Answer 1

Assuming salary amount is 20000, You can try this code:

var commandText = "insert into Emp_table (SL_NO,empane,empid,salaray) values(:SL_NO,:empane,:empid,:salary)";

using (OracleConnection connection = new OracleConnection(connectionString))
using (OracleCommand command = new OracleCommand(commandText, connection))
{
    command.Parameters.AddWithValue("SL_NO", 1);
    command.Parameters.AddWithValue("empane", "sree");
    command.Parameters.AddWithValue("empid", 1002);
    command.Parameters.AddWithValue("salaray", 20000);
    command.Connection.Open();
    command.ExecuteNonQuery();
    command.Connection.Close();
}

Microsoft deprecated their Oracle provider (System.Data.OracleClient) so use a third party provider such as Oracle's Data Provider for .NET. The code example below is essentially the same as FSX's answer, just without the convenience of the AddWithValue method.

command.Parameters.Add(new OracleParameter("SL_NO", 1));
command.Parameters.Add(new OracleParameter("empane", "sree"));
