Well I have been hacking this one to death this weekend. Did manage to get it to work using a SP that creats a lob pointer before we do the update but this is a very bad hack on my part. I think this will require lob locators as the function SYS.XMLType.CREATEXML requires all the CLOB there before it runs, So we might have to
1) prepare the SQL 2) upload the CLOB 3) bind 4) execute the statment. I do not like this myself. I will look at the Lob locators and see if I can work it out with that later this week. cheers All ""John Scoles"" <[EMAIL PROTECTED]> wrote in message news:[EMAIL PROTECTED] > Sorry to be a Johnny come lately on this (pun intended) > > I have been playing with this myself and like you chaps have come up with > a blank.
