Let me start by saying that I don't have the book, and I don't understand
your question..
Anyway I like the 'feature' of IBATIS that I can map a join query to objects
and child objects using 'dot notation'
Example;
I've got a domain class called Declaration, in it is a other domain class
with the name employee of the type EmplMain,
This must be mapped to table Declaration joined to table EmplMain
Step 1;
Create the empty employee domain object in the declaration class
public Declaration() {
employee = new EmpName();
}
Step 2;
The sql map. Beware of case sensitivity and the fact that even when you
select something like EmplMain.NickName the result column is most likely to
be just NickName.
Therefore you would have to select it like EmplMain.NickName as
'EmplMain.NickName'
<typeAlias alias="declaration" type="com.pastel.ess.domain.Declaration"/>
<statement id="getDeclaration" resultClass="declaration" >
SELECT Declaration.*,
EmplMain.EmplName as 'employee.emplName', EmplMain.Surname as
'employee.surname',
EmplMain.NickName as 'employee.nickName', EmplMain.Code as
'employee.code',
EmplMain.Email as 'employee.email', ..
FROM Declaration ..

Hi all
i'm new to Ibatis and i'm reading "Ibatis in action" Book but i've a No
statetement problem...
so i've these files:
sqlMapConfig.xml
---
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE sqlMapConfig PUBLIC "-//ibatis.apache.org//DTD SQL Map Config
2.0//EN" "http://ibatis.apache.org/dtd/sql-map-config-2.dtd ">
<sqlMapConfig>
<properties resource="com/magoscuro/ibatis/dati.properties"/>
<transactionManager type="JDBC" >
<dataSource type="SIMPLE">
<property name="JDBC.Driver" value="${driver}"/>
<property name="JDBC.ConnectionURL" value="${url}"/>
<property name=" JDBC.Username" value="${user}"/>
<property name="JDBC.Password" value="${password}"/>
</dataSource>
</transactionManager>
<sqlMap resource="com/magoscuro/ibatis/SqlMap.xml" />
</sqlMapConfig>
---
SqlMap.xml
---
<?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>
<select id="getAllAccountIdValue" resultClass="int">
select count(USERID) from USER_ACCOUNT
</select>
<select id="getAllUsers" parameterClass="string" resultClass="hashmap">
SELECT * FROM USER_ACCOUNT WHERE GROUPNAME = #groupName#
</select>
</sqlMap>
---
and finally my java file:
---
public static void main(String[] args) throws Exception {
String resource = "com/magoscuro/ibatis/SqlMapConfig.xml";
Reader reader = Resources.getResourceAsReader(resource);
SqlMapClient sqlMap =
SqlMapClientBuilder.buildSqlMapClient(reader);
List list = sqlMap.queryForList("getAllUsers","EMPLOYEE");
System.out.println("Selected " + list.size() + " records");
for (int i=0; i<list.size(); i++){
System.out.println(list.get(i));
}
}
---
Ok it work very well but i've read in the book that i can use dot
notation, for example Account.gettAllUsers ok now is the problem...how
can i use this dot notation? :D
thank in advance
