Trying To Enforce Ref Integrity On Hierarchy Table Relationship
Dec 28, 2007
I've got a table that includes:CREATE TABLE [dbo].[Content] (
[Id] int IDENTITY(1, 1) NOT NULL,
[ParentId] int NULL,
I'm wanting to make sure that a ParentId must be in the table as Id someplace else. When I try to do it by making it a foreign key get the error:
--------------- SQL ---------------
ALTER TABLE [dbo].[Content]
ADD CONSTRAINT [Content_fk3] FOREIGN KEY ([Id])
REFERENCES [dbo].[Content] ([ParentId])
ON UPDATE NO ACTION
ON DELETE NO ACTION
GO
---------- ERROR MESSAGE ----------
There are no primary or candidate keys in the referenced table 'dbo.Content' that match the referencing column list in the foreign key 'Content_fk3'.
Could not create constraint. See previous errors.
Any ideas?
ALTER TABLE [dbo].[Content]
ADD CONSTRAINT [Content_fk3] FOREIGN KEY ([Id])
REFERENCES [Content].[dbo] ([ParentId])

Hi,I have two tables Table A and B, below with some dummy data...Table A (contains specific unique settings that can be requested)Id, SettingName1, weight2, lengthTable B (contains the setting values, here 3 values relate to weightand 1 to length)Id, Brand, SettingValue1, A, 1001, B, 2001, null, 3002, null, 5.3(There is also a list of Brands available in another table). No primarykeys / referential integrity has been setup yet.Basically depending upon the Brand requested a different setting valuewill be present. If a particular brand is not present (signified by anull in the Brand column in table B), then a default value will beused.Therefore if I request the weight and pass through a Brand of A, I willget 100If I request the weight but do not pass through a brand (i.e. null) Iwill get 300.My question is, what kind of integrity can I apply to avoid the userspecifying duplicate Ids and Brands in table B. I cannot apply acomposite key on these two fields as a null is present. Table B willprobably contain about 50 rows and probably 10 of them will be brandspecific. The reason its done like this is in the calling client code Iwant to call some function e.g.getsetting(weight) .... result = 300Or if it is brand specificgetsetting(weight,A) ..... result = 100Any advice on integrity or table restructuring would be greatlyappreciated. Its sql 2000 sp3.Thanksbrad
Hi I have a problem. I have a replicated database. Now I have a couple of tables within the database where I delete the content row by row and caluted the new record and insert them. Now when I do this on the development system that is unreplicate it is fine. However on production that is replicated I get this error:
System.Web.HttpUnhandledException: Exception of type System.Web.HttpUnhandledException was thrown. ---> System.Data.SqlClient.SqlException: INSERT statement conflicted with COLUMN FOREIGN KEY constraint 'FK_VARLISTS_USERVARLISTS'. The conflict occurred in database 'BHP', table 'USERVARLISTS', column 'AutoID'. INSERT statement conflicted with COLUMN FOREIGN KEY constraint 'FK_VARLISTS_USERVARLISTS'. The conflict occurred in database 'BHP', table 'USERVARLISTS', column 'AutoID'. INSERT statement conflicted with COLUMN FOREIGN KEY constraint 'FK_VARLISTS_USERVARLISTS'. The conflict occurred in database 'BHP', table 'USERVARLISTS', column 'AutoID'.
Now I persume this is caused by the foreign key being contrained by the replicated database. I had though about unticking the box 'Enforce Relationship for replication' but I am not sure what problems this may cause.
Woudl this fix my problem? If not do you have any idea what would.
I am working on a model where I have a sales fact table. Each fact record has four different customer fields (ship- to, sold-to, payer, and bill-to customer). I have one customer dimension table that joins to the sales fact table four times (once for each of the customer fields above). When viewing the data in Excel, I would like to have four hierarchies (ship -to, sold-to, payer, and bill-to customer) within Customer.
Is there a way to build hierarchies within my Customer dimension based on the same Customer table? What I want is to view the data in Excel and see the Customer dimension. Within Customer, I want four hierarchies.
I am trying to create a new mining structure with case table and nested table, the case table (fact table) has alread defined the relationships with the nested table(dimension table), and I can see their relationship from the data source view. But why the wizard for creating the new mining structure showed that message? Why is that? And what could I try to fix it?
Hope it is clear for your help.
Thanks a lot for your kind advices and I am looking forward to hearing from you shortly.
I have a table named 'DepartmentItem' which is designed with hierarchy structure. The column 'ParentId' from table DepartmentItem indicates parent-child relationship and department root among records. I have written and run a user-defined function I use recursive approach, but the function runs slowly.
My question: is there a better way to query that hierarchy table instead of using recursive?
** The current user-defined function that is written using recursive:
CREATE FUNCTION dbo.fnGetDepartmentTree ( @departmentItemId int ) RETURNS TABLE AS RETURN with DepartmentItemTree(DepartmentItemId , DepartmentItemTypeId , ParentId, ItemOrder, Level)
[code].....
** And definition of table 'DepartmentItem' :
DepartmentItemId int IDENTITY(1,1) NOT NULL, ParentId int NULL, -- Each department root starts when this column is NULL or the current row is department root. If it is not NULL then the current row has ParentId whose record has DepartmentItemId = ParentId of the current row (see more below) IsActive bit NOT NULL DEFAULT ((1)),
I have a table "t_prod_cat" which contains hierarchical data which is used in production to present data.
CREATE TABLE [dbo].[t_prod_cat]( [cat_node_id] [bigint] IDENTITY(1,1) NOT NULL, [advertiser_id] [bigint] NOT NULL, [cat_hid] [hierarchyid] NULL, [level] AS ([cat_hid].[GetLevel]()) PERSISTED, CONSTRAINT [PK_t_prod_cat] PRIMARY KEY CLUSTERED ( [cat_node_id] ASC )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] ) ON [PRIMARY]
In order not to impact the production website during the time an advertiser is editing (the editing might take much time and also mainly because at any time during the editing, the advertiser could cancel all the changes he did), I was thinking of transferring all the data linked to that advertiser to another table and let the advertiser apply any modifications up to the moment he will commit the changes.
Therefore, I would like to "CLONE" the hierarchy related to a certain advertiser_id to another table "t_prod_cat_work"
CREATE TABLE [dbo].[t_prod_cat_work]( [temp_cat_node_id] [bigint] NOT NULL, [temp_cat_hid] [hierarchyid] NOT NULL, [advertiser_id] [bigint] NOT NULL ) ON [PRIMARY]
What can be the easiest way to clone all the hierarchical data (multi-levels) from 't_prod_cat' to 't_prod_cat_work' for a certain advertiser_id ?
I like to get data from a signle table and arranged in hierarchical(hierarchy) order. What will be my sql script to be able to get the desired result shown below? Please include some explanation as too what script is doing..

I have transaction table where the rows entered into the transactioncan come a result of changes that take place if four different tables.So the situation is as follows:Transaction Table-TranId-Calc AmountTable 1 (the amount is inserted into the transaction table)- Tb1Id- Tb1AmtTable 2 (an amount is calculated based on the percentage and insertedinto the transaction table)-Tbl2Id-Tb2PercentageTable 3 (the amount is inserted into the transaction table)-Tbl3Id-Tbl3AmutTable 4 (an amount is calculated based on the percentage and insertedinto the transaction table. )-Tbl2Id-Tb2PercentageHow do I create referential integrity between the Transaction table andthe rest of the tables. When I make changes to the values in Table 1 -4, I need to be able to reflect this in the Transaction table.Thanks.
However, the userelationship function does not override the active relationship between Operation & Advice and so the measure is limited to Advices directly filtered by the Operation table.
If I delete the relationship between Operation and Advice, then the measure works as expected i.e. Operation indirectly filters Operation Commodity which filters Advice.
insert into Hier select 'subramanium','Manickam' union all select 'subramanium','Munuswamy' union all select 'Munuswamy','senthil' union all select 'Munuswamy','sasi' union all select 'Munuswamy','uma' union all select 'manickam','vijay' union all select 'manickam','bhavani' union all select 'manickam','dhanam' union all select 'uma','varsha'
Delete from Hier where child='uma'
I tried:
select parent from Hier where parent not in(select Child from Hier) and parent <> 'subramanium' Getting resultset as: parent ====== uma
I need to know whether my select statement is correct or not,if its correct,how to write the same in CTE?
I have one table Emp_MAster with two column ID-Sup_Id. I need to create a table where i can store data link this
Id-Hreid
Only difference is that I need to store data in an hierarchy view so Emp 1 is reporting to Emp2 and Emp2 is reportign to Emp3 so in new table I should get
I have been trying to convert an existing table that used adjacency list model (parentid,childid) to a table that use hierarchy Id type. So early on, I notice my original data does contains multiple roots. So I took a step to create dummy nodes to ensure all nodes fall into a single root structure. Another important fact is that each child node can have multiple parents.
My original source table contains 22461 records, when running the query below step 2 produces explosive number of records around 175,000+ records. I spent hours study the result and couldn't understand what actually causing this, I ran it against small set of test data I didn't seem the issue caused by child with multiple parents.
select * from SourceTable -- produces 22461 records
--step 1: first, get row number of child records in each parent
SELECT ChildID,ParentID, ROW_NUMBER() OVER (PARTITION BY PARENTID ORDER BY PARENTID) as Num INTO #RelationshipTmp FROM SourceTable;
I'm attempting to load some data into an explicit hierarchy in MDS 2012 via the staging table and struggling with the HierarchyName field. Specifically I'm loading data into stg.[Entity Name]_Consolidated and using the exact name of the explicit hierarchy I've set up in the front end web application.
Originally my hierarchy was labelled "Reporting Hierarchy" and when loading the data into staging using this name then running the batch from the Import Data screen I can see the error message "Error - The HierarchyName is missing or is not valid.". I've checked the table mdm.tblHierarchy and can see that the name there is exactly as it was in the staging table and have since renamed the hierarchy as "Reporting_Hierarchy" with the same results.
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
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.
Why is it not possible to define more than one relationship per table?
i have a primary table that i would like to cascade deletes to 2 other foreign tables in 2 separate relationships. why can't i do this and what are my alternatives?
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
We have two tables. Users and Projects and there is a many-to-many relationship.Ex. A user can be assigned into multiple projects.For the relationship table, should the table name be UserProjects or ProjectUsers?Also should it be singular or plural? (ex. UsersProjects or ProjectsUsers)?
Hi, I come back again. Can anyone help me to create table with many-to-many relationship. Here is my three tables tbl_Networks ( NID int identity(1,1) primary key, NetworkName nvarchar(256) )
tbl_Categories ( CID int identity(1,1) primary key, CateName nvarchar(256), NID int )
tbl_Sim ( SID int identity(1,1) primary key, NID int, CID int, NameOfSim nvarchar(256) ) My problem is 1 value in tbl_Sim may have multiple values in table tbl_Categories and vice versal. And I don't know how to organise them
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:
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:
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.
I have recently restored an SQL Server 2000 database on SQL Server 2005 A number of constraints on the database had previously been disabled
A monthly process that is carried out, imports data into 'Table A'. This process now crashed, being unable to truncate table as it referenced by 'Table B'
Although when i check the properties of the constraint the 'enforce foreign key constraints' is set to no.
Is there a known issue with restoring databases on 2005,
I have two tables: ads and categories. I have an existing relationship: categories.id (PK) and ads.categoryid (FK). Now I want to create additional relationship with categories.id (PK) on ads.SecondCategoryID (FK). When I try to save it in SQL Manager I get the following error: - Unable to create relationship 'FK_classifieds_Ads_classifieds_Categories2'. The ALTER TABLE statement conflicted with the FOREIGN KEY constraint "FK_classifieds_Ads_classifieds_Categories2". The conflict occurred in database "mydb", table "dbo.classifieds_Categories", column 'Id'.
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.
