Sql Oracle XMLQuery传递参数值,sql,xml,oracle,Sql,Xml,Oracle,在我的XMLQuery中需要帮助获取循环序列 SELECT extractvalue(update_xmldoc, 'count(/invoice/AR_ITEMS/ITEMS[NAME="Voice" and ITEM_TOTAL!=0])') INTO item_check FROM xml_billrun_files WHERE seq_id = seq AND docname = REPLACE(fn,'.','_HULK.') ORDER BY

在我的XMLQuery中需要帮助

获取循环序列

SELECT extractvalue(update_xmldoc, 'count(/invoice/AR_ITEMS/ITEMS[NAME="Voice" and ITEM_TOTAL!=0])')
    INTO item_check
    FROM xml_billrun_files
    WHERE seq_id = seq
    AND docname  = REPLACE(fn,'.','_HULK.')
  ORDER BY TIMESTAMP DESC;

然后项检查值将传递给循环

FOR lp IN 1..item_check LOOP
      SELECT tst, bill_info_id, bill_no, dur_net_amt, dur_vat_amt, dur_pro_net_amt, dur_pro_vat_amt, sys_descr
      INTO xmlU, bp, bill, net_amt1, vat_amt1, net_amt2, vat_amt2, disc_name
      FROM
        (SELECT row_number() over (partition BY t.docname order by t.timestamp DESC) rn,
          t.docname,
          XMLQuery('for $i in distinct-values(/invoice/AR_ITEMS['||lp||']/ITEMS/EVENTS/BAL_IMPACTS/DISCOUNT_INFO)
                    where $i = "Plan499 Corp Disc" 
                    or $i = "Plan899 Corp Disc" 
                    or $i = "Plan1099 Corp Disc" 
                    or $i = "Plan1599 Corp Disc"
                    return $i' passing original_xmldoc returning content ).getStringVal() sys_descr

脚本很好，但是当我在XMLQuery中传递lp的值时，我得到了错误

错误（528,66）：PL/SQL:ORA-19109:应返回关键字

您可以通过passing
子句将PL/SQLlp
变量的值传入，该子句允许多个逗号分隔的参数；为它指定一个标识符，然后直接在XPath中引用它。我一直使用lp
和$lp
；它们不必匹配PL/SQL变量名，但如果匹配，可能会更清楚
      XMLQuery('for $i in distinct-values(/invoice/AR_ITEMS[$lp]/ITEMS/EVENTS/BAL_IMPACTS/DISCOUNT_INFO)

PL/SQL循环索引变量lp
是一个pls_integer
，passing子句不喜欢它；如果你直接传递它，你会得到ORA-00932，因此你需要将它转换为数字数据类型。
如果你不分享整个内容，那么任何人都很难帮助你。理想情况下，你应该给出一个小的工作示例，而不是hat单独演示了这个问题，我们不需要了解域。完成后，我更新了我的问题：）我这样做了，在传递FOR语句中得到的lp值时，它返回错误（535,57）：PL/SQL:ORA-00932：不一致的数据类型：预期-获得本机整数
@NelzKi-我添加了xmltype（lp）
打电话。您能在问题中添加一个示例XML文档吗？用一些数据进行测试会更容易。也可能会建议您正在使用的不推荐使用的函数的替代方案；现在实际使用该值。
