Question

我有以下查询，搜索匹配字符串的xml列请求。

$("#btnSave5").click(function (e) {
            e.preventDefault();
            var form = $(this).closest("form");

            $.ajax({
                type: "POST",
                url: form.attr("Edit"),
                data: form.serialize(),
                success: function (response) {

                    alert("Informations are successfully changed");
                    window.location.href = "/InspekcijskeKontrole/Index";

                },

                error: function (error) {
                    alert(error);
                }

            });
        });

但是我收到select * from Customer where access like '%USR' and status = 'SUCCESS' and request like '%' || (SELECT REGEXP_SUBSTR(request, '<paes:IdName>PurchaseId</paes:IdName><paes:IdValue>\d+</paes:IdValue>') FROM Customer where request like '%Add%SUB%PRIME%') || '%';

的错误消息

我想要的是搜索与添加具有相同ID的请求，但它不是添加请求。例如....取消订单请求，其中包含用于取消订单的ID号。

如何更改上述使用请求，以便ORA-01427: single-row subquery returns more than one row like'％'|| ...... || '％'

或上述查询的替代方案？

in

将返回多行ID

我想要的是搜索匹配ID的所有请求列。如果我将SELECT REGEXP_SUBSTR(request, '<paes:IdName>PurchaseId</paes:IdName><paes:IdValue>\d+</paes:IdValue>') FROM Customer where request like '%Add%SUB%PRIME%'替换为like，我会收到in错误。我该如何解决这个问题？

编辑：示例请求列

ORA-00932: inconsistent datatypes: expected - got CLOB

如果我双击HUGECLOB，我会得到完整的请求，如下所示......

Request
(HUGECLOB)
(HUGECLOB)
(HUGECLOB)
...

因为sopa消息是正常的xml文档。它可以通过更加结构化的方式处理。

准备测试数据库;

create table rr (id number, requext clob) ;

短信息版本。

insert into rr values(1, '<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
    <SOAP-ENV:Body xmlns:paes="emvin.atl/schema/v1">
      <paes:IdName>PurchaseId</paes:IdName>
      <paes:IdValue>2786872</paes:IdValue>
      <paes:IdName>MailAddressId</paes:IdName>
      <paes:IdValue>2786622</paes:IdValue>
    </SOAP-ENV:Body>
    </SOAP-ENV:Envelope>');
insert into rr values(2, '<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
    <SOAP-ENV:Body  xmlns:paes="emvin.atl/schema/v1">
    <paes:IdName>CancelId</paes:IdName>
    <paes:IdValue>2786872</paes:IdValue>
    </SOAP-ENV:Body>
</SOAP-ENV:Envelope>');

使用xmltable函数，我们可以提取paes：IdValue。

select * from rr,xmltable( xmlnamespaces('emvin.atl/schema/v1' as "paes"), '$doc//paes:IdValue' passing xmltype(rr.requext) as "doc" 
columns  IdValue  number path './text()'
) ;

现在，您可以从之前的查询创建视图，或者只在with语句中使用它。

with test as (
select * from rr,xmltable( xmlnamespaces('emvin.atl/schema/v1' as "paes"), '$doc//paes:IdValue' passing xmltype(rr.requext) as "doc" 
columns  IdValue  number path './text()'
)) 
select * from test where IdValue in (select IdValue from test where id =1) 
 and id != 1;

xquery

xmltable

使用Like with In选择查询
