我正在使用 Sybase 中的存储过程创建 WSO2 数据服务。每当我为局部变量赋值时都会出错。

存储过程如下...声明@user_id INT select @user_id =333
....

上面的 select 语句似乎引起了问题并导致了以下错误

DS Code: DATABASE_ERROR Nested Exception:- javax.xml.stream.XMLStreamException: DS Fault Message: Error in 'SQLQuery.processStoredProcQuery': The method com.sybase.jdbc3.jdbc.SybCallableStatement.getMoreResults(int) has not been completed and should not be called. DS Code: DATABASE_ERROR Source Data Service:- Name: testAmit Location: \testAmit.dbs Description: N/A Default Namespace: http://ws.wso2.org/dataservice Current Request Name: amitTestOps Current Params: {invId=22} Nested Exception:- com.sybase.jdbc3.utils.UnimplementedOperationException: The method com.sybase.jdbc3.jdbc.SybCallableStatement.getMoreResults(int) has not been completed and should not be called.  </soapenv:Text>

如果我评论 select 语句，它工作正常。

我的数据服务看起来像这样

<data name="testAmit" transports="http https local">
   <config enableOData="false" id="sybaseAmit">
      <property name="driverClassName">com.sybase.jdbc3.jdbc.SybDriver</property>
      <property ***db config deatils which I have omitted ***</property>
   </config>
   <query id="amitquery" useConfig="sybaseAmit">
      <sql>exec sp_createCorrespondence ?</sql>
      <result element="correspondences" rowName="correspondence">
         <element column="correspondence_id" name="correspondenceIdValue" xsdType="integer"/>
      </result>
      <param name="invId" sqlType="INTEGER"/>
   </query>
   <operation name="amitTestOps">
      <call-query href="amitquery">
         <with-param name="invId" query-param="invId"/>
      </call-query>
   </operation>
</data>

任何帮助将不胜感激！（使用 WSO EI 版本 6.1.1、jconn3.jar、sybase ASE 15.7）
