I need to store and retrieve data into a AL32UTF8 database without losing language attributed.
I am using DBMS_XMLDOM.getnodevalue (); to fetch the XML stored in a CLOB column
But the package returns VARCHAR2 .How do i return NVARCHAR2 so that i can store Multilingual data
DBMS_XMLDOM.GETNODEVALUE(
n IN DOMNode)
RETURN VARCHAR2;
Or is there an easier way around using XMLTYPE
