title: Oracle and Asp.net connection
body: <p>I use Oracle SQL developer and I made a connection to my database with the system user, after I created a user and made a another connection when I try to run I get the SQL Error:</p>
  
  <blockquote>
    <p>"ORA-01747: invalid user.table.column, table.column, or column
    specification"</p>
  </blockquote>
  
  <p>This is my code for insert function:</p>
  
  <pre><code>    Dim sql As String = "INSERT INTO SCHEME(CODE,DESC)" &amp; _
      " VALUES (:CODE,:DESC)"
  
  Dim cmd As New OracleCommand(sql, conn)
  
  cmd.Parameters.Add(New OracleParameter("CODE", txtCODE.Text))
  cmd.Parameters.Add(New OracleParameter("DESC", txtDESC.Text))
  </code></pre>
