我在尝试在wso2 dss上测试数据服务时遇到此错误
DS错误消息:错误输入 'SQLQuery.processStoredProcQuery'DS代码:DATABASE_ERRORSource数据 服务:-Name:CustomerDSLocation:\ CustomerDS-1.0.0.dbsDescription: N / ADefault命名空间:http://ws.wso2.org/dataserviceCurrent请求 名称:op1Current Params:{Name =?,NID =?}嵌套异常:-DS Fault 消息:'createProcessedPreparedStatement'DS代码中的错误: UNKNOWN_ERRORNested异常:-java.sql.SQLException:参数索引 3的范围超出范围(1,0)
有什么建议吗?
编辑:bds文件如下,这是wso2文档中提到的示例案例。
<data name="CustomerDS">
<config id="default">
<property name="org.wso2.ws.dataservice.driver">com.mysql.jdbc.Driver</property>
<property name="org.wso2.ws.dataservice.protocol">jdbc:mysql://localhost:3306/CustomersDatabase</property>
<property name="org.wso2.ws.dataservice.user">root</property>

<query id="q1" useConfig="default">

<result element="Entries" rowName="Entry">

<element name="Customer" column="Customer" xsdType="xs:string" optional="true" />
</result>
<param name="NID" sqlType="STRING" ordinal="1" />
<param name="Name" sqlType="STRING" ordinal="2" />
<param name="Flag" sqlType="INTEGER" type="OUT" ordinal="3" />
<param name="Customer" sqlType="STRING" type="OUT" ordinal="4" />
</query>
<operation name="op1">
<call-query href="q1">
<with-param name="NID" query-param="NID" />
<with-param name="Name" query-param="Name" />
</call-query>
</operation>
</data>
为我做了什么!!
我在http://svn.wso2.org/repos/wso2/people/kasun/wso2con_2013/starbucks_2.0/dss/StarbucksDataService.dbs
找到了参考代码和最终为我工作的程序调用是(程序本身改变)
<data name="CustomerDS">
<config id="default">
<property name="org.wso2.ws.dataservice.driver">com.mysql.jdbc.Driver</property>
<property name="org.wso2.ws.dataservice.protocol">jdbc:mysql://localhost:3306/CustomersDatabase</property>
<property name="org.wso2.ws.dataservice.user">root</property>
<property name="org.wso2.ws.dataservice.password">root</property>
</config>
<query id="q1" useConfig="default">
<sql>call getCustomer(?,?)</sql>
<result element="Entries" rowName="Entry">
<element name="Flag" column="Flag" xsdType="xs:integer" optional="true" />
<element name="Customer" column="Customer" xsdType="xs:string" optional="true" />
</result>
<param name="NID" sqlType="STRING" ordinal="1" />
<param name="Name" sqlType="STRING" ordinal="2" />
<param name="Flag" sqlType="INTEGER" type="OUT" ordinal="3" />
<param name="Customer" sqlType="STRING" type="OUT" ordinal="4" />
</query>
<operation name="op1">
<call-query href="q1">
<with-param name="NID" query-param="NID" />
<with-param name="Name" query-param="Name" />
</call-query>
</operation>
</data>
现在暂定的工作程序是:
DELIMITER //
CREATE procedure getCustomer(NID varchar(200),Name varchar(200))
BEGIN
DECLARE id varchar(200);
DECLARE flag int;
SET Flag = 0;
SET id = CONCAT(NID, '_' , Name);
INSERT INTO Customer(NID, Name, customerID) VALUES(NID, Name, id);
select flag, customerid from customer where customerID = id;
END//
