haces esto con XMLELEMENT etc.
select xmlelement("entity-engine-xml",
xmlagg(
xmlelement(
"myxmlfile",
xmlattributes(empno as "EMPNO",
ename as "ENAME",
to_char(hiredate, 'yyyy-mm-dd') as "HIREDATE",
sal as "SAL",
deptno as "DEPTNO"
)
)
)
).getclobval()
from emp;
.
how to convert xmltype to varchar2 ???
hay un getStringVal
función para esto. es decir, en mi ejemplo anterior usé getClobval . hay un getstringval() equivalente.
