Dec 13, 2007Here is my sqlce:
Code Block
alter table tblV
add constraint
foreign key (T_ID)
references tblT(T_ID)
on delete set null on update cascade
Error is:
Major Error 0x80040E14, Minor Error 25501
There was an error parsing the query. [ Token line number = 3,Token line offset = 1,Token in error = foreign ]

Error Whilst Adding Foreign Key
Jan 4, 2008I've been getting what I think is a bizarre error message whilst trying to create a foreign key between two tables.
tblDailyComments has a primary key of DiaryID
tblDailyOperatingData has a column DiaryID.
Both are Int (4).
Yet when I run the following:
ALTER TABLE tblDailycomments
ADD CONSTRAINT FK_tbldailycomments_tblDailyOpData
FOREIGN KEY REFERENCES
tblDailyOperatingData(DiaryID)
I'm getting the error message:
Server: Msg 8139, Level 16, State 1, Line 1
Number of referencing columns in foreign key differs from number of referenced columns, table 'tblDailycomments'.
I also tried to create the relationship in a database diagram and this brought back errors as well.
Any help would be much appreciated.

Adding A Column With Foreign Key Constraint
Oct 1, 2007
Hello!
I am trying to alter a table adding a column with foreignkey constraint. The table that holds the primary key in that relation has data, so i am not being able to execute the alter statement.
This is the error:
Server: Msg 547, Level 16, State 1, Line 1
ALTER TABLE statement conflicted with COLUMN FOREIGN KEY constraint 'FK_MOPAeroportoICAO_IDMOPAlimentacaoFerroviaTipo'. The conflict occurred in database 'MOP', table 'MOPAlimentacaoFerroviaTipo', column 'IDMOPAlimentacaoFerroviaTipo'.
This is the script:
ALTER TABLE MOPAeroportoICAO
ADD IDMOPAlimentacaoFerroviaTipo [int] DEFAULT 0 NOT NULL
CONSTRAINT [FK_MOPAeroportoICAO_IDMOPAlimentacaoFerroviaTipo] FOREIGN KEY
REFERENCES MOPAlimentacaoFerroviaTipo (IDMOPAlimentacaoFerroviaTipo)
How can i turn of check when i add the foreign key ?
Thanks in advance

Sep 14, 1998Hi!
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!

Jun 5, 2007I 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, 2008Hi 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, 2007I 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.

Help With Foreign Key Relationship
Jul 3, 2007When I try to insert a record on my DB (SQL 2005 Express) I get a constraint error. This is my table setup which has been simplified to expose the problem I have:
Categories TABLEint CatId PKvarchar CatName :
Items TABLEint ItemId PKvarchar ItemName :
X_Items_Categoriesint CatIdint ItemId
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

I'm encountering the following error when I try to enter data into a particular table:The INSERT statement conflicted with the FOREIGN KEY constraint "FK_CMRC_ProductImages_CMRC_Products". The conflict occurred in database "hscom", table "dbo.CSK_Store_Product", column 'productID'. The statement has been terminated. I understand what's happening theoretically, but I don't know where to look for where the constraint is defined, or how to fix it. I don't see FK_CMRC_ProductImages_CMRC_Products as a file name or a stored procedure. Diane

Foreign Key Tangle
Aug 12, 2005I'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, 2001Hello 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)
