Bill,

I agree with Michael. You've already got the data in a "suitable datatype". Why move it to a cumbersome, soon-to-be-obsolete datatype? You can use DBMS_LOB functionality on LOBs, not on Raw.

I'd be so happy if the couple dozen tables in our 3rd party Student Information system that have Long or Long Raw columns had CLOB or BLOB columns instead. It would make converting them to partitioned tables much easier.

I definitely vote to keep your CLOBs.

      Here's where I get to ask the most likely simple question.

      I've inherited a database where it was built using a CLOB to hold XML
      data
      but we have now determined that was total overkill and want to move
      it to a
      RAW column or other suitable datatype.

      Looking for conversion issues or other alternatives.

Since Oracle is moving us away from LONG and RAW datatypes, I assume you want to convert from CLOB to BLOB? BLOB is probably more storage-efficient,
but since XML is made up of character data, I don't really understand the issue with
keeping it a CLOB.

What do you mean by overkill?
