Subject Trying to use HashMap as a param object for an UPDATE - getting an exception
Date Tue, 09 Dec 2008 20:29:34 GMT
Hi,
 
I'm trying to execute an update, with a HashMap for parameter (there's no business object
to pass). The mapping file is as follows (iBATIS v.2.3.0.677)
 
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE sqlMap PUBLIC "-//ibatis.apache.org//DTD SQL Map 2.0//EN" "http://ibatis.apache.org/dtd/sql-map-2.dtd">
<sqlMap namespace="Sector">
<resultMap class="java.util.HashMap" id="sector">
	<result property="id" column="SECTOR_ID" javaType="java.lang.Integer" />
	<result property="code" column="SECTOR_CD" />
	<result property="description" column="SECTOR_DESC" />
	<result property="fiscalYear" column="FISCAL_YR" javaType="java.lang.Integer" />
</resultMap>
<parameterMap class="java.util.HashMap" id="sector">
	<parameter property="id" jdbcType="NUMERIC" />
	<parameter property="code" jdbcType="VARCHAR" />
	<parameter property="description" jdbcType="VARCHAR" />
	<parameter property="fiscalYear" jdbcType="NUMERIC" />
</parameterMap>
<select id="getSectorList" resultMap="sector" parameterMap="sector">
	SELECT * FROM SECTOR WHERE FISCAL_YR = #fiscalYear#
	<isNotEmpty property="code">AND SECTOR_CD LIKE #code#||'%'</isNotEmpty>
	<isNotEmpty property="description">AND SECTOR_DESC LIKE #description#||'%'</isNotEmpty>
</select>
<update id="updateSector" parameterMap="sector">
	UPDATE SECTOR SET SECTOR_DESC = #description# WHERE SECTOR_ID = #id#
</update>
</sqlMap>

Both parameters and results are Maps, and the select works when I pass it a parameter map,
whether it has all the properties, or not. Update, however, fails:

Map s1 = new HashMap();
s1.put("code", "001");
s1.put("description", "Region Transaction upd");
s1.put("fiscalYear", "2005");
s1.put("id", "1501");
client.update("updateSector", s1);

Am I doing something wrong?

Thanks,
