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?

View 3 RepliesI developed a web site more then a year ago with .net2.0/c#/mssql 2005. it works fine but i was asked to replace mssql with mysql.
I wrote a class to complete data access works (unfortunately, I didnt use nhibernate or other data access tools :((
I edited the class to use System.Data.Odbc objects rather than System.Data.SqlClient.
It works fine in selecting data but not manipulating data. when i try to insert new data it adds null data for all fields in the table.
in debug mode, i noticed that it might be caused by OdbcParameter but not sure.

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 ??

I'm using oracle for my asp.net website. In website I have 3 different roles. Now do I need to create as many diff users in oracle as roles?
Someone in team insisted on having as many users in oracle. But then unnecessarily i have to maintain multiple connection strings in app.
like, I have manager/ team leader/ user roles.
Now the team member insists on having 3 users in oracle. then in DAL i've to check role and use corresponding connection string.
This is not very big app, but in all 12-15 aspx pages and some 10 table in oracle to be used only on intranet.
what is best practice for this?
I've developed a web app in Visual Studio 2008 using ASP.NET which connects to an Oracle database and a separate SQL Server 2005 database in the same application.
I want to convert this application to use SQL Server only. I have copied the Oracle tables that I need to SQL Server and am in the process of converting the SQL queries from Oracle format to SQL Server format.
I have also modified all the Connection Strings in web.config to point to the SQL Server database now and not the Oracle one.
However I have come across a problem. The TableAdapters are configured to use the OracleClient in the declarations code behind the scenes, i.e. it is "hard coded". But this causes problems of course while modifying/saving queries, because I don't want any trace of Oracle in my new web app.
The only thing I can think of is to delete all my TableAdapters and re-create them all.
I need to transfer SQL Server databse to Oracle database.
View 2 RepliesIn my web page I have written code that writes to a table in Oracle 9i. What I find is add ing or querying the table in Oracle is very slow. I tried doing the same with SQL server database and the process if 5 times faster than Oracle. In the Oracle or SQL table I have not created any indexes / primary keys, but still I find the SQL is way faster than Oracle.
Is there any way that I could improve the speed in Oracle? My table has 3 columns (PRVal, FACVal and UserID). And when the user is selected from the web page I retreive the values from the database, using a direct sql (no pl/sql stuff here, as I am new to Oracle). I use OleDBConnection, OleDbCommand and OleDbReaders classes to access Oracle data.

In other words can I have one application running using Oracle Authentication and one app running using Windows Authentication from the same Database? And does that Windows Authentication comes with Oracle 10g enterprise,so I don't need to purchase any special adapters or middleware?
