Code sample using Oracle Provider

Hi Is any got code sample using Oracle Provider with aspnet app

Assuming your stored procedure is returning a REF CURSOR, it cannot be done. Oracle's REF CURSORS are read only constructs.

XML queries... Change the code from using Oracle db into MS SQL

Hi, I am a new begginer in this field. I came accross to an article that focuses in Oracle's XSU approach.
Currently, i am trying to convert the java code from using Oracle db to MSSQL db. The code has shown below:
import javax.naming.*;
import javax.sql.*;
import java.sql.*;
import oracle.xml.sql.query.*;
public class testxml
     public static void main(String args[]) throws SQLException, NamingException
     String tabName = "emp";
     int maxRows = 3;
     Context ctx = new InitialContext ();
     DataSource ds = (DataSource) ctx.lookup ("MyOra");
     Connection conn = ds.getConnection ();
OracleXMLQuery qu = new OracleXMLQuery (
conn, "select EMPNO, ENAME from " + tabName);
qu.setMaxRows (maxRows);
qu.setRowsetTag ("EMPLOYERS");
qu.setRowTag ("PERSON");
String xmlString = qu.getXMLString();
System.out.println (xmlString);
conn.close ();
Currently, i am having difficulties to change the "bold" area that uses Oracle into MS SQL as my current application is using MS SQL as the database.
Please help and need more advices from all of you. Thank You

I resolved this issue myself. For the answer please message me.

Any code samples using StringWriter?

I looked through the examples here and couldn't find one that used StringWriter. Does anyone know where a code sample using it can be found?
Thanks

OK... I got a small sample program to work but I am having trouble getting this one to work with StringWriter. I get an error on the line containing ---- s = new String(sw.toString); It says it can't resolve symbol. Here is the part of the code that is giving me trouble.
try {
               fin = new FileInputStream(args[0]);
          } catch (FileNotFoundException e) {
               System.out.println("File not Found");
               return;
          } catch (ArrayIndexOutOfBoundsException e) {
               System.out.println("Usage: ShowFile File");
               return;
          do {
               i = fin.read();
               if (i != -1) {
                    pw.print(i);
          } while(i != -1);
          fin.close();
          s = new String(sw.toString);
          StringTokenizer st = new StringTokenizer(s);     (I didn't put the import statements, variable declarations or main line for clarity). I also tried putting sw as the argument for StringTokenizer() as well and it didn' work.
Any help would be great.
Thanks

Boolean types with entity framework code first and oracle provider

Working in a application that has to work in oracle and sqlServer. In SqlServer we have used "Bit" to store booleans and in oracle number(1).
Have check other threads in this forum, but didnt find any that fix my problem, sorry if this may have been discused before.
We have created a code first model were we find few bool properties mapped to database fields.
for example:
public partial class ZPruebaBooleano
public int Numero { get; set; }
public bool Booleano { get; set; }
Mapped as:
this.ToTable("ZPRUEBABOOLEANO", schema);
this.HasKey<int>(t => t.Numero);
this.Property(t => t.Numero).HasColumnName("NUMERO");
this.Property(t => t.Booleano).HasColumnName("BOOLEANO");
Also, sw added to the application configuration file (for simplicity we have test it without the use of any additional dll):
<oracle.dataaccess.client>
<settings>
<add name="bool" value="edmmapping number(1,0)" />
<add name="byte" value="edmmapping number(3,0)" />
<add name="int16" value="edmmapping number(4,0)" />
<add name="int32" value="edmmapping number(9,0)" />
<add name="int64" value="edmmapping number(18,0)" />
</settings>
</oracle.dataaccess.client>
I am confident that the provider factory read it when creating the model, because it provokes an exception if i add an invalid entry in any of the type names mapped in the file.
As i have find in other forums, this should work. But now i am not sure if should work always, including code first.
I have this exception when i excecute the code (translated from spanish, sorry for any mistake):
Type 'Edm.Boolean[Nullable=False,DefaultValue=]' from 'Booleano' to type'PruebaBooleanos.ZPruebaBooleano' is not compatyble with 'OracleEFProvider.number[Nullable=False,DefaultValue=,Precision=38,Scale=0]'
Its funy that says Precision=38. The database is Number(1), i am sure about that, in fact this is the script:
CREATE TABLE ZPRUEBABOOLEANO
NUMERO NUMBER(15),
BOOLEANO NUMBER(1)
Also, i find it interesting that i was having this mistake even when i was not informing the table i was maping, like if the oracle provider didnt even check if the column was number(anything). Right now is well maped, table and schema.
I have test to create an integer property wrapped by the boolean one, as we can see in this code.
namespace PruebaBooleanos
public partial class ZPruebaBooleano
public int Numero { get; set; }
public bool Booleano
get
return iBooleano == 1 ? true : false;
set
iBooleano = value ? 1 : 0;
public int iBooleano { get; set; }
in this last case i ignored the boolean and mapped the integer.
That worked ok in oracle. But added 2 problems:
1. It fails in SqlServer, because in sql server is bit
2. Cant query the entity model using the boolean property as it is not maped to Database.
I could change the bit field in SqlServer to Number.
But i would like to keep bit in sqlserver and number(1) in oracle.
Anyone had a similar problem?
I am open to any ideas, thanks !!!
libo

It's cool. :)
Sure. I can upload an EDMX file that works against my database if you want to look at it. The relevant parts are probably much like you'd expect. I've removed some columns from this version to make it easier to read.
From the SSDL:
        <EntityType Name="PARAMETER">
          <Key>
            <PropertyRef Name="PARAMETER_CD" />
          </Key>
          <Property Name="PARAMETER_CD" Type="number" Nullable="false" Precision="4" />
          <Property Name="PARAMETER_ACTIVE_INDR" Type="number" Nullable="false" Precision="1" />
        </EntityType>From the CSDL:
<EntityType Name="PARAMETER">
          <Key>
            <PropertyRef Name="PARAMETER_CD" />
          </Key>
          <Property Type="Int16" Name="PARAMETER_CD" Nullable="false" />
          <Property Type="Boolean" Name="PARAMETER_ACTIVE_INDR" Nullable="false" />
        </EntityType>From the C-S mapping:
<EntitySetMapping Name="PARAMETER">
            <EntityTypeMapping TypeName="Model.PARAMETER">
              <MappingFragment StoreEntitySet="PARAMETER">
                <ScalarProperty Name="PARAMETER_ACTIVE_INDR" ColumnName="PARAMETER_ACTIVE_INDR" />
                <ScalarProperty Name="PARAMETER_CD" ColumnName="PARAMETER_CD" />
              </MappingFragment>
            </EntityTypeMapping>
          </EntitySetMapping>Also worth noting that the EDMX mapper probably won't set the provider and token correctly:
<Schema Namespace="Model.Store" Alias="Self" Provider="Oracle.DataAccess.Client" ProviderManifestToken="11.2" xmlns:store="http://schemas.microsoft.com/ado/2007/12/edm/EntityStoreSchemaGenerator" xmlns="http://schemas.microsoft.com/ado/2009/02/edm/ssdl">Full version is available at http://www.hiredgoons.ca/DataImport.edmx . This is an early development one so I make no apologies for not renaming columns to something readable. ;) It does work correctly as I've had it in testing (taking data from a 170MB excel file and putting it into Oracle using the model). It was created using DB First.
When you have it load at runtime, you need the application configuration settings to map bool to number(1). If that's in app.config or web.config it'll pick it up. Probably worth noting that if you don't have the configuration setting and you load this, the model doesn't validate correctly. As soon as you try to create a DbContext from it, you get an immediate exception that number(1) doesn't map to boolean.

Crystal Reports can't add stored procedure using Oracle Provider for OLE DB

Hello,
I am trying to bind an oracle stored procedure to a crystal report through Visual Studio 2008.
This oracle stored procedure returns a ref cursor.
I am using an oracle 11g database (11.2.0.2.0) .
When I use the Oracle Provider For OLE DB driver to bind the store procedure with the report, I get the following error message:
Description : ORA -06550 Line 1 Column 7
PLS 00306 wrong number of types or arguments to the "Strored Procedure Name"
But When I use the Microsoft OLE DB provider for oracle driver, I can bind the stored procedure to the report successfully .
I cannot use the Microsoft OLE DB provider for oracle driver because it does not support the CLOB data type which I plan on having the stored procedure return once I can get everything working.
I have tried setting PLSQLRSET = 1 IN "HKEY_LOCAL_MACHINE\SOFTWARE\KEY_OraDb11g_home1\OLEDB", but that does not seem to work either
Any assistance would be greatly Appreciated
My Stored procedure is very simple as the moment (I just need to get it working then I'll add more stuff). Here's what it looks like:
CREATE OR REPLACE PACKAGE PROMO.PKG_REPORT as
TYPE OUT_Type IS REF CURSOR;
procedure Report_ThisReport (
p_ThisIdField IN number,
IO_CURSOR IN OUT OUT_Type
end PKG_REPORT;
CREATE OR REPLACE PACKAGE BODY PROMO.PKG_REPORT as
procedure REPORT_ThisReport (
p_ThisIdField IN number,
IO_CURSOR IN OUT OUT_Type
IS
BEGIN
OPEN IO_CURSOR FOR
SELECT ThisField
FROM ThisTable
WHERE ThisIdField = p_ThisIdField ;
END REPORT_ThisReport;
end PKG_REPORT;

It seems that some questions posted here on the XE forum are really questions about other Oracle technologies.
Concretely, for you there is an Oracle Provider for OLE DB Forum that is active and a terrific resource for you to use.

Installing a VB application using Oracle Provider for OLEDB

Hi all,
I have a corporate VB application that uses the Oracle 9i client.
The Oracle Client is on a network disk, so all my clients will not need to install on their client machines.
I am using Wise for Windows Installer to install the application on each client machine.
I need to include on the installation package the "Oracle Provider for OLEDB" files.
How can I do this?
Thank you all,
Ardates Cruz.

The standard way to use the unmanaged Oracle.DataAccess is to install an Oracle client on any machine that wants to use the application.
It is possible to avoid that installation by including a bunch of DLLs and some other files in the application, but it's far more cumbersome than using the managed client. Here's a link to get you started on that: http://stackoverflow.com/questions/13721025/deploying-and-configuring-odp-net-to-work-without-installation-with-entity-frame

Access Oracle from SQL Server using Oracle Provider for OLE DB

Using
- SQL Server 2000 SP4
- Oracle 10g
- Oracle10g Provider for OLE DB Version 10.1.0.4.0
- Oracle 10g client
Able to create linked server in SQL server to Oracle 10g and display list of tables in Oracle. However, when execute query, it gives
Server: Msg 7320, Level 16, State 2, Line 1
Could not execute query against OLE DB provider 'OraOLEDB.Oracle'.
OLE DB error trace [OLE/DB Provider 'OraOLEDB.Oracle' ICommandText::Execute returned 0x80040155].
Any idea what is the problem ?

I'm having the same error message...But I'm connecting to a Oracle 8i DB......
I think this has to do with SP4 for SQL....I will test this tonight....

Oracle Provider for OLE DB 10.1.0.2.0

Hi,
I installed 10g client on my local PC to get access to an ASP application using 10g database. The select always returns no row for a username, therefore, I could not login to the application. But the sqlStatement in SQL*Plus did return a row. More strangely, one script also uses Oracle Provider for OLE DB 10.1.0.2.0 works without any problem.
In Oracle Provider for OLE DB 10.1.0.2.0 documentation, it has the following as system requirements:
System Requirements
The following items are required on a system to use Oracle Provider for OLE DB:
1.Windows NT, Windows XP, Windows 2000, or Windows Server 2003
2.Access to an Oracle database (Oracle8i or later)
3. Oracle Net Services
4. Redistributable files provided with Microsoft Data Access Components (MDAC) 2.1 or higher are required by the provider. These files are available at the Microsoft Web site:
http://www.microsoft.com/data/
5. Oracle Services for Microsoft Transaction Server release 10.1 or higher. This is required for consumers using Microsoft Transaction Server (MTS) or COM+.
I think that I might need to download the Microsoft Data Access Components (MDAC). I went to Microsoft web site, and the latest version for MDAC is 2.8. Anybody has any experience with this? Am I on the right track? I don't want to mess up with my machine by installing MDAC 2.8 if it does not solve the problem.
Thanks, and your early reply is greatly appreciated.
Jane

Well, if some of the required componets were missing, I would imagine you getting an error when trying to connect?
Where is this ASP application actually running?
Is it running on your localhost IIS web server?
If not, any setup on your computer will be irrelevent.
If it is, you need to install MDAC components, and 2.8 is the latest.
If running on your local IIS, did you try to create a very basic ASP page which just creates a connection to the database in question? Does that work?
Do you have ON ERROR statements in your code to bypass any/all SQL errors?
If you create a simple UDL file on your desktop and specify the server/user/password (ater selecting Oracle OLEDB driver), does the connect button work?

Oracle Provider for OLE DB - Security

Hi,
Appreciate if anyone can advise on the security of data when using Oracle Provider for OLE DB to connect from a client application to Oracle database.
Is the data encrypted?
Thanks.
oh2l

First, technical questions should be addressed to an appropriate technical forum. Technologies | Windows | OLE DB would be a good place for this question.
All client applications, regardless of which API they use, rely on TNS (Transparent Network Substrate) to communicate with the database. You can use Oracle Advanced Security to secure the contents of all the Oracle connections on that machine, but by default, all data (other than the password) goes over the wire unencrypted.

Intall Oracle Provider for OLeDB version 8.1.6.2.0

I have one pb while Installing Oracle Provider for oledb Vers 8.1.6.2.0 (Os: Windows98 Compaq computer)
/win32/Setup.exe occurs Windows Error
Error Message (in french) : Jrew a cause defaillance de page dans le module JAVAI.dll
Dou you think that the next version of Oracle oledb provider resolvs this error?

I used Oracle Provider for OleDB 9.2.0.4 (which is the most actual as far as I know) even with an Oracle 8i database.
The 9i OleDb drivers are more reliable than the 9i and they seem to work fine with 8i databases.
Unless you use some very specific features, this may be an option.

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.

ORA-00911 Error code in JDBC where no special character is used - Oracle 10

Hi,
I am using Oracle 10G and Tomcat 5.5. I am trying to update a the CONFIRMED column of a table called LISTSERV_WAITING_LIST_TABLE. Please see my code below.

update listserv_waiting_list SET CONFIRMED = 'YES' WHERE UEMAIL = '[email protected]' and USERID = '1142369642862';
It contains no stange character and rows are inserted successfully in another class of the program that uses the same mechanism. The problem comes when I update the table.
Any idea as to what is wrong? Your help will be appreciated.
Thanks,
Nguessan

buddy, why don't you use a stored procedure and make your update, i hate that upkeeping.
callablestatement and the power of Plsql are ur saviours.
