How to set variable values in Stored Procs

Hi all,
please excuse my newbie questions - I've spent too long using SQL Server......
Anyway,
I'm playing with SP basics and was wondering how I can set a variable value in a stored proc, ideally getting a value from a table or some select .
for instance...........
CREATE OR REPLACE PROCEDURE RPT_SP_ANT_TESTING
P1 IN NUMBER,
P2 IN VARCHAR2
IS
TmpNum NUMBER;
TmpStr VARCHAR2(255);
BEGIN
--How do set these?
SET TMPNUM := SELECT Count( * ) FROM ALL_TABLES;
SET TMPSTR := P2 + '_APPENDED';
INSERT INTO TEST_TABLE
( STRINGFIELD, NUMBERFIELD )
VALUES
( TmpStr, TMPNUM )
END;
Regards
DC

Some ways are...
setting directly
x := 1;
setting from a select use INTO clause
select 1 into x from dual
setting from a select into a collection type use BULK COLLECT INTO
select name bulk collect into lName from your_table.
It would be better if you read the document.
Thanks,
Karthick.

How to set variables values via VBA.

Anybody please help.
How to set variables values via VBA in workbook. SAP Netweaver 2004s.

Pass variable values with VBA and BI 7.0 funtions to Query
At first a remark u2013 Iu2019ve read a lot of threads saying that passing values to a query can be done by using VBA code only. Iu2019ve tested it but Iu2019m not sufficient with the new BEX 7.0 API and therefore I use a mixture of BEX 7.0 funtionality and VBA. I create a BEX 7.0 design item button passing the values to a query u2013 I hide this button somewhere on the sheet or on a hidden sheet and I then raise the event to click the button from VBA code. Works fine and the maintenance is easier if something changes in the API in the future again.
How to start:
Switch to design mode in BEX Analyzer:
Implement a BEX 7.0 design item u201Cbuttonu201D
Click on the button to implement the properties
Make the input for the commands
data_provider = dataprovider_1
cmd = process_variables
subcmd = var_submit
No comes the part with the variables u2013 Letu2019s assume a query has 4 variables but you only want to change 1 with the button u2013 an organizational unit for instance.
Make a range somewhere in the excel with the following structure:
Name    Index   Value
VAR_NAME_1      1       Variablename
VAR_VALUE_EXT_1 1       variablevalue
Value should contain the name of your variable of course and u201Cvalueu201D the value of your variable
Set a name for this range with EXCEL functionality but without the header:
Back to the properties of the button: Insert the name of the range with the variables in the field Command Range:
If you have more variables to process you can of course enhance your Filterrange!
In the left upper Corner you have a name for your button:
Now you can raise the button-click in vba like this:
Application.Run "'" & ThisWorkbook.Name & "'!Sheet2.BUTTON_35_Click"

To pass new session variable value to stored proc before running a report.

Hi,
Below is summary of the report requirement -
Database level design
1. Created a view and a global temporary table (GTT)
2. Created an Oracle package procedure to accept from and to business dates on basis of which it will fetch, process and populate the GTT.
Repository level design
1. Created a business model containing the view and the GTT (mentioned above)
2. Created two SESSION variables "from_dt" and "to_dt" to be initialized by their respective init blocks. Each of the variable is initialized with a DATE column value (of type DATETIME) from a database lookup table. I have also set the option "Enable that variable to be set by any user" for both variables.
Query for these variables :
from_dt = select from_date from <table>
to_dt = select add_months(from_date,12) from <table>
Presentation level design
1. Using a text box, i display the default/initialized values of these variables like this -
Current business date:@{biServer.variables['NQ_SESSION.from_dt']} Future business dt:@{biServer.variables['NQ_SESSION.to_dt']}
Dates get displayed in YYYY-MM-DD 00:00:00 format
The text msg displays these default dates and allows the user to specift different date range for which i create prompts as shown below.
2. Using any random two columns of date type from the business model, i create two date dashboard prompts with labels "From Dt" and "To Dt".
i select Calender Controls for both; setting Default To = Report Defaults.
The Set Variable is set to Presentation variables - such that pv_from_dt maps to "From Dt" and pv_to_dt maps to "To Dt".
3. i create the report using the business model created above. In the report "Advanced Tab" => "Prefix" field i specify the following -
SET VARIABLE from_dt='@{pv_from_dt}',to_dt='@{pv_to_dt}';
Note : The logic here is to display the default dates and allow user to specify different date values which will be stored in presentation variables.
If the user does specify different "from dt" and "to dt" values, then using the presentation variables, i want to "write" back these new values to the corresponding session variables mentioned above.
If the user does not specify different date range, then the default/initialized dates must be considered.
I also display the default and new date values in the report title.
Back to Repository level design
To execute the stored procedure that will load the GTT before running the report I need to pass two date parameters to the stored procedure on basis of which it will fetch data, process and populate the GTT.
In the Connection Pool --> Connection Script Tab --> Execute before query, I wrote the below query using the repository variables FROM_DT and TO_DT to execute the procedure -
DECLARE
v_from_dt date;
v_to_dt date;
BEGIN
v_from_dt := VALUEOF(From_Dt);
v_to_dt := VALUEOF(To_Dt);
package_name1.package_body(v_from_dt,v_to_dt);
END;
Now when i try to run the report i get the following error :
[nQSError: 10058] A general error has occurred. [nQSError: 23006] The session variable, NQ_SESSION.to_dt, has no value definition. (HY000)..
Need help on this.
Is it possible to "write back" a new value to a session variable ?
Any other alternatives.
Thanks
Nusrat

Sandeep, I found a several topics where users describe saving values in DB through stored procedure or function. For example, [How to store OBIEE presentation level variable values in DB |http://forums.oracle.com/forums/thread.jspa?threadID=892006] I tried it and get an error
*10058. [NQODBC] [SQL_STATE: HY000] [nQSError: 10058] A general error has occurred. [nQSError: 17001] Oracle Error code: 14551, message: ORA-14551: cannot perform a DML operation inside a query ORA-06512*
It's not a BI error. This error are generated by Oracle DB. If I write next:
SELECT MyPLSQLFunction(p1,p2) FROM DUAL
I get the same error.
Oracle doesn't allow DML operations in SELECT.
Did you relalize this feature yourself? Where did I mistake?

How to pass the values to stored proc using presentation variable in OBIEE

Need your help regarding in resolving an issue in OBIEE 10.1.3.4.1
There are 6 reports say ‘A’,’B’,’C’,’D’,’E’,’F’ in the same subject area.
The reports are being configured with prompts using either the repository/presentation variables.
One of the reports say ‘A’ has been configured to pass the values using presentation variables from the prompt in Advanced Tab of the report request to the stored procedure defined in the Execute Before Query section of the connection pool.
After running another report ‘B’ in the same subject area, upon visiting the report ‘A’ view display error is being seen ( Please have a look below screen shot for your reference) .
Speculate the issue is around presentation variables of report ‘A’ getting initialized even before running the report.
Appreciate your earliest advise as this is a prod issue.

Hi Prasad,
I got your note, you should not use Session variable syntax to call presentation variable.
you should use like @{AIC_PROJ_PLAT_SEQ_NO}
One more thing: first test the variable AIC_PROJ_PLAT_SEQ_NO value then try to pass to SP.
Hope this helps

How I set a value to only parameter one of them , such as set
GoodsID when use mx:remoteObject.
Thanks for your help

Got maybe a solution for you, I have just tested it.
So, the idea is to use intermediate variables. Imagine Var1 and Var2 variables that you refresh with your more or less complicated queries. Then what you can do is to refresh your final variable Var3 with a query using your intermediate variables. Here is an example for Oracle:
select #Var1+#Var2 from dual
This way you can make a chain of dependent variables: Var3 is using Var2 and Var2 is using Var1.
Hope it helps.

How to set default values for boolean columns

I'm trying to deploy some content types and columns into a site with a feature. All it's ok, except that I'm trying to set a default value for boolean columns with no success.
I've tried to set default value at column level:
<Field ID="{EFE23A1D-494E-45cf-832E-45E41B17F0CF}" Name="ScopeSpanish" DisplayName="Se publican noticias en español"
Type="Boolean" Hidden="FALSE" Group="Columnas ShaCon" >
<Default>TRUE</Default>
</Field>
and at content type level:
<FieldRef ID="{EFE23A1D-494E-45cf-832E-45E41B17F0CF}" Name="ScopeSpanish" DefaultValue="TRUE" Required="TRUE" />
But in any case, when i create a new item with this content type, default value is applied.
Can anyone tell how to set default values for boolean columns?
Thanks in advance,
Regards,
Sergio

In the field definition you can set
<Default>1</Default>
or
<Default>0</Default>

I have passed employee name "Robert" to cookie in srcpage.jspx,but it prints "JSESSIONID....." instead of "Robert" in destpage.jspx
Thanks in advance
Kalee

Hi,
"cookie" is a reserved name. If you want to write to a session scope attribute called "cookie" then you have to call #{sessionScope.cookie}. If you want to use EL to set and read from cookies then you will have to use
#{cookie.cookieName}
Note that #{cookie} writes to and returns a map

How to Read Variable Values in WAD 7.0 Using JavaScript

Please advice.

How to set the value of something in a component from the main application?

Hi,
Maybe I've been working on this too long, but I can't figure
out how to set the value of the text property of a text input field
in a component from my main application in an mx:Script block. I
have a component called Login in the components folder, and I need
to set the text value of empNum. In my mxml declaration at that the
top, I've declared these components as xmlns:c="components.*" So
logically, the property I'm trying to set is c.Login.empNum.text. I
can't figure out the correct syntax to get this to work, and I've
tried everything I can think of. Does anyone have any suggestions?
I'm thinking this should be an easy one, and I'm just missing
something.
Thanks!
Holli

Did you try giving it an id ?
<c:MyLogin id="loginScreen" /c>
So later you can do loginScreen .empNum.text = "my text"

How to set the value in SelectOneChoice

I need an help....
can anyone please tell me how to set the value in SelectOneChoice.
I want to set the value at index 3
i am trying selectOneChoice1.setvalue(new Integer(3)); but it is throwing an NullPointerException.
Thanks,

Hi,
is it ADF bound? If so then you set the default value to the list binding in the PageDef file. The value of the component must be bound to a method expression, which is why you see an exception. However, I think we need more information

Please help me how to set default values in select-options ( s_hkont ) in INTIALIZATION event

Select option is table <Structure> with fields, low, high, sign & option
you need to append the value into the select option, with appropriate value in low or
example:
S_HKONT-low = <value>
S_HKONT-SIGN = 'I'
S_hkont-OPTION = 'EQ'
append s_hkont.
Default value for select-option also can be added directly in select-option statement.
