Question

The last time I used Oracle was when 8i was just coming out so I have pretty much forgotten everything I may have know about Oracle, much less what is still relevant. In all these years I have been using MS SQL Server. I want to quickly serialize a result set in to XML. Where might I discover if there is an equivalent Oracle 11g construct as the SQL Server FOR XML AUTO?

Answer 1

a quick way is DBMS_XMLGEN.

SQL> select dbms_xmlgen.getxml('select * from emp where rownum <= 2') xmlstr from dual;

XMLSTR
