wso2 - WSO2 数据服务不适用于命名查询（准备语句）

Question

我只是想在 Oracle XE DB 上做一个连接到 HR 模式的简单数据服务。我刚刚写了一个简单的查询，它接受一个输入参数并根据传递的绑定数据相应地获取结果。

我的查询如下所示

SELECT first_name,last_name,email,phone_number,hire_date,salary 
FROM employees 
WHERE first_name like :Bind_name

我添加了一个输入变量 Bind_name 并在我请求服务时传递它。

但是，当我触发该服务时，我看到以下错误并且在网络上找不到相关帮助。

在这里找到我使用的 .dbs 文件，

<data name="DDD">   
<config id="ds1">      
  <property name="org.wso2.ws.dataservice.driver">oracle.jdbc.driver.OracleDriver</property>      
  <property name="org.wso2.ws.dataservice.protocol">jdbc:oracle:thin:@localhost:1521/xe</property>      
  <property name="org.wso2.ws.dataservice.user">xxx</property>      
  <property name="org.wso2.ws.dataservice.password">xxx</property>
</config>   
<query id="q1" useConfig="ds1">      
  <sql>select EMPLOYEENUMBER  from employees where LASTNAME like :Bind_name</sql>      
  <result element="Entries" rowName="Entry">         
     <element name="EMPLOYEENUMBER" column="EMPLOYEENUMBER" xsdType="xs:string" />      
  </result>      
<param name="Bind_name" sqlType="STRING" />   
</query>   
<operation name="op1">      
  <call-query href="q1">         
     <with-param name="Bind_name" query-param="Bind_name" />      
  </call-query>   
</operation>
</data>

要求是，

<p:op1 xmlns:p="http://ws.wso2.org/dataservice">
  <!--Exactly 1 occurrence-->
  <p:Bind_name>d%</p:Bind_name>
</p:op1>

它按预期工作正常。您也可以发布您的 dbs 文件吗？
