Can rs.last() be used after calling the stored procedure?

Can rs.last() be used after calling the stored procedure? If yes what should be the CURSOR types?

Can rs.last() be used after calling the stored
procedure? If yes what should be the CURSOR types?That would depend on the driver/database.
And as I said in your other post it is far more efficient to count records by just returning a count rather than a complete collection regardless of how you get to the end.

Errors in calling Oracle stored procedure using java CallableStatement

Hello,
I have an oracle stored procedure below, it has been tested in PL/SQL without errors. During testing, in_c_file_type="F"; out_n_seqno_freeformat=120139596 and out_n_seqno_commaseprated is null (empty in value column).

Stored procedure is working properly on sql*plus(Oracle 8.1.5)) editor. But it is not working from a standalone java application. Can anyone please give me a solution.
thanks and regards
Shyam Krishna

The first solution is to not do that in java in the first place.
DDL should be in script files which are applied to oracle outside of java.
Other than I believe there are some existing stored procedures in Oracle that take DDL strings and process them. Your user has to have permission of course. You can track them down via the documentation.

Calling a Stored Procedure with Parameter using an UDF

Hi All,
I have a requirement where I need to use database lookup. In that I am calling the Stored Procedure using UDF. For example sp_flow ., for this I have to pass<INTID> and <USDERID> to get the response.
I am using the below code to excute this.
Channel channel = null;
Map rowMap = null;
DataBaseAccessor accessor = null;
DataBaseResult resultSet = null;
String Query = null;
//Query ="EXECUTE dbo.sp_flow <INTID> <USERID>;
Query = "EXECUTE dbo.sp_flow \'304\' , \'shankar\' " ;
try{
//Determine a channel, as created in the Configuration
channel =
LookupService.getChanne"BS_XXX","CC_XXX_JDBC_Rcv");
//Get a system accessor for the channel. As the call is being made to an
DB, an DatabaseAccessor is obtained.
accessor = LookupService.getDataBaseAccessor(channel);
//Execute Query and get the values in resultset
resultSet = accessor.execute(Query);
for(Iterator rows = resultSet.getRows();rows.hasNext();){
rowMap = (Map)rows.next();
result.addValue((String)rowMap.get("FLOW_ID"));
I am getting the error "Error when calling an adapter by using the communication channel CC_NWLS_TLA_JDBC_Rcv (Party: , Service: BS_MICROSOFT_SQLWLS20DEV_D, Object ID: d30aace599de3cd69548bf145d0724b7) XI AF API call failed.

first of all calling a SP via the lookup API, there is a workaround but it is not at all recommended
FYI
/people/arpil.gupta/blog/2008/11/03/workaround-for-jdbc-scenarios - DB Lookup via Stored procedure
http://help.sap.com/javadocs/NW04S/current/pi/com/sap/aii/mapping/lookup/DataBaseAccessor.html
The accessor does not support transactional behaviour. Therefore, the method should not be used to execute insert or update statements on the database which can lead to inconsistencies. The accessor should only be used to read data from a database table.

Calling a stored procedure using Oracle Ole Db provider

I am looking for an example of syntax used to call a stored procedure from VB.Net using the Oracle OleDB provider. I have been using the Microsoft provider MSDAORA but need to move to the Oracle provider due to upgrade. The syntax used with the MSDAORA provider does not work with the Oracle provider.

Hi,
Please refer to the Populate DataSet with Multiple REF Cursors Sample available at the following URL:
http://otn.oracle.com/sample_code/tech/windows/ole_db/oledb92/index.html
Check the PopulateProducts method available in the ViewProducts.cs file that call a database stored procedure "getProductsInfo" . This code is written in C# you may want to convert it to VB.NET syntax.

How to call a stored procedure using its package name in Oracle

hi
we're doing a JDBC scenario where we call a stored procedure(a.prc) using its package name(b)The stored procedure has In /Out/IN-OUT parameter.
i have got 2 queries:
1- How to call the stored procedure using it's package.
2- How to capture the In/Out parameter in the response.

hi Prateek
thanks for the reply.
However when i tried mapping it to Package.procedure, communication channel throws the error saying that Package.proceudre needs to be declared.
As i said , the procedure has IN-OUT parameter too.In oracle we need to write a block if we want to read the IN-OUT parameter.
How to get the IN-OUT parameter in XI?

Ssrs 2008 r2 report dataset call a stored procedure

I am modifying an existing SSRS 2008 r2 report. In a dataset that already exists within the ssrs 2008 r2 report I need execute
a stored procedure called StudentData and pass 3 parameter values to the stored procedure. The stored procedure will then return 5 values that are now needed for the modified ssrs report. My problem is I do not know how to have the dataset call the stored procedure
with the 3 parameter values and pass back the 5 different unique data values that I am looking for.
The basic dataset is the following:
SELECT SchoolNumber,
        SchoolName,
        StudentNumber,
from [Trans].[dbo].[Student]
order by SchoolNumber,
          SchoolName,
          StudentNumber
I basically want to pass the 3 parameters of SchoolNumber, SchoolName, and StudentNumber to the
stored procedure called StudentData from the data I obtain from the [Trans].[dbo].[Student]. The 3 parameter values will be obtained from the sql listed above.
The columns that I need from the stored procedure called StudentData will return the following data columns
that I need for the report: StudnentName, StudentAddress, Studentbirthdate, StudentPhoneNumber, GuardianName.
Thus can you show me how to setup the sql to meet this requirement I have?

Hi wendy,
After testing the issue in my local environment, we can refer to the following steps to achieve your requirement:
Create three multiple parameters named SchoolNumber, SchoolName and StudentNumber in the report. Those available values from the basic dataset SchoolNumber, SchoolName and StudentNumber fields.
If you want to pass multiple values parameter to stored procedure, we should create a function as below to the database:
CREATE FUNCTION SplitParameterValues (@InputString NVARCHAR(max), @SplitChar VARCHAR(5))
RETURNS @ValuesList TABLE
param NVARCHAR(255)
AS
BEGIN
DECLARE @ListValue NVARCHAR(max)
SET @InputString = @InputString + @SplitChar
WHILE @InputString!= @SplitChar
BEGIN
SELECT @ListValue = SUBSTRING(@InputString , 1, (CHARINDEX(@SplitChar, @InputString)-1))
IF (CHARINDEX(@SplitChar, @InputString) + len(@SplitChar))>(LEN(@InputString))
BEGIN
SET @InputString=@SplitChar
END
ELSE
BEGIN
SELECT @InputString = SUBSTRING(@InputString, (CHARINDEX(@SplitChar, @InputString) + len(@SplitChar)) , LEN(@InputString)-(CHARINDEX(@SplitChar, @InputString)+ len(@SplitChar)-1) )
END
INSERT INTO @ValuesList VALUES( @ListValue)
END
RETURN
END
Use the query below to create a stored procedure, then use it to create a dataset to return 5 values:
create proc proc_test(@SchoolNumber nvarchar(50),@SchoolName nvarchar(50),@StudentNumber nvarchar(50))
as
begin
select StudnentName, StudentAddress, Studentbirthdate, StudentPhoneNumber, GuardianName
from table7 where SchoolNumber in (SELECT * FROM SplitParameterValues (@SchoolNumber,',')) and SchoolName in(SELECT * FROM SplitParameterValues (@SchoolName,',')) and StudentNumber in (SELECT * FROM SplitParameterValues (@StudentNumber,','))
end
Right-click the new dataset to modify the parameter value in the Parameters pane as below:
=join(Parameters!SchoolNumber.Value,",")
=join(Parameters!SchoolName.Value,",")
=join(Parameters!StudentNumber.Value,",")

Sender JDBC support the stored procedure in SQL Server 2005

Dear All,
My question here is , Sender is JDBC adpter support to call the Stored procedure in Microsoft SQL Server 2005?
I followed the below thread before posting this question
Sender JDBC Adapter Supports Stored Procedures????
In the thread Suraj response has mentioned SAP note: 941317, I checked the note, Note says it supported only ORACLE DBMS versions.
Could you please clarify about this to possibility to call the stored procedure in Microsoft SQL server 2005?
Thank you in Advance
Sateesh

Hi Sateesh,
To answer your query, Yes it does. SP call works with SQL Server 2005 as well, the SP call should be "execute SPNAME <paramas>". In the place of update statement put any junk value as mentioned in the earlier comment.
But just one thing to be noted, the select or any other query returning the desired resultset must be the first statement in youre SP returning value to the calling app. Means if there are any update, deletion or intermediate select queries to be used with in your SP, those all should be placed after the Main Select query that returns the desired resultset. Variable declarions and assignments are allowed.
But if the seq of statements in your SP are like:
@var1 Varchar
Update <tablename>....
Select * from <tablename>
Then the output of the SP is :
1 row updated
<the resultset from select>
In such cases, PI can recognise the first value returned only, that is "1 row updated" and hence the returned resultset wouldn't be seen by PI or not be passed to integration engine. Hence the update should come after the main Select.
One more interesting piece of information, even if you copy and paste the entire SP code in place of the query string of Sender JDBC adapter, that too will work with all your variable declarations, multiple queries and updates and everything. Just have to follow the above rule.
Let us know what you find.

Calling a stored procedure with default parameters

Dear all,
I am trying to call a stored procedure that has not all the parameters compulsory, and indeed, there are some I am not interested in. Therefore, I would like to call the stored procedure initializing only some of the parameters but if I miss some of them, I have an SQLException thrown. Is there any way to do that?
Thanks
Marie

Hi
One way to do it is ---
By using Default Parameters you can miss few parameters while calling a procedure.
=================================================================
As the example below shows, you can initialize IN parameters to default values. That way, you can pass different numbers of actual parameters to a subprogram, accepting or overriding the default values as you please.
Moreover, you can add new formal parameters without having to change every call to the subprogram.
PROCEDURE create_dept (
new_dname VARCHAR2 DEFAULT 'TEMP',
new_loc VARCHAR2 DEFAULT 'TEMP') IS
BEGIN
INSERT INTO dept
VALUES (deptno_seq.NEXTVAL, new_dname, new_loc);
END;
If an actual parameter is not passed, the default value of its corresponding formal parameter is used.
Consider the following calls to create_dept:
create_dept;
create_dept('MARKETING');
create_dept('MARKETING', 'NEW YORK');
The first call passes no actual parameters, so both default values are used.
The second call passes one actual parameter, so the default value for new_loc is used.
The third call passes two actual parameters, so neither default value is used.
Usually, you can use positional notation to override the default values of formal parameters.
However, you cannot skip a formal parameter by leaving out its actual parameter.
For example, the following call incorrectly associates the actual parameter 'NEW YORK' with the formal parameter new_dname:
create_dept('NEW YORK'); -- incorrect
You cannot solve the problem by leaving a placeholder for the actual parameter.
For example, the following call is illegal:
create_dept(, 'NEW YORK'); -- illegal
In such cases, you must use named notation, as follows:
create_dept(new_loc => 'NEW YORK');
===============================================================

Calling Oracle Stored Procedure from BC4J JSP App

I am on an extremely tight deadline and am trying to get my JSP application to use an Oracle Stored Procedure. I need to take some input from the user and send these values as parameters. Has anyone worked with Stored Procedures in JDev3.1? Please reply with some sample code if possible.
Thanks.

Hi,
Someone posted a similar request the other day. Here is my response to them:
Basically, you need to create a custom method from your JSP's ViewObject, which calls the stored procedure. You can then call the ViewObject's custom method from the JSP client.
Here is how I have done it:
1. Choose the ViewObject that your JSP is based on and choose 'Edit' from the context menu.
2. On the Java tab of the ViewObject wizard, choose Generate Java File checkbox for the View Object Class and click the Finish button. A file is created under the ViewObject node in the Navigator named 'viewobjectImpl.java'.
3. Open the viewobjectImpl.java file in the code editor and create a method to call your stored procedure (see sample code below).
4. Compile the VOImpl.java file.
5. Choose the view object again, and choose Edit again from the context menu.
6. On the Client Methods tab, you should now see your method appear in the Available field. Select it and shuttle it to the Selected field.
7. Click Finish to leave the VO wizard, and rebuild your Business Components project.
8. In your JSP, call the custom method (see sample code below).
sample code for custom method calling a stored procedure from VOImpl.java file:
public int getTotalHits(String mon, String year) {
CallableStatement stmt = null;
int total;
// the call to the PL/SQL stored proc
String totalhits = "{? = call walkthru.total_hits(?,?)}";
// use the AM conxn 2 call storedproc
stmt = getDBTransaction().createCallableStatement(totalhits, 1);
try
// Bind the Statement Parameters and //Execute this Statement
stmt.registerOutParameter(1,Types.INTEGER);
stmt.setString(2,mon); stmt.setString(3,year);
stmt.execute();
total = stmt.getInt(1);
catch (Exception ex)
throw new oracle.jbo.JboException(ex);
finally

Use database inside a stored procedure

Hi guys, a stupid question: I'm working with several database and sometimes I'm afraid to run an alter or a create something in the wrong database, bear in mind that several database have the same tables. Sometime happens to run a query oin the db A
instead in the db B. So, the question: If I create a procedure like this,
create procedure creatingPillar as
use USA
begin
IF EXISTS (SELECT * FROM sys.objects WHERE object_id =
OBJECT_ID(N'pillarretail') AND type in (N'U'))
DROP TABLE PillarRetail
create table PillarRetail (anid int , ancore varchar(20), period dec(18,6), settlem datetime2,
settlementper int, asf dec(18,6),astlf dec (18,6), tot dec (18,6) )
insert into PillarRetail select anid, ancore, Period, settlem, settlementper,
asf, astlf, tot from createsemipillar2011
insert into PillarRetail select select anid, ancore, Period, settlem, settlementper,
asf, astlf, tot createsemipillar
end
but I'm wondering if is useless to put the use USA in the stored procedure by the moment that I'm creating the procedure in USA. I mean, having the SP in the USA db even if I run the procedure from another db it should run in USA. Just a stupid question
I know but I got this doubt...
Thanks

You may try as below:
create proc as below: (This will create the proc in USA database.
use USA
Go
create procedure dbo.creatingPillar as
begin
IF EXISTS (SELECT * FROM sys.objects WHERE object_id =
OBJECT_ID(N'pillarretail') AND type in (N'U'))
DROP TABLE PillarRetail
create table PillarRetail (anid int , ancore varchar(20), period dec(18,6), settlem datetime2,
settlementper int, asf dec(18,6),astlf dec (18,6), tot dec (18,6) )
insert into PillarRetail select anid, ancore, Period, settlem, settlementper,
asf, astlf, tot from createsemipillar2011
insert into PillarRetail select select anid, ancore, Period, settlem, settlementper,
asf, astlf, tot createsemipillar
end
Then you can call as below:
Exec USA.dbo.creatingPillar

Can rs.last() be used after calling the stored procedure?
