Question

美好的一天。

我在“xmltype”类型的变量中有一个xml。有问题的xml是这样的：

，当“EndDate”字段“ValidityPeriod”的日期大于当前日期时，我希望获得“id”节点“Cost Center”字段。

为此，我有以下查询，但不适合我。

FOR r IN (
                SELECT ExtractValue(Value(p),'/OrganisationalAssignment/CostCenter/Id/text()') as CODIGO_CECO,
                       ExtractValue(Value(p),'/OrganisationalAssignment/CostCenter/Name/text()') as DESCRIPCION_CECO        
                  FROM TABLE(XMLSequence(Extract(xrespond,'/WorkAgreementData/OrganisationalAssignment'))) p
                 WHERE TO_DATE(ExtractValue(Value(p),'/OrganisationalAssignment/ValidityPeriod/EndDate/text()'),'RRRR-MM-DD') >= TRUNC(SYSDATE)
        ) LOOP    
            CECOID := r.CODIGO_CECO;
            CECODESCRIPCION := r.DESCRIPCION_CECO;
          END LOOP;

我收到错误，表明节点返回了太多行。

当“validityPeriod”日期大于当前日期时，如何获取id字段“Cost Center”。

Answer 1

extractValue()函数is deprecated anyway;您可以使用XMLTable()从XML中获取多个结果。

根据您发布的值，这个：

FOR r IN (
        SELECT *
        FROM XMLTable('//WorkAgreementData/OrganisationalAssignment/CostCenter'
        PASSING xrespond
        COLUMNS CODIGO_CECO VARCHAR(10) PATH 'Id',
            DESCRIPCION_CECO VARCHAR(50) PATH 'Name',
            START_DATE DATE PATH 'ValidityPeriod/StartDate',
            END_DATE DATE PATH 'ValidityPeriod/EndDate'
        )
        WHERE END_DATE >= TRUNC(SYSDATE)
    ) LOOP    
        CECOID := r.CODIGO_CECO;
        CECODESCRIPCION := r.DESCRIPCION_CECO;

        dbms_output.put_line(CECOID ||' : '|| CECODESCRIPCION
          ||' : '|| r.START_DATE ||' : '|| r.END_DATE);
      END LOOP;

产生

您需要XMLTable列列表中的EndDate，以便您可以将其过滤为使用sysdate;我已经包含了StartDate，只是为了表明你真的可以。如果您需要更多数据，也可以添加其他列。

您还可以使用xs:date()和fn:current-date()在XPath中进行过滤：

FOR r IN (
        SELECT *
        FROM XMLTable('for $i in //WorkAgreementData/OrganisationalAssignment/CostCenter
            where xs:date($i/ValidityPeriod/EndDate) ge fn:current-date()
            return $i'
        PASSING xrespond
        COLUMNS CODIGO_CECO VARCHAR(10) PATH 'Id',
            DESCRIPCION_CECO VARCHAR(50) PATH 'Name'
        )
