RE: Problem with stored procedure and resultMap or resultClass?

Ravi Sundaar Fri, 03 Jun 2005 16:18:26 -0700

My question is fairly simple:

How can I use ibatis to get result sets from a stored procedure that has no "OUT" or "INOUT" parameters?

The stored procedures that I need to invoke take one or more "IN" parameters and generate one or more result sets. They don't have any declared "OUT" or "INOUT" parameters.

Does someone have an example that could help me (and several others)? Or, can you point me in the right direction?

The DBMS I am using is Sybase, if that matters.

Thanks a lot!

Ravi.

am running into a problem accessing result sets from stored procedure using ibatis datamapper.

My DBMS is sybase and driver is Jtds.

Here is the sqlmap:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<!DOCTYPE sqlMap PUBLIC "-//iBATIS.com//DTD SQL Map 2.0//EN" "http://www.ibatis.com/dtd/sql-map-2.dtd">

<sqlMap namespace="PropAssessmentNameSpace">



<resultMap id="propAssessmentResult" class="PropAssessment">
<result property="rptdPropStrAddr" column="RptdPropStrAddr" nullValue=""/>
</resultMap>

<parameterMap id="PropAssessmentParamMap" class="java.util.HashMap" >
<parameter property="casefileId" jdbcType="VARCHAR"
javaType="java.lang.String" mode="IN"/>

</parameterMap>

<procedure id="stpRtrvPropAssessmtId" parameterMap="PropAssessmentParamMap" resultClass="PropAssessment">

{call stpRtrvPropAssessmt (?)}

</procedure>

</sqlMap>
______________________________________________

The code snippet that invokes the procedure is below:

HashMap paramMap = new HashMap();
paramMap.put("@casefileId", "ravi4");
DataSource ds = sqlMap.getDataSource();
sqlMap.setUserConnection(conn);

sqlMap.queryForObject("stpRtrvPropAssessmtId", paramMap);

When I execute the stored procedure in isql mode, with "ravi4" as the input param, it gives me one row as the result set.
