Hello,
I use MS SQL Server and I have a table named "MyTable", whose primary key is
a "triple key".
Well, may be that's not the right vocabulary, but I hope you'll see what I
mean:
- The columns in "MyTable" are: "ID1", "ID2", "ID3", "Description".
- Each element in "MyTable" my table is (uniquely) identified by (ID1, ID2,
ID3).
- Each object of the class "MyClass" maps to "MyTable"
- "ID1" is an ID that relates to a java object of the Class "MyClass1"
- "ID2" is an ID that relates to a java object of the Class "MyClass2"
- "ID3" is an ID that relates to a java object of the Class "MyClass3"
The big question is: how do I write the part in the "mapping.xml" file that
describes how "MyClass" maps to "MyTable"?
<class name="MyClass" identity="<??? I dont know !!!>" >
<map-to table="MyTable"/>
<field name="ID1" type="integer">
<sql name="ID1" type="integer" />
</field>
<field name="ID2" type="integer">
<sql name="ID2" type="integer" />
</field>
<field name="ID3" type="integer">
<sql name="ID3" type="integer" />
</field>
<field name="Desc" type="string">
<sql name="Desc" type="char" />
</field>
</class>
Could somebody help ?
Thanks,
Alexandre
