Oracle convert LONG data type to varchar2.

Hi

I need to be able to convert the contents of a LONG field type to text in an SQL select statement.  I have tried converting the contents to XML first, but the query fails if there are any invalid XML characters such as "&" are in the field.

putting it simply, i want to be able to use a statement like

select field1, field2, field3, to_char(long_field) from table_name

Many thanks

The problem with going to varchar2 is you have a limit of 4000 characters.

If you have more than that, you'll need a user defined function that returns a CLOB.  I'm sure those are out there as well.
