Failed To Enable Constraints. One Or More Rows Contain Values Violating Non-null, Unique, Or Foreign-key Constraints.
Jan 17, 2008
Hi,
I am getting the above error when trying to load a report into my Web Application, I have tracked the error down to one specific field in my database. Even though this field is a NVarChar field and is of size 30 it would seem that there is an issue returning the value from the field. I can write it into the database no problems but when I try to get it out of the database it returns the above error.
e.g
MOB 401.908.804 - Fails
0401.907.324 - okay
8239 9082 (pager) - fails
Anyone got an idea on how to fix this????
Regards..
Peter.

I know this is probably a flick of a switch but I cannot figure out which switch. Setup is SQL Server / Stored Procedures / DAL / BLL(skipped for testing) / PL. The stored procedure queries from only one table and two columns are ignored because they are being phased out. I can run the stored procedure and preview the data in the DAL but when I create a page with an ODS linked to the DAL and a GridView I get this error. I checked every column that does not allow nulls and they all have values. I checked unique columns (ID is the only unique and is Identity=Yes in the table definition). I checked foreign-key columns for values that are not in the foreign table and there are none. Any ideas why do I get this?

I have to admit I'm pretty new to ASP.net.
I'm trying to insert a row of data into my SQLExpress database table "Prets"
I'm getting the user_ID from the table "Membres"
Here's the code I have:
Imports System.Web.UI.PageImports System.Security.PrincipalImports WiseNetTableAdaptersPartial Class membre_sec_Pret_demande_pret Inherits System.Web.UI.Page Protected Sub submit_btn_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles submit_btn.Click Dim User As String = My.User.Name Dim pretAdapter As New PretsTableAdapter Dim membreAdapter As New MembresTableAdapter pretAdapter.AjouterPret(Convert.ToInt32(membreAdapter.GetUserIDbyName(User)), Convert.ToDecimal(montant_txt.Text), Convert.ToString(raison_txt.Text)) End SubEnd Class
And here's the error I get at runtime:

Hello there, I have a table under SQL2005 express with 8 fields with a primaryKey defined.In my BLL in the table adapter there is one "SELECT DISTINCT prodCAT from prods" The prodCAT is a nvarchar(50) and it is not part of an index or primaryKey.When I preview the data from my BLL I get the correct data.I defined a new web form (aspx) and put a ddl (dropDownList) with an objectdataSource that relates to the above sql function/command and I get a"Failed to enable constraints. One or more rows contain values violating
non-null, unique, or foreign-key constraints." BTW when I defined the above SQL in the BLL I got a "The new command text makes the function return data with schema different from the schema of the main query" Any suggestions???

Hi,
I have two tables (Accounts and Contacts) that have a many-to-many relationship, maintained by the AccountContactLinks table.
I would like to populate a Contacts DropDownList with all of the Contacts associated with the Account Selected in Accounts DropDownList.
Here is the (SP) SQL Query I'm trying to make work:
SELECT Contact.ContactID, Contact.ContactLastName, Contact.ContactFirstName, Contact.ContactLastName + ', ' + Contact.ContactFirstName AS ContactName FROM Contact INNER JOIN AccountContactLinks ON Contact.ContactID = AccountContactLinks.ContactID WHERE (AccountContactLinks.AccountID = @AccountID) ORDER BY Contact.ContactLastNameEND
I keep getting the following error:
Failed to enable constraints. One or more rows contains values violating non-null, unique or foreign key constraints.
I haven't implemented any non-null, unique or foreign key constraints between any of these tables, so suspect that I've got the SQL Query wrong.
Thanks very much.
Regards
Gary

Hi, I am trying to use a typed dataset created using the Query builder which returns the data correctly when I use 'Execute Query' in query builder but as soon as I attempt to return a dataset using the GetData method created I get the following error: Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints. Which is not very helpful, any ideas where the problem may be? I have tried switching off enforce constraints and setting the NullValue property of all strings to 'Emtpy' bu that has no effect. Thanks in advance

I have two tables, T1 and T2.T1 has a foreign Key that refers to a key in T2.The way that I see it, its only possible to insert something into T1 ifthere already exists a tuple in T2 with the same value in key.That means that I always have to insert something into T2 before insertinginto T1Is that correct?

When following a script to create some tables and constraints, it is recommended that you name the FK constraint? Otherwise it appears with numbers after it. Is this the way 2005 creates them or has this always been the naming convention?

I want to disable foreign key constraints en mass. Is there a way to do this?
I know that I can go into each table and navigate to the Relationship tab of Properties and uncheck the "Enforce relationship for INSERTs and UPDATEs" box, but I'd much prefer to automate this process with a query since there are 160+ tables and probably 200+ relationships to disable.
I figure that sysconstraints my be the ticket, but I will keep experimenting until I get the right solution. In the meantime, any insight to steer me in the right direction is appreciated.

Hi All,
I know that when you specify a PRIMARY KEY or UNIQUE constraint for a table, SQL Server creates a unique index for the primary key columns.
What about foreign keys? Does SQL Server creates an index when you create a foreign key?
I have looked in Books Online and on the Internet, but couldn't find any information.
Thanks in advance.

I've recently implemented a whole bunch of foreign key constraints in a database. As a result I have issues every time I want to truncate a table to perform data loads.
Is there an easy way to tell the system to ignore these constraints for the term of a data load or truncation of data?
thank you

I have recently restored an SQL Server 2000 database on SQL Server 2005
A number of constraints on the database had previously been disabled
A monthly process that is carried out, imports data into 'Table A'.
This process now crashed, being unable to truncate table as it referenced by 'Table B'
Although when i check the properties of the constraint the 'enforce foreign key constraints' is set to no.
Is there a known issue with restoring databases on 2005,
Any help greatly appreciated.

I need to ensure that each record in a table is unique in terms of two fields. E.g. Job No. 1 and Phase 1 cannot exist twice. I've tried to achieve this using a compound primary key but am having no joy. Im sure its a simple issue, any suggestions?
Thanks

I have a table that I want to run an UPDATE statement to change some data in the table, but I get this error:
Server: Msg 547, Level 16, State 1, Line 1
UPDATE statement conflicted with COLUMN FOREIGN KEY constraint 'FK__Yield__Financial_Product__ProductCode'. The conflict occurred in database 'lsmdb', table 'Financial_Product', column 'ProductCode'.
The statement has been terminated.
How do I update the ProductCode column in both tables to reflect my updated data?
Thanks in advance.

How can I get and or set the order in which the cascading deletes of a table are executed??
I have table A with cascading deletes to Table B and Table C. Records in table B can not be deleted if they are referenced from table C. So if I delete C, then B and then A; that would work. But B then C and then A might be prohibited due to the constraint between B and C. Therefor the order of execution of the cascading delete is important.

Hello, I want to write a unique constraint that applies to more than one column. What I mean is that the uniqueness should be that if column A is 5 and column B is 3 no other row where A and B has those values can exist.
Do I write this as a check constraint ? Or how do I do it ?
Also, is there anyone who knows some good reading on how to use Link Tables (many to many relations) in MS SQL Server ?

I want to replicate the foreign keys to secondary.I changed the value Copy foreign key constraints value is to True.
I changed this value at pub properties - Articles -
And then it is asking for MARK for reinitialization with the new snapshot.I clicked ok.
When I checked sync status it has given the message like initial snapshot is not yet available.I started the snapshot and the subscription started replication records.When check at pup properties the value Copy foreign key constraints again false.
After changing the value to true it is showing as False.

I have one table like below Test table. My requirement is to create constraints to confirm <g class="gr_ gr_331 gr-alert gr_gramm Grammar only-ins replaceWithoutSep" data-gr-id="331" id="331">uniqueness</g> of STID value 101 with LN.
like
ID - LN - STID
1 - 'ABC' - 101 ---- Valid Row
2 - 'ABC' - 202 --- Valid Row
3 - 'ABC' - 202 --Valid Row (as I want only unique when LN = 'ABC' with STID = 101)
4 - 'ABC' - 101 -- Invalid Row (As I want uniqueness base on LN and STID = 1011)
create table dbo.Test
(
ID int identity,
LN varchar(50),
STID bigint
)
Is this possible with constraints as I don't want to use <g class="gr_ gr_1041 gr-alert gr_gramm Grammar only-ins doubleReplace replaceWithoutSep" data-gr-id="1041" id="1041">trigger</g>.

Ok, so I've broken down and decided to write myself an invoicing
program. I'd like to use GUID fields as the Primary Keys in my
table. Now, I basicly bill for two seperate items:
Deliverables and Services.
So, my Layout's gonna look something like
Create Table Invoice(
ID UniqueIdentifier Primary Key,
-- Other Data
);
Create Deliverable(
ID uniqueidentifier Primary Key,
ParentInvoice uniqueidentifier,
-- Other data);
--...
Im sure there are probems with that as it's written feel free to edify me as to what they are.
my questions are such:
1) Does a uniqueidentifier field automagically get a value?
2) If not how do I generate one in TSQL?
3) If so, what do I use to store my Foreign Keys.
4) How do I declare my Foreign key constraints?

Guys,
I have 600 tables in my database, out of which 40 tables are look up value tables. I want generate truncate scripts which truncates all the tables in order of Parent child relationship excluding lookup tables. Is there any way to do this apart from figuring out Parent Child relationship and then writing the truncate statements for each of the table.
For example
EmployeeDetail table references Employee table
DepartmentDetail table references Department table
Department table references Employee table
My truncate script should be
TRUNCATE TABLE DEPARTMENTDETAIL
TRUNCATE TABLE EMPLOYEEDETAIL
TRUNCATE TABLE DEPARTMENT
TRUNCATE TABLE EMPLOYEE
Is there any automated way to figure out parent and child tables and generate truncate script for the same.
Thanks

hello .
i have a grid for a table that gets updated with recordset.updatebatch
for a multi-user application.
the problem is that some of the table fields have to be unique
now imagine the next situation.
user A opens the form
user B opens the form
user A writes '1000' in the unique field
user A saves the recordset with updatebatch
user B writes '1000' in the unique field
user B saves the recordset with updatebatch
now there will be two records with the field '1000' !
how can i avoid this ?
i cannot check for unique during the update event of the grid
because it should check during the time it is saving and not
when it is just entering data without having updated the recordset
thanks !

I'm working on creating a new version of an existing table. I want to keep the old table around, only with a different name. In looking this up I found there's a system routine named sp_rename, which looks like it will work fine.However in thinking about this I realized that the foreign key constraints defined on the table (there's 3 of them) are likely to not be renamed, correct?
If I'm correct, then I suppose I could rename the table, then drop the 3 foreign key constraints, and create them new using different names for those foreign key constraints.
