Referencing A Users Table For History

May 6, 2008

I've recently finished an application for a small company with perhaps two hundred employees. Each employee was set up in a Users table in the database, against which application logins were processed.

For just about every other table in the database, other than pure lookup tables, we created columns to indicate the user who created the entry, and the user who last modified the entry. This was done using FK references back to the Users table. Each table contains two references back to the Users table, and there are over 150 tables now that follow this scheme. At first I was not concerned, other than the fact that it makes a visual picture of the data model look very confusing (almost every table has a pair of links back to the Users table), until I encountered an issue where I could no longer delete from the Users table. Upon surpassing 253 FK references to Users, I can no longer delete users, as the Query Optimizer can't complete the query.

Now, all of that so far is really not a big deal. Deleting users was never my intent anyway. The only real question I have is whether this is the standard way of maintaining history for table records. Have others used this method? Is there a better way?

Connecting Users From ASPNETDB.MDF To A Shopping Cart And Order History

Jan 2, 2007

I'm trying to figure out how to associate users in my ASPNETDB.MDF to create a shopping cart.IE: I have 3 tables, for a list of existing orders, list of products, and list of specific orders.The idea is for users who've signed up with the built-in user creation control, can then place orders from the shopping cart, and view their existing previous orders. This would normally be done with a unique UserID # to associate orders with specific users, however I don't BELIEVE there's anything like UserID's associated with each user in the ASPNETDB.MDF, it just uses usernames as the unique identifiers right?Anyway I'm not sure I'm explaining what I'm trying to do perfectly and I apologize, but I don't think it's an un-common problem I'm having. Basically I'm trying to avoid having to have existing ASPNETDB users create a sort of SECOND user that would associate them into a seperate Customers table, it seems like extra user steps that shouldn't be necessary.

Mind Boggling / How Can You Query Self Referencing Tables? (self Referencing Foreign Keys)

Jun 15, 2006

For example, the table below, has a foreign key (ManagerId) that points to EmployeeId (primary key) of the same table.
-------Employees table--------
EmployeeID  . . . . . . . .  .  .  int
Name  .  .  .  .  .  .  .  .  .  .  .  nvarchar(50)
ManagerID  . . . . . . . .  .  .  .  int
If someone gave you an ID of a manager, and asked you to get him all employee names who directly or indirectly report to this manager.
How can that be achieved?

Transact SQL :: Update Multiple Table Referencing New Table Data

Aug 4, 2015

I have a table called ADSCHL which contains the school_code as Primary key and other two table as

RGDEGR(common field as SCHOOl_code) and RGENRl( Original_school_code) which are refrencing the ADSCHL. if a school_code will be updated both the table RGDEGR (school_code) and RGERNL ( original_schoolcode) has to be updated as well. I have been provided a new data that i have imported to SQL server using SSIS with table name as TESTCEP which has a column name school_code. I have been assigned a task to update the old school_code vale ( ADSCHL) with new school_code ( TESTCEP) and make sure the changes happen across all 3 tables.

I tried using Merge Update function not sure if this is going to work.

Update dbo.ADSCHL

Delete Rows In One Table By Referencing Another Table Info

Sep 16, 2004

I have one table that has unique id's associated with each row of information. I want to delete rows of information in one table that have a unique ID that references information in another table.

Here is a basic breakdown of what I am trying to do:

Table1 (the table where the rows need to be deleted from)
Column_x (Holds the id that is unique to the various rows of data - User ID)

Table2 (Holds the user information & has the associated ID)
Column_z (holds the User ID)

I tried this on a test set of tables and could not get it to work. What I am trying to do is skip all rows of Table1 that have ID's present in Table2, and delete the rows of ID's that are not present in Table2.


SELECT Column_z
FROM dbo.Table2
DELETE FROM dbo.Table1
WHERE Column_z <> Column_x

This did not seem to do what I needed, it did not delete any rows at all.

I wanted it to delete all rows in Table1 that did not have a reference to a user ID that matched any ID's in Column_z of Table2

Then I tried another scenerio that I also needed to do:


SELECT Column_z, Column_a
FROM dbo.Table2
DELETE FROM dbo.Table1
WHERE Column_z = Column_x AND Column_a='0'

'0' being the user id is inactive so I wanted to delete rows in Table1 and remove all references to users that were in an inactive status in Table2.

Neither one of the Queries wanted to work for me in the Query Analyzer when I ran them. It just said (0) rows affected.

Any ideas on what I am doing wrong here?

Self-referencing Table

Sep 1, 2007


I'm using MS SQL 2005 Express.

folderName varchar(50) NOT NULL,
parentFolderID int NULL

if I add an ON DELETE CASCADE to the foreign key, then i get an error... which is annoying. If a folder is deleted, then all its sub-folders should also be automatically deleted.

The error is: 'Introducing FOREIGN KEY constraint 'FK__Folder__parentFo__7D78A4E7' on table 'Folder' may cause cycles or multiple cascade paths. Specify ON DELETE NO ACTION or ON UPDATE NO ACTION, or modify other FOREIGN KEY constraints.'

Anyone got any advice?

Using Employee/Boss Self Referencing Table

Feb 28, 2008

I have an Employee table that has
EmployeeID (PK)
SupervisorID (which is really just another EmployeeID)
..random junk...

Now that part makes sense, everyone gets one and only one boss.

Their boss can change, and therefore the SupervisorID would be updated.

Now I have an EmployeeEvals table that has quarterly evaluation data.

I want to relate these two tables.

Eval table has
EvalID (PK)
ReviewedEmployeeID (the one being evaluated)
SupervisorID (the one doing the evaluation)

Now I need to link this back to the employee table (at least I think I do).

So I would want to relate it by the ReviewedEmployeeID going back to EmployeeID in the employee table and I also want the SupervisorID to do the same...

But of course that won't work because that would seem to indicate that a single record on the Employees table (say EmployeeID 55) should have a matching (or could) record in the Eval table that would look like
EvalID: 12345
ReviewedEmployeeID: 55
SupervisorID: 55

which of course wouldn't happen as an employee wouldn't evaluate themself.

How do I handle the relationships for this properly?

Do I just not link the SupervisorID back to anything?

Instead Of Update Trigger W/ Self-Referencing Table

May 1, 2006

Using SQL 2005


ID Name RefID
1 Test1 <NULL>
2 Test1a 1
3 Test1b 1
4 Test1b1 3
5 Test1b1a 4



SET ID = @new_ID
WHERE ID = @old_ID

SET RefID = @new_ID
WHERE RefID = @old_ID


RefID is the FK to ID
ID is also the PK to another table and has the relationship use cascading Delete and Update.

"The UPDATE statement conflicted with the SAME TABLE REFERENCE constraint"
This is referring to the first UPDATE of the Trigger.
It was my understanding that Instead Of checks the constraints after it is all done yet it errs with the first Trigger UPDATE.
I was expecting to overcome the self-reference constraint issue by using Instead Of and with the first Trigger UPDATE, change the ID(PK) and then change the RefID(FK) with the second Trigger UPDATE.
Once that was done, it should have not had any constraint problems. Thoughts?

Thanks, Nathan

T-SQL (SS2K8) :: Inserting Into A Self-referencing Table Using Identity Int

Jul 14, 2014

We are in the conversion process of making the database ints.This is a change from a guid PK to an integer based PK that uses an int Identity. The program still uses the guid, and we are trying to map that guid to the databases int.We insert using TVPs passed from code. Since the identity is being set upon insert I have three things to accomplish:

1) Insert all the data into the dbo table
2) Update the parent Id in the table
3) Pass the SetsId guid, Sets_Id int, ParentSets_Id int back to the program

This is a high transaction table that will have a lot of records (millions).

--Sample table creation. There is a FK between Sets_Id to ParentSets_Id, Clustered PK on the Sets_Id
IF NOT EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[dbo].[JSets]') AND type in (N'U'))

I know that it is possible for one column to reference two different parent tables by defining two foreign keys on a same column, I have done it and SQL Server does give any error. But I want to know that is it advisable to define multiple foreign key on a column referncing two differnt parent table's primary key in differnt case... ? Means If Case 1 then It should reference to column1 or table1 otherwise it should reference to table2? How is it practicle...?

SQL Server 2012 :: Building Self-referencing Hierarchical Table

May 21, 2014

An example of what I am talking about is the employee table in the Adventureworks database. This has employeeID and then ManagerID, ManagerID just being the EmployeeID of the person whom the original reports to.

I know the queries for querying this type of data and even making recursive common table expressions. What I cannot seem to find is how one goes about BUILDING said table. I see all sorts of examples where people are just doing INSERT table VALUES () manually to load the table. The problem is, I need to create a table that has potentially thousands of records.

It will essentially be a dimensional map. Don't even get me started as to they why, I will just suffice to say that is what the client and project want . I have a process that will do this now, but it is not very dynamic and very hard coded. To me, there seems like there should be some sort of standardized methodology for handling this.

Problem Referencing A Column In A Table Variable In A Query.

Apr 23, 2006

Hello All

I have the following problem running an sp with a table variable (sql server 2000) - the error which occurs at the end of the query is: "must declare the variable @THeader" . @THeader is the name of the variable table and the error occurs with such references as @THeader.ApplyAmt, @THeader.TransactionHeaderID, etc.

declare @THeader TABLE (
TransactionHeaderID [int] NOT NULL ,
PatientID [int] NOT NULL ,
TransactionAllocationAmount [money] NOT NULL ,
ApplyAmt [money] NULL ) - create table variable

insert into @THeader select TransactionHeaderID,PatientID,TransactionAllocationAmount,ApplyAmt from mtblTransactionHeader where PatientID = 9 - fill the table variable

set TransactionAllocationAmount =
(SELECT isnull(Sum(mtblTransactionAllocation.Amount),0)
FROM mtblTransactionAllocation where mtblTransactionAllocation.DRID = TransactionHeaderID or
mtblTransactionAllocation.CRID = TransactionHeaderID) from @THeader, mtblTransactionAllocation - do the updates on the table variable

Update @THeader
set ApplyAmt = (SELECT mtblTransactionAllocation.Amount
FROM mtblTransactionAllocation where mtblTransactionAllocation.DRID = TransactionHeaderID and
mtblTransactionAllocation.CRID = 187 and PatientID = 9) from @THeader, mtblTransactionAllocation - do the updates on the table variable

- below is where the problems occur. It occurs with statements referencing columns in the table variable, i.e. @THeader.ApplyAmt

UPDATE mtblTransactionHeader
SET mtblTransactionHeader.TransactionAllocationAmount = @THeader.TransactionAllocationAmount,
mtblTransactionHeader.ApplyAmt = @THeader.ApplyAmt
FROM @THeader, mtblTransactionHeader
WHERE @THeader.TransactionHeaderID = mtblTransactionHeader.TransactionHeaderID - put the values back into original table

Thanks in advance

Instances And History In One Table

Jan 11, 2008

I have a database design question. There're lots of ways to rome they say, and I want to hear what you think of this way.

Government supplies wheel chairs (and thinks alike) to people who need them. They stay in possesion of the (local) government and are distrubuted by a company X.

So we have Tools (Wheelchairs) and Users (of wheel chairs). The life-cycle of a wheel chair is that more than one user while use it over time.

I want to keep track of which users used a instance of a wheelchair.

No there's a developer who likes to put this in one table. (the chair and it's user) in a way like this

UID, WheelChairId, UserId, OwnerId, SerialNumber, BeginDateTime, EndDateTime, SomeOtherColumns

The UID is unique, the WheelChairId is a GUID which is Unique per wheelchair, but can have mutliple records in the table with no overlap.

If one of the values of the columns is changed a new record is made with the same wheelchair and a new begin date (the closed record gets an Enddate). So history is made automaticaly. By using the right query's I can see what users uses the chair in what period of time. But also changed ownerships and other changes in Someother columns overtime.

Is this a good or a common practice? Why use it, or stay away from it?

Common Need: History Table

Jan 22, 2008

Hi there!

I'm working on an application designed like this:
There's a table "DailyTransations" (DT) containing daily transactions...
Then there's an archive table "TransationsArchive" (TA) with the exact same structure.

When a record is inserted in DT, it is also in TA (via a trigger) and the reporting is done against TA.
Now for performance issues, we delete from DT the records older than 2 days since they are not needed for processing.

First, what do you think of that implementation?

We thought about using partitions based on the transaction date and completely eliminate TA, but it seems once a record is assigned to a partition, it is not moved automatically...

What is the common solution for this need?

Visual Studio Closes When Accessing The Columns Tab Of A Lookup Transformation Referencing SQL 7 Table

Jul 30, 2007

I'm creating a new Integration Services Project that copies data out of a SQL 7 server, transforms it, and places the data on a SQL 2005 (SP 2) Server. When defining a lookup transformation, if I specify an OLE DB Connection to my server running SQL 7 as the reference table, as soon as I click on the Colums tab, Visual Studio closes / crashes and dumps me to windows. I don't get an error message. If however I specify a connection to a server running SQL 8, or SQL 2005, no problems.

Is this supposed to happen?

My workstation is running Windows XP Pro SP2, Visual Studio 2005 Pro.

Version 9.00.1399.00

The server that doesn't work for a reference table is running Windows 2000 Server SP4

How To Design The History Table To Be More Efficient?

Feb 8, 2007

I am running a website of crossword puzzle and Sudoku games. The website is designed to be:
There are 20-30 games onlines each day.
Every registered user could play and submit the game to win scores.
For each game, every registered user could get the score for ONLY one time. i.e., No score will be calculated if the user had finished the game before.
To avoid wasting time on a game finished before, user will be notified with hint message in the page when enter a already finished game.

The current solution is:
3 tables are designed for the functions mentioned above.
Table A: UserTable --storing usering information, userid
Table B: GameList --storing all the game information.
Related fields:
GameID primary key
FinshiedTimes recording how many times the game has been finished
Table C: FinishHistory --storing who and when finished the game
Related fields:
GameID ID of the game
UserID ID of the user
FinishedDate the time when the game was finshied

PS: Fields listed above are only related ones, not the complete structure.

Each time when user enters the game, the program will read Table B(GameList), listing all the available game and the times games have been finished. User could then choose a desired game to play.

When user clicks the link and enter a page showing the detail content of the game, the program will read Table C(FinishHistory) to check whether user has finished this game before. If yes, hint message will be shown in the page.

When user finishes the game and submit, the program will again read Table C(FinishHistory) to check whether user has finished this game before. If yes, hint message will be shown in the page. If no, user will get the score.

Existing Problems:
With the increase of game and users, the capacity of Table C(FinishHistory) grows rapidly. And each time when a game is loaded, the Table C will be loaded to check, and when a game is submitted, the Table C will be loaded to check again. So it is only a time question to find out Table C to become a bottleneck.

Does any one here have any good suggestions to change / re-invent a new structure or design to avoid this bottleneck?

History Table &> X Days Between Progression

May 21, 2008

I work for a college and have recently been working on our enquiries and applications process (getting it onto our big enrollment db rather than standalone). It has all been going well but now they have asked for a report of students where it has taken more than x days or weeks to progress to the next stage code.

For stage codes they basically follow something like application, guidance interview, programme area interview, conditional/ unconditional offer... Although they could skip a stage code.

Any ideas how to do this bearing in mind I can't guarantee them to go to every stage so really I need to look in the history table and find records more than x days apart where one is the next progression date of the other. Hope I explained that ok.

history table is similar to:

New Unique Number In History Table

May 23, 2008

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

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!

- when user change password it's need to be uniqe and it should not appear last 10 passwords
- Each user can have a maximum of 10 lines containing history password table
- Most old password deleted and replaced with a new password will enter the correct date (FIFO method first in first out).
