Parameterized query in Oracle trouble

Question

I\'m using Oracle.DataAccess rather than the obsolete System.Data.OracleClient and I seem to be having trouble passing multiple parameters to my up

Answer 1

Here's the type of structure I usually use (sorry, this is from memory) :

int rows = 0;
using ( OracleConnection conn = new OracleConnection(connectionString) ) {
  using ( OracleCommand cmd = conn.CreateCommand() ) {
    cmd.CommandText = "UPDATE table SET column1 = ':p1 WHERE column2 = :p2";
    cmd.CommandType = CommandType.Text;
    cmd.Parameters.AddWithValue(":p1", p1Val);
    cmd.Parameters.AddWithValue(":p2", p2Val);
    rows = cmd.ExecuteNonQuery();
  }
}

The key difference is the use of the AddWithValue - I don`t remember why I ended up using that, but do remember having problems with some of the other ways of doing it.
