How to update XML attribute in clob Oracle using XMLQuery - sql

Question

Oracle table name: SR_DATA;
Table field name: XMLDATA type CLOB;
Field value:
<module xmlns="http://www.mytest.com/2008/FMSchema">
<tmEsObjective modelCodeScheme="A" modelCodeSchemeVersion="01" modelCodeValue="ES_A"></tmEsObjective>
</module>
I need to update the value of the attribute "modelCodeValue" into ES_B.
This is the code:
UPDATE SR_DATA
SET XMLDATA =
XMLQuery('copy $i := $p1 modify
((for $j in $i/module/tmEsObjective/#modelCodeValue
return replace value of node $j with $p2))
)
return $i'
PASSING XMLType(REPLACE(xmldata, 'xmlns="http://www.mytest.com/2008/FMSchema"', '')) AS "p1",
'ES_B' AS "p2"
RETURNING CONTENT);
This code returns the error code: ORA-00932: inconsistent datatypes: expected CLOB got -

Use getclobval() like this:
UPDATE SR_DATA
SET XMLDATA =
XMLTYPE.GETCLOBVAL(XMLQuery('copy $i := $p1 modify
((for $j in $i/module/tmEsObjective/#modelCodeValue
return replace value of node $j with $p2))
return $i'
PASSING XMLType(REPLACE(xmldata, 'xmlns="http://www.mytest.com/2008/FMSchema"', '')) AS "p1",
'ES_B' AS "p2"
RETURNING CONTENT ));
