[Seasar-user:17724] Re: [dbflute-Two Tables]

[kubo]

Hello,

Sorry, it's about time for me to go to bed...
I can not make my reply for several hours.
(until next morning in Japan)
So I'm trying to write what I can write now.


If you want to select MEMBER and MEMBER_STATUS,
(MEMBER and MEMBER_STATUS : many-to-one)
you can implement in condition-bean like this:

/= = = = = = = = = = = = = = = = = = = = = = = = = = = =
MemberCB cb = new MemberCB();
cb.setupSelect_MemberStatus(); // *Point!

List<Member> memberList = memberBhv.selectList(cb);
for (Member member : memberList) {
    // columns of MEMBER table
    Integer memberId = member.getMemberId();
    String memberName = member.getMemberName();

    // columns of MEMBER_STATUS table
    MemberStatus memberStatus = member.getMemberStatus(); // *Point!
    String memberStatusName = memberStatus.getMemberStatusName();
    ...
}

If you want to select MEMBER and PURCHASE,
(MEMBER and PURCHASE : one-to-many)
you can implement in condition-bean like this:

/= = = = = = = = = = = = = = = = = = = = = = = = = = = =
MemberCB cb = new MemberCB();

// At first, it selects the list of Member.
ListResultBean<Member> memberList = memberBhv.selectList(cb);

// And it loads the list of Purchase with its conditions.
memberBhv.loadPurchaseList(memberList, new ConditionBeanSetupper<PurchaseCB>() {
    public void setup(PurchaseCB cb) {
        cb.query().setPurchaseCount_GreaterEqual(2);
        cb.query().addOrderBy_PurchaseCount_Desc();
    }
}); // *Point!

for (Member member : memberList) {
    // columns of MEMBER table
    Integer memberId = member.getMemberId();
    String memberName = member.getMemberName();

    // list of purchase for current member.
    List<Purchase> purchaseList = member.getPurchaseList(); // *Point!
    for (Purchase purchase : purchaseList) {
        // columns of Purchase table
        Integer purchaseId = purchase.getPurchaseId();
        ...
    }
}
