gives you the last (MAX) logon date per user:
Finally you do a 1:1 join on the USER_ID and map the result to the output.
Easy as pie

How to use auto increment with "nchar" data type

Hello
I have a table that I want the value in one column to be generated automatically with "T-XXX" pattern which
"XXX" is a number. Can Microsoft SQL Server do that?

Hello,
Not directly.
You could use an integer column with "Identity" and then add a calculated column to generate the required pattern, like
'T' + convert(varchar, YourIntColumn)

How to use NODIM func with out it's values being rounded

I created a new calculated key figure in Query Designer 3.x, and used the function NODIM() - Value with out dimensions. When I use this function, the values are rounding off to the nearest value.
For example, I have a value 0.000075 US$, when I use NODIM function the value is displayed as 0.000080. Value is getting rounded to nearest value.
I tried using absolute value it did not work.
Can any one tell me how to use NODIM function with out it's value being rounded to nearest value.
Thanks,

Hi,
According to your description, you might want that "Notice" field has a default value when form is created and users can be able to change the value of that
field.
As a workaround, you can add an action rule in “Name” field via InfoPath to fill the default value in “Notice” field only when “Name” field is not blank and “Notice”
field is blank.
Settings of the rule are as below, you can modify it based on your need:
Here is a link about how to add an action rule in InfoPath form, you can use it as a reference:
