Unique PK In Each Table

Oct 30, 2006

Let say I have 6 tables. I want to autogenerate the PK for each table and that is unique for each table and cant be duplicated on other tables. Let say I have table with PK of 1, so table2 to table6 wouldnt have a PK of 1. If table2 have a PK of 2, table1, table3 to table6 wouldnt have a PK of 2. Same for others. Identity will not be appropriate.  Will 'uniqueidentifier' data type suffice? How bout guid? Or what must be my datatype? Or what will I do to implement this? Any links? Thanks

Integration Services :: Load Incremental Data Into Fact Table When Source Table Not Have Timestamp And Unique Key

Sep 24, 2015

I have a transaction table having about 40 crore rows in source. It don't have timestamp and unique key columns. It have only Bill_month and Bill_Year columns. Actually for loading this table into staging I have added a new datetime column by adding default bill_date as 01. Then

* First we delete last 3 month data from staging tables.
* Get last 3 months data from source table.
* Load that 3 months data from source to staging table. 

We do this because we only get update for last three months data. Now I have to include this transaction table as Fact table in DW. What will be the best practice for loading the fact table by picking data form staging table. Also we have to look up with dimensions for Foreign Keys. 

* Should I implement the same method of deleting last 3 months records and loading them again.

Help Me Getting A Unique Combination From Table

Jun 18, 2004

Hi, I have following table

BetId GameId
==== ======
500 108
500 109
501 108
501 109
501 110
502 108
502 109

My query would have the form: select BetId where GameId in(108,109)
from Bets then it has to get me BetId : 500 and 502.
Not 501,since this is different combination(108,109,110) ;)

A Table With A Unique Field

Jul 10, 2007

Hello,

I would like to store some frequently asked questions in a database.
As those questions/answers could be translated in several languages, I was thinking of using two tables :

The first table would contain a unique field : the key wich is an id for each faq.

The second table would contain those fields :
FAQ_ID : foreign key
LANG : language
QUESTION : the question translated in the good language.
ANSWER : the answer translated in the good language.

What I find embarrassing, is that first table just contains a unique field : the id. But it allows :
- to have a table in which a line correspond to an object. It is convenient for object relational mapping.
- it is more evolutionary. If, in the future, I have to add some statistics that concerns a faq, I will have the possibility to store them in the first table, avoiding in this way to duplicate data.

But, one more time, I find a bit embarrassing having a table with a unique field...

What is your opinion about that ?

Thank you in advance for any suggestion.

Append Only Unique Records In SQL Table

Nov 23, 2007

I have a stored procedure that appends data from a temp table to a destination table.  The procedure is called from an aspx web page. The destination table has an index on certain fields so as to not allow duplicates.
The issue I'm having is if the imported data contains some records that are unique and some that would be duplicate, the procedure stops and no records are appended. How can I have this procedure complete it's run, passing over the duplicates and appending the unique records? Since the data is in a temp table (which gets deleted after each append) should I run some sort of 'find duplicates' query, and delete the duplicates from the temp table first, then append to the destination table?
Thanks in advance.SMc

Unique Counter Field In A Table - Best Way?

Oct 11, 2005

I need to to have a table that has a counter field (used to generate an id code for a record).  This is not the primary id for the field but just a counter to label a record in another table, similar to a registration code for an event.  This is a sequential counter that will start 1 and go up on each new record inserted into other tables.  What I want to do is be able to query this counter table to get the next valid number and increment the count for the next time.  This is a multi user web app so needs to prevent duplicate use of same number.How best should this be handled?  A transaction to query and update the field?

New Unique Number In History Table

May 23, 2008

Hello,
I am using SQL Server 2005 and am having trouble with making a history table like mentioned in my earlier thread:

http://www.sqlteam.com/forums/topic.asp?TOPIC_ID=102811

This is the table "People" I have created:

|PersonId (PK)|DateFrom (PK)|DateTo|PersonName|Other Attributes....

Each change to a person's attributes results in a new row formed with the same PersonId as in the row with old attributes and the Date these new attributes are valid (DateFrom). So as shown above the Primary Key is a combination of the PersonId and DateFrom as a change to a person's attributes should never happen at the same time twice.

My problem is when I want to create a new person, how do I get a new unique id? Ideally I want the a new incremented id, so that all peoples' ids are in a sequential order.

As always, thanks for the help!

Unique Constraint To A Column From Another Table

Oct 29, 2005

Is it possible to create a unique constraint to a column from anothertable? For example:tb_current:current_names--------------aaabbbtb_new:new_name--------cccNow I want to create a constraint on tb_new.new_name to be unique withrespect to tb_current.current_names. However, tb_new.new_name shouldnot be unique to itself. So I should not be able to insert 'aaa' totb_new.new_name. But I should be able to insert 'ccc' totb_new.new_name.Here's the script to reproduce this example:create table tb_current(current_names varchar(10))create table tb_new(new_name varchar(10))insert tb_current values ('aaa')insert tb_current values ('bbb')insert tb_new values ('ccc')select * from tb_currentselect * from tb_newinsert tb_new values ('aaa') -- this should NOT be allowedinsert tb_new values ('ccc') -- this should be allowed

How To Force Unique Entries In A Linking Table?

Jul 20, 2005

I have a table 'Group2Operation' that stores many to many relationsbetween the 'Group' table and the 'Operation' table (each group is haspermission to perform one or more of the available operations)PROBLEM=======I need to prevent duplicate entries being created. e.g. lets say thatin the 'Group2Operation' table a record links the 'editor' group tothe 'publish' operation. Should I prevent an administrator creating aduplicate of that record? (Otherwise deleting that permission willhave to be done twice or more for it to be effective)SOLUTION?=========So far I've done this with a trigger:CREATE TRIGGER Group2OperationDuplicates ON dbo.Group2OperationFOR INSERT, UPDATEAS UPDATE Group2OperationSET NoDuplicate = CONVERT(nvarchar(10),GroupID) + OperationTagThe 'NoDuplicate' unique index column in the Group2Operation tablestores a concatenation of the unique group and operation identifiers.So when an attempt is made to create a record, the trigger is fired.If there is a duplicate, this will mean a duplicate entry in the'NoDuplicate' column. As a result, the INSERT or UPDATE will fail andthe duplication will be prevented.WHAT DO YOU THINK?==================What do you think? Am I going about this in the right way? Is atrigger a good way to do this or should I rely on application logic toprevent duplicates?Any help appreciated by this db novice.John Grist

Inserts And Updates To A Table That Contains A Unique Key Constraint

Nov 5, 2007

I am looking for pros and cons for the following scenarios:

When a table contains a unique key constraint is it viable to always do an insert and immediately check the @@ERROR value and if @@ERROR states a duplicate key exception then perform an update statement?

Another possible solution would be to always check if the key exists and then do the insert / update based upon that result. This method will always require two steps.

    -- Insert statements for procedure hereSELECT     tbl_Queue.num_TicketNumber AS TicketID , tbl_Users.str_Name AS Technician , tbl_Queue.str_QueueLocator AS TechNTID , tbl_Queue.dat_ReceivedRequest AS dateCreated , tbl_Queue.dat_DueDate AS DueDate , tbl_Queue.str_TaskName AS TicketTitle , tbl_Queue.str_Requestor AS RequestorNTID --, I need most current dat_TimeStamp from tbl_Notes here for this record --, I need most current int_PercentComplete from tbl_Notes here for this record --, I need to sum up all of int_MinutesWorked fields from tbl_Notes here for this record , MasterEmp.dbo.fn_FormatFullName(tbl_employee.str_fname, tbl_employee.str_lname) AS RequestorName , tbl_Queue.str_TicketType AS TicketType , tbl_Status.str_TaskStatus AS TicketStatus , tbl_Severity.str_Priority , tbl_Complexity.str_Complexity , tbl_Severity.str_Priority + N' / ' + tbl_Complexity.str_Complexity AS Priority , tbl_Queue.dat_CompleteDate as DateCompleted 
FROM          dbo.tbl_Queue LEFT OUTER JOIN MasterEmp.dbo.tbl_employee AS tbl_employee ON dbo.tbl_Queue.str_Requestor = tbl_employee.str_ntid LEFT OUTER JOIN tbl_Users ON  tbl_Queue.str_QueueLocator = tbl_Users.str_ntid LEFT OUTER JOIN tbl_Status ON  tbl_Queue.num_Status_CD = tbl_Status.num_Status_CD LEFT OUTER JOIN tbl_Severity  ON tbl_Queue.str_Severity = tbl_Severity.str_Severity LEFT OUTER JOIN tbl_Complexity  ON  tbl_Queue.int_ComplexID = tbl_Complexity.int_ComplexID
WHERE      (dbo.tbl_Queue.dat_ReceivedRequest > CONVERT(DATETIME, @DateCreated, 102))   
 ORDER BY     TicketType,     tbl_Queue.str_Severity
I also have another table called tbl_Notes.  This table contains an unlimited quantity of records for every “num_TicketNumberâ€?.  This table contains the following fields:  num_TicketNumber, str_TechRep, str_Notes, dat_TimeStamp, int_PercentComplete and int_MinutesWorked
I need to add two more fields to the query, but I do not know how to tell the SQL statement how to retrieve the data for the specfic record and inbed the fields into the Dataset being returned from the database to the web page.1) The first field I need is the most current recorded Date field from the tbl_Notes table for the each of the records returned in the above SQL statement.  Similar to:  SELECT TOP (1) dat_TimeStamp FROM tbl_Notes WHERE(num_TicketNumber = xxxx) ORDER BY dat_TimeStamp DESC2) The other field I need to return with the Dataset is the sum of the int_MinutesWorked for each of the tickets being retrieved. Similar to:  SELECT SUM(int_MinutesWorked) AS TotalMinutesFROM tbl_Notes WHERE (num_TicketNumber = 49)

Need Help W/ SELECT From One Table, One Field, Multiple Unique Records

Apr 22, 2006

I'm new to MS SQL and VB. I have a table with one field JOB_NAME containing 20 records. Out of that field I want to retrieve 6 of the 20 records into a pulldown menu. They are all unique text names like so:

Anna Smith
John Doe

etc. I did not see IDs listed for any of the names in the table when I looked.

There is no common denominator to the names that can be filtered in the SELECT statement, and the 6 that I want will need to be pulled out individually.

Is there a way to do this with a SELECT statement? I have not found much information about how to extract unique records out of a single field. Here's the statement I'm using which pulls all of them:

strSQL = "SELECT DISTINCT JOB_NAME AS Names FROM [WORKER_NAMES] WHERE JOB_NAME<>' ' ORDER BY JOB_NAME ASC"

This gives me the total list but I only want to bring back 6 of the 20 for the pulldown.

Is there a way to modify this statement to pull only the records that I want?

Thanks for any help you can give.

AJ
