XML File size changed

Question

Hi, All:
I wondering why the XML file size changed after go through DB using CLOB. The original size is 1KB, but after I use the PUT and GET method, the size changed to 8KB. There is a lot of space appened to the content.
Thanks a lot!

Answer 1

Can you provide an example of the code you are using for the put / get method. In SQL*PLUS I do not see what you are talking about
