View 1 RepliesHi Folks,
I would like to create a table with primary key pair:
Key1 : nchar(10)
Key2: nchar(10)
Value: money
That is, Key1 and Key2 are the primary key columns for the table. I would like to think of (Key1='Foo', Key2='Bar') to be the "same" as (Key1='Bar', Key2='Foo'). Is there a way to enforce this as a table constraint, or do I have to enforce this manually in all procedures that modify and read the table?
Thanks!

Hi,
We will be using SQL Compact Edition in our application. We are doing some tests to make sure that SQL Compact is suitable for our requirments.
Our problem is with Primary keys and how to maintain data integrity since we will have 100+ clients inserting, updating, and synchronizing with SQL Server.
Can we control Identity range?
Shall we use UniqueIdentifires insted of int?
How can we detect errors at the client side? (For example, if two clients are trying to synchronize 2 columns with the same primary key value)
We will use Merge replication.
Thank you
I have a problem that has been frustrating me for a long time, simply because I know this has to be somewhere but I cant seem to find where to toggle this setting.
I have a large number of tables that I regularly send to a remote server using the DTS Export Wizard in SQL Server Management Studio 2005.
Although I have toggled "Enable Identity Insert", as well as "Drop and Recreate Destination Tables", my tables upon completion are missing their primary key constraints, as well as its Identity attribute.
I have to go in manually to each table and set the column that is the PK, and the Identity attributes - all my stored procs break as a result of the missing constraint.
What setting do I need to flag during the DTS Export that will preserve the key values for me on completion?
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?
I have table variable in which I am inserting data from sql server database. I have made one of the columns called repaidID a primary key so that a clustered index will be created on the table variable. When I run the stored procedure used to insert the data. I have this error message; Violation of Primary key Constraint. Cannot insert duplicate primary key in object. The value that is causing this error is (128503).
I have queried the repaidid 128503 in the database to see if it is a duplicate but could not find any duplicate. The repaidID is a unique id normally use by my company and does not have duplicates.
How to copy a table from one server to another server with primary and foreign key constraints.
View 5 Replies View RelatedI 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?

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????

Hi,
I have recently been looking at a database and wondered if anyone can tell me what the advantages are supporting a unique collumn, which can essentially be seen as the primary key, with an identity seed integer primary key.
For example:
id [unique integer auto incremented primary key - not null],
ClientCode [unique index varchar - not null],
name [varchar null],
surname [varchar null]
isn't it just better to use ClientCode as the primary key straight of because when one references the above table, it can be done easier with the ClientCode since you dont have to do a lookup on the ClientCode everytime.
Regards
Mike
We have a table, which has one clustered index and one non clustered index(primary key). I want to drop the existing clustered index and make the primary key as clustered. Is there any easy way to do that. Will Drop_Existing support on this matter?

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?

My table structure is something like this :

Hi all
I have the following table
CREATE TABLE [dbo].[property_instance] (
[property_instance_id] [int] IDENTITY (1, 1) NOT NULL ,
[application_id] [int] NOT NULL ,
[owner_id] [nvarchar] (100) NOT NULL ,
[property_id] [int] NOT NULL ,
[owner_type_id] [int] NOT NULL ,
[property_value] [ntext] NOT NULL ,
[date_created] [datetime] NOT NULL ,
[date_modified] [datetime] NULL
)
I have created an 'artificial' primary key, property_instance_id. The 'true' primary key is application_id, owner_id, property_id and owner_type_id
In this specific instance
- property_instance_id will never be a foreign key into another table
- queries will generally use application_id, owner_id, property_id and owner_type_id in the WHERE clause when searching for a particular row
- Once inserted, none of the application_id, owner_id, property_id or owner_type_id columns will ever be modified
I generally like to create artificial primary keys whenever the primary key would otherwise consist of more than 2 columns.
What do people think the advantages and disadvantages of each technique are? Do you recommend I go with the existing model, or should I remove the artificial primary key column and just go with a 4 column primary key for this table?
Thanks Matt
i have a question about constraints in SQL server.
i have three tables:
Client
---------
clientID
name
etc...
Bank
-------
BankID (a virtual number, identity)
ClientID (FK: Client)
BankAccountNumber
BankName
Order
--------
OrderID
ClientID
BankID
a Client an have one or more bankAccounts.. if he place an order, he can select wich bankaccount will be used to pay.
how do i have to set the constraints so that the bankAccount in Order, is allways of THAT client in order.???
Thanx...

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.

Hi,
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,
