Granted I'm not sure what I'm doing but, Isn't this backwards? Table 'Customer' should be the parent and 'CustomerGroup' should be the child. I thought the FK should be on the child table of CustomerGroup.

Subject: Re: setting up a foreign key
Using this as a start:
CREATE OR REPLACE TABLE rob.CustomerGroup( CompanyId INTEGER NOT NULL, GroupId Integer not null, GroupDescription VARCHAR(100) ALLOCATE(20), primary key (CompanyId, GroupId));
CREATE OR REPLACE TABLE rob.Customer(
CompanyId INTEGER NOT NULL,
Account# Integer not null,
GroupId Integer not null,
primary key (CompanyId, Account#));
I tried to go into
http://myibmi:2001 and use the GUI in there to select multiple keys. I cannot get some of the checking to work. It doesn't seem to respond to my clicking on it.
Since it's not my problem I won't open a pmr on it but I recommend you do so.
A work around is to use Run SQL scripts and try this:
alter table rob.Customer
add foreign key(CompanyId, GroupId)
references rob.CustomerGroup (CompanyId, GroupId) on delete no action on update no action ;
BCCing you an image which the list will strip off.

Subject: setting up a foreign key
Sent by: "MIDRANGE-L" <midrange-l-bounces@xxxxxxxxxxxx>
I am attempting to setup a foreign key using System I Navigator. I've
never created a foreign key before.
Here is my question and I did my best to explain it. I am very new to
all of this.
Customer table with columns.
CompanyID
Account#
Customergroup
Primary/unique key on customer table is CompanyID, Account#
CustomerGroup table with columns.
CompanyIDgrp
GroupID
GroupDescription
Primary/unique key on CustomerGroup table is CompanyIDgrp, GroupID
I need to setup a foreign key.
Does the Customer table need to have an index that has Customergroup as
part of the key in order for me to setup a foreign key? I cannot figure
out how to choose from the Customer Table, Customergroup.
Thanks for any help.
