Function GUID() As String
GUID = System.GUID.NewGuid().ToString()
End Function
GUID is always 36 characters, for example:
1737be72-fe96-4c3c-b455-3730b049bef9
What the best way to store this in a MS SQL database? I'm thinking of using a fixed length string (char). Is there a better way than to just store this 36 character field?
Here's a problem description I read on another post but I have the same issue:
I am trying to Import Data from a csv file into a SQL Sever table. The Data being imported has a Unique Identifier in it but it is being considered as DT_WSTR datatype in SSIS
When i directly try to import, it gives an error:
The conversion returned status value 2 and status text "The value could not be converted because of a potential loss of data.".
I Tried to use Data Conversion to convert it to DT_GUID and import into SQL Server table but it again throws the above error.
Anyone has a clue?
Thanks!
Is it possible to reference a temporary global tale (##table) of a linked server using the 4 parts "identifier": linkedserver.database.schema_name.##object_name ??
Thanks in advance for your help.
Greetings All, I have read many upon many articles here regarding GUIDdata types and uniqueness. There have been many opinions regardingthe effectiveness of GUID's and when they should/should not be used.However, every article strongly implies, if it does not state itoutright, that GUID's are always unique. My question is this, whathappens if you have a database that uses GUID's and the NIC is changedout on the box? From what I understand the MAC address of the NIC isused as part of the algorithm to generate a GUID. If you change outthe NIC after generating 1 billion GUID's do you run the chance ofgenerating a duplicate GUID?I look forward to your insightfulness on this issue.Regards, Louis.
View 4 Replies View RelatedI'm trying to create a unique identifier number that meets the following criteria. The unique identifier needs to be a concatenation of two values submitted from a form and the identity value (primary key) for the new record that is inserted into the database.
So, if the first field is the year and the second field is a objnumber, the unique identifier number would have the format: ("YR" + "objnumber" + primary key value), where the year and object number are what the user selected in the form.
I have a stored procedure that I use to handle the insert, which also returns @@identity for the purpose of passing that value into another stored procedure that inserts child records.
So, within my stored procedure, is there a way I can create the unique identifier number and return that value back to the application? I'm not sure how to accomplish this?
Here is my stored procedure:
CREATE PROCEDURE dbo.REQ_HDR_INSERT
@ddo varchar(50) = null,
@requestor varchar(100) = null,
@dt datetime = null,
@abrtype varchar(20) = null,
@subject varchar(250) = null,
@description varchar(500) = null,
@review char(10) = null,
@ay char(4) = null,
@origallo varchar(50) = null,
@reqallo varchar(50) = null,
@logl_del_dt datetime = null,
@phys_del_dt datetime = null
AS
Insert into dbo.DIM_ABR_REQ_HDR (ABR_ddo, ABR_requestor, ABR_dt, ABR_type, ABR_subject, ABR_description, ABR_review, ABR_AY, ABR_orig_fund_allo, ABR_req_fund_allo, ABR_LOGL_DEL_DT, ABR_PHYS_DEL_DT)
values (UPPER(@ddo), UPPER(@requestor), @dt, UPPER(@abrtype), UPPER(@subject), UPPER(@description), UPPER(@review), @ay, convert(money, @origallo), convert(money, @reqallo), @logl_del_dt, @phys_del_dt)
return @@identity
GO
I would be using @ay and @ddo as the first two parts of the unique identifier number. Any help is appreciated.
Thank you,

How can i get a numer for using it as unique identifier in two related tables?
View 3 Replies View RelatedLet's say that I have a database with 2 tables named 'TableA' and 'TableB'. Each one of those two tables contains the two fields 'MyKey' and 'MyData'. The field 'MyKey' has the type 'uniqueidentifier' and its default value is 'getnewid()'.
Now I would like to consider a third table named 'TableC' with two fields 'KeyRef' and 'MetaData'. The type of 'KeyRef' is 'uniqueidenfier' and corresponds to an element of either 'TableA' or 'TableB'.
If the GUID identifiers are trully unique then there is no issue to proceed that way (I am not consering perf matters here). On the contrary, if GUID are not unique, then there is a collision possibility.
My question is simply: can I consider the GUID to be unique in MS SQL Server (2000 or 2005).
Thanks in advance,

I need to develop a strong licensing solution based on the database accessed...
Currently our solution is easily hackable because the the license information is kept in the database of your choice and is not dependant on some static information, the current encryption key is static and kept in the software so it can be hacked easily. What i want to do to change this is simple in nature but i don't know how to get that one particular info i need.
I want to get some kind of unique identifier for a database (catalog) that sql server could generate. This info must be static and must not be movable. If for example, someone would backup and restore, this information would not be transfered with the backup. Thus, a user that backups his database and restores it on another database server or another database catalog even on the same server would corrupt his license since the Unique ID returned by the SQL Server would be different; the hashing code would change and thus the decryption would fail.
Is there any such info i can query using SQL that will not require admin rights?
Please see below post

I'm migrating a web based system to SQL server. I'm planning on using the SQL server function NewID() to create unique keys for many of my records in many different tables. I'm just wondering if NewID() is guaranteed to return a value that does not already exist in my database. I mean obviously once you have a certain number of records (a hell of a lot) you'd be breaking the odds to never come up with a duplicate. Do I need to make sure the result of NEWID() doesn't already exist?Thanks
View 1 Replies View RelatedI've googled everything about GUID, seems there is no good thing to say about it. Here's my scenario, a purchase order (PO) application:
We want to have a centralized database with remote sites connected to it
Some of the sites are without connection, they will have their own servers with scheduled replication to the centralized database.
The design is something like this:
Each PO will have many revisions
Each revision will have many PO line items
Each PO line item will have many Delivery Schedules
In the past i used int IDENTITY as transaction ID in revision and line item tables.
transaction ID in revision table is FK to line item table, and transaction ID line item table is FK to Delivery Schedules table.
This work well in standalone database.
Now that we need to merge replicates, int IDENTITY produced in remote DB will conflict with IDENTITY produced in central DB.
I'm thinking of using GUID to replace int IDENTITY.
Question:
How bad is my decision?
Can't GUID size indexing problem be solved with partitioning?
Can you suggest other alternatives to GUID, based on the above scenario?
Thanks in advance

Hi,
I need a resolution of the following issue:
Following SQL is to be inserted in an audit table :
INSERT INTO GLOBAL_VARIABLE_LOAD
([LOAD_ID]
,[LOAD_STATUS]
,[START_TIME]
,[END_TIME])
VALUES
(@P_LOAD_ID
,@P_LOAD_STATUS
,@P_START_TIME
,@P_END_TIME)
@P_LOAD_ID, @P_LOAD_STATUS, @P_START_TIME, @P_END_TIME are the 4 parameters mapped to global variables (At package Level) which store values mapped in a previous SQL Task in my control flow.
Following Error Message is thrown on executing the SQL Task:
Invalid object name 'GLOBAL_VARIABLE_LOAD'.". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.
Can anyone guide me as to how should I go about saving values in global variables and inserting them in a table.
Thanks in advance.

So for years I was using the int identity(1,1) primary_key for all the tables I created, and then in this project I decided, you know, I like the uniqueidentifier using newsequentialid() to ensure a distinctly unique primary key.
then, after working with the php sqlsrv driver, I realized huh, no matter what, i am unable to retrieve the scope_identity() of the insert
So of course I cruised back to the MSSMS and realized crap, I can't even make the uniqueidentifier an identity.
So now I'm wondering 2 things...
1: Can I short cut and pull the uniqueidentifier of a newly inserted record, even though the scope_identity() will return null or
2: do I now have to add a column to each table, keep the uniqueidentifier (as all my tables are unified by that relationship) and also add a pk field as an int identity(1,1) primary_key, in order to be able to pull the scope_identity() on insert...

I am new to MDM profisee tool and currently working for Addres verification project for my organization.I wanted to clear my doubts here about Unique Identifer in Stage table and how it works.. Here what i understand till now:
Step 1) I created an Entity using MDM profisee UI and it generated a stage table in MDS database called stg.Address_leaf
Step 2) I have loaded data from external source to MDS stage table using ETL and passed Import type as 2 and Import status id as 0
Step 3) I have run store procudure system generated something stg.udp_Address_leaf to load the model and passed the version name as Version_1, Log flag as '1' and Batch tag as 'Address'
Now my below are my questions:
1) What is the field i can use in MDS stage table to populate my unique intifier value coming from source? (lets say Address_Id is my Unique value for all the records coming from source)
2) Where/how Unique Identifier is useful in this process? Will this be useful in next time load from stage to Model?
3) If i truncate and load my MDS stage table in next run and few earlier records has been updated how it will update those records in Model? will this process (code present in SP) recognize by Unique Identier column present in MDS stage table?
Hello there,I just want to ask if storing data in dbase is much better than storing it in the file system? Because for one, i am currenlty developing my thesis which uploads a blob.doc file to a web server (currently i'm using the localhost of ASP.NET) then retrieves it from the local hostAlso i want to know if im right at this, the localhost of ASP.NET is the same as the one of a natural web server on the net? Because i'm just thinking of uploading and downloading the files from a web server. Although our thesis defense didn't require us to really upload it on the net, we were advised to use a localhost on our PC's. I'll be just using my local server Is it ok to just use a web server for storing files than a database?
