Multiple Database / Cross Database Referencial Integrity (foreign keys)
Using SQL Server Express 2005, I have two databases. AppDB - The main application database.GeoDB - A somewhat static ZIP code / states / other geographic stuff databaseI need to have some foreign key columns in tables in AppDB reference columns in the GeoDB database tables. Eventually other application database besides AppDB will be doing the same thing in our infrastructure. After googling and reading for days, here is what I

I am working on a program we bought. The previous developpers used PowerAMC
and I can't find where they precised the way to name foreign keys.
Exemple : if the table "Bill" has a reference to the table "Supplier", when
I generate the MPD, the reference is converted this way in the table BILL :
I want to know where "ID_%TABLE%" is defined ?
Otherwise, is it possible for certain foreign keys to define in the MCD the
name they will have in the MPD ? Exemple : I have an other table where I
want one foreign_key to have a special n...Foreign Key Names
I can't seem to figure out where to set the Foreign Key Naming convention.
As I generate from a CDM to PDM how do I take control of how relationships
are migrated and named. and, what documentation should I read to get a
better handle on this?
OK, you do not have any control over the default foreign key names in the
initial CDM -> PDM generation. However, after you change it in the PDM, the
next time you generate PD will abide by your names.

So here is the deal:
I have two database with referential integrity between them. I loaded
one of them from an earlier version of the database and now I have
tables that say a foreign key is referencing them, but that foreign key
really doesn't exist in the other database. Is there a way I can get rid
of this in my production system considering all the copies of my
database have this problem.

I am using PD 11 . The scenario is:
when I create two relations between 2 tables (one with role name and the
other without role name) then generate the physical model, and use the
%PROLE% as FK column name .
when the model generates , one FK gest the role name and the others that
gest the table name as FK. I want to change the default of tabel name to

The default behavior is for the parent table column name to be used as
the FK column. The columns from the first reference should be the

Our application is a message board and is full of messages, threads, and
forums. A message is an individual entry (like the one I'm typing now ;)).
Our software gives the user the ability to upload a single file attachment
to each message.
I can think of a couple different ways to design the two tables:
message( messageid numeric identity, attachmentid numeric null, messagetext
text, other, message, stuff... )
attachment( attachmentid numeric identity, title varchar, other, stuff )
message( messageid, messagetext text, other, stuff )

Table A B C
Column a pk a pk a fk1, fk2
aa b c
aaa c d
A and C are linked by reference D.
B and C are linked by reference E.
I can see that fk1, fk2 are displayed in C table.
I hope that fk is only displayed in C table.
I am not sure I understand what you need to see. When you fold a foreign
key like you have with column a in table C, it is important to know it is a

When I have relationships between two tables, I cannot
influence the name of the foreign key field which is generated.
I have two tables: customer, user
I have two user references in the customer table, the user who manages the
and the user who created the customer record. When I generate the PDM I
get the field names "id_user" and "id_user2" which are not really useful. I
"managing_user" and "creation_user".
Is there a way to influence these names?

So I'm a complete noob to Dynamic Data. My team set up a Dynamic Data website which we're essentially using for scaffolding...we have an already existing DB schema which we plugged it into. And it works perfectly! One thing though - the Dynamic Data code automatically infers a friendly name when generating a drop down list for a foreign key. In our case, we have a "Contacts" table, and the primary key is ContactID, and the first field in the table is "First_Name", and this is what is showing up in the drop down menu. So for instance, when adding or editing an...RoleId/Name as Foreign Key
I'm trying to create a relational SQL data table where one of the foreign keys relates to the aspnet_Roles table.At first, I was linking to the RoleId field because it was the primary key, but that's no good because I can't retrieve the RoleId of a RoleName from my code.
I then read this post:http://forums.asp.net/p/1077364/1585594.aspx#1585594
How do I reference the RoleName field as a foreign key? I tried doing it but because RoleName isn't a Primary Key or 'Unique', it won't let me do it.I get the following message:'The columns in table 'aspnet_R...Cross Database Foreign Key
Does anyone know if SQL Server 2005 or 2008 allows Cross Database Foreign Key Constraint? If not, is there a recommended way to implement this?
I don't know about Cross Database Foreign Key as of SQL Server 2005 i don't abt 2008.

I like to have all my foreign key names set to FK_%PARENT%_%CHILD% so that I
have an idea of what the link is. When I set this up in Rebuild Indexes, I
get sporadic parent and child table names.
For example, I have 3 tables Template, Customer & Store. When I set up an
FK between Template (child) and Customer (parent) I get FK_CUSTOMER_STORE.
Sure enough there is an FK between Customer & Store but why is it being

I wanted to know if there is a way to control the naming convention of
foreign keys in power designer, while generating a PDM from CDM.
You can change this in the DEF file for the target database you are
selecting. Find the file and open it in an editor. You should find a block
that looks like this:
# Constraint name template for Primary Keys
PKConstraintName = PK_%.U27:TABLE%
# Constraint name template for Foreign Keys
FKConstraintName = FK_%.U8:CHILD%_%.U9:REFR%_%.U8:PARENT%
# Constraint name template for Alternate Keys

When generating the physical data model, DA will rename a column which has
a foreign key (so that the column name is the same as the foreign key
column name). Is there a way to disable this ?
