Given below is the relevant data service query.
<query id="StoredprocQuery">
<sql>call getEmployee(?)</sql>
<result element="employees" rowName="employee">
<element name="id" column="id" />
<element name="name" column="name" />
<element name="address" column="address" />
</result>
<param name="empid" sqlType="INTEGER" />
</query>
<operation name="getEmpusingSP">
<call-query href="StoredprocQuery">
<with-param name="id" query-param="empid" />
</call-query>
</operation>
And, here is my SP.
mysql> CREATE PROCEDURE getEmployee(empid INTEGER) select id, name, address
from employee where id=empid;
