VS 2005 + Sdf + Foreign Key

Mar 13, 2006

Hi



How do you add foreign keys in VS 2005 to a sdf file? I'm using
the server explorer, where I can add primary keys but no foreign keys.



What's the best free tool for editing sdf files? I can't use
publication, because I'm using SQL Express. Primework's DataPort
Component/Wizard don't seem to work for me.



Thanks!

Sql 2005 Foreign Key Error

Jul 4, 2006

Lets say that I have a 3 tables: 1) Sku, 2) ReceiptDetail and 3) OrderDetail. In the last 2, is a Sku column which needs to refer to the Sku table. I create ForeignKeys in the ReceiptDetail & OrderDetail pointing to the Sku table as follows:
Alter Table ReceiptDetail Add Constraint fk_ReceiptDetail_SkuKey Foreign Key (SkuKey) References Sku (SkuKey) On Update Cascade On Delete No Action;
The first 'Alter' (for ReceiptDetail) works, but the second gives me the following message:
Introducing FOREIGN KEY constraint 'fk_OrderDetail_SkuKey' on table 'OrderDetail' may cause cycles or multiple cascade paths. Specify ON DELETE NO ACTION or ON UPDATE NO ACTION, or modify other FOREIGN KEY constraints.
This worked in Sql Server 2000, but not 2005. I just wanted the Sku updated in the all other tables when updated in the main Sku table. I guess that I could use a trigger, but shouldn't need to.

How The Heck Do I Use A GUID As A Foreign Key In MSSQL 2005?

Jun 23, 2007

Okay, this is driving me nuts.  It *should* be simple but it is not.  I've spent the last 4 hours scouring the web for what should be a simple thing to find out.
I have the following tables, but everytime I attempt to create a foreign key constraint for the StudentLocations table I get an 'invalid type' error.  I have a GUID as the PK for the Students and the Locations table.  However, since I cannot create two GUIDs (as far as I can tell) for my StudentLocations table, I have instead defined the StudentLocations.StudentID, and StudentLocations.LocationID as binary(16).  Unfortunately, I can't match this binary(16) to the GUID Identity in a foreign key because I keep getting this stupid error of 'invalid conversion type!'. 
 So, how do I do what I am trying to do using GUIDs as my PK for the Students and Locations tables, and the above defined StudentID, LocationID in a StudentLocations table?
Thanks in advance for answering this question.  I should spend 5 minutes searching and then come here in the future...it's way less frustrating!:
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON

Hi!

Is it possible in SQL 6.5 to create a Foreign Key on a field that
has a datatype of SMALLINT? I have created FK`s with
other datatypes, but it doesn`t seem to work with this particular
datatype. Is there some trick to this?


Thank you for your assistance!

Foreign Key

Jun 5, 2007

I would like to create a foreign key but the Primary table has 2 fields as it Primary Key. Is there a way to create a Foreign Key that links only on one field of the primary key.



Ex: table 1: id int , language char(2), description varchar(100) PK = ID + language

table 2 : id int, idlanguage int PK = id FK (idLanguage refers to id from table 1)



This cause an error because the foreign key does not include all part of the primary key.

Getting Rid Of Foreign Key, How Do I Do That

Apr 13, 2008

Hi everyone,
My main table has a column named "customer" which is a foreign key pointed to my secondary table consisted of a column "customer_id".
I wanted to change my secondary table's customer_id's name into another name whereby deleting it and create a new column instead (i dont know another way of changing names by code) but i'm not allowed to do that due to "customer_is"'s being attached to my main table as FK.
Any suggestion how to do it ?
Thanks a lot.

How Do I Create A Foreign Key

Apr 27, 2007

I have a one to many relationship between two tables. The master table is keyed using an int ID field set to IsIdentity yes and this is the primary key. The field name is ChurchID. Likewise the detail table has such a field as it's primary key and is named ContactID.
 I carry the ChurchID field in the detail table and would like to make it the foreign key. I could not find this explained in the two books I have and the help was anything but that )perhaps it's just me afterall).
 Well, any help in this matter would be greatly appreciated as I find myself at a standstill until this can be resolved.
Thanks in advance.

Help With Foreign Key Relationship

Items TABLEint ItemId PKvarchar ItemName      :

So  basically I have a one-to-many relationship between Items and Categories, in other words each item is associated to one or more categories and this association is done via the X_Items_Categories cross table. On this cross table I set two constraints:


The CatId of each entry in the cross table (X_Items_Categories) must exist in the Category table, and

Foreign Key Tangle

Aug 12, 2005

I'm using stored procedures to update my tables. If I disable the foreign key constraint all works perfectly. Otherwise I get this error:INSERT statement conflicted with TABLE FOREIGN KEY constraint 'FK_wansub_invoice'. The conflict occurred in database 'test1', table 'invoice'. The statement has been terminated. I don't understand why I'm getting the error, because when I disable the constraint even the foreign key fields are updated properly and there is no apparent conflict with the linked table. I've included my c# code and the stored procedure below.FYI the foreign keys in question are InvoiceDate, AccountNum, CarrierId, and Cycle. These are the primary keys in the "invoice" table, and foreign keys in the "wansub" table. It is vital that all records in the wansub table are matched with a record in the invoice table, so I have to have this constraint in place. C# code to create parameters and call the sp:

Conditional Foreign Key - Can It Be Done???

May 17, 2001

Hello Folks,

Well I've hit the wall on this one:

I'm wondering if one can designate a conditional foreign key that relates to one of many different tables depending on the "type" column in the foreign key's. My goal is to come up with some SQL code that will allow for this in a Create table statement. (By the way I'm using MS SQL-7 but I'm wondering if this can be done in general.)

I have two simple cases below that show illustrate what I'm trying to do:
Thanks in advance, -JerryZZ


---------------------------------------------------------
Case 1: The foreign key relation is to a primary key

Table: Invoices
-Fields:
---InvoiceID ..... (primary key)
---BilleeID ...... (fkey to Manfacturers.ManfID IF BilleeType=M)
...................(fkey to Distibutors.DistID IF BilleeType=D)
---BilleeType .....(constraint = M or D)

Table: Manufacturers
-Fields:
---ManfID ........ (primary key)
---CompanyName.. (not null)

Table: Distributors
-Fields:
---DistID ........ (primary key)
---CompanyName .. (not null)



---------------------------------------------------------
Case 2: The foreign key relation is to a unique "not null" non-primary key

Table: InvoicesEmail
-Fields:
---InvoiceID ..... (primary key)
---EmailAddress .. (fkey to Manfacturers.EmailAddress IF BilleeType=M)
...................(fkey to Distibutors.EmailAddress IF BilleeType=D)
---BilleeType .....(constraint = M or D)

Table: Manufacturers
-Fields:
---ManfID ........ (primary key)
---EmailAddress .. (unique, not null)

Table: Distributors
-Fields:
---DistID ........ (primary key)
---EmailAddress .. (unique, not null)
