Hi,
Sorry if this show up twice - I posted it last week, and haven't yet seen it
show, so here it is again.
I want to be able to do a subselect where the child objects have a specific
position in the parent.
My database has three tables -
Team (the parent)
Player (the child)
TeamPlayer (the relationship between them)
The Team and Player tables each have a primary key, and the TeamPlayer table
has reference to a team, a player, and the squad number of that player in the
team.
Each player can be in one team or no team.
Can I implement this kind of relationship in Ibatis without having to implement
a separate class for the TeamPlayer table?
I'd like to be able to use ibatis to insert the player objects at the right
position in the team object (using squad number as key in a hashmap, say) but
I'm at a loss as to how to build my sqlmap.
Currently I have Java objects:
public interface Team
{
public void setName(String name); //PK
public void getName();
public void getPlayer(int squadNo);
public void setPlayer(int squadNo, Player player)
public HashMap getPlayers();
public void setPlayers(HashMap players);
}
public interface Player
{
public void setName(String name); //PK
public void getName();
}
My Player sqlmap is simple as, just doing a select * from players,
but my Team sqlmap is the one I'm having trouble with.
I wanted to be able to do something like
<resultMap id="teamResult" class="valueobject.newmodel.impl.TeamImpl">
<result property="homeGround" column="home_ground"/>
<result property="name" column="name"/>
<result property="players" select="selectTeamPlayers"
column="name">
</resultMap>
where the selectTeamPlayers select creates a HashMap of Players keyed by squad
number.
Any ideas how I could make it work?
