IIB/Esql如何将XMLTYPE从oracle表传播到OutputRoot.XMLNSC

我有一个带有计算节点和MQOutput节点的消息流，如下所示：

MQInput->Compute->MQOutput

declare xmlDoc row;
set xmlDoc.rows[] = passthru('select XMLTYPE.getClobVal(xml_document) as xml from my_table where something=something');

    FOR xml AS xmlDoc.rows[] DO
        CREATE LASTCHILD OF OutputRoot DOMAIN('XMLNSC')
                                    PARSE(CAST(xml.XML AS BLOB CCSID InputProperties.CodedCharSetId ENCODING InputProperties.Encoding), 
                                    InputProperties.Encoding,
                                    InputProperties.CodedCharSetId);    

        PROPAGATE;
    END FOR;
    RETURN FALSE;

在compute节点中，我从oracle数据库检索xml文档数组，如下所示：

MQInput->Compute->MQOutput

declare xmlDoc row;
set xmlDoc.rows[] = passthru('select XMLTYPE.getClobVal(xml_document) as xml from my_table where something=something');

    FOR xml AS xmlDoc.rows[] DO
        CREATE LASTCHILD OF OutputRoot DOMAIN('XMLNSC')
                                    PARSE(CAST(xml.XML AS BLOB CCSID InputProperties.CodedCharSetId ENCODING InputProperties.Encoding), 
                                    InputProperties.Encoding,
                                    InputProperties.CodedCharSetId);    

        PROPAGATE;
    END FOR;
    RETURN FALSE;

我验证了这是否正常工作，然后尝试将XML放入MQOutput节点，如下所示：

MQInput->Compute->MQOutput

declare xmlDoc row;
set xmlDoc.rows[] = passthru('select XMLTYPE.getClobVal(xml_document) as xml from my_table where something=something');

    FOR xml AS xmlDoc.rows[] DO
        CREATE LASTCHILD OF OutputRoot DOMAIN('XMLNSC')
                                    PARSE(CAST(xml.XML AS BLOB CCSID InputProperties.CodedCharSetId ENCODING InputProperties.Encoding), 
                                    InputProperties.Encoding,
                                    InputProperties.CodedCharSetId);    

        PROPAGATE;
    END FOR;
    RETURN FALSE;

流运行时没有错误，但输出队列中没有任何内容。我正在寻找一些关于从oracle数据库获取XMLTYPE并将其放入MQOutput节点的正确方法的指导

谢谢

我成功地将SQL查询更改为使用

getBlobVal

新的SQL查询：

set xmlDoc.rows[] = passthru('select mt.xml_document.getBlobVal('UTF8') as xml from my_table mt where something=something');
