SQL & PL/SQL

Hi,

I am trying to load the XML document into XML Table. Though there exists the Directory loaded with xml file, It's giving an error while inserting into the table.

My Code is as follows,

CREATE TABLE XmlData
(
 KEYVALUE varchar2(10) primary key,
 XMLCOLUMN xmltype
);


CREATE TABLE XMLTABLE OF XMLType;

-- Loaded the File purchaseorder.xml into OS directory "FXLMBAH"

SELECT * FROM All_Directories

What could be the readon causing the error.
