title: Oracle NUMBER(20) corresponding c# type?
body: <p>What is the corresponding C# type for an Oracle NUMBER(20)?  Oracle version is 8.</p>
  
  <p>Update:</p>
  
  <p>This is insert query. Then try adding the following parameter to command:</p>
  
  <pre><code>IDbDataParameter idParameter = cmd.CreateParameter();
  idParameter.DbType = DbType.Int64;
  idParameter.Value = id;
  cmd.Parameters.Add(idParameter);
  </code></pre>
  
  <p>Oracle gives me exception: 
  System.Data.Odbc.OdbcException: ERROR [22007] [Microsoft][ODBC driver for Oracle][Oracle]ORA-01840: input value not long enough for date format</p>
