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.

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

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

I'm using SQL Any50, ORACLE, and SQL Server 6.5 with a PB 6.0 Application.
I'm looking for a solution to get the name of the Foreign Key, for some
of my application.
Is there someone who know where i can find it in the system table ?
In Oracle, you need to look at either the ALL_CONSTRAINTS or the
In SQL Server 6.5, you would look at the SYSREFERENCES table.
I'm not sure where you'd look in SQL Anywhere.

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 )

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
OK, are you wanting to control the names of indexes or foreign key

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?
Neudorfstr...Foreign Key Inferred Name
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...Foreign Key names #3
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
AK...DA and foreign key names
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 ?

i want to use the ASP.NET 2.0 Membership and Profile Features in my Application but want to store the Data in a different Table.
What field in Security table can i use as a foreign key in my custom created table?
Do you think i should use the username as it is unique?
Usually, we use UserID as the foreign key rather than UserName.

I hope that fk is only displayed in C table.

Is it ok for two tables to have foreign keys to each other based on the same
columns? If so, are there rules about the cascade settings in such a case? I
am thinking of tables that are virtually one-to-one with each other and can
tend to be viewed or deleted equally "from either end".
The first problem I see with this is that it is a "which came first, the
chicken or the egg" type of a problem.
When you insert into one table the FK is going to want to check to see if
the value is in the other...
