Re-populate A Unique Number Into Multiple Fields
Oct 14, 2004What I need to do is re-populate a unique number into multiple fields,
Let me explain, An employee can appear in the first table only once but can be in the second table multiple times with multiple employee numbers .There is a field called TFN that is unique and we are using it to create a unique id called KRid so what I have done is created 2 tables namely TEST_TBL and TEST2_TBL . In TEST_TBL I am populating a KRid with a unique no being produced by the TFN field only once i.e 12345 being the resulting unique id number. If an employee has 2 employee numbers i.e empno 1 and empno 1000,only employee no 1 will have the unique KRid created but nothing for 1000 because the record already exists , so what has me stumped is that the TFN for employee empno 1 and the TFN for empno 1000 are the same. How do I get the KRid (12345 from empno 1) to populate empno 1000 in TEST2_TBL , The second table has all records in so I can group the second table by TFN id but how do I populate employee 1000 in the second table with the KRid 12345.
Please help!!!!! Below are how the tables are set up and an example of the result.
TABLE 1
if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[TEST_TBL]') and OBJECTPROPERTY(id, N'IsUserTable') = 1)
drop table [dbo].[TEST_TBL]
GO
CREATE TABLE [dbo].[TEST_TBL] (
[Empl_Num] [char] (32) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ,
[Surname] [char] (32) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ,
[First_Name] [char] (32) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ,

[TFN] [char] (32) COLLATE Latin1_General_CI_AS NULL ,
[Date_Term] [datetime] NULL ,
[Empl_Type] [int] NULL ,
[Cost_Centre] [char] (32) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ,
[Empl_Status] [int] NULL
) ON [PRIMARY]
GO
TABLE 2
if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[TEST2_TBL]') and OBJECTPROPERTY(id, N'IsUserTable') = 1)
drop table [dbo].[TEST2_TBL]
GO
CREATE TABLE [dbo].[TEST2_TBL] (
[EmpNumber] [char] (32) COLLATE Latin1_General_CI_AS NULL ,
[TFN] [char] (32) COLLATE Latin1_General_CI_AS NULL ,
[KR_ID] [char] (10) COLLATE Latin1_General_CI_AS NULL ,
[EmpStatus] [int] NULL ,
[EmpType] [int] NULL ,
[CommonName] [char] (32) COLLATE Latin1_General_CI_AS NULL
) ON [PRIMARY]
GO
Query goes as follows for table 1:
SELECT NPE000.EmpNumber, NPET00.RecordStatus, NPE000.KR_ID, NPE000.Surname, NPE000.FirstName, NPE000.SecondName, NPE000.Class, NPE000.DateEmployed, NPE000.DateOfBirth, NPE000.HoursPerDay, NPE000.HoursPerWeek, NPE000.PassportNo, NPE000.AwardCode, NPE000.EmailPayslipTo, NPE000.Location, NPE000.Grade, NPE000.DateTerminated, NPE000.EmploymentType, NPE000.DistCode, NPE000.EmpStatus, NPET00.TaxRefNo FROM NPE000 NPE000, NPET00 NPET00 WHERE NPET00.RecordStatus = 0 and NPET00.TaxRefNo <> ' 111111111' and NPET00.TaxRefNo <> ' 000000000' AND LENGTH(NPET00.TaxRefNo) >= 9 AND LENGTH(NPE000.KR_ID) >= 0 AND NPE000.EmpNumber = NPET00.EmpNumber
Query goes as follows for table 2:
SELECT NPE000.EmpNumber, NPE000.FirstName, NPE000.Surname, NPE000.Class, NPE000.Location, NPE000.EmploymentType, NPE000.EmpStatus, NPET00.TaxRefNo, NPE000.Paypoint, NPE000.KR_ID, FROM NPE000, NPET00 WHERE Recordstatus = 0 and (EmploymentType = 1 AND EmpStatus = 1 AND NPE000.EmpNumber = NPET00.EmpNumber
From this you can see that in table 1 it will only create 1 KR_ID for only one employee number but in table 2 I am bringing through all employee records. In table 2 I can group by NPET00.TaxRefNo which will bring all NPET00.TaxRefNo's togeather. From that I would like to populate the other employee numbers with the unique KR_ID.
Example:Table 1
000001,Jackson,James,Sam,7.6,38,12345,475431212
Example:Table 2
000001,Jackson,James,Sam,7.6,38,12345,475431212
001000,Jackson,James,Sam,7.6,38,,475431212
I hope this helps
Thanks in advance
Unique Identifier
Jan 19, 2005I'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, 2007I 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?

SQL Server 2012 :: Unique Identifier As Identity Field
Dec 27, 2013So 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...

Master Data Services :: Unique Identifier In MDM Profisee Stage Table
Apr 13, 2015I 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?
Replic From Multiple Clients: Identifier Conflicts
Mar 29, 2007I think I will have a problem with Id’s when I do merge replication. The problem is, I have several clients (local shops) who can do additions to a (Customer) table. Other tables will link to that table (things that a customer buys) with their foreign key, so the id of this table is very important. Now, twice a day that table with customers is merged from all clients to the central server. (the table with things that the customer buys, does not needs to be merged as it only remains local).
Possible problem:
if we assign ranges to identifiers for each client (thus local shop), which will be the best option we found until so far, how can we then detect the doubles? (with doubles, we mean that when the same customer is added in two local shops for a first time, then we will have the same customer twice in the central database)(afterwards, when we delete one customer row in the central database, we might have a id conflict when we merge back to the clients -as a customer might have already bought some goods at the two different shops meanwhile-)
What’s the common practice to resolve this?
(we need to do Merge Replication, because during the day, our local shops are disconnected from the central server)

InstructorName varchar(255) NOT NULL,
CourseName varchar(100) NOT NULL,
DataTableName varchar(100) NOT NULL

constraint syntax:
Code:
Alter Table Employees
Contstraint uniqueEmployee Unique (InstructorName ,CourseName ,DataTableName )
