FK on a column to a table where the column is not the PK but a Unique Index

Hello everyone, I am new to ERWIN and I need helps from the experts out
there.

We are using ERWin 4.1.2771 and have reversed engineered some MS SQL
Server 2000 databases.

The problem we are having is that we have a FK on a column to a table
where the PK of the referencing table is on another column (such as an
identity column). We have a unique index on the column in the PK table
and SQL Server allows you to build a FK reference even though the
column is not defined as the PK.

Does anyone know how to create this type of FK within Erwin?

Thank YouStandard SQL allows you to reference any UNIQUE() constraint from a
FOREIGN KEY. Indexes do not exist in Standard SQL, so be sure to use
the UNIQUE() constraint.|||Use a unique constraint rather than a unique index.

First 5 Related Records?

I am trying to determine what the first 5 related records to another record
are. I have created a table of matches where I have returned the unique key
value for each record in a one to many relationship. Preferrably, I would
like to update the table that contains the F_rel_num with the 5 (or less)
values for RE_rel_num in fields such as RE_rel_num1,
RE_rel_num2...RE_rel_num5. The top 5 is based on decending values for
RE_rel_num. I have included sample data below. TOP 5 in hte SELECT would not
work as I need the top 5 for each F_rel_num. Does anyone know how to do this
?
I could easily write this in ASP or VB, but I need to be able to run this as
a regular SQL job, so I imagine I need to do it completely with T-SQL.
