I'm using ASP.NET C# with the v3.5 framework, and need to grab data from the session and insert it into an Oracle database. I can connect to the database and manually insert data from a couple of controls I created. However, I have an application with multiple forms that stores data in the session as the user navigates between the forms. The form information is stored in DataTables, with a separate DataTable for each form. I have an idea of how to retrieve the data, but was wondering if I have to code queries to map each field in the database to the fields in the forms? Or is there a way to "give" the database the information from the DataTable and have it insert each of the values?
I want to do a bulk data transfer from Oracle 10.2G into CSV or Excel sheet.I would either want that an entire table's data be populated into EXcel/CSV or the result of a select query be so populated.
1)Is there any stored procedure or function that can do this?
I know of a function in postgres which does this kind of a thing.There could be something similar.The second thing is the reverse of it.I want to transfer the contents of a CSV file into a oracle table after truncating it.
2) What sp or function is available for that?
I want to know the best way to transfer data from a view in Oracle database 10g to Sql Server 2008.

Oracle gives me creeps with these invalid characters and dates.
Ours is a Asp.net web application. Database is Oracle. Its an Internet Application.
Database will be in one location and Web application in another. Data from Oracle to Web application will be passed over Internet.
We are using EnterpriseLibrary. And provider is System.Data.OracleClient.
We need a provider which encrypts the data while passing data over internet.
Do we need to go for some third party Providers or ODBC ?
I am fetching data from oracle data base in asp.net application. To achieve this functionality i have used Oracle.DataAccess dll . In my developement enviorment it working fine.
But once I deployed this code on IIS 6.0 it is stopped working and I checked my log and found connection not get established . Then I make sure Oracle.DataAccess.dll present in to bin folder also I try to put this dll in side GAC, but still my code is not working on deployed server.
Getting the following error when browsing .net 2.0 application System.Data.OracleClient requires Oracle client software version 8.1.7 or greater.
I have setup a .net 2.0 application with oracle backend on windows server 2008 R2. I have oracle client 11g installed on the server for the application to talk to the oracle database. This worked well when the .net 2.0 application was hosted on windows server 2003 and oracle client 10g. But when it is hosted on server 2008 with new oracle client it is giving the above error when browsing the page. This error occurs when the connection is opened inside the c# code.
I need to develop an application, which will get records (orders) from one application and process them. The updates to this records (order updates) will be sent back to the source application for end customer reference. I'm planning to achieve this data synchronization at the database level using triggers and stored procedures to insert database between the 2 databases.
But, the issue is I have to deploy this application in 3 different customer sites and I have to change the database names (cannot use the same database name) in each deployment manually. Because of this deployment issue, I was thinking of handling this within the asp.net application where I can store the db name in the database and then build the query within the application, but I dont want to do it as building queries like that doesnt look very professional.

View 1 RepliesI 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 ??
