Unique Identifier

Jan 19, 2005

I'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,

Database Catalog Unique Identifier

Jan 4, 2007

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?

Storing GUID (global Unique Identifier)

Feb 9, 2005

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?

SQL Server 2012 :: Unique Identifier As Identity Field

Dec 27, 2013

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...

How To Convert SQL Unique Identifier In A Csv File To A SSIS GUID Variable

Aug 21, 2007

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!

Master Data Services :: Unique Identifier In MDM Profisee Stage Table

Apr 13, 2015

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?

Using Membership UserId Guids With SqlParameters (Membership UserId Guid)

May 7, 2008

In my site, when a user registers, I need to create rows in additional tables besides aspnet_Users. So, I need to be able to pass the generated userId guid to subsequent SqlCommands. I'm having a terrible time with this. What's the correct way to set up a SqlParameter so that it will accept a guid? I keep getting this error: "Conversion failed when converting from a character string to uniqueidentifier."
I've tried creating the parameter both with and without a SqlDbType.
cmd.Parameters.AddWithValue(paramName, guid);
and
SqlParameter p = new SqlParameter(paramName);p.SqlDbType = SqlDbType.Guid;cmd.Parameters.Add(p);
and I get the same error either way.
Driving me nuts! Any help appreciated.

Relationship To UserId

Nov 22, 2006

Hi there everyone, this is my first post so go easy on me :)
Basically I am trying to get my database to copy the value in the UserId (unique identifier field) from the aspnet_Users table to a foreign key UserId in a table called userclassset. I have made this field the same datatype and created a relationship between the two. Unfortunately, when I add a user using the ASP.Net configuration tool it does not automatically copy this value into my own custom table. I have noticed it is however automatically copied into the aspnet_Membership table. Any pointers on how to solve this would be great!
 Thanks :)
