Hi Experts
we have a merge replication in place between 2 databases.
User A has created a constraint between a replicated table "R" and the non replicated "NR"
And the replication started failing
The error comes up like 'the Schema Script could not be propagated to the Subscriber'
i tried deleting the constraint but the replication still fails
Should i remove the schema script

I have tables that are replicated using transactional and merge replication. As a result I am unable to use automatic identity management as transactional replication doesn€™t seem to understand it.
Therefore I have implemented a version of the automatic mechanisms that seems to work in a hybrid environment. It is based on a central table that holds the maximum identity for each table that has been issued to date. Valid identity ranges are issued to each publisher and subscriber as needed in a similar way to the automatic mechanisms and tables are reseeded as needed.
I want to enforce the ranges in a similar way to the automatic mechanism using a check constraint similar to this:
alter table [dbo].[test1] with NOCHECK add CONSTRAINT repl_identity_range_48DF13ED_D503_4F5C_AED9_4E504D03E752 check NOT FOR REPLICATION (([id] > 10001 and [id] <= 20001) or ([id] > 50001 and [id] <= 70001))
This works OK on a client subscriber, but if the change is made on the publisher, then the alter statement itself is replicated out to all clients €“ which is not what is wanted. I have traced the automatic mechanisms using profiler and they issue an alter statement as above €“ following dropping of the constraint €“ but the check constraint isn€™t replicated. I can't see how this is achieved.
How do I stop the check constraint being replicated?
The article property schema option can be set to stop replicating check constraints, but this seems to have no effect. If the publication property replicate_ddl is set to 0 then I do see the behaviour that I want. However, I do need to be able to replicate most schema changes due to upgrades etc €“ so this doesn€™t look like a viable option €“ except possibly for the transactional publication.
Any help would be much appreciated
Thanks

We have a two SQL Server 2005 databases set up using Transactional Replication. My manager has asked me to set it up to replicate constraints (default, fk, et) on the tables in the main publication. I said sure, I can do it, but I will have to re-initialize the subscription. He said there was a way to do it without re-initializing the subscription. I cannot find anything in my research to indicate that there is a method to do so (via call sp_ functions, etc). Is it indeed possible to replicate constraints on replicated tables without re-initializing the who subscription? The reason he does not want me to perform a re-initialization is that we are a few weeks before moving into production, and a full re-initialization takes 1.5 days, which would impact system availability.
Thanks in advance for any advice.
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 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?
Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints.
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'm using MS SQL 2000 with enterprise manager I have a customers table called high_customer, it has a primary key called IDI have an invoices table called high_invoices, it has no primary keys but it does have a column for customer ID.I want to set it so if a customer is deleted from the customers table, any invoices with that customerID are deleted from the invoices table.Do I need to specify a constraint? If so how do I do it in enterprise manager.Thanks

I have the following problem:
I have a table called Jobs with the fields:
JobNumber, Name, Customer, ...
And a table called Customers with the fields:
ID, Name, Address, ...
Obviously Jobs is linked to Customers with the Customer<->ID fields. I want to set it up so that if a Customer is deleted, then any Jobs that had that customer listed now have the Customer field set to NULL. Can I do this with a constraint, or will I need to use a trigger?
Cheers,Little'un

My table structure is something like this :
ORDER_ITEM (OrderSK, ItemNumber, Qty, ServiceSK, UnitPrice)
SERVICE (ServiceSK, Description, UnitPrice)
How could I modify the database structure to enforce the data constraint that ORDER_ITEM.UnitPrice must be equal to SERVICE.UnitPrice for the corresponding service.

Hi,
Just getting into scripting sql. I have a little script that adds and drops a default value for a column. But I cannot get it to run when the column already has a default value specified. If I didn't script the contraint and specify a name I have no name to specify when trying to drop it.
ALTER TABLE users ADD CONSTRAINT dev1 DEFAULT 1 FOR ns_email_flag
ALTER TABLE users DROP CONSTRAINT dev1
How do I remove any existing default values using script?
TIA,
Seoras.
How does one know what a particular trigger or constraint is supposed to be doing on a table. I am just two days old on this position, and no form of documentation, at the same time I am expected to trouble-shoot some error messages. Thanks for your help.
View 3 Replies View RelatedWhen I first set up my database, I set it up with many unique constraints, but not much in the way if indexes. After reading more about the benefits of indexes, I'm thinking of deleting many of the unique constraints, and replacing them with unique indexes where appropriate.
It seems that indexes would be better than unique constraints in many cases, because you have the double benefit of enforcing uniqueness, as well as improving sorting capability. Does this make sense?
Hi folks,
Wonder if I'm onto something....everything I've read says that to drop foreign key constraints, you have to drop/recreate the table.
I've been able to dynamically create the ALTER TABLE statements for all FK constraints in a database. The way I did was a little convoluted (Access 97 linked tables and pass-through queries, cut/paste from the debug window to SQL7 QA), but it does work. More importantly, it saves the hassle of dropping/recreating tables....Someone with more expertise than I in using nested cursors could probably convert it to pure T-SQL pretty easily.
Just curious...opinions? Be glad to post the code here if that's appropriate.

Can anyone recommend a good article/book on the subject? I am trying to find out more about compound primary keys. How many is “too many”? Does the number of primary key columns affect your performance? If so, how does it affect it? Should some of the constraints be handled from stored procedures?
Any response is greatly appreciated.

View 1 Replies View RelatedHi,
I am developing a database for my company in SQL server 2000 and I have some
few problems.
Firstly.
I have a customers table and orders table in my DB:
Customers Orders
--------- ------
CustID (primary key) ----------------< CustID
. ^ ProductID
. | Quantity
. | .
. | .
etc. | etc.
|
relationship
(one to many)
What I want to do is:
1) to be able to delete a Customer and automaticaly SQL server delete all the
orders that this customer done from the Orders table.
2) If for some reason the CustomerID changes, SQL should be able to
automaticaly update the necessary fields with the new values in the Orders
table.
Finally, 3) I want to be able to insert a new customer that has an order
and update both the Customers table and Orders table automaticaly. e.g
CustID Name Address ProductID Quantity etc.
------ ---- ------- --------- -------- ----
10-003 John London 33-25 2 ...
Such a kind of insert should add automaticaly the following entries in the
two tables:
Customers Orders
--------- ------
CustID (10-003) CustID (10-003)
Name (John) ProductID (33-25)
Address(London) Quantity (2)
. .
. .
etc. etc.
A friend of mine told me that this can be done using Foreign Check constraints
in SQL server. But I do not know what to do.
Can anybody help me please?
Thank you very much.

I have a question regarding the use of check constraints. I see how to set it up to make sure a value entered is one of a list using this syntax:
([eft_vc] = 'No' or [eft_vc] = 'Yes')
However, rather than have to hard code the allowable values, I'd like to have them read off another table. The logic would be as follows:
([eft_vc] in (select * from eft_t))
When I try to put this in, I get a message saying that constraints do not support subqueries. Does anyone know of a way around this?
thank you,

What is the difference between creating a Unique Constraint and Unique Index? How does creating Index/Constraint affect my performance and db size?
Thank you.
Can someone help me with this check constraint. I'm trying to get it runned on MS SQL Server but it seems the syntax isn't correct
check((Derived_Val=0) or ((select count(*) from Stage_One where Task=U_Id and Quantity is null)=0))
Thanx

I am Trying to add a check constraint that if the paymenttotal is 0 the column is allowed to have null and if its greater then 0 it is not allow to have null. Here is what I have so far but i get some syntax errors, See if you can see what im doing wrong and how to get this to be valid. Thanks
heres what I got so far
Code:
ALTER TABLE Invoices WITH CHECK
PaymentDate SMALLDATETIME NULL,
CHECK (PaymentTotal = 0)
PaymentDate SMALLDATETIME NOT NULL,
CHECK (PaymentTotal > 0)
I also had this before i changed it to that and I got syntax erros as well but i dunno which is closer.
Code:
ALTER TABLE Invoices [WITH CHECK]
ADD CHECK (PaymentTotal = 0), PaymentDate SMALLDATETIME NULL,
ADD CHECK (PaymentTotal > 0), PaymentDate SMALLDATETIME NOT NULL
Can someone give me some good examples of check constraints that I can apply to my fields.
For example can I apply a constraint on a name field, at the moment I use one for the date but would like to know many more.
So if anyone has any useful check constraints handy then please tell.
Thanks

Hi,
I have relationships built for several tables and I want to bypass the FK restraints when deleting/truncating a table. The FK works fine when some one is trying to delete soemthing within the application, but on an administrative level, it is becoming VERY BOTHERSOME! Any help will be greatly welcomed!

I tried a little experiment. I took the constraint off of my two main tables, "manufacturers" and "products". I tried to TRUNCATE the tables again and I got the same error message. My products seems to have other contraints with two other tables. I checked out the two tables and both of them are empty. What's the deal!?! Again, any help is welcomed!

Updated 8/24 @ 17:02
Ok so I tried to disable the constraints: ALTER products NOCHECK CONSTRAINT ALL, but it didn't work with truncating.
Hi,
I am new to MsSql. I want to know is there any command through which we can get all the consraints on a table or in a databases. In the same way how to get the all table names in a database from the coomand prompt or thorugh query analyzer.
