How do I update the result table ?

Question

I am having problem to design and update the competition results in WPC_RESULTS table.
I have 3 tables
1. WPC_COMPETITION - It has details of the competition to be conducted.
2. WPC_MEMBERS - Member details.
3. WPC_RESULTS - Competition results which will have Member_ID, Competition_ID and Status.
In Region 1. I have a drop down list from which I can select the Competition.
Problem is with region 2.
==================
In Region 2. I plan to have All the Member's Name from WPC_MEMBERS, a Status column (W=Win or L=Lost or X=NotPlayed) from WPC_RESULT which can be updated. But the table WPC_RESULTS dosenot have a primary key but has 2 foreign key one from WPC_COMPETITION and one from WPC_MEMBERS.
I am just not able to plan & create this region 2.
Can someone login to my wokspace and give me a helping hand.
Please mail me at [email protected] and I would give you the password for my workspace.

Answer 1

My problem is since the WPC_RESULT table has two master tables. I cannot use a Master Detail form.
What I am trying is,
On a form which displays all the member in WPC_MEMBERS, Drop down list of competition name from WPC_COMPETITION table and a there should be checkbox for status column of WPC_RESULT. So my challenge is to update the WPC_RESULT table with the respective member id and competition id and status in WPC_RESULT table.
As you said I can use a PL/SQL, but I could not understand how do create my PLSQL block to identify each member on the form and update the competition status associated with that member.
in short the table definition is like
CREATE TABLE "WPC_COMPETITION"
(     "COMPETITION_NAME" VARCHAR2(100),
     "COMPETITION_CODE" NUMBER,
     "DATE_CONDUCTED" DATE,
     CONSTRAINT "WPC_PK1" PRIMARY KEY ("COMPETITION_CODE") ENABLE
CREATE TABLE "WPC_COMPETITION"
(     "COMPETITION_NAME" VARCHAR2(100),
     "COMPETITION_CODE" NUMBER,
     "DATE_CONDUCTED" DATE,
     CONSTRAINT "WPC_PK1" PRIMARY KEY ("COMPETITION_CODE") ENABLE
CREATE TABLE "WPC_RESULTS"
(     "COMPETITION_CODE" NUMBER,
     "STATUS" VARCHAR2(1),
     "MEMBER_ID" NUMBER
ALTER TABLE "WPC_RESULTS" ADD CONSTRAINT "WPKD_FK1" FOREIGN KEY ("COMPETITION_CODE")
     REFERENCES "WPC_COMPETITION" ("COMPETITION_CODE") ENABLE
ALTER TABLE "WPC_RESULTS" ADD CONSTRAINT "WPKD_FK2" FOREIGN KEY ("MEMBER_ID")
     REFERENCES "WPC_MEMBERS" ("MEMBER_ID") ENABLE
