UniqueIdentifier Pros And Cons ??
Jul 20, 2005
Hi all
i am building a SQL 2000 database that it is proving a little
challenging, i have companies with multiple addresses, phone numbers,
owning mine sites etc and also joint ventures so maybe you get the
picture with a few design issues that i ma encountering
My queriy is about a primary key identity, and which one to use with
respect to either the identity data type or the unique identifier ,
I am aessentiall building an address table to hold all multiple
addresses as well as phone numbers etc, so my desire to have a unique
identity for each record is very important.
My view is i will run in to violation errors by just using the table
identity data type, i could i suppose use composit primary keys but
that may have a performance impact, although thiis will not be a high
transaction database.
Does anyone know about performance issues regarding each identity
solution, by using a generated 16 bit identifier there are going to be
huge numbers for the DB to verify. or am i worried about nothing?
any views greatly appreciated
regards
Greg

My company is thinking about moving to a product that uses Microsoft SQL Server and I have been asked to find out what are the Pros and Cons of the product, if any.
Any feedback is appreciated.
Thank You

Anyone know where I could find some good articles about pros and cons of upgrading SQL 7 to SQL 2K?
Our boss suddenly got this bug up his rear that we need to upgrade. :(
Probably because we are to a point where everything is running smoothly, and he needs to throw a monkey wrench in it.
We are a very small shop, and are not stressing SQL 7 in the least. I am interested to read some articles about SQL 2K, because right now, I can't see any possible reason an upgrade would be worth doing.
Thanks.

I have a requirement where I need to perform a query for positioninformation. But for some types of entries, I need to "expand" the rowto include additional position rows. Let me explain with an example:An index is a security that is made up of components where eachcomponent has a "weight" or a number of shares. So if I have 1 share ofthe index, I have X shares of each component.AAPL is an Equity, CSCO is an Equity, SPY is an Index. Lets say thatSPY has one component, AAPL, with shares being 10. (1 share of SPY = 10shares of AAPL).So, I do some trading and I end up with positions as follows:+10 AAPL-5 CSCO+2 SPYThe query I need returns:+10 AAPL-5 CSCO+2 SPY+20 AAPL (from 2 SPY * 10 shares)which becomes (after grouping):+30 AAPL-5 CSCO+2 SPY-----------------------------------------Based on that criteria and the following schema (and sample data):-- Drop tablesDROP TABLE [SecurityMaster]DROP TABLE [Position]DROP TABLE [IndexComponent]-- Create tablesCREATE TABLE [SecurityMaster] ([Symbol] VARCHAR(10), [SecurityType] VARCHAR(10))CREATE TABLE [Position] ([Account] VARCHAR(10), [Symbol] VARCHAR(10), [Position] INT)CREATE TABLE [IndexComponent] ([IndexSymbol] VARCHAR(10), [ComponentSymbol] VARCHAR(10), [Shares] INT)--Populate tablesINSERT INTO [SecurityMaster] VALUES ('AAPL', 'Equity')INSERT INTO [SecurityMaster] VALUES ('MSFT', 'Equity')INSERT INTO [SecurityMaster] VALUES ('MNTAM', 'Option')INSERT INTO [SecurityMaster] VALUES ('CSCO', 'Equity')INSERT INTO [SecurityMaster] VALUES ('SPY', 'Index')INSERT INTO [Position] VALUES ('001', 'AAPL', 10)INSERT INTO [Position] VALUES ('001', 'MSFT', -5)INSERT INTO [Position] VALUES ('001', 'CSCO', 10)INSERT INTO [Position] VALUES ('001', 'SPY', 15)INSERT INTO [Position] VALUES ('001', 'QQQQ', 21)INSERT INTO [Position] VALUES ('002', 'MNTAM', 10)INSERT INTO [Position] VALUES ('002', 'APPL', 20)INSERT INTO [Position] VALUES ('003', 'SPY', -2)INSERT INTO [IndexComponent] VALUES ('SPY', 'AAPL', 25)INSERT INTO [IndexComponent] VALUES ('SPY', 'CSCO', 50)INSERT INTO [IndexComponent] VALUES ('QQQQ', 'AAPL', 33)-- *****************************-- Based on the rules:-- 1) Index positions appear like other positions (account /symbol) pair, but-- its components show up as new rows of account (of index),symbol (equal--to component symbol), position (equal to shares * index position)-- 2) One row for each account / symbol pair (GROUP BY account andsymbol, SUM position)-- Expected output (without grouping) (sorted by account / symbol)-- 001 AAPL 10-- 001 AAPL 375 (component shares * index position) (25* 15) (SPY)-- 001 AAPL 693 (component shares * index position) (33* 21) (QQQQ)-- 001 CSCO 10-- 001 CSCO 750 (component shares * index position) (50* 15) (SPY)-- 001 MSFT -5-- 001 QQQQ 21-- 001 SPY 15-- 002 AAPL 20-- 002 MNTAM 10-- 003 AAPL -50 (component shares * index position) (25* -2) (SPY)-- 003 CSCO -100 (component shares * index position) (50* -2) (SPY)-- 003 SPY -2-- Expected output (with grouping account / symbol) (sorted by account/ symbol)-- 001 AAPL 1078-- 001 CSCO 760-- 001 MSFT -5-- 001 QQQQ 21-- 001 SPY 15-- 002 AAPL 20-- 002 MNTAM 10-- 003 AAPL -50-- 003 CSCO -100-- 003 SPY -2---------------------------------------------Is a UNION the best way to perform the query.

Thanks for the help on the previous thread.
It seems to me that either by accident or design, SQL Server tends to steer you away from backing up directly over the network.
Are there reasons for not doing this because you obviously don't want to leave your backups on a local drive in case the drive fails?
Some possibilties that I can think of are:-
1. Local drives have faster access times and SQL backups can get quite large. I did a quick test and found that a netwrok backup takes 2 to 3 times longer than it does on a local drive.
2. Backing up on the netwrok could hog too much bandwidth. I haven't tested this and would be surprised it it's true.
3. There could be some reason that you don't want the Server and Agent services running under a domain account but want to leave them on the Local System account. I am not aware of any such reasons by the way.
4. Local drives persumably have a slightly higher availability than network drives. If the server is running, the drive should be available.

Like in the subject: What are the cons and pros of using nvarchar(max) versus ntext?
Does it have something to do with having to enable full text search perhaps in the latter case?

I'm just wondering what any pros and cons of using multivalue columns in a database are.
I'm designing a database which will have a column for FABRIC_TYPES_AVAILABLE for a certain FURNITURE_ITEM. Each FURNITURE_ITEM can have multiple FABRIC_TYPES_AVAILABLE of course. So I was just going to store a 2 or 3 digit number of the FABRIC_TYPES_AVAILABLE in that row. So I would have something like....34,24,453,32,23,45,67,65,43,21,21,45.
Anyway....thanks in advance for any information. Links I could read would be great too...b/c I did do a bit of searching, but didnt find much.

I have a main database...for this large Web site...and Im wondering
what would be the PROS and CONS of using another database (located on
the same, or on another SQL Server). Im just thinking this would be
good incase we ever needed to take some load off one of the servers.
Also, we will be integrating Community Server into this Web site. Of
course you know CS adds its own database objects which crowd up our
main database objects.
We were thinking of giving CS its own database also; bad practice, or....it doesn't matter much?
Thank you

Are there any vices to using default constraints on all columns in your table.
For example an Int that defaults to 0
or a char or varchar that defaults to ''
I know that 0 and Null are not the same thing. But if your programs don't have the concept of NULL then you have to convert the NULL to zero.
So, DEFAULT CONSTRAINTS on every column. Is it good or Bad?
Thanks

Can someone provide information or a link to information regarding the pros and cons of saving files directly into a SQL 2005 database?
I'm actually for saving files to a database (cleaner implementation then just saving the location then having to get the file, etc), but my project manager is not convinced so I need to make an argument for (or against depending on what I actually find out) using varbinary data type.
Thanks.

I was wondering if anyone knows of any pros/cons on storing SSIS (2005) packages within SQL Server 2005 SP2.
We're contemplating the migration/storage of a large number of packages, a minority of which designed in dts (SQLServer 2000) and using third party activx components.

We are in the process of replacing our primary production server. In the process of determining how SQL server is going to be structured, it has been suggested that I place all current and new indexes on a separate file group. These filegroups would then reside on a separate shelf on the server. What are the pros and cons of doing this?

I am using transaction replication between a transaction and reporting database server. When I use a snapshot to initialize my subscribers, I currently get a lot of deadlocks during the snapshot creation. I am considering using a database backup instead. Can anyone tells me how to reduce the table locks that I am getting during snapshot creation or advice on using database backups?

Let's say I have a trigger on my orders table.
When this fires a query is done on the customer table to get some values
and put some order/customer data into an audit trail table.
In one period of time, it appears that the trigger did not put the data into the separate table. No known reason.
Suspicion: What if the customer table were locked by some process when the trigger fired. Maybe the trigger was chosen as a deadlock-victim.
?? I guess I need to check for @@ERROR during the trigger and do something. Any suggestions? I think I can raise the priority of my trigger to "win" during a deadlock.
If trigger activity is chosen as a deadlock-victim, can the trigger make another attempt to complete it's activity?

Hi,
I am using UNIQUEIDENTIFIER column for my table. I do not insert data for it. I left it on database by setting to default NEWID(). Now in my application I need the value of UNIQUEIDENTIFIER column I just inserted. Is there any function or query to get this value like in case of IDENTITY column we can get the latest inserted value from select @@IDENTITY.
Thanks and regards,
Uday

I have a table with id(uniqueidentifier) as the primary key, and another table with id(int) as the foreign key.
When I try to INNER JOIN them on id=id in a view, I get an error that uniqueidentifier and int are incompatible.
I'm new to SQL SERVER and I consider uniqueidentifier as equal to AutoNumber in MSAccess. Isn't it so? If not, how do I make this JOIN work?

Stored Proc.
CREATE PROCEDURE proc_CustomerCheckExist@UserId uniqueidentifierASIF EXISTS (SELECT COUNT(*) FROM dbo.aspnet_LD_Customers WHERE UserId = @UserId) Return 1ELSE Return 0GO
Problem is if I take 2 different GUID, I still get the same result "Return 1" as true even if I dont have the GUID in my tabel row

Hello there!
it was a while since i studied SQL and that brings us to my problem...
I'm creating a Stored Procedure wich first insert information in a table. That table has a uniqueidentifier fild that is default-set to newid().
later in the SP i need that uniqueidentifier value? how do I get it?
I tried this:
CREATE PROCEDURE spInsertNews
@uidArticleId uniqueidentifier = newid,
@strHeader nvarchar(300),
@strAbstract nvarchar(600),
@strText nvarchar(4000),
@dtDate datetime,
@dtDateStart datetime,
@dtDateStop datetime,
@strAuthor nvarchar(200),
@strAuthorEmail nvarchar(200),
@strKeywords nvarchar(400),
@strCategoryName nvarchar(200) = 'nyhet'
AS
INSERT INTO tblArticles
VALUES( @uidArticleId,@strHeader,@strAbstract,@strText,@dt
Date,@dtDateStart,@dtDateStop,@strAuthor,@strAutho
rEmail,@strKeywords)
declare @uidCategoryId uniqueidentifier
EXEC spGetCategoryId @strCategoryName, @uidCategoryId OUTPUT
INSERT INTO tblArticleCategory(uidArticleId, uidCategoryId)
VALUES(@uidArticleId, @uidCategoryId)
But i get an error when I EXEC the SP like this:
EXEC spInsertNews
@strHeader = 'Detta är den andra nyheten',
@strAbstract = 'dn första insatt med sp:n',
@strText = 'här kommer hela nyhetstexten att stå. Här får det plats 2000 tecken, dvs fler än vad jag orkar skriva nu...',
@dtDate = '2003-01-01',
@dtDateStart = '2003-01-01',
@dtDateStop = '2004-01-01',
@strAuthor = 'David N',
@strAuthorEmail = 'david@davi.com',
@strKeywords = 'nyhet, blajblaj, blaj'
the errormessage is: Syntax error converting from a character string to uniqueidentifier.
does anyone have a sulution to this problem?
Can I use something similar to the @@IDENTITY?
I will be greatful for any ideas...
thanks

Hi,
I am writing a C# application that uses a SQL server database to hold its data. I need to create a stored procedure that returns a particular row's primary key value. This is no problem if the primary key is an INT. But my primary key is a unique identifier, and the stored procedure doesn't want to let me return any values that aren't INTs. Can someone please tell me how to get around this?

Hello everyone.
I have 2 tables in MSSQL Server 2000, Products(idProduct, idProductType, name, quatity) and ProductsType(idProductType, name).
idXXXX are the primery keys and the data type is uniqueidentifier.
In table Products, the collum idProductType is a foreign key refering table ProductsType.
I can insert as many product types as i want without any problems.
Insert INTO ProductsType(name) VALUES('milk')
When inserting products i use the idProductType that was automatacly generated in last insert.
INSERT INTO Products (uuidProductType,name,quantity,)
VALUES ('AD9388A3-CA86-482D-B57F-6FA068E7D405','President Milk 50cl',500)
but i got the following error in SQL Query Analyzer:
Server: Msg 8169, Level 16, State 2, Line 1
Syntax error converting from a character string to uniqueidentifier.
I have searched the forum and i cant find any solution. i need to use uniqueidentifer data types because replication with PDA devices.
Any tips?
Thank you in advance.
Helder
