Why Do I get OutOfRange Exception in GetOrdinal Function of this CLOB field?

Question

This is the sample of my code. The field FUNCTION_SCRIPT is a CLOB field (the only CLOB field) in my table IS_FUNCTION

public void ReadFunction(string FName         


        

Answer 1

Thanks for all the suggestions and helps. I found that my problem was resolved by adding a

 if(odr.Read())
            {
                int temp = odr.GetOrdinal("FUNCTION_SCRIPT");
                OracleLob myLob = odr.GetOracleLob(temp);
                fContent = (String)myLob.Value;
            }

In other words, I was missing the statement odr.Read after the ExecuteReader() statement.
