Databases :: Oracle Store Procedure Does Not Return Any Thing In The Out Parameter
Oct 20, 2010
I am goig to execute an oracle store procedure using C# through through ODP.NET. The store procedure executes succsfully but it does not return any value in the out parameter.
When I execute the same store procedure with the same input parameteres from within SQL*Plus. It does return values.
This is to be clearify here that in the oracle store procedure the data type for the out parameter is number and in the c# the variavle that will hold its value is Integer. I also tried using Long on the C# side but it is still not working. After the successfull execution of the store procedure the C# variable contains nulll value.
i want to send mails internally and externally for eg. i want to send mail to my boss in the company and also to the customer which doesnt belong to our domain.
and also i want to attach an excel file which is stored in my computer. so how am i going to access that file through the same procedure and then attach the file and send it to both internal as well as external email ids.
we recently upgraded an application (.NET 2.0) that we maintain to use Oracle 11g. The application uses MS Enterprise Library 2.0. We've found that when the database.ExecuteNonQuery(Oracle.DataAccess.Client.OracleCommand) method is called, it bombs when the stored procedure expects a parameter as a number, but receives a string. This didn't happen prior to upgrading. If I cast the parameter to an Int, I don't recieve the error. Was something possible missed during the upgrade? The issue occurs regardless if we are hitting an 11g database, or a 10g database.
EDIT: I neglected to mention that this same issue does not occur when ExecuteDataReader is called (handles implicit conversion of the datatype).
i have a stored procedure and i want to return a value from that procedure and returned value i want to store in a variable Stored Procedure is create procedure simpleproc(OUT pcount int)begin set @pcount=(select count(*) from testtable); end
Now i call this proc from C# code
string query="CALL simpleproc(@count)"; MySqlCommand commond = new MySqlCommand(); MySqlParameter returnValue = new MySqlParameter("@count", DbType.Int32); returnValue.Direction = ParameterDirection.ReturnValue; commond.Parameters.Add(returnValue); commond.CommandText = query; commond.Connection = con; // I already set the connection in con and opened it commond.ExecuteNonQuery(); int count = Int32.Parse(command.Parameters["@count"].Value.ToString());
What should i have to change to get return value in count
I'm not so familiar with stored procedures but I'm interesting in moving most of my web selects to stored procedures. I'm working with .net based website and all my data access is something like this:
But now I want to improve some process and make tunings. For that I want to use stored procedures, so instead of the "SELECT ...." sentence I'll put stored procedure name. My problem is how to return a table from one.
I want to return integer result from storeprocedure.I have used dataset to return values.My store procedure which i have wrotewhich return three result 0,1,2I want to get this result..how to get that result.
I create an ASP.NET Crystal Report Web application using VS.NET 2010. In ASP.NET page, I stored two values in Session state and need to pass them as input parameters to Oracle stored procedure. In Crystal reports 2010 once you connect to a stored-procedure as data source, it automatically creates the parameter fields with Crytal Report Viewer. how I pass values to store procedure at runtime automatically.
I am executing a long-running Oracle stored procedure from .NET. The procedure takes about three hours to run. Ideally, the user should be able to kick off the procedure, close the browser, and come back later to check the results.
The problem is that the connection to the Oracle procedure is lost after exactly an hour. As you would expect, the Oracle procedre runs to completion if it is executed from SQL Plus. Strangely enough, it will also run to completion if I run in debug mode on my local machine (I start two threads, one of which executes the procedure. I set a breakpoint on the second thread).
Here is my connection string:
data source= (DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=serverx)(PORT=1521)))(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=TestSID)))
I have an update function in my data layer which is defined as:
public int UpdateRBTable(parameters ...) This calls a SQL Server Stored Procedure to perform an update function on the database.
The process does its job for updating the table. However, the stored procedure has a return value (which indicates how many rows were updated), but this return value is not returned to the application. The application always shows that a zero was returned from the stored procedure.
As the title says I have a Win 7 64 bit dev machine, Win 2K3 32 bit production box and I run against Oracle 10g which Oracle clients do I need to run? Do I need to run the Oracle 32 and 64 bit clients? And if so what versions?
I need to find a way to connect to the remote Oracle server without a DSN. There are some practical problem for accessing the server using a DSN. I need a way to connect to Oracle server like I connect to SQL Server etc. For example, in SQL server, I can connect directly with server using Servername (IP adress) + Username + Password + DB Name. Any way to connect to the Oracle server like in SQL Server we do ??
I have an Asp.net web application targeting .Net2.0 and my databse is oracle, I used SqlDataSource Control to communicate with oracle database its working fine on my development server, but on my production Oracle is 64 bit so im getting an error like
"<asp:ControlParameter doesnot have a property DbType="Int32"> " i tried with Int64 also but still im getting the same error
following is the markup of sqldatasource i used < asp:SqlDataSource ID="sdsEmployees" runat="server" ConnectionString="User Id=user;pwd=user1;server=prod" ProviderName="System.Data.OracleClient" SelectCommand="GetEmployeeInfo" SelectCommandType="StoredProcedure" OnSelecting="sdsEmployees_OnSelecting"> <SelectParameters> <asp:ControlParameter ControlID="txtNumber" DbType="Int32" /> </SelectParameters> </asp:SqlDataSource>
