What Relationship To Use Between These Two Table?
Hi I have two tables:
1.) Operator
-OperatorID{PK, int, not null}
-OperatorName{varchar(100), not null}
-Enabled{bit, not null}
-PasswordChange{bit, not null}
-BirthDate{datetime, not null}
2.) Password
-PasswordID{PK, int, not null}
-Password{varchar(50), not null}
-ExpirationDate{datetime, not null}
I'm not sure how to design and layout these two tables. The layout of these two tables is completely flexible as the application has not been deployed. I'm open to any good suggestions.
For each Operator I want to stored up to 3 previous passwords plus their current password. The password change field is so that if the operator's password expires or gets reset, they will be forced to enter a new password. This is a simple internal company application, so password encrypting is not necessary. The ExpirationDate indicates the date that the password will expire.
Hope to hear from someone soon! Thank you!

How Can I Create A One-to-one Relationship In A SQL Server Management Studio Express Relationship Diagram?
How can I create a one-to-one relationship in a SQL Server Management Studio Express Relationship diagram? For example: I have 2 tables, tbl1 and tbl2. tbl1 has the following columns: id {uniqueidentifier} as PK name {nvarchar(50)} tbl2 has the following columns: id {uniqueidentifier} as PK name {nvarchar(50)} tbl1_id {uniqueidentifier} as FK linked to tbl1.id If I drag and drop the tbl1.id column to tbl2 I end up with a one-to-many relationship. How do I create a one-to-one relationship instead? mradlmaier

Table Relationship
Hello, I created some SQL 2005 tables using Microsoft SQL Server Management Studio. I need to get the script code of those tables. I was able to do that by right clicking over each table. But how can I get the code for the relationships between the tables? Can't I create relationships between two tables by using T-SQL? Thanks, Miguel

Relationship Inside The Same Table
i ve got a database that has a table...that table has a relationship between its primary key,and another field,actuelly i did it for doing menus and sub menus,so each menu has an ID say menuID and it has DEPTH and parentID which is the menuID of the parent...the problem is that i can not use "Cascade update Related Fields" or "Cascade Delete Related Records" which are really necessary ...for example when deleting parent ,not to have a child lost :)i hope i ll have an answer soon,and thanks in advancedPS: i am using MSSQL 2000 evaluation

Combine Relationship Table
Hello everyone: I have two database desgin questions. I hope could get some helps here to resolve my puzzle. suppose I have a parent table which has many-to-many relationship to its three children tables. E.g: Parent table: webpage -pageID -pageTitle child table: (which are the content could be in the webpage) Picture ---pictureID ---pctureName StreamVideo --videoID --videoName StreamAudio --audioID --audioName Normally, in a many-to-many relationship, a third table will be introduce to break down the many-to-many into one-to-many relationship. So in this case, I will have three relationship tables 1. Webpage--Picture --pageID --pictureID 2. Webpage--Video --pageID --videoID 3. Webpage--Audio --pageID --audioID My question is should I combine this three relationship table into one big relationship table like: Webpage--content --pageID --pictureID --videoID --audioID I know the drawback of this combining will cause redundant, but this could avoid join tables when writting query (especially when there are more child table associate with one parent table). Also I was told that foreign key can be nullable, so if one webpage only have pictures, as long as I insert pictureIDs with the null value videoIDs and audioIDs into the Webpage--content table, then it seems I don't duplicate anything. So far I don't see anything wrong with this approach, I hope someone can give me some suggestions whether I should go this way. My another question is also about the relationship table, suppose in the above exmaple, we won't combine those three relationship tables. But we need to assign a value to each pictureID, videoID, audioID. And this value will be different if a pictureID, videoID, aduioID appears in different webpage. How I should solve this issue? The best I can think so far is add a value column in the relationship table. But I have not seen people did this before. Add columns into a relationship table. Is this a good desgin?

Table Relationship In VB Express
I have 3 tables I am trying to relate for a music player. I was following the example in the msdn however, my relationships do not seem right. Here are tables i want to relate: Table 1: ArtistID ArtistName: Table 2: RecordingID RecordingName ArtistID Table 3: TrackID TrackName TrackNumber TrackLocation RecordingID So the main idea here is that the foreign keys are recordingId and artistID. So what i did is created the 3 tables and then make a diagram to create the relationships. I then was reading this post: http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=219696&SiteID=1 What i want to do is use 2 different text boxes lets say and as i move from the records in the Record_table (2) the corresponding artist will change with it. However in the dataset the relationship looks like this: Artist -> Recording -> Track.... inorder for me to get this relationship to work correctly i have to change all the relationships in the dataset diagram. This way the dataset would look like this: Track -> Recording ->Artist. This way i can use the 2 bindings to reference each other as stated in the link above. why doesnt the relationship of the database know this already? why do i have to change the relationship in the datasets.

Table Relationship. What Am I Doing Wrong?
Hello, I have 3 tables: Articles, ArticlesTags and Tags. ArticleTags relate Articles and Tags records. When I try to delete a record in Tags I get the following error: The DELETE statement conflicted with the REFERENCE constraint "FK_ArticlesTags_Tags". The conflict occurred in database "MyDB", table "dbo.ArticlesTags", column 'TagID'. The statement has been terminated. What am I doing wrong? Here is how I am creating my tables: create table dbo.Articles ( ArticleID uniqueidentifier not null constraint PK_Article primary key clustered, Body nvarchar(max) not null ) create table dbo.ArticlesTags ( ArticleID uniqueidentifier not null, TagID uniqueidentifier not null, constraint PK_ArticlesTags primary key clustered (ArticleID, TagID), constraint FK_ArticlesTags_Articles foreign key(ArticleID) references dbo.Articles(ArticleID) on delete cascade, constraint FK_ArticlesTags_Tags foreign key(TagID) references dbo.Tags(TagID) ) create table dbo.Tags ( TagID uniqueidentifier not null constraint PK_Tag primary key clustered, [Name] nvarchar(200) not null ) Basically, what I need is: 1. If an Article is deleted then: > Delete all records for that Article in ArticlesTags > Don't delete any Tag in Tags. 2. If an Tag is deleted then: > Delete all records associated with it in ArticlesTags. > Don't delete any Article in Articles. What am I missing? Thanks, Miguel

Create Table With Recursive Relationship
I am fairly new to SQL and I am currently trying to createa SQL table (using Microsoft SQL) that has a recursiverelationship, let me try to explain:I have a piece of Data let's call it "Item" wich may again contain onemore "Items". Now how would I design a set of SQL Tables that arecapable of storing this information?I tried the following two approaches:1.) create a Table "Item" with Column "ItemID" as primary key, somecolums for the Data an Item can store and a Column "ParentItemID". Iset a foreign key for ParentItemID wich links to the primarykey"ItemID" of the same table.2.) create separate Table "Item_ParentItem" that storesItemID-ParentItemID-pairs. Each column has a foreign key linked toprimary key of the "Item" Column "ItemID".In both approaches when I try to delete an Item I get an Exceptionsaying that the DELETE command could not be executed because itviolates a COLUMN REFERENCE constraint. The goal behind these FK_PKrelations is is that when an Item gets deleted, all childItems shouldautomatically be deleted recursively.How is this "standard-problem" usually solved in sql? Or do I inned toimplement the recursive deletion myself using storedprocedures or something ?

Search On Table With Recursive Relationship
I am using tables with recursive relationships extensively. For example the table tbComponent has a primary key called Co_ID and a foreign key called Co_Co_ID which references the field Co_ID. This allows a component to have unlimited child components, and each child component can have an unlimited number of tiers of children. I have a few question for which I have seen no documentation on. 1. How can I create a view or a SP that will return a component record and all of its children and children's children records down to the last/lowest child record? 2. I need to be able to do a search in this table. Example: Table: tbComponent Columns: Co_ID Integer Co_Co_ID Integer Co_Name Text Co_Attribute Text Co_Category Text Note: the data for Co_Category comes from a lookup table with also has a recursive relationship to itself where a category can have an unlimited number of tiers of children categories. A typical group of records could be something like this: Co_ID Co_Co_ID Co_Name Co_Attribute Co_Category 1 1 Car Blue Ford 2 1 Body Steel Parts 3 2 Door Front Parts 4 3 Invoice April 1 1999 Accounting Ok, say there is over a million records in this table. Say I want to query this table and return all of the invoices for cars between March 1 1999 and May 1 1999. Say for example that there are less records where Co_Name has a value of Car then there are records with a value of Invoice, so logically I would set some kind of criteria to limit only invoices with where Co_Name = "Car". That's easy, I can return a result set of all the records Where Co_Name = "Car" and I can hold these in a view or a temp table. Now I need to query this View or temp table and see if it has any children records records Where Co_Name = "Invoice" . The problem is that the Invoice child could be a child record directly under the "Car" record, or 10 levels of children records down. The logic for this would be: If Co_Name = "Car" Then Select * Where Co_Co_ID = 1, then take all of those record's values in Co_ID and run another statement Where Co_Co_ID = X and so on until there are no more children to search. If any of those records have a value of Invoice in Co_Name then return them. Please don't give any speeches on Normal Relationship Database design suggesting a typical design using something like a Car table, a parts table, and a invoice table. I used the example above to demonstrate the dynamics of doing a search on a recursive relationship. I understand relationship theory and a recursive relationship is what we need to use in our situation. Thanks for any and all input!

Link Table Versus XML Column For One-to-many Relationship
I am designing a database schema where several tables have one-to-many relationships to records in other tables. One way to implement it is to create a link table for each pair of tables that have a relationship: identity Table1_ID Table2_ID 1 12 9 2 12 15 3 18 42With the SQL 2005 support for the XML data type, there is the possibility of storing the IDs in an XML column. The XML stored with a record (equivalent to record 12 from the above example) might look like this: <Links> <Table2_LinkType> <ID>9</ID> <ID>15</ID> </Table2_LinkType> <Table8_LinkType> . . . </Table8_LinkType> </Links>The XML column method has the advantage of not requiring that a separate table be created but does not enforce referential integrity. The link table method has the advantage of allowing constraints to enforce referential integrity but has the disadvantage of requiring the creation of a separate table for each pair of tables having a relationship and joining to an additional table has performance implications. Implementing standard Add, List and Delete operations for the link table method is straightforward. As a test and to familiarize myself with the new XML features, I created Set, List and Delete stored procedures for the XML method. Both methods will work. In deciding which method to go with are there any other issues I should be considering besides database integrity, complexity and possible performance issues? From the standpoint of best practices and coding standards is one method preferred over the other? Here is some additional information. The data set I will be working with has table sizes numbering in the hundreds of thousands. Any given record will only be linked to at most a half-dozen records in any other table. I searched on-line for information and I was able to find plenty of good articles discussing how to use the new XML data type in SQL. However, I was not able to find any information on when not to use the XML data type over equivalent joined-table methods.

Insert Statement For Junction Table On Many To Many Relationship Ms Sql Server 2005
Hello, This seems like such a simple problem but I am new developer even through I have been on the administration end of things for some time. I will go into more detail about my tables and there relationships below. Anyway, I am trying to create a many-to-many relationship within ms sql server 2005. I have created both of my primary tables and also a junction table per the directions on microsoft's website all per ms's instructions as stated here... http://msdn2.microsoft.com/en-us/library/ms178043.aspx At then end of these instruction it states as a NOTE: The creation of a junction table in a database diagram does not insert data from the related tables into the junction table. For information about inserting data into a table, see How to: Create Insert Results Queries (Visual Database Tools). http://msdn2.microsoft.com/en-us/library/ms189098.aspx and these directions do not go into detail on how to do an insert on a junction table. And I cant find out how to do this anywhere on the internet... I did create a T-SQL INSERT statement in a trigger as listed below but I end up getting an error AS LISTED BELOW.... Here is how I set everything up... PetitionSet table consists of: PetitionSetID int auto-increment primary key PetitionSetName varchar(50) no nulls PetitionSetScope varchar(50) no nulls the Petition table consists of: PetitionID int auto-increment primary key PetitionSetID int no nulls PetitionName varchar(50) no nulls the SetToPetitionJunction table consists of: PetitionSetID int PetitionID int And, there is a composite key made up of both the PetitionSetID and PetitionID fields. I have created the foreign key relationships with DEFAULT VALUES from the SetToPetitionJunction table to each column's respective corresponding column in each of the tables: PetitionSet and Petition. The trigger is on the Petition table and it has the following code: set ANSI_NULLS ON set QUOTED_IDENTIFIER ON go -- ============================================= -- Author: Name -- Create date: -- Description: -- ============================================= ALTER TRIGGER .[SetToPetitionJunctionTrigger] ON .[dbo].[Petition] AFTER INSERT AS BEGIN -- SET NOCOUNT ON added to prevent extra result sets from -- interfering with SELECT statements. SET NOCOUNT ON; INSERT INTO SetToPetitionJunction (PetitionID, PetitionSetID) SELECT Petition.PetitionID, PetitionSet.PetitionSetID FROM Petition INNER JOIN PetitionSet ON Petition.PetitionSetID = PetitionSet.PetitionSetID END I have created an asp.net 2.0 front end to insert values into the PetitionSet table and the Petition Table. And in the detailsview for the Petition table I manually insert the PetitionSetID field to the number that corresponds to an auto-generated number on the primary key of the PetitionSet table. So I am maintaining referential integrity... The first time it works and inserts one record in the Junction table containing the PetitionSetID from the PetitionSet table and the PetitionID from the petition table. Then when I try to add in another petition for the same petition set number just like I did the first time and then I get this error... Violation of PRIMARY KEY constraint 'PK_SetToPetitionJunction'. Cannot insert duplicate key in object 'dbo.SetToPetitionJunction'. The statement has been terminated. David All Rights Reserved in All Media

Failing To Create Relationship (SQL Server Claims Table Lacks PK For Some Reason ?)
I tried to create a relationship in EM's diagram pane inSQL Server 2000 (I'd list the version of EM, but About gives methe MMC version, which is probably not relevant.)(The database itself is SQL Server 2000 SP3.)I got an error that I don't understand (because, at leastat first blush, it appears to be quite untrue). Note thatI have never clicked before on the diagrams child of thedatabase; this was entirely experimental."Primary key or UNIQUE constraint must be defined fortable 'xxx' before it can participate in a relationship."http://msdn.microsoft.com/library/d...cantbepktbl.asp1) My table already had a primary key; why is MS SQL Server apparentlyclaiming otherwise ? (I don't think I can define a second primary keyon the same table. I could perhaps define an additional unique indexon top of the primary key, but, I'm not sure.)2) What does it mean: table '<0s>' ? That is, what does 0s mean ?

One-One Relationship
Hi,Do you guys know what's wrong with a one-to-one relationship?The reason I want to make it like this is that at the very end of the chain,the set of keys is huge. I want to limit the number of columns to be thekey. i.e. the [company] table has 1 column as the key. The [employee]table will have 2 columns as the key.e,g,If I add a [sale] table to the [company]-[employee] relationship, the thirdtablewill have 3 columns as the key -- "company id", "employee id", and "saleid".(e.g.)I have a company with many employees and computers. But instead of classifyall these, I just want to call all these as an entity. A company is anentity. An employee is just another entity. etc.So, instead of a one-to-many:[company]---*[employee]---*[sale]||*[computer]I make it one-to-one.[entity]---*[entity]If I want to know the name and address of the entity "employee", I will havea 1-to-1 table [employee] to look up the information for this employeeentity.[entity]---*[entity]||[company]||[employee]||[computer]||[sale]--[color=blue]> There is no answer.> There has not been an answer.> There will not be an answer.> That IS the answer!> And I am screwed.> Deadline was due yesterday.>> There is no point to life.> THAT IS THE POINT.> And we are screwed.> We will run out of oil soon.[/color]

Introducing FOREIGN KEY constraint 'FK_tblClient_tblActivedir1' on table 'tblClient' may cause cycles or multiple cascade paths. Specify ON DELETE NO ACTION or ON UPDATE NO ACTION, or modify other FOREIGN KEY constraints. Could not create constraint. See previous errors." What i have is 2 tables. 1 named client 1 named activedir In the client table the columns i want to bind with activedirtable are FR1 and DC1 I want to bind them in the ID of the activedir table (both, in different fk relationships) so that they get the id of activedir. Fr1 has an fk relationship with activedir (pk is activedir' id) and DC1 exactly the same in another fk. So i want both columns to comunicate with activedir. If p.e. activedir has 3 elements (a,b,c) when i delete element a then werever FR1 or DC1 have this element(binded to it's id) then the element will also be deleted (id of the element) from both FR1 and DC1 I don't want to set Delete and Update action to none because i want the element changed or deleted from activedir, to do the same on Fr1 or DC1 or both. Any help? Thanks.

ERD 1:1 Relationship

In table 2 I have an int as the primary key and a column that takes the uniqueidentifier from table 1. Everytime I drag and drop the relationship line and link table 1 to table 2 it creates a 1:N relationship: ie. tbl1.primarykey links to tbl2.column2. So I'm not linking primary key to primary key however I still want a 1:1 relationship. How do I do that? Thanks in advance.

One To One Relationship
How do I create a one to one relationship in a SQL2005 Express database? The foreign key needs to be the same as the primary key so it can't just increment to the next number.
