Invoke/Return Dataset from WebService in CLR Stored Procedure

Hello,
I am running SQL Server 2008 R2 or 2012 and Visual Studio 2010 Premium sp1. I have a stored procedure which currently returns a dataset which is used via SQLDataReader within a C# code-behind module in an ASP.NET application. This application uses the .NET
4.0 framework.
I need to join the results from an external webservice (but within the same network) to this dataset. Instead of getting the data and putting it into a data table in code-behind (probably a HashTable which I could join with key/value pairs), I would like
to get all of the data in the same stored procedure. I was thinking I could invoke the webservice and pass the input parms to the webservice then put the results into a temp table which I could then join with the query to the physical table.
So, I have done quite a bit of researching online but have been unable to find any definitive answer or solution. I read the related forum thread "CLR Stored procedure consume webservice" but this does not address my versions of SQL Server / .NET
framework.
If someone could offer any suggestions or point in the right direction I would greatly appreciate it. Perhaps what I am trying to do is simply not possible?
Regards,
Buster

Calling Managed CLR Stored Procedure from C++ SQL Server 2008 fails with Msg 2809

I am trying to call a stored procedure from C++ (VS 2010).
Here is what the stored procedure looks like:
public class Validate
[Microsoft.SqlServer.Server.SqlProcedure(Name = "ClientTest")]
public static void ClientTest(out String res )
{ res = "50";}
To create a stored procedure I deploy at first the assembly
USE [test]
GO
CREATE ASSEMBLY ClientTestAssembly
AUTHORIZATION testLogin
FROM 'C:\Users\test\Documents\Visual Studio 2010\Projects\TestCreationAssemblyCSharp\TestCreationAssemblyCSharp\bin\x64\Debug\TestCreationAssemblyCSharp.dll'
and call
USE test
GO
CREATE PROCEDURE ClientTest (@res NVARCHAR(40) OUTPUT)
AS
EXTERNAL NAME ClientTestAssembly.Validate.ClientTest
I can call my procedure direct in SQL Server Management Studio without any errors
declare @res nvarchar(10)
execute ClientTest @res OUTPUT
print @res
But when I try to call this procedure from C++ using CALL syntax
SQLBindParameter(sqlstatementhandle, 1, SQL_PARAM_OUTPUT, SQL_C_CHAR,
SQL_VARCHAR , 40, 0, version, sizeof(version) ,
&pcbValue);
res = SQLExecDirect(sqlstatementhandle, (SQLCHAR*)("{CALL ClientTest(?) }"), SQL_NTS);
I get the Error 2809 with SQLSTATE 42000 and with statement
The request for 'ClientTest'
(procedure) failed because 'ClientTest' is a procedure object.
However, if I wrap my CLR stored procedure into a T-SQL stored procedure, like
CREATE PROCEDURE myProc (@res NVARCHAR(40) OUTPUT)
AS
EXEC ClientTest @res OUTPUT
and call then myProc instead of ClientTest
res = SQLExecDirect(sqlstatementhandle, (SQLCHAR*)("{CALL myProc(?) }"), SQL_NTS);
everithing works fine and I get 50 as result.
I have no ideas what is the reason for that behavior.
Thanks very much for any suggestion.

I'm not an ODBC expert, but you might try following the sample here:
Process Return Codes and Output Parameters (ODBC)
To see if it also behaves differently for your CLR proc.

Using C# instead of pl/sql in a CLR stored procedure, benefits?

Hello dear experts,
I was just playing around with C# and a little stored procedure I deployed to my Oracle 11.
My questions are:
Is it possible to call this "CLR c#" stored procedure in a different way than I call a standard pl/sql stored procedure from a C# client, maybe by something like referring to the same c# classname which I chose to wrap the stored procedure/function in?
Is it possible to eg. return c# classes or c# arrays / own datatypes created within the CLR stored procedure to a C# client?
Can I build up a c# array within my oracle c# stored procedure and return it to a C# client directly, or do I still have to do all the marshalling based on the standard pre-defined data types (number, varchar2 etc) myself and copy them to c# class members?
Example: I have c# stored procedure like this:
namespace oracle
public class Crosssorter
public static int GetChute(int parcelNo)
int nChute=0;
OracleConnection dbcon = new OracleConnection();
dbcon.ConnectionString = "context connection=true"; // Wir benutzen die Session des Aufrufers
dbcon.Open();
OracleCommand cmd = dbcon.CreateCommand();
cmd.CommandText = "select ChuteNo ...[blabla] ";
cmd.Parameters.Add(":1", OracleDbType.Int32, parcelNo, ParameterDirection.Input);
OracleDataReader reader = cmd.ExecuteReader();
while (reader.Read())
nChute = reader.GetInt32(0);
reader.Close();
cmd.Dispose();
return (nChute);
Can I reuse the class "Crosssorter" within my c# client application in order to access the function 'GetChute' more easily or is this classname only chosen because it has to have a name?
Can I write an oracle C# stored proc so that a complex c# object is returned?
So instead of a simple thing like 'public static int GetChute(int parcelNo)' maybe something like
'public static int GetChute(
int parcelNo,
CChuteObject myChute)' <---- !!
where CChuteObject is a C# class?
In case all this is not possible, is there a solution to achieve this easily?
Thank you for reading and thinking.
Bernd.

SSRS dataset throws error when another stored procedure is called inside dataset stored procedure

Hello;
I am using Report Build 3.0, I have a simple report which gets data using dataset which is created from a Stored Procedure. I have another stored procedure which updates the data in the table which is used for the report. I want to get the live data on report everytime
the report is run so that I call that stored procedure (sp_updatedata) inside my report dataset stored procedure and here where my report fails as it throws error while creating dataset.
Here is sample:
sp_updatedata (this only returns "Command(s) completed successfully"
Create Proce sp_getReportData
As
Begin
Exec sp_updatedata -- I call it to update the data before it displays on the report
Select * from customers
End
If I remove this line it works.
Exec sp_updatedata -- I call it to update the data before it displays on the report
Thanks
Essa Mughal

Hi MESSA,
According to your description, you create a dataset based on a stored procedure. In this procedure, it calls another procedure. Now it throws error when creating dataset. Right?
In Reporting Services, when creating dataset, all the query or stored procedure will be executed in SSMS. So if the procedure can be executed in SSMS, it supposed to be working in SSRS. However, it has a limitation in SSRS. In a dataset, it can only return
one result set.
In this scenario, I don't think it's the issue of calling other procedure inside of procedure. Because we tested in our local environment, it works fine. I guess the sp_updatedata returns a result set, and the "select * from customers" returns
another result set. This might be the reason cause the error.
Reference:

If you still have any question, please post the error message and the store procedure (sp_updatedata).

Deserialization permissions error in CLR stored procedure

Environment: SQL Server 2008 R2 standard edition and VS2010, .Net Framework 3.5
I've got a table with a varbinary column that contains a serialized Hashtable. I'm writing a CLR stored procedure that, given the contents of such a field from a row in the table, does a lookup on a key in the Hashtable. and returns the element's value.
To get the Hashtable, I need to deserialize it, and it appears that the BinaryFormatter's Deserialize function requires certain permissions that I don't know how to grant.
This SQL Server instance runs on my own development machine, and was installed pretty much with all defaults. I'm the owner.
Any help on solving this? I should point out while I write a fair amount of SQL and a LOT of VB, I'm far from a SQL Server expert, so if you have suggestions I'd appreciate it if you'd spell things out clearly for me.
Thanks in advance for any help,
Tom

    Dim oHT As Object = formatter.Deserialize(ms)    'hurls here

UNSAFE ASSEMBLY permission and the database has the TRUSTWORTHY database property on; or the assembly is signed with a certificate or an asymmetric key that has a corresponding login with UNSAFE ASSEMBLY permission.
Here's an SQL script that runs it:

Set the database (in a test system) to trustworthy (ALTER DATABSE foo SET TRUSTWORTHY ON) for testing. If this works, look into code signing (sign an assembly and catalog the cert/asymmetric key to master) for production. If you have problems with
"native" serialization, you might get better results using XML serializers.
Re: XML serializers. SQLCLR will not load dynamically generated serializers. So you need to pregenerate XML serializers with sgen.exe.
Your specific error message (the permission error) might be fixed by cataloging the SQLCLR assembly as UNSAFE. If that doesn't work, you might attempt to change the .NET permission configuration on your machine using either of the tools described here:

SQL Server 2005 64-bit & SQL CLR Stored Procedures using DI API. COM Error.

Hi,
We've created a set of SQL CLR Stored Procs in C# .NET which use the DI API to import data into SAP (DEV was carried out on 32-bit environment).
The DLLs and Interop.SAPbobsCOM have been successfully deployed as assemblies on SQL Server with their permission set to UNSAFE on the following environment:
Microsoft Windows Server 2003 R2 Standard Edition 64-bit, Service Pack 2
Microsoft SQL Server 2005 - 9.00.3073.00 (X64)
SAP Business One 2007 A (8.00.180) SP:00 PL:45
When executing the SQL CLR Stored Procs from SQL Server Management Studio, the following error is returned:
"Retrieving the COM class factory for component with CLSID {632F4591-AA62-4219-8FB6-22BCF5F62007} failed due to the following error: 80040154."
From our understanding, this occurs because SQL Server loads the assemblies into it's 64-bit process space, whereas the SAPbobsCOM is 32-bit. Are we assuming correctly?
What can be done to solve this problem?

Hi Jeremy,
I'd agree with your assumption that it's to do with your DLL running in a 64 bit process. When you build your project, try setting the build properties to use a X86 instruction set (ie 32 bit).
More details here:
Re: Addon Develeped on 32bit Install on 64bit
I've never tried for a CLR stored procedure but this is how you get around the issue when running a DI API addon on a 64 bit machine so hopefully it will work if the dll is executed by SQL Server. Let us know how you get on.
Kind Regards,
Owen

Static variables in CLR stored procedures

Is there really no way to use static variables shared by several CLS stored procedures in the same DLL, except by making them read only?
Or can you add new server variables and read/write those from CLR stored procedures without having to open a connection and run a query each time you need a value?
In my SP's, I would like to know the path where the database's .mdf file is stored on disk (not to access that file, but to store other files in a location that's always the same relative to the database).
I thought I had found the solution last week, after some digging through sites like stackoverflow: make it a static read-only variable, and initialize it through a function call when the module is loaded. The CLR will "forget" that it is
read only at that time.
For some reason this has worked perfectly for a week, but today it suddenly started failing -- without any code change or even a recompile, it started after a simple reboot of the test machine.
The code (just the relevant lines, in VB syntax):
Private Shared ReadOnly Datapath As String = InitDataPath()
Private Shared Function InitDataPath() As String
Try
Using cn As New SqlConnection("context connection=true"),
cmd As New SqlCommand("SELECT TOP 1 [physical_name] FROM sys.database_files WHERE type=0", cn)
cn.Open()
The "cn.open" line throws "Data access is not allowed in this context."
It did not yet do that yesterday, and the day before, and all the way back to January 6th, when I wrote that piece of code. The DLL hadn't even been recompiled since then, I was working on the application that uses the database and the stored procedures.

I think I found it, at least it works again -- I just hope it's for more than a week now.
Declare assembly as unsafe when installing it in SQL server (it was already 'EXTERNAL_ACCESS' for file I/O, but non-read-only static variables require UNSAFE).
I initialize the static variables to 'Nothing' (NULL for C# users), and instead of finding the path when the module is loaded, I added a line 'if xxx is nothing then init()' at the start of each procedure / function. Init() is a a simple initialization
routine that initializes the static variables upon first access.
added SystemDataAccess:=DataAccessKind.Read to the declaration of UDF's (not possible and not necessary for procedures, apparently, but if what caused the assembly to load was a function, it would still fail).

Transpose Data in CLR Stored procedure

We have huge data table(600 columns and 800 rows approx) which we want to transpose 600 rows and 800 columns in a CLR stored procedure.
Currently am using a datatable to the transpose. Could anyone suggest any better options other than datatable which gives better performance?

Hi Hari,
If my understand is correct, please consider using unpivot or pivot sql:

How to return xmlType from Webservice generated with JDev and PL/SQL

Hi,
I have generated an PL/SQL package that's returning a value as xmlType.
With JDeveloper I'm deploying this package as a webservice. When invoking the webservice from a webbrowser the result looks like:
<?xml version="1.0" encoding="UTF-8" ?>
<SOAP-ENV:Envelope
xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<SOAP-ENV:Body>
<ns1:testXmltypeResponse
xmlns:ns1="http://app/webservice.wsdl"
SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
<return xsi:type="xsd:string">
<ROWSET>
<ROW>
<TODAY>12-OCT-07</TODAY>
</ROW>
</ROWSET>
</return>
</ns1:testXmltypeResponse>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
The problem is that the <return> tag contains 'xsi:type="xsd:string"'. And now the webservice response is not valid XML because the return value contains XML and not a string.
The solution would be, when invoking the webservice if the xsi:type would be missing from the result tag or would contains xsd:any. I tried editing the WSDL in JDeveloper and changing the type to xsd:any. After deploying and calling the WSDL from the webbrowser it contains this type. But when invoking the method from the webbrowser it still returns xsd:string as type.
How can I get rid of this type in the <return> or change it.
My JDeveloper version is 10.1.3.3.0 The Oracle database and 9iAS are 10.2.
Thanks in advance,
Thijs

How to get multiple out parameters from a pl/sql stored procedure in ADF Jdeveloper 11g release2

I´m trying to call from AppModuleImpl a stored procedure from my oracle DB which receives one input parameter and returns 5 out parameters.
I´m using jdeveloper 11g release2 ADF and I have created a java bean "ProRecallPlatesBean " with the atributes and accesors and I serialize it. just like in this article http://docs.oracle.com/cd/E24382_01/web.1112/e16182/bcadvgen.htm#sm0297
This is my code so far:
public ProRecallPlatesBean getCallProRecallPlates(String numPlates) {
CallableStatement st = null;
try {
          // 1. Define the PL/SQL block for the statement to invoke
          String stmt = "begin CTS.Pk_PreIn.proRecallPlates(?,?,?,?,?,?); end;";
          // 2. Create the CallableStatement for the PL/SQL block
          st = getDBTransaction().createCallableStatement(stmt,0);
          // 3. Register the positions and types of the OUT parameters
          st.registerOutParameter(2,Types.VARCHAR);
st.registerOutParameter(3,Types.VARCHAR);
st.registerOutParameter(4,Types.VARCHAR);
st.registerOutParameter(5,Types.VARCHAR);
st.registerOutParameter(6,Types.VARCHAR);
// 4. Set the bind values of the IN parameters
st.setString(1,numPlates);
// 5. Execute the statement
st.executeUpdate();
// 6. Create a bean to hold the multiple return values
ProRecallPlatesBean result = new ProRecallPlatesBean();
// 7. Set values of properties using OUT params
result.setSpfVal(st.getString(2));
result.setTransportTypeVal(st.getString(3));
result.setTransportCompanyVal(st.getString(4));
result.setCompanyDescrVal(st.getString(5));
result.setDGAPrint(st.getString(6));
// 8. Return the result
return result;
} catch (SQLException e) {
throw new JboException(e);
} finally {
if (st != null) {
try {
// 9. Close the JDBC CallableStatement
st.close();
catch (SQLException e) {}
In Jdeveloper I went into AppModule.xml JAVA>Client Interface section and expose "getCallProRecallPlates" Then I can see "getCallProRecallPlates" in Data Controls, I drag and drop it to a JSF page, an input text component and a button are generated in order to put in there the procedure input parameter (numPlates).
I don't know if I'm on the right track.
When I click the button, the "result" variable is supposed to be filled with data from the stored procedure. I want each of those values to be displayed in Output text or input text adf components but I dont know how. Thank you very much in advance I´m a newbie and i'll appreciate your help!

CallableStatement stmt3 = EyeHibernateApp.getHibernateSession().connection().prepareCall("{call answers_select_id( ? )}");
stmt3.setString(1,20);
stmt3.execute();
ResultSet rs1 = stmt3.getResultSet();
System.out.println("rs1 " + rs1); --> returns null
procedure-------------
CREATE PROCEDURE answers_select_id (IN question_id bigint )
P1:BEGIN
DECLARE cursor1 CURSOR WITH RETURN TO CLIENT FOR
SELECT a.answer_id from answers as a where a.question_id = question_id;
open cursor1;
END P1;
I am using the same java code with mysql stored procs . It works fine there but I assume open cursors in db2 stored proc is causing the problem . If I can help it , I need to maintain the same java code for mysql ad db2 . Please help me ...
Thanks,

Hi,
I am trying to do something like this but with Oracle stored procedure which returns an associate array and a cursor and these are defined as INOUT. I am not finding a way how to do it with editable row set. Can you plese list the steps used to make things work.
Thanks.

Trouble referencing return values of a Function in Stored Procedure

Hello all,
I have the following Function and Stored Procedure (simplified for this post). The error I am getting is in the SELECT, WHERE clause of the UPDATE command. My function is returning a sys_refcursor and I am trying to reference column names but keep getting the error
ORA-00904: "PUBLISHEDDOCVERSIONID": invalid identifier
What am I doing wrong?
Function
CREATE OR REPLACE FUNCTION &HKDB_Schema_Name..QueryKnowdeDocVersion(aKGID int)
RETURN sys_refcursor
IS
aCur sys_refcursor;
BEGIN
OPEN aCur FOR
SELECT pkd.KnowdeID as "PublishedKnowdeID", pkd.DocumentID as "PublishedDocID", pkd.VersionID as "PublishedDocVersionID"
FROM KnowdeDocument pkd
WHERE pkd.KGID = aKGID;
RETURN aCur;
END;Stored Procedure
UPDATE KnowdeDocument
SET DocumentID = (SELECT PublishedDocID FROM (SELECT QueryKnowdeDocVersion(aKGID, aPublishedKGID, aTextVersionID) FROM DUAL)
                  WHERE PublishedKnowdeID = KnowdeDocument.KnowdeID
                  AND PublishedDocID = KnowdeDocument.DocumentID
                  AND ((PublishedDocVersionID is NULL and KnowdeDocument.VersionID is NULL) OR (PublishedDocVersionID is not NULL AND
                           PublishedDocVersionID = KnowdeDocument.VersionID)))Regards,
Toby

Hi redeye,
Your select is from:
(select queryknowdedocversion(akgid
                              ,apublishedkgid
                              ,atextversionid)
                     from dual)This has no publisheddocversionid. Unfortunately I cannot figure out what you are trying to do with that ref_cursor.
Edit:
Or perhaps publisheddocversionid is a column in KnowdeDocument? Could this be case sensitive as well? (Bad idea to use quotations when naming things)
Regards
Peter

Retrive a new sequence value from a table using Stored Procedure

Dear experts
i have written the following stored procedure, but i want this to return itemid to the environment. Please help as i am absolutely new to oracle.
create or replace procedure "SP_ITEMS"
(vitem IN VARCHAR2,
vqty IN NUMBER,
vrate IN NUMBER)
is
begin
INSERT INTO ITEMS (item,qty,rate)
VALUES (vitem,vqty,vrate);
end;
Thanks
With regards

If you want a column to be automatically populated with a sequence, then you need to create a sequence, and create a trigger to populate the column with the sequence. You can use the returning clause in a select statement to return the value of the inserted sequence. You can do this with just sql or you can put it in a procedure. I have demonstrated both below. This is a general sql and pl/sql problem, not something specific to the Express Edition, so please post future such questions in the sql and pl/sql discussion group instead.
