Disadvantages Of Using Uniqueidentifier (Tell Your Tale)
Nov 19, 2003
Dear SQL...
I'm about to use uniqueidentifier and NEWID() for my new DB,
The DB may grow wild and I want to super safely create connections between tables,
so it would not just rely on numbers (that can B changed) as used with IDENTITY...
If U had some BAD experience with this or if U have any tips I can use please let me know
+
Should I take any special steps when using index on it ?

hi,
i am thinking of using autonumber in my table which is more likely to grow over time. but i am also concerned that what if the records get too much? is there is any other fields to use instead of autonumber? is uniqueidentifier a better option? i have a bit of discussion with my colleague about this matter.
any help is appreciated

I have a content site where everything is currently in one SQL ServerDB. As I add features to the site, for example message boards andblogging, does it make sense to put those features in a separatedatabase? What would I lose and gain in doing so? Thanks so much.Erik

Are they're any real disadvantages or advantages in having 1 massive disk partioned to create 2 logical drives (not including the C drive) and separating the SQL Database File & Transaction Log so that it doesnt reside on the same logical drive?
After all, it is still a single disk.
thanks.

I have a hosted solution where the web host provider tells me I'm running on a 2005 platform, but when I check the DB options, it shows compatibility level 80. The provider tells me I'm not losing any performance by running in the lower compatibility mode. Is this truly the case? What else am I losing out on in terms of features or capabilities?

Dear Sirs and Madams,
it's quite hard to find informations about OLAP mining I think. So I have some questions to you:
What advantages do I have by using Olap Mining instead of "normal" mining (relational databases)?
Is it just faster or are there other advantages?
What are the disadvantages? The data can be overaggregated (no detailled results), can not? Are there other disadvantages?
What problem do I have to face?
Whats going on with empty cells?
Thank you very much in advance and have a nice weekend.

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

Hey I was curious about the Uniqueidentifier is that better then using the @IDENTITY, apparently the Unique uses your computers mac address as a base???

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?

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?
Thanks in advance.

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.

The funny thing is that i copied the sp code from another which runs perfect,
I insert a Guid from an asp.net page.
Hope someone can help me here because im am stucked!
