Hi, I have a procedure that accepts a clob as a parameter. When i am using the test windows with a temporary clob variable to pass the parameter in the procedure PSD exhibits the same behaviour as reported by Sachin. In addition when i try to execute the process i get a lpx-00283(document encoding is UTF-8-based but default input is not) error as well. The xml was retrieved from PSD's large data editor following a call to dbms_xmlgen.getxml on the same database. To complicate thing even further if i insert the xml in a db column and select it then the procedure works fine. Can you please look into this? I will send the PSD support infor on a separate email
