You can set the null attribute to true , so that the tag appears in your XML
see the statement in Bold.
DECLARE
queryCtx dbms_xmlquery.ctxType;
result CLOB;
BEGIN
-- set up the query context
queryCtx := dbms_xmlquery.newContext(
'SELECT empno "EMP_NO"
, ename "NAME"
, deptno "DEPT_NO"
, comm "COMM"
FROM scott.emp
WHERE deptno = :DEPTNO'
dbms_xmlquery.setRowTag(
queryCtx
, 'EMP'
dbms_xmlquery.setRowSetTag(
queryCtx
, 'EMPSET'
DBMS_XMLQUERY.useNullAttributeIndicator(queryCtx,true);
dbms_xmlquery.setBindValue(
queryCtx
, 'DEPTNO'
, 30
result := dbms_xmlquery.getXml(queryCtx);
insert into clobtable values(result);commit;
dbms_xmlquery.closeContext(queryCtx);
END;
select * from clobtable
<?xml version = '1.0'?>
