Redefining An Auto-generated Primary Key Constraint Name
Jan 9, 2007
Hey there :)
I'm using Ruby on Rails to create a migration of a legacy database on
an MS SQL Server. I'd like to name my constraints myself, such as
'pk_authors', but in the cases where a table has an auto incremented
IDENTITY(1,1) id field, Rails takes over and adds the primary key
itself when creating the table.
This is fine, except then the constraint gets a name like
'PK__authors_384934' which is not very intuitive or easily remembered
;)
I'd like to just throw in an 'ALTER TABLE authors...' statement just
after that table has been created, but I'm not sure how to go about
renaming the auto generated constraint since the name it gets is
partially random. Is there any way to indirectly refer to the
constraint like 'RENAME PRIMARY KEY CONSTRAINT ON authors TO
pk_authors' or something like that, so that I can rename the
constraint?
Thanks in advance,
Daniel Buus :)

hi guys,
just a question regarding database design
i have a table with an auto-generated primary key but the problem is this:
say i have 4 records,so logically they'll be numbered 1 to 4.so the problem is whenever i delete all records and add new ones,the numbering will start from 5 and not 1 again.
how do i remedy this?
thanx

Hello,
I've a problem with auto-generated key. In my parent table, some lines have been deleted. I would like to add new lines with the same content in order to restore my database, but I cannot decide on the id value which is an auto-generated key. Is there a solution to set an auto-generated key with a specific value ?
Thank you in advance,
regards,
mathmax

I downloaded the AdventureWorks OLTP Schema and am trying to use some of the design concepts that are used in this example but I don€™t quite understand some things.
First there is a column named rowguid, at the moment I assume that this is a GUID. If this is wrong most likely my next question will make no sense.
Second if that is indeed a guid all the tables have another id; example would be Employee table would have employeeid and rowguid, why do this? My best guess is that you would use the guid to easily insert (linked/sync) data into multiple tables without needing to retrieve the id from the table that was first input into. My scenario would be inserting an employee; to insert an employee you need to create a row in the employee, contact and address tables and for ease you would use the guid to link these rows. But if this is the case wouldn€™t there be sync issues that would arise?
If my guess is totally off please correct me also if anyone can direct me to some good resources that cover database design.
The schema can be downloaded at http://www.microsoft.com/downloads/details.aspx?familyid=0F6E0BCF-A1B5-4760-8D79-67970F93D5FF&displaylang=en#filelist
Thanks for any help.

My question: Is it okay to drop all the auto generated column statistics? (for the following scenario)
- I am cleaning up unnecessary objects (tables, unused indexes, overlapping statistics etc) from databases and found out there are more than 1400 auto generated column statistics on one database (lets call it A).
- Database A was used to be our reporting database but from last several years we are using database B for reporting. DB A has all the historical data while DB B only has valid records.
- We are updating all the column statistics with full scan nightly on database A and it is talking almost 2.5 hours to do that. Now I want to drop all the "unnecessary" statistics those were created when DB A was reporting database and they are no longer in use. There is no way to know the creation date of the column statistics that I know of. Statistics "last update date" is of no use because of our nightly job. So I was thinking of dropping all the auto generated column statistics and let the sql server create as it needs from now.

Ok, let's say that I do a following inline INSERT statement.....
INSERT INTO Car ( carMake, carModel ) VALUES ( 'Honda', 'S2000' )
When I do this, a carId int value will automatically be generated because it is the Car table's PK and is an int identity. How do I obtain this value so I can immediately use it in let's say, the following example.
INSERT INTO Person ( carId ) VALUES ( @carId ) ..... where @carId is the value I need
Maybe you would say I should do something like.....
SELECT carId FROM Car WHERE carMake = 'Honda' AND carModel = 'S2000'
However, let's assume that the carMake and the carModel fields are NOT unique. I'm sure there's an easy way to extract the new identity value (maybe even in the same query) as the INSERT, but I just don't know how.
Thanks.

We have implemented a very small reporting database which has a main table that started off small and has now grown to around half a million rows. Initially, there were no indexes on the table apart from a clustered index, but as the data has grown, performance has dropped and so we have added a number of indexes. This has resolved the performance issues.
Before creating the indexes SQL Server had auto created a number of statistic objects (_WA_Sys_000... etc). After creating the indexes, new statistic objects where created for the new indexes. In some cases, there are duplicate statistics (auto and index) for the same columns.Should I go through and drop the duplicate auto statistics? Will having duplicates cause issues at all?

Dear all,
I would like to use SSIS to populate product information from a remote database to a local one.
There are Product table (which contains the basic information) and ProductImage table(which contains the product images in binary).
I would like to use a join query
SELECT A.name, A.price, B.image from Product A INNER JOIN ProductImage B WHERE A.ProductImageID = B.ProductImageID
to return all the product information from the remote database.
When populating the local database, the local ProductImage table will be populated first and then the local Product table will be populated with the ProductName, ProductPrice return from the query together with the newly genetated ProductImageID afer insert a record into the local productimage table.
The ProductImageID column is set as the identity column in the ProductImage table.
I am very new to SSIS. Is there a way to handle this scenario? What components do I need to use?
Thanks

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

Hello,
I am getting the following message when I am trying to insert into my table. Request is the primary keys and the Bus_Req_Id and Test_Case_Id are both foreign keys. The data that is being inserted into these fields are not unique.
This is the exact error message:
Violation of PRIMARY KEY constraint 'PK_REQUEST_BUS_REQ_TST'. Cannot insert duplicate key in object 'REQUEST_BUS_REQ_TST'.
The statement has been terminated.
I am trying to insert 700 - 900 rows based on certain criteria. If I delete the keys the inserts will work.
Any help would be most greatful.
Thank you in advance

I know what this error means is that you can not insert duplicate primary keys in the table but the thing is I am checking the rows if they do not exist then insert otherwise don't do any thing these are the lines I am writing in my strored procedure can someone please let me know what I am doing wrong here.
If not exists
(Select * From GGP WHERE
FFECTIVE_DATE =@v_EFFECTIVE_DATE AND
ASSET_ID= @v_ASSET_ID AND
ASSET_TYPE = @v_ASSET_TYPE AND
Value = @v_Value AND
hour = @v_Hour)
INSERT INTO GGP
(ASSET_ID,ASSET_TYPE,Hour,Value,EFFECTIVE_DATE) values(@v_ASSET_ID,@v_ASSET_TYPE,@v_Hour,@v_Value, @v_EFFECTIVE_DATE)
The exact error is

When I try to insert data into a table (let's just call it MyTable for this post), I suddenly get the following error.
Violation of PRIMARY KEY constraint 'PK_MyTable'. Cannot insert duplicate key in object 'MyTable'.
My table does have a primary key field named 'id', which is an auto-incrementing BIGINT. The last record I successfully inserted received 14 in the id field, so I'm assuming the database is trying to assign 15 to the next. Unfortunately, there is already a record with an id of 15; the next available id is 21.
Is there a way to avoid these primary key collisions?

Hi All,
I have a table that has 3 columns, two of them make a composite primary key. The table is populated with data. What I need to do is to add a third column to a composite primary key. I have tried to do that with the following command:
alter table databasesize
add constraint pk_dbsize primary key (dbid)
But I get the error message:
Table 'databasesize' already has a primary key defined on it.
How can I do this?

I have an odd problem on something that used to work fine.
I have an SP that inserts a record into a table (Contract) with two keyed fields.
The keys are as follows:
ContractID and SeqID (Sequence)
These two keys make the records unique.
Ex:
ContractID SeqID
12345 1
12345 2
12345 3
etc....
Several weeks of using this procedure have been fine. Suddenly I started getting this error:
Violation of PRIMARY KEY constraint 'PK_contract'. Cannot insert duplicate key in object 'Contract'.
The statement has been terminated.
I verified that the values do not violate the constraints. In fact, I can type the exact information into the table directly without a problem.
Has anybody experienced this before?
Any help would be apprciated!
Here is the code in the SP;
CREATE PROCEDURE bcipNewContractSeq @ContractID Char(10 )AS
DECLARE @MaxSeqID int
DECLARE @NewSeqID int
SELECT @MaxSeqID = Max(SeqID) from Contract_Live..Contract WHERE ContractID = @ContractID
SET @NewSeqID = @MaxSeqID + 1
--Copy Contract info for new seq with new seqid- record has default start and end dates
INSERT INTO [Contract_Live].[dbo].[Contract] ([ContractID], [seqID], [Status], [ContractName])
SELECT @ContractID, @NewSeqID, 'In Process', ContractName
FROM [Contract_Live].[dbo].[Contract]
WHERE [Contract_Live].[dbo].[Contract] .ContractID = @ContractID
GO

Hi,
I've a set of source tables on one server and a set of destination tables on another.
When I move data from one server to next, I get an error saying "Violation of Primary Key Constraint". This happens for only one table among the 6 tables that I have. I dont understand why it throws me this error. Though theres an error for this table, the data from source table moves into this destination table.
Am I missing something?
Thanks,

Hi all,I have a table where I have my ProdPK set up as Primary key, turned on "Is Identity" and set the Identity increment to 1. But each time I add a new item, the number incremented by 2... I have couple of other tables and they are all fine, just this particular table increased twice as it should. I check the setting against other tables and everything seems to be the same. By the way, this is adding the data to the table inside MS SQL Server Management Studio manually. I haven't done anything in the ASP.NET page yet. Thank you very much,Kenny.

Dear all,
I am using SQL express 2005 in visual studio 2008. I would like to use Form View to insert new record in the table. There is a column call "id". I think it is too stupid to let user enter a unique identifier instead of generating by the system.
I know how to generate a random integer number in a normal TextBox. However, when I edit the InsertItemTemplate, I cannot modified the value of that textbox. For example, i couldn't use "TextBox1.Text = temp;" here. How can I achieve to change this TextBox's value by the system that I would like to generate a random interger. Thanks a lot.

I want a table to have an int auto primary key, that will fill in deleted rows.
EG
1
2
4
5
8
The next primary key should be 3 (NOT 9)
This table changes often, so just adding 1 to the last number used, will fast run out of numbers.
The table is accessed by many users, so it can not be manually generated.
