the problem is that I want to (SQL) select from a table in an Oracle database, and show the results of the query in the VB application, in a Excel like manner (rows, columns, selectable, etc.). Or in a SQL developer manner. Haw can I do that? Browsed through a lot of tutorials and howtos on the internet, did not get anywhere.
View 2 RepliesI'm converting some RDO code to ODBC Provider code in .NET.The problem is parameter names were not specified in the orignal code, but param values were retrieved by parameter name after the command was executed.Is there anyway to have parameter names populated by the provider once the command is executed so calling code can access params by name.Let me show you an example of the declaration of param and accessing of it.
[Code]...
You can now see how this "used to work in RDO/VB". For some reason it would accept this and know what the param names were after execution. I imagine it had to do another round trip to the db to get this info.
Is there anyway to mimic this behaviour in .NET for ODBC Provider (using Oracle)? Or am I stuck manually specifying the param names in the code (I understand this is the better option, but wondering what the alternative is to match the original code as closely as possible).
I have the below mentioned code in a seperate class file for establishing connection and carry out DB transactions. I have an issue where multiple connections being opened which sometime exceed the connection pool. When I stepped through the code I found that there are codes which call ConnectDB() in a loop without calling DisconnectDB(). But I expected that the condition OraConn.State = ConnectionState.Closed should handle the situation. Somehow the condition is always satisfied hence openning another set of connection. Can you suggest where am I going wrong and also what best practice can be adopted here?
[Code]...
The connection is again opened in function updData(). While I understand that it has to be closed correctly but keeping tab on every developer is not possible. Hence I want to control it directly from the connection class by using the same connection but the condition If OraConn.State = ConnectionState.
UPDATE I have put the code in UpdateDB under a Using block and removed call to ConnectDB and DisconnectDB from function like InsertData(...). It seems that the issue has been resolved. But I would like to know in case of exception will the connection remain open? and also OraConn is a public variable defined outside Using block so will it be disposed of by the GC?

I recently upgraded my system to Windows 7 64bit and ever since then I have had nothing but issues with my code attempting to access an Oracle database. I was using msdaora for my connection string however that does not work in 64bit. I changed over to OraOLEDB.Oracle which everything I can find on Google says to use however it fails every time. I have installed Oracle 11g 2 times now and even tried reinstalling VB.net 2010 and still no luck.
Here is my connection string....
Code:
MyConn.ConnectionString = "Provider=OraOLEDB.Oracle;Server=emsp.grhq.XXXX.com;Data Source=emsp;User Id=XXXX;password=XXXX"
And I am inporting....
Code:
Imports System.Data.OracleClient
Yet when I try it says...

I have two small VB.NET applications that connect to the same Oracle database. One uses the OLEDB provider, and the other uses Oracle's ODP.NET. Should I expect to see problems with the OLEDB provider, as it's less 'native' to Oracle?

View 4 RepliesI'm having a few problems with connection strings. I'm trying to connect to a sql 2005 express database. If I use the following connection string [code] Then I can succesfully connect to the database. However a problem is caused by this connection string when i attempt to work with stored procedures. I keep getting an error message. I am told that "OleDb Provider for SQL Compact only implments a forward only cursor, so using it with Datasets are out of the question... " . Is this true ? I think the reason sql connection string doesn't work is because the northwind database is on one (different) drive, and the sql server and Vb software is on another drive. I think the reason the oledb connection string is working because I specify the exact location/address of the northwind database. Does any one know how I can get the sql connection string to work?
