Passing a parameter to a function via an alias

Hi all,
Is it possible to pass a fixed value to a function from a alias?
For example say you have a function which opens a web browser and that function accepts a parameter for the URL that you want the browser to load. You can then just call the function and pass the URL across. This will then load the browser with the specified
URL.
What I want to try and do is create an alias called openMS. This alias would call the function and pass the url microsoft.com across. I could then create multiple aliases for opening various pages and use just one function.
I've had a bit of a search but can't seem to find anything so not sure if what I'm trying to do is possible.
Thanks
Peter

You can't do that with an alias, but you can just write another function to accomplish that. The "help" and "mkdir" functions are examples of this technique in the built-in PowerShell commands. "help" pipes Get-Help to more,
and "mkdir" calls New-Item with a hard-coded parameter of -Type Directory . You can see the code for each of those by typing $function:help and $function:mkdir .

Is it necessary to pass RETURN parameter in bapi function module

Hai All,
            Is it necessary to pass structure to RETURN parameter in bapi_transaction_rollback function module. If it is not necessary then how can it gives return value. Please give me the answer for this one. some sample code below...
CALL FUNCTION 'BAPI_TRANSACTION_ROLLBACK'
IMPORTING
   RETURN        = i_return.
        LOOP AT i_return into wa_return WHERE type EQ c_error.
          wa1_out-postdoc = wa_return-message.
        ENDLOOP.
Thanks & Regards.
Laxman.P

hi
bapi should never throw an error as it might be called for mass data proceessing
and it is prefferred not to hault the proceess bcoz of one or two errors.
that's why the error or success messages are caught and returned in return table.
in bapi_transaction_rollback the return parameter is not necessary as it will work without that as well.
the purpose of rollback bapi is just to undo whatever done before that.

How to pass servlet parameter using encodeURL function in JSP page

Hi!!!
I have a very urgently problem.
in my JSP I have this:
<IMG border="0" src='<%=response.encodeURL("/MyImageServlet")%>'>
In this way, my servlet works fine (and I have in my page my blob-image).
But I have to pass to my servlet a list of dynamic parameter. I have tried all the possibilities like:
<IMG border="0" src='<%= (response.encodeURL("/MyImageServlet") + "?Param_name=" + sessionBean.getParamValue() + "&anotherParam" + sessionBean.getAnotherParamValue())%>'
but nothing....
In my servlet I use the init function to retrieve the initial parameters(defined in my web.xml file) in this way:
public void init(ServletConfig config) throws ServletException
super.init(config);
myParam = getInitParameter( "name_of_param");
but I retrieve only the default value (-1).
How to pass to my servlet the parameters? Please help me!
Excuse me for my english,
thank you for your help!

Hi!
Thanks for your reply!
I have tried this solution but it doesn't work!
When I do getInitParameter in the init function, the servlet take the default values...
Maybe I have wrote something wrong?

Passing multiple parameter to SSIS package via data manager

Hi
We are trying to pass parameters from data manager to SSIS package. We are trying to give option of selecting members from Dimension using SelectInput while modifying script.
But we are not able to catch the values in SSIS package.
Code in Data manager package:
(ON)
(SELECTINPUT,%VER%,,"Select Account",%ACCOUNT_DIM%)
(Execute sp_ver_copy,SqlStatementSource,exec dbo.sp_ver_copy2 '%VER%')
We also tried with writing GLOBAL(VER,%VER%) instead of -- (Execute sp_ver_copy,SqlStatementSource,exec dbo.sp_ver_copy2 '%VER%')
But that also dosent work.
We need to use the parameters passed, in SQL code that we have written in OLE DB source, under data flow task.
Any help is appreciated.
Thanks in advance

Thanks Roberto for reply.
Please find the screenprint as per your suggestion. Also I have mentioned the code in above question. We are using the stored procedure to write the value into a table , passed from front end. We are able to write the value passed from front end into a table. So it means that system is passing the value.
But when I try to bring same value into the data task flow , system is throwing a error. The description of error is also mentioned below.
Kindly advise.
Error Description in DM package:
Description = Executing the query "exec dbo.sp_ver_copy2 'Account'" failed with the following error: "An error occurred while extracting the result into a variable of type (DBTYPE_STR)". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.

How to pass input value to the IN parameter in a function

Hi ,
I'm new to pl/sql programming.
The below function is used inside a package and the package is invoked in visual studio.
The function uses 2 input parameters.
Out of which 'in_report_parameter_id' value comes thru job processor service 's job request.
The second IN paramter values are hard coded in the function.
I'm not able to understand this.
If the values are hard coded , how to make sure that only the hard coded values are the right ones?
Please anyone could explain to me?
I really dont have good idea about how to pass INPUT parameter to the functions or procedure
Is there any nice document which could give me good understanding about what are the ways or types we could pass values to the input parameter in subprograms?
thanks in advance.

This is not a design I would use, but should work if coded properly. I would probably build a reference cursor query as text and use one open fetch and close.
You have 2 input parameters, in_report_parameter_id and in_which. I could not find where in_report_parameter_id was used in the program, but the value passed in for in_which is being used in IF logic to decide how to open the cursor. After the cursor is open rows are being fetched and eventually the cursor is closed.
The values in_which are compared to are hard-coded. It is the programmer's job to make sure the values listed are the right values and the actions taken are also correct. Your program is assuming that if the first 2 values are not encountered the third one listed is the one you want.
To pass input values to a procedure you merely provide the values as a literal or variable in the call, something like
whatever := get_class_text_str(1,'SELECT');

Pass a Parameter to Function?

Hi All,
can you please tell me is it possible to pass a parameter to a function in the Select statement
for example
select * from table(test.get_trans_by_period('141', '123456874', '20000101', '20100101'))
How can I use BI Publisher to pass the values using parameters
I tried
select * from table(test.get_trans_by_period(:p_param1, :p_param2, :p_param3, :p_param4))
but it's not working
BR,

You can write a data template, and call the function from within the xml block for the data template, as in a database query.
The rtf supports xsl code behind the tags, so can write xsl code in rtf.

Adding more to what 'Arcturus' has put across :
1) You can check your input & output arguments to a PL/SQL function/procedure using an assign activity, in which you tend to assign a source variable to a target variable.
Here, you can check to see, if the input & output to the DB Adapter are correct, if not, you can always recreate the adapter.
2) You can also check the schema of the PL/SQL function, to check if it has the right inputs & outputs.
It'd be a .xsd file in the format of <SCHEMA_NAME-OF-FUNCTION.xsd> viz. SCOTT_EMPDETAILS.xsd

How to pass dynamic parameter to a database function in OBIEE

Hi,
I have a requirement like this. I have to create one report in OBIEE which was in Discoverer. Now in discoverer report there are some calculated item in the worksheet based on database pkg.functions. The parameter which user gives at run time that parameters are then passed to the discoverer calculated items dynamically. But I am not able to do this in OBIEE answers.
Can anyone tell me step by step how I can able to pass the user selected parameter values in OBIEE answer level.
The example:
GET_COMM_VALUE_PTD("AFE Cost & Commitment".Afe Id,:"Period Name(AFE)","AFE Cost & Commitment".Data Sel,"AFE Cost & Commitment".Org Id)
GET_COMM_VALUE_PTD --- Function database
("AFE Cost & Commitment".Afe Id,:"Period Name(AFE)","AFE Cost & Commitment".Data Sel,"AFE Cost & Commitment".Org Id --- Parameters... :"Period Name(AFE)" is the dynamic parameter selected run time by user.
Please help.
Thanks

Hi,
I already did that. But the existing discoverer re value report is showing correct value but the OBIEE report with EVALUATE function shows incorrect value.
The requirement is to create a OBIEE Dashboard from a Discoverer existing report. Now in discoverer report theere are several calculated items in worksheet level where database custom function is used and user selected parameter value is passed run time in that function. But when that is created in OBIEE with EVALUATE function in RPD, the report shows incorrect data. Could not understand how to pass the parameter value runtime.
Below is the discoverer 'Show SQL' query and EVALUATE function syntax which has been used.
SELECT APPS.XXBG_PL_PROJ_ANALYSIS_AFE_PKG.GET_COMM_VALUE_PTD(XXBG_PL_PROJ_AFE_V.AFE_ID,
:"Period Name(AFE)",
XXBG_PL_PROJ_AFE_V.DATA_SEL,

AND (PA_PERIODS_ALL.PERIOD_NAME = :"Period Name(AFE)")
AND (XXBG_PL_PROJ_AFE_V.AFE_NUMBER = :"AFE Number(AFE)")
AND (XXBG_PL_PROJ_AFE_V.OPERATING_UNIT = :"Operating Unit(AFE)")
The EVALUATE function syntax is as below:
EVALUATE('XXBG_PL_PROJ_ANALYSIS_AFE_PKG.GET_COMM_VALUE_PTD(%1,%2,%3,%4)' AS FLOAT , "BG PL Project Analysis Report_1"."AFE Cost & Commitment"."AFE Cost & Commitment.Afe Id", "BG PL Project Analysis Report_1"."Periods 1"."Periods 1.Period Name", "BG PL Project Analysis Report_1"."AFE Cost & Commitment"."AFE Cost & Commitment.Data Sel", "BG PL Project Analysis Report_1"."AFE Cost & Commitment"."AFE Cost & Commitment.Org Id")
The PERIOD needs to be passed at run time which user will select.
Please help to solve the issue.

Pass multiple values as single input parameter into pipelined function

Hi all,
My need is to pass multiple values as single input parameter into pipelined function.
For example - "2" and "3" are values of input parameter "t":

select 3 as t from dual union all
select 4 as t from dual union all
select 5 as t from dual
select * from data where t in (2,3)Is it possible at all?

Not exactly sure, but usually 'multiple values'+'pipelined function' = some IN-LIST related approach?
See:

How to pass parameter into extract function (for XMLTYPE)

I have a table PROBLEMXML with XMLTYPE field xml_column. In this column there are several deffinitions for the problem. There is no max amount of deffinitions and it can be no definition at all. I need to return all definitions for every problem as a string wirh definitions separated by ";".

The ref cursor interface in PL/SQL only support a static/fixed number of bind variables. So if you want to create cursors with variable number of bind values, you need to use conditional processing. E.g.

SQL>And this approach is for external clients - where a Visual Basic or Java client program calls the database, executes the stored procedure, and receives a cursor handle in turn. And the client then fetches the output of this cursor and process it.
There is no need to return a record type of any sorts. The client wants the cursor handle as that is the optimal and best interface for the client to receive database data.
If the caller is not an external client, but another PL/SQL procedure, then this approach does not make much sense.
It is important that you understand basic Oracle concepts and fundamentals. What a cursor is. What the best way is to process Oracle data. How to best use the basic features of Oracle. Without that basic understanding, you as good as a low hour Cessna pilot getting into an Airbus A400M - where the Cessna pilot would not even be able to start a single engine, never mind get the plane in the air.
Likewise, without a basic understanding of Oracle cursors and fundamentals, you will be unable to code even a single line of sensible code. Not because you are a bad programmer. Even the best programmer in the world will be unable to write decent code, if the programmer has no idea how the environment works, what the concepts and fundamentals are. But it is fair to expect that a good programmer will no write such code, understand that there is a lack of knowledge, and address that accordingly.
