I am new to Visual Basic.NET.
 I had installed Visual Studio 2010 on my machine. I have Oracle 10g as the database.
I need to connect the front end  Visual Basic to Oracle.

The Login to Oracle is "Scott"
Password is "tiger"
Database is "all_employees"

I have an employee table in  that Oracle database.  Table name := "Employee"
The fields are "Empno", "EmpName","Job_Title", "Salary".

I need to update the salary of all the employees to 5000 whose Job_Title is "CLERK".
Could some one please send me the entire code as to how to achieve that with VB.NET and Oracle.

Do I requre to install any special Oracle ODBC drivers / dll files to connect Oracle to VB.NET?

Thanks

here is connection string for oracle that I use:


Dim cs As String = "Data Source=[Data Source]; User ID=[User ID]; Password=[Password]; Incr Pool Size=[Incr Pool Size]; Decr Pool Size=[Decr Pool Size]; Max Pool Size=[Max Pool Size]; Validate Connection = [Validate Connection]; Connection Timeout=[Connection Timeout]; Connection Lifetime=[Connection Lifetime]; Pooling=[Pooling];"

dim DBConnection As OracleConnection
DBConnection.ConnectionString=cs
DBConnection.Open
Dim cmd As New OracleCommand("select sysdate as OraDate from dual", DBConnection)
cmd.CommandType = CommandType.Text
cmd.ExecuteNonQuery()
DBConnection.Close

Open in new window

I suggest you use ODP.Net from Oracle as your data access provider.  There is sample code and examples on the site:
