SQLSyntaxErrorException：預期鍵“ KEY”將出現在“部門”的WHERE子句中

Question

我正在運行從WSO2 DSS到Cassandra數據庫的插入示例。

這是我的帶有Casandra數據庫插入配置的DSS。

<data name="Cdno">
   <config id="insert">
      <property name="url">jdbc:cassandra://localhost:9160/employee</property>
      <property name="driverClassName">org.apache.cassandra.cql.jdbc.CassandraDriver</property>
   </config>
   <query id="Insertinto" useConfig="insert">
      <sql>INSERT INTO employee.dept(eno,dno) values(?,?)</sql>
      <result element="Body" rowName="Datalist">
         <element column="eno" name="eno" xsdType="integer"/>
         <element column="dno" name="dno" xsdType="integer"/>
      </result>
      <param name="eno" ordinal="1" sqlType="INTEGER"/>
      <param name="dno" ordinal="2" sqlType="INTEGER"/>
   </query>
   <operation name="insertinto">
      <call-query href="Insertinto">
         <with-param name="eno" query-param="eno"/>
         <with-param name="dno" query-param="dno"/>
      </call-query>
   </operation>
</data>

當我從DSS插入數據時，嘗試將此服務提供給Cassandra Database，但出現以下錯誤。 我怎樣才能做到這一點。

DS Code: DATABASE_ERROR

Name: Cdno
Location: /Cdno.dbs
Description: N/A
Default Namespace: http://ws.wso2.org/dataservice
Current Request Name: insertinto

當您在卡桑德拉插入數據，你也應該傳遞的關鍵信息。檢查的樣本

Answer 2

WSO2生成無效請求。 除了報告錯誤外，我認為您無能為力。
