Wrapped in a function and/or stored procedure, recursive CTE stops working

This query builds an hierarchical tree from a single table with the typical
value/reports_to_value columns.
When running in SQL manager returns like 7 records (note i'm avoiding infinite
loop by blocking top level value)
WITH c
AS
SELECT deptid, reports_to_dept
FROM glo_tree
WHERE deptid = '18538'
UNION ALL
SELECT t.deptid, t.reports_to_dept
FROM glo_tree T
INNER JOIN c
ON t.deptid = c.reports_to_dept
where t.deptid <> '00001'
SELECT deptid
FROM c
However, the exact same query, if wrapped in a function and/or stored procedure,
returns 0 records (no error message whatsoever)
CREATE FUNCTION [dbo].[checkDept] (@deptid varchar(16))
RETURNS TABLE
AS
RETURN
WITH c
AS
SELECT deptid, reports_to_dept
FROM glo_tree
WHERE deptid = @deptid
UNION ALL
SELECT t.deptid, t.reports_to_dept
FROM glo_tree T
INNER JOIN c
ON t.deptid = c.reports_to_dept
SELECT deptid
FROM c
GO
CREATE PROCEDURE [dbo].[getDept] (@deptid varchar(16))
AS
SELECT deptid
FROM dbo.checkDept(@deptid)
Then call them like:
select * FROM checkDept('18538')exec getDept @deptid='18538'
Both return nothing

Thanks Patrick, i don't think it can do that, i call it like:
select * FROM checkDept('18538')exec getDept @deptid='18538'Just to make sure, i've changed the function like:WHERE ltrim(rtrim(deptid)) = @deptidStill the same thing

How to convert REFCursor functions to REFCursor Stored Procedure

Is it possible or not.How to want convert REFCursor functions to REFCursor Stored Procedure.For Example
function QR_1RefCurDS return pkg_sa_reprts_ref_cursr.pa_mis_sa_disp_cursr is
data_cursr pkg_sa_reprts_ref_cursr.pa_mis_sa_disp_cursr;
begin
data_cursr:= sf_sa_dispatch_reprt(:P_USER,:P_USER_TYPE,:P_AREA_CD,:P_RPT_LEVEL,:P_PARNT_GROP,:P_LOCTN_CD,:P_DATE);
return data_cursr;
end;
how to convert it.

Its possible. But you need to analyse the requirement well. Post conevrsion, you need to take care of places in the code where the function call is made to invoke the new procedure.
create procedure QR_1RefCurDS_pr (out pkg_sa_reprts_ref_cursr.pa_mis_sa_disp_cursr) is
data_cursr pkg_sa_reprts_ref_cursr.pa_mis_sa_disp_cursr;
begin
data_cursr:= sf_sa_dispatch_reprt(:P_USER,:P_USER_TYPE,:P_AREA_CD,:P_RPT_LEVEL,:P_PARNT_GROP,:P_LOCTN_CD,:P_DATE);
end;

Call a Vbscript from a stored procedure

Hi,
I wonder is it possible to call a Vbscript from a stored procedure, any good reference for this.
thanks

Well here is quick and dirty example I just created.
Step 1. Create a test_batch.bat file that creates a folder "c:\test_dir" and copy "c:emp.lst" into it.
C:\oracle102\examples\test_batch.bat
md c:\test_dir
copy c:\emp.lst c:\test_dir
Step2. From SQLPLUS, spool scott.emp into c:\emp.lst and call the batch from the dbms_scheduler that kicks off right away,
set echo off
set feedback off
spool c:\emp.lst;
select * from scott.emp;
spool off;
begin
     dbms_scheduler.create_job(job_name => 'run_batch',
     job_type => 'EXECUTABLE',
     job_action => 'C:\oracle102\examples\test_batch.bat',
     start_date => sysdate,
     enabled => true,
     comments => 'Run VB Script');
end;
Check if the directory is created and if the file is copied over. Task is to kick off the executable and test is the VBscript within the batch. Challenge is how long the script runs before the next statement in the PL/SQL runs. May be you have to introduce sleep in between.
Note: You must have at least "CREATE JOB" privilege.
Happy coding!

Calling JPA from a Java Stored Procedure

Is it possible to call JPA from a java stored procedure? If so, does anyone have example? How do you setup the persistence.xml?
How does the peformance compare with straight JDBC in a java stored procedure?
Thanks for any help!
Johnny

Hi Johnny:
Basically you can run any JDK 1.5 framework inside your Oracle 11g JVM, I have experience integrating Lucene IR library as a new [Domain Index for Oracle 11g/10g|http://docs.google.com/View?id=ddgw7sjp_54fgj9kg] .
I am not familiar with JPA internals but my advice is howto handle the connection inside the OJVM and the configuration files.
Some time ago I took a look to SpringFramework integration and I found that writing a new ApplicationContext class which handles the loading of beans.xml from XMLDB repository instead a file should be enough to work.
Another important point is the life cycle of the [Oracle internal JVM|http://download.oracle.com/docs/cd/E11882_01/java.112/e10588/chtwo.htm#BABHGJFI]. Unlike an standard JVM the OJVM is created once you first connect from the middle tier at OCI level and remains in execution during the connection pool existence.
I mean, if you connect using a JDBC pool the JVM will remains running across multiple soft open/close connections of your middle tier application. This is good because you can read your persistence.xml file using a Singleton class and this expensive operation will be re-used by multiple open/close operation done from the middle tier.
I suggest you do a simple Proof of Concept with a Hello World application and check if it works.
Remember that any security issues will be notified to the .trc files, security issues are related to the strong security layer configured by default inside the OJVM, for example you can not read any files from the OS file system without an specific grant, you need another grant to access to the class loader and so on, but you can simply grant this specific needs to a database role and then grant this role to the user which connect to the OJVM.
Another important point is related to the [End-of-Call Optimization|http://download.oracle.com/docs/cd/E11882_01/java.112/e10588/chtwo.htm#BABIFAAI] this can be useful if you want to perform some clean up in your Singleton class at the level of per-statement execution.
Best regards, Marcelo

How to execute a procedure or function from Java Stored procedure

Hi,
I am new to Java Stored Procedures. I am working on Oracle 8i and JVM 1.3.1. I want to call a PL/SQL procedure from within Java. I have tried looking at severa; cources but they are quite high level for me. Can someone provide a simple example including the Source Code for .java file and also the calling function's code?
Heres a sample of what I have been working on: I an including Java code, and Function code and how I call the function. Instead of doing "select sysdate from dual" I want to do like "create table temp1(var1 varchar2(10))" or similar... like "exec procname(var1)" etc.
Thanks in advance.
PS. The variable passed in function is just a dummy variable.
-----Begin Java code-------
import java.sql.SQLException;
import java.sql.PreparedStatement;

//Oracle Extensions to JDBC
import oracle.jdbc.driver.OracleDriver;
public class Test2{
public static String Testing(String d) {
Connection connection = null; // Database connection object
try {
// Get a Default Database Connection using Server Side JDBC Driver.

what your after is
Connection conn = DriverManager.getConnection
("jdbc:oracle:oci:@<hoststring>", "scott", "tiger");
CallableStatement cs = conn.prepareCall ("begin ? := foo(?); end;");
cs.registerOutParameter(1,Types.CHAR);
cs.setString(2, "aa");
cs.executeUpdate();

Calling Java programs from Oracle Stored Procedure

Is it possible to call Java programs from Oracle stored procs? If possible Can this be used to exchange data from other applications? Is there a better method/feature in oracle for doing data exchange with other apps?

If what you mean by Oracle stored procedures is pl/sql then yes.
You can create a "wrapper" this way:
CREATE OR REPLACE FUNCTION xmlXform
in_mapUrl IN VARCHAR2,
in_inputUrl IN VARCHAR2
RETURN VARCHAR2
AS
LANGUAGE JAVA NAME
'com.yourcompany.xml2any.xform(java.lang.String,java.lang.String)
RETURN java.lang.String';
Then load the java as:
loadjava -user youruser/youruserpasswd -resolve -verbose lib/xmlparserv2.jar classes/com/yourcompany/xform.class classes/com/yourcompany/xml2any.class
The java, given the correct permissions, can do anything java can do including communicate with outside applications.
Is this the "best" way... depends on what you are trying to accomplish.

Calling a report from a Stored Procedure

Is it possible to call a Oracle Report from a Stored Procedure or a Packaged Stored Procedure. If Yes, please provide some details.
Thanks
Shalu

Shalu,
there's an API available to do this.The feature is called "event driven publishing" (because you can use this even from a trigger) and you can find the documentation here:

Getting error code 1 when calling SSIS package from a stored procedure (SQL Server 2008 R2)

Hello,
I am trying to execute a SSIS package from SQL Server 2008 R2 stored procedure but getting error code 1 (as per my knowledge, error code description is as below:
0 The package executed successfully.
1 The package failed.
3 The package was canceled by the user.
4 The utility was unable to locate the requested package. The package could not be found.
5 The utility was unable to load the requested package. The package could not be loaded.
6 The utility encountered an internal error of syntactic or semantic errors in the command line.
Details:
I have a stored procedure named "Execute_SSIS_Package" (see below sp) which executes 'Import_EMS_Response' SSIS package (when I execute this package directly from SQL Server BID it works fine it means package itself is correct) and calling
it from SQL as:- EXEC Execute_SSIS_Package 'Import_EMS_Response'.
Here I receives error code 1.
Can anyone help me to resolve this issue please?
Thanks in advance!
CREATE PROCEDURE [dbo].[Execute_SSIS_Package]
@strPackage nvarchar(100)
AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON;
DECLARE @cmd VARCHAR(8000)
DECLARE @Result int
DECLARE @Environment VARCHAR(100)
SELECT @Environment = Waarde
FROM Sys_Settings
WHERE Optie = 'Omgeving'
--print @Environment
SET @strPackage = '"\W2250_NGSQLSERVER\BVT\' + @Environment + '\' + @strPackage + '"'
SET @cmd = 'dtexec /SQL ' + @strPackage + ' /SERVER "w2250\NGSQLSERVER" /Decrypt "BVT_SSIS" /CHECKPOINTING OFF /REPORTING E'
--print @cmd
EXECUTE @Result = master..xp_cmdshell @cmd, NO_OUTPUT
--print @Result
END

It has something to do with the security.
E.g. cmdshell is not enabled or the caller has not rights over the package.
There could be a syntax error, too.
I suggest you make the package runnable off a SQL Agent job then trigger the job from the stored proc with
sp_start_job <job name>

Using writetext function in a stored procedure for Sybase 11.5

Hello,
I need to execute the writetext function inside a Sybase stored procedure to insert varchar data of approximately 4k size.
how to specify data parameter in writetext fot that?

The split function Scott used is some variant on one of the solutions posted in the Ask Tom link I posted. More specifically, it is probably a variant on either one of the pipelined function solutions, or one based on splitting the string into a SQL table of objects.
Look at Tom's original response to the question for a working solution. If you have a reasonably new version of Oracle, then you may also want to look at the modificataion/modernization later in the thread which can be found here
