I'm not sure what the performance measurments are vs. concat. I've
never had to build a LOB in that way. Are you trying to combine
multiple columns or somthing?

I have not, will this increase the performance? I read that clobs could be
used the same as varchars so I didn't think I would have to.

Thanks,

  Have you tried using the DBMS_LOB.Append function?

  If I have am building an extremely large string (40,000 chars) in a PL/SQL
  stored procedure.  Would it be better to keep concatenating a variable of
a
  CLOB datatype?  Or build 10 varchars and concatenate them at the end into
a
  CLOB?

  I have noticed that my stored procedure runs very slow using the clob. if
I
  use a single varchar(4000) the procedure runs very fast. If I limit the
data
  to 4000 chars and do the same with a clob it runs very slow.

  The way I am doing this is concat(ClobString, 'some more text') over and
  over and over again. Slow....

  Thanks,
