Grougby for 1:1 relationship
----------------------------
Key: IBATIS-231
URL: http://issues.apache.org/jira/browse/IBATIS-231
Project: iBatis for Java
Type: Wish
Components: SQL Maps
Environment: Windows
Reporter: Leo Tu
I have two classes, one is Parent(master) another is Child(Detail), but they
are 1:1 relationship,
The question is that in child class contains just one parent object, but i must
use List for getter/setter elsewise
has problem, why ?
===================================================
// parent
public class CustGroup {
...
}
// child
public class Cust {
...
private CustGroup custGroup; // 1:1
...
public void setCustGroupjava.util.List custGroupList) { ... } // why it must
be List data type ?
public java.util.List getCustGroup() { ... } // why it must be List data
type ?
...
}
<resultMap id="CustGroup-result" class="CustGroup">
...
</resultMap>
<resultMap id="CUST-result" class="Cust">
...
<result property="custGroup" resultMap="CUST_GROUP"/> <!-- 1:1 -->
</resultMap>
===================================================
1:1, but groupby must use List for getter/setter,
Can't use
public void setCustGroup(CustGroup custGroup) { ... } // I hope can use
this methd
public CustGroup getCustGroup() { ... } // I hope can use this methd
Best Regards,
Leo
