Stored procedure call not working
I have 2 ms-sql update statement through stored procedures
1) as a batch update
if (vendorBillDetailsDTO != null) {
stmnt =
con.prepareCall(
"Exec usp_CMP_UpdPRDetails ?, ?, ?, ?");
Iterator it = vendorBillDetailsDTO.iterator();
while (it.hasNext()) {
VendorBillDetailsDTO myVendorBillBillDetailsDTO =
(VendorBillDetailsDTO) it.next();
stmnt.setInt(
1,
myVendorBillBillDetailsDTO.getBillDetailRef().intValue());
stmnt.setInt(
2,
myVendorBillBillDetailsDTO.getBillId().intValue());
stmnt.setString(3, myVendorBillBillDetailsDTO.getCRN());
stmnt.setInt(
4,
myVendorBillBillDetailsDTO.getServiceCode().intValue());
stmnt.setString(5, myVendorBillBillDetailsDTO.getPRShortText());
stmnt.addBatch();
//it.next();
} //while
stmnt.executeBatch();
} //if
This block is working perfectly fine and statement is correctly getting executed
2) if (vendorBillHeaderDTO != null) {
stmnt = con.prepareCall(
"Exec usp_CMP_UpdPRHeader ?,?,?");
stmnt.setInt(1, vendorBillHeaderDTO.getBillId().intValue());
stmnt.setString(2, vendorBillHeaderDTO.getBillType());
stmnt.setString(3, vendorBillHeaderDTO.getEstimateReference());
stmnt.executeUpdate();
}//end if
This statement is not getting executed (I have many input parameters like int , timestamp , long , double etc). It is not throwing any error (Even when I enclosed it with try catch theere is no exception thrown .) However in back end record is not getting updated .
Any ideas ?
Please help
NPB
Well, that could be a problem in the Data Base side, i suggest you:
1) See the log file of your DB,
2) Run in your DB the Store Procedure, maybe you forget put a commit, and see that of this way you can update the table you can.
Try it.
Regards if helps you

Stored procedure does not work!
okay, this is one of the weirdest things i have ever seen...so i have created a registration page to my code which on submit it will fire the following codes
protected void btsSubmit_Click(object sender, EventArgs e)
if (tbxFName.Text.Trim().Length == 0 || tbxLName.Text.Trim().Length == 0 || tbxUsername.Text.Trim().Length == 0 || tbxPassword.Text.Length == 0)
ScriptManager.RegisterStartupScript(this, this.GetType(), "myscript", "ShowNotification('Warning','Please fill the required textboxes');", true);
else
try
string conString = ConfigurationManager.ConnectionStrings["IRELDBCS"].ConnectionString;
using (SqlConnection con = new SqlConnection(conString))
SqlCommand sc = new SqlCommand("spUserRegister", con);
sc.CommandType = CommandType.StoredProcedure;
sc.Parameters.AddWithValue("@a", tbxFName.Text.Trim());
sc.Parameters.AddWithValue("@b", tbxLName.Text.Trim());
sc.Parameters.AddWithValue("@c", tbxUsername.Text.Trim());
sc.Parameters.AddWithValue("@d", tbxPassword.Text);
sc.Parameters.AddWithValue("@e", ddlUserType.SelectedValue);
con.Open();
int ReturnCode = (int)sc.ExecuteScalar();
if (ReturnCode == -1)
ScriptManager.RegisterStartupScript(this, this.GetType(), "myscript", "ShowNotification('Error','This user is already exists.');", true);
else
ScriptManager.RegisterStartupScript(this, this.GetType(), "myscript", "ShowNotification('Success','you registration was successful');", true);
catch
ScriptManager.RegisterStartupScript(this, this.GetType(), "myscript", "ShowNotification('Error','Something went wrong, please try again in a few minutes');", true);
i was using sc.ExecuteNonQuery(); instead of int ReturnCode = (int)sc.ExecuteScalar();
and it was working fine and it was functioning till i have added the part which it stops user from registering with the same email address which is
int ReturnCode = (int)sc.ExecuteScalar();
if (ReturnCode == -1)
ScriptManager.RegisterStartupScript(this, this.GetType(), "myscript", "ShowNotification('Error','This user is already exists.');", true);
else
ScriptManager.RegisterStartupScript(this, this.GetType(), "myscript", "ShowNotification('Success','you registration was successful');", true);
and this is my stored procedure
USE [dbo.IrELearn]
GO
/****** Object: StoredProcedure [dbo].[spUserRegister] Script Date: 04/01/2014 19:35:08 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON

@e smallint
as
BEGIN
declare @Count int
declare @ReturnCode int
SELECT @Count = COUNT(Username)
FROM tbl_Users WHERE Username = @C
IF @Count > 0
Begin
Set @ReturnCode = -1
End
Else
Begin
Set @ReturnCode = 1
INSERT INTO tbl_Users (FirstName, LastName, Username, Password, UserType) VALUES (@a,@b,@a,@b,@e)
End
SELECT @ReturnCode as ReturnValue
END
now users cant register anymore and when i tried to debug and find where the problem is, it completely skips the "if" section after
int ReturnCode = (int)sc.ExecuteScalar();
im not sure whats goin on!! can anyone find out what the problem is?
thank you in advanceCan you try to replace the statement in the Stored Proc
SELECT @ReturnCode as ReturnValue
with
RETURN @ReturnCode
The SELECT statement returns the value as a dataset but the RETURN statement returns it as a Return Code for success/failure of the Stored Proc execution.
Normally RETURN(0) i.e. a zero is returned as a default for success and a non-zero value is returned for a failure. But don't obther about the values at this time, just try the RETURN statement.

The link to a user defined oracle stored procedure does not work
This is based on the HowTo Download a file
http://otn.oracle.com/products/database/htmldb/howtos/howto_file_upload.html
I have given a link to a procedure as follows, which will download the file (as given in the HowTo):
#OWNER#.download_my_file?p_file=#ID#.
However, this does not work. It tries to open a page rather than executing the procedure. It displays the page not found messagethat page not found message is a generic one. you'd want to check your apache logs for more info on what really happened. my guess is that you missed step 5 of that how-to, "grant execute on download_my_file to public"
hope this helps,

Stored Procedure call from JDBC sender for Oracle Database
Hi,
I have a requirement to call stored procedure using JDBC sender adapter for retriving data from an Oracle database.
I need to execute first stored procedure call from Querry SQL statement and then trigger second stored procedure call for confirming the succesful retrival of those records from the update SQL statement.
Querries:
1. Can we trigger stored procedure from Update statement of JDBC sender.
2. Can we call stored procedure from Querry statement, since I have read on other sdn threads that stored procedure calls on Oracle database are not allowed. If not possible to have "Execute stored procedure" would the function call (select * from table(function name)) work same as stored procedure.
3. In a JDBC sender the Querry statement and Update statement are executed in same session call and same database connection. What happens if the querry statement was not succesful, would the update be still triggered.
Please note PI does not have direct access to main table and hence the need to have separate stored procedure calls.
The PI version is PI 7.11 sp4.
Appreciate your inputs.
Thanks.
Siddhesh S.Tawate>1. Can we trigger stored procedure from Update statement of JDBC sender.
I think not possible using update statement.
> Can we call stored procedure from Querry statement, since I have read on other sdn threads that stored procedure calls on Oracle database are not allowed. If not possible to have "Execute stored procedure" would the function call (select * from table(function name)) work same as stored procedure.
Yes using select query you can call stored procedure.
>. In a JDBC sender the Querry statement and Update statement are executed in same session call and same database connection. What happens if the querry statement was not succesful, would the update be still triggered.
No select and update handles in the same session using the same thread so if one transaction fails update should not proceed. -
Stored Procedure call to Oracle - issue
hi ,
I am trying to call a receiver JDBC adapter to call an oracle stored procedure -
I got this error ->
java.sql.SQLException: ORA-06550: line 1, column 7: PLS-00306: wrong number or types of arguments in call - which I understand is related to mismatch btw the XML and Stored procedure
I checked the XMl and it matches the stored procedure call. I have two specific questions -
1) I have used SAP Note 801367 to have a look at the SQl command sent to the db.. However I do not see the stored procedure in the Audit logs...Does this feature work for Stored procedures too?
2) Can you look at the XML sent to the JDBC adapter...I saw something wierd... even though I had declared the isOutput attribute first and then attribute type... when I loaded the MT into the mapping the order changed...Does than matter?
<customer_id isInput="true" type="VARCHAR">5000123</customer_id>

Just to be sure: are all inputs to yourstored procedure of type varchar, or are there maybe inputs with different types?
A mismatch between the type specified in the XML and the expected inputs of the SP can also cause this error.

Stored procedure call returns null result set when using temp table in sp!
Here's a really odd problem...
SQL Server stored procedure called sp_Test takes 1 input INT. Here is the code I call it with
cStmt = connection.prepareCall("{call sp_Test(?)}");
cStmt.setInt(1, 44);
cStmt.execute();
rs = cStmt.getResultSet();When the body of the stored proc is
CREATE PROCEDURE sp_Test(@i_NodeID INT)
AS
BEGIN
SELECT node_id FROM tbl_NavTree
END
GOthe query works and I get all node_id back in rs
BUT when the body of the stored proc is
CREATE PROCEDURE sp_Test(@i_NodeID INT)
AS
BEGIN
CREATE TABLE #Descendants(
descendant_id INT
SELECT node_id FROM tbl_NavTree
DROP TABLE #Descendants
END
GOThe rs comes back as NULL. Really really weird if you ask me. I also tried removing the DROP TABLE line just in case the SELECT had to be the last statement but still NULL.
Final note is that BOTH the above stored proc bodies work when executed within SQL Server query analyser.
Must be JDBC .. what can it be!??DROP TABLE #DescendantsMS SQL Server - right?
Then don't drop the table.
From the MS docs for "create table"
Local temporary tables are visible only in the current session;
A local temporary table created in a stored procedure is dropped automatically when the stored procedure completes. The table can be referenced by any nested stored procedures executed by the stored procedure that created the table. The table cannot be referenced by the process which called the stored procedure that created the table. -
I've been trying to call a stored procedure through Entity Framework and WCF Data Services (OData). It returns an entity not a complex type. Following walkthroughs found all over the web, I came up with this code inside my service:
[WebGet]
public IQueryable<Entity> GetEntitiesByParameterId(int parameterId)
return CurrentDataSource.GetEntitiesByParameterId(parameterId).AsQueryable();
Calling the proc this way: ~WcfService.svc/GetEntitiesByParameterId?parameterId=1 executes
the stored procedure and returns entities that should be returned. No problem there.
Everything works well until I try to use $select OData option ie. ~WcfService.svc/GetEntitiesByParameterId?parameterId=1&$select=name.
Upon debugging, the method above runs without any error but it returns an Operation could destabilize the runtime error upon reaching the
client. After so much research, apparently it is a very general error pointing to a lot of different causes. I haven't found one that really matches my particular problem. Closest are
http://stackoverflow.com/questions/378895/operation-could-destabilize-the-runtime
https://social.msdn.microsoft.com/Forums/en-US/d2fb4767-dc09-4879-a62a-5b2ce96c4465/for-some-columns-entity-properties-executestorequery-failed-with-error-operation-could?forum=adodotnetdataservices
but none of the solutions worked on my end.
Also, from the second article above:
This is a known limitation of WCF DS. ...
Second is that some of the queries won't work correctly because LINQ to EF needs little different LINQ expressions than LINQ to Objects in some cases. Which is the problem you're seeing.
It has been posted on 2012. If it its true, are there still no updates on this? And is there any other workaround to get the $select working on the stored proc call?
What works:
~WcfService.svc/GetEntitiesByParameterId?parameterId=1
~WcfService.svc/GetEntitiesByParameterId?parameterId=1&$top=1
~WcfService.svc/GetEntitiesByParameterId?parameterId=1&$skip-5
~WcfService.svc/GetEntitiesByParameterId?parameterId=1&$filter={filter query}
~WcfService.svc/GetEntitiesByParameterId?parameterId=1&$expand=SomeNavigationProperty
What doesn't work:
~WcfService.svc/GetEntitiesByParameterId?parameterId=1&$select=name
Tech details:
EntityFramework 5, WCF Data Service 5.0, OData V3
*I've also tried upgrading to EF6 and WCF 5.6.2 and it still didn't work.
Any help would be appreciated. Thanks!Someone from SO replied to my question there and said that $select is still not supported though I couldn't find any definitive documentation about it.
From what I gather and observed, $select breaks the stored procedure call because it tries to alter the data shape already gotten from the database and attempts to return a dynamic entity instead. Something about the stored proc returning an ObjectResult might
be messing it up. As I have said, these are merely my observations.
Workaround: I found a simple and elegant workaround for it though. Since my stored procedures are only getting data from the database and does
not alter data in any way (INSERT, UPDATE, DELETE), I tried using table-valued functions that returns a table equivalent to the entity on my EF. I've found that calling this function on the Service Operation method returns an IQueryable<Entity> which
is basically what is needed. $select also works now and so does other OData query options.
Steps:
Create a function on the database
Update EDMX -> Add function
Add new Function Import with Entity return type
Create service operation in WCF Data Service that calls CurrentDataSource.<FunctionName>()
Test in fiddler.
CODES
Database Function:
CREATE FUNCTION GetEntities(@parameter)
RETURN @entites TABLE(
[Id] [int],
[Name] [nvarchar](100),
AS
BEGIN
INSERT INTO @entities
SELECT [Id], [Name], ... FROM [EntityTable]
RETURN
END
WCF:
[WebGet]
public IQueryable<Entity> GetEntity(int parameter)
return CurrentDataSource.GetEntity(parameter);
It doesn't really solve the stored procedure problem but I'm marking this as answer until someone can provide a better one as it does solve what I'm trying to do.
Hope this helps others too. :) -
Too many arguments for stored procedure call
I have a stored procedure with 34 arguments, including the return value. I am trying to call it from java using JDBC thin drivers (jdk11, oracle815), but I get the "wrong number or types of arguments" error message. JDBC-OCI fails also. I saw a reference in this discussion group to there being a limit of 32 arguments for stored procedure calls from jdbc (posted 6/29/99). Is there such a limit? If so, is there a fix or workaround? If there is not a limit, how can I determine which argument is causing the problem?
Many thanks.

nullI must confess I still don't understand your problem. By rows ...
I have an sql that recodes a column and has 1450 rows. This doesn't work
although when I use the same with less rows 40-60 it works.... do you mean rows in the table or elements in the CASE() statement ?
From the 9i SQL Reference:
" The maximum number of arguments in a CASE expression is 255, and each WHEN ... THEN pair counts as two arguments. To avoid exceeding the limit of 128 choices, you can nest CASE expressions. That is return_expr can itself be a CASE expression."
According to the 10g docs the limit is the same there.

Regional settings influences jdbc stored procedure calls?
Hi,
We have a strange problem: we use a jdbc test client
that does a simple stored procedure call with one
input parameter (integer) and one output parameter
(integer). Like:
"? = callprocedure(?)" . The database resides on a different server.
The problem is: this only works when we use "netherlands" regional setting on the windows 2000 machine that
java client program runs on. If we switch to
"english (united states)" the call gives other results
in the output parameter / returns an error code.
Does this have something to do with the Locale of the
virtual machine? Or do I have to do something with
NLS_LANG to eliminate the behaviour that is dependent on
the windows regional settings? Please help!
Thanks,
Michel Schudel
We use the Oracle JDBC thin driver, latest version.
(archive: classes12.zip)Ok, here it is. Basically, I first call a stored procedure called SETPARAM which receives two Strings:
a parameter name and a a parameter value. After that, I
call a procedure called RUNSQLKIT without any input parameters. The output parameter is an integer that indicates the number of "cells" in the output message. After that, I start to retrieve the cells but that is not important here. What happens is: with Dutch regional settings, the number of cells is normal (387) but with
US settings, the number of cells is -1 (indicates an error.) Why? I use no dates or floating point values as
input/output!
Jvm version is 1.3.1_08, oracle driver is 8.1.7
(Oracle 8i) thin jdbc driver. Oracle runs on AIX.
conn = m_dataSource.getConnection();
// Setup the input params
stmtInput = conn.prepareCall("BEGIN Pck_Sqlmast.setparam(?,?); END;");
for (final Iterator iter = m_kitParameterNames.iterator(); iter.hasNext();) {
final String sName = (String) iter.next();
final String sValue = input.getParameter(sName);
if (sValue != null) {
stmtInput.setString(1, sName);
stmtInput.setString(2, sValue);
stmtInput.executeUpdate();
// Call the kit
stmtRun = conn.prepareCall("BEGIN ? := Pck_Sqlmast.runsqlkit(?); END;");
stmtRun.registerOutParameter(1, Types.INTEGER);
stmtRun.setString(2, m_kitName);
stmtRun.executeUpdate();
final int iCells = stmtRun.getInt(1);
Hi Michel,
Perhaps you would care to post some more information
including:
1. Entire error message and stack trace you are
getting.
2. The part of your java code where the error
occurs.
3. Java version you are using.
4. Oracle database version you are using.
5. Platform on which Oracle database is running.
Good Luck,

Remote Stored Procedure Call Dispatcher WEB WERVICE
Hello all,
Environment: Windows OS, Oracle 10g, mod_plsql
I am looking for solutions to the following problem:
A way to dispatch calls to stored procedures from client to server with a minimal impact on performance.
We are looking at two possible solutions:
1) Making a call to a Remote Stored Procedure Call Dispatcher (RSPCDispatcher) stored procedure through mod_plsql.
2) Making a call to a Remote Stored Procedure Call Dispatcher (RSPCDispatcher) stored procedure through a web service.
Solution 1) is not the preferred one as you may already know that mod_plsql will not be supported starting 12g.
Solution 2) is the one we prefer as we believe that web services will be ever more supported in the future. When we move to 11g we may turn this web service into a native one (avoiding overhead in the OC4J for hosting the web service etc.).
We are looking for code examples and information pointers of how we could implement this dispatcher as a stored procedure in a DB package. We know that the implementation should be similar to the one done for mod_plsql in the OWA schema but the code there is obfuscated, so we could not borrow ideas from there.
We are not sure how to deal with the generalization of the above stated problem. We need to be able to pass to this dispatcher the stored procedure package and name we are invoking, ordered list of parameters (or parameters map), and the transport strategy (XML, JSON, etc.).
Basically, we are notsure how to deal with the USING clause of the EXECUTE IMMEDIATE statement. We can dynamically generate the SQL statement corresponding to the stored procedure we want to call, but we are not sure how to bind the parameters we are passing?
Also, we know that EXECUTE IMMEDIATE may be slow sometimes. So if could avoid it, this could further improve performance.
Perhaps the run-time generalized stored procedure execution may not be what we are looking for?! Perhaps we should include several design-time steps?! What about a script that given a package name (or just a single stored procedure) would generate a wrapper package which stored procudures' names would correspond to their respective counterparts in the given package which would take two parameters - the list of parameters in some sort of format, and the transport (content delivery strategy) and would return the result in the given content delivery strategy?! This script may also define the XSD of the XML message a stored procedure is called with (the parameter map) as well as the XSD of the XML result the stored procedure returns. Also the script could generate client code with the given language strategy (Java, .NET, etc.) for calling the RSPCDispatcher web service.
We request the following from the Oracle community folks:
a) Please, give us any relevant information that could be helpful to resolve this problem.
b) Any resource of how to inspect stored procedures in a package, its parameters, parameter types and direction (IN, OUT, or INOUT), etc.
Thank you very much in advance.

DML visibility in stored procedures called via JDBC
Hello,
I have two stored procedures, A and B. Proc A inserts Q into table X. Proc B selects Q from table X to insert it into table Y. Neither procedure does a COMMIT.
My Java class executes Proc A and then Proc B within a transaction (autocommit is false). But Proc B fails to select Q from table X with the No Data Found error, apparently unable to see the recently inserted Q.
If these two procedures are called from a SQL*Plus block, everything succeeds.
Does anyone have a clue about what I am missing? All my DML should be visible to my session.
Thank you in advance for any suggestions.
- CJThank you, Joe, for your reply!
To the best of my knowledge, all of my stored procedure calls are being made from the same connection so I can rollback everything if necessary. I have not explicitly closed the connection between calls. The debugger indicates my connection session id never changes across calls.
Do you know of any JDBC trace tools that might help me verify my connections? I've enabled logging with oracle.jdbc.driver.OracleLog.setTrace(true) but it doesn't really give me specific connection information - at least not that I can tell. :)
Thanks!

ManuelYou need to use a DataModifyQuery as your query does not return anything.

JDBC callableStatement stored procedure call cancellation?
up vote0down votefavorite
I have a very complex oracle stored procedure that searches and retrieves some data. The procedure returns an output parameter - an oracle cursor. I execute the procedure by JDBC:
CallableStatement stmt = conn.prepareCall("{call myprocedure(?,?,?,?}");
The problem is, the queries can sometimes take quite long (few minutes) and i would like user to be able to cancel the query anytime by clicking button. I have reference to stmt object, but unfortunatelly calling stmt.cancel() (from other thread) has NO EFFECT.
On the other hand when i change the CallableStatement sql to some query like:
CallableStatement stmt = conn.prepareCall("select * from all_objects");
i get "java.sql.SQLTimeoutException: ORA-01013: user requested cancel of current operation" after calling stmt.cancel() - so thats the right reaction.
Does that mean than i cannot cancel stored procedure call via jdbc, but only simple select statements? Does anyone else had and resolved similar problem?
I guess i could cancel the query by oracle kill session, but i use connection pooling (jboss) and i have plenty of sessions for the same user existing.
Database Product Version is Oracle Database 11g Enterprise Edition Release 11.2.0.4.0 - 64bit Production JDBC Driver Version is 11.2.0.4.0
any help will be appreciated.This property didnt help, still no reaction after statement.cancel().
I could not cancel the statment from the db size , so i decided to spawn new java thread and run the statement in that thread, and when user clicks cancel button i just cancel the thread, some snipper of code below:
AtomicBoolean userCanceled - this must be AtomicBoolean or volatile variable, so other threads would see the change of variable after clicking button
try{
MyCallableQuery callable = new MyCallableQuery(rs,stmt,this,rsh,outParameter);
FutureTask<T> queryTask = new FutureTask<T>(callable);
ExecutorService executor = Executors.newFixedThreadPool(1);
executor.execute(queryTask);
while (!queryTask.isDone()){ //stil processing statement
Thread.sleep(100);
if (userCanceled)){ //user decided to cancel
futureTask1.cancel(true);
executor.shutdown();
throw new SQLException("User decided to cancel procedure call");
result = futureTask1.get();
//here the code after the resultset has been processed without cancelation
catch (SQLException e}{
//here the code when user decided to cancel like clearing the datatable
and my callable class is like:
public class MyCallable<T> extends ProcRunner implements Callable<T> {
private ResultSet rs;
private CallableStatement stmt;
private ProcRunner procRunner;
private ResultSetHandler<T> rsh;
private Integer outParameter;
public MyCallable(ResultSet rs,CallableStatement stmt,ProcRunner procRunner,ResultSetHandler<T> rsh,Integer outParameter){
this.rs = rs;
this.stmt = stmt;
this.procRunner = procRunner;
this.rsh = rsh;
this.outParameter = outParameter;
@Override
public T call() throws Exception {
T result = null;
stmt.executeUpdate();
rs = (ResultSet) stmt.getObject(outParameter);
rs = this.wrap(rs);
result = rsh.handle(rs);
return result; -
Pass a null value to a JDBC stored procedure call?
pass a null value to a JDBC stored procedure call? Is this even possible? My DBA gave me a procedure to call that sometimes requires a null value. I don't think this is even possible.
do you mind tell me how to resolve your problem?i using the setnull method,but it doesn't work.
