Problem When Adding Cascade Actions To A Relationship
Aug 22, 2007
Hello everyone,
I wanted to change a relationship in a database in order for it to have a cascading effect on update and on delete in order to preserve the data integrity. The problem is that when I click the save button I get the following error message:
'Role (Application)' table saved successfully
'Usergroup_Role (Security)' table
- Unable to create relationship 'FK_Usergroup_Role_RoleId_Application_Role_Id'.
Introducing FOREIGN KEY constraint 'FK_Usergroup_Role_RoleId_Application_Role_Id' on table 'Usergroup_Role' 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.
Any suggestion on how can I fix this? For a better understanding of the real problem I've uploaded a picture of the tables diagram. Here's the link

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.
In a previous application i stored about 100.000 actions ( coming from an external system )in an access database for each day. Therefore i created everyday a new accessdatabase to have enough performance. Each month i copied automatically all databases in a new 'month' map as a backup.
The goal of the application is the view all actions of one day of week in one grid. This is a kind of history of the external system.
I'm afraid the application will become to slow if i save all actions in one database. ( after 1 month i will have 3.000.000 actions.
How this is done in an sql server ? Do i have to use a different kind of method ?
Hi! My problem/"goal to achieve" is the following.. Users can insert orders in a db-table. The date on which they've been created is stored. I want the server to insert a new record in another table (accounts) for every order which is older than 2 weeks. How should I do that? With a custom action which checks all orders (a customer must press some button every day). Or a static "update-class" with a kind of timer which does the action every 24 hours? Of course an automatic solution will be the best! Another question is: how can i ensure that an instance of this "update-class" will never die? Thanks so far...
I've recently had a situation where some of the steps in the daily backup job failed. The job is defined such that if a step fails, it goes on to the next step (these are dev. backups :)
Is there a way that I can tell it to notfy me of the step failure AND go on to the next step? The notification is reporting that the job was successful when in fact a couple of the steps failed. Is there any way around this?
I am having a question on cube actions. What is the easiest way for us to see all actions properties(including objects to trigger the actions, etc.), hope it is clear for your help and I am looking forward to hearing from you shortly.
I have to get all the customer records from one table and compare this records with another table and finally if there is same record I have to perform an update but the record does not exist I have to make an insert. How can I do it with SSIS Except writing sql or tsql scripts ?
what are the best ways to action on the Deadlock issues. I am aware how a deadlock is occurred and we can get the queries causing by the Trace, and Profiler. What will en best steps to Investigate from DBA end later collecting the stats.What steps will ensure to get these deadlocks addressed.
Hello,I have several SQL Server jobs that execute procedures written to rundeletes and updates against tables in my data warehouse. Some jobsoccasionally get stuck with the status "Performing Completion Actions"and can only be reset by restarting SQL Server or rebooting theserver.I have seen one answer to this problem in a DTS package is to checkthe box specifying "Close Connection on Completion" for each task. Isthis the equivalent of setting "cursor_close_on_commit" to "on" inT-SQL?? If not, what is the equivalent in T-SQL??Thanks in advance!Cliff
I have an SSAS cube that i want to add some actions to. I've had problems adding a reporting action to the cube so decided just to add a URL action instead. Start simple and build on the concepts...
So i add a new action, give it a name, set the Target Type to Cells, Taget object to All Cells. I've put no condition on the action since i want it to appear all the time.
The action content type is set to URL the action expression is set to [URL] I've also set a caption of "Google" under the additional properties and said that the caption is MDX (I'm aware that it isn't but i do intend to expand on this...).
I then build and deploy my cube, call up excel (2010) and then create a pivot table off the back of the cube but when i right-click the cells in the pivot table and go to "additional actions" it tells me that there are none specified.
I have a cube where i would like to define some actions. I have done report Actions but they are limiting in terms of what i am trying to achieve.I want a popup window from the action from relevant cells at the moment i can use the urlaction type to open the link in a new window which is ok but i want this as a popup.
I have been using database mail for quite a few years now. I started using it with SQL Server 2005 and then it worked fine. Then we went over to SQL 2012 and the problems started. At first I could not get any e-mails out and read a post by Microsoft that a patch needs to come out but not available yet. That was in 2012. Presumably the patch came out with windows updates and my DB Mail started working. Now, however, I have the problem that some e-mails do get sent but the majority failed.
I use this so that whenever a user captures certain data to update a person's status on the database then an automatic e-mail will be sent to that person to inform them of their status at this company.
It seems in the spec that Data Regions can only reference a single dataset, then why bookmarkID and bookmark action can reference a different dataset than the one that the Data Region is using?
Like in this case:
1) create a table with dataset1
2) create another table with dataset2
3) create a bookmarkID using =Last(somefield, "dataset1") in any table cell in the first table
4) create a bookmark action using =Last(somefield, "dataset1") in any table cell in the SECOND table.
This is valid report, and it can preview....
I know this example not practical at all, it is just used to illustrate my question.
Is this a scoping rule exception for any special reasons? or it's just a bug?
If it is a scoping rule exception, please explain, and a practical example would be great.
Does anyone know how to do a cascade update in SQL 2005 using the studio manager?Basically, I have a project table with a status column. If the status is set to 2, then I need to update another table that references the project id.
I have a Sql Server 2005 table with 3 fields, an ID field (primary key), a parent ID field, and Name. The parent ID references the ID field (foreign to primary - many to one) within the same table so that records can reference their parent. I would like to place a cascade delete on the ID field so that when the primary ID is removed it will automatically remove all those records with a parent ID that match. Sql server does not allow me to establish this cascade delete.I was considering a trigger instead but only know how tio use the AFTER paramter and not an alternative. Thanks
We are developing a new oltp application using SQL Server 2000 and are debating whether to use "cascade delets" or not. In earlier apps, we had issues using cascade deletes like someone deleted parent by mistake and all child records got deleted OR SQL Server crashed in middle of cascade delete and records were lost or performance became an issue when there were huge # of child records to be deleted,etc.
Are there any recommendations for/against using Cascade deletes and when to use and when NOT to use cascade deletes ?
Hello all, I am new to SQL and I was hoping someone could explain something to me about 'on update cascade'. I understand what 'on update cascade' does (i think) - it updates the child table when the parent table is updated. What i do not understand is that the 'on update cascade' works on the primary key of the parent table, but i was on the understanding that the primary key doesn't change often if at all so why would the 'on update cascade' be of use? Sorry for my ignorance and i realise i must be missing something simple but would be grateful for any help. Thanks
i just got a job and i have to learn triggers to pass my test , however,i'mfinding the cascade trigger a bit difficult, does it update other tables automatically when a column is updated?
I am a C# programmer also acting as the dba for a SQL Server project. I have a table called Folder that has child records in a table called FolderItems. When a Folder is deleted I want the FolderItems to be deleted. I know how to accomplish via code, but I would prefer to have SQL Server perform the delete just in case a folder is deleted via SQL Management Studio or other method.
Is a trigger the way to go about this? I know how to create triggers For Delete, but I just wondering is this the best method to create a Cascade delete or does SQL have any built in "Cascade" delete features.
Helle people. The question is: I have two tables: Directories and SubDirectories. SubDirectories table has foreign key for DirectoryId. Now if I define this key with ON DELETE CASCADE attribute then in case of I delete a Directory record, all SubDirectory records will also be deleted. But if I have only one table Directories that have field named ParentId and in this field I save an Id of parent direcory. Can I define a parentId field as a foreign key to the same table and define it with ON DELETE CASCADE? Will it work too? Thanks
Hi, I have the following tables: Categories {Category_ID, Column2, ...} Articles { Article_ID, Category_FK, Column3, ...} Discussions {Discussion_ID, Article_FK, Column3, ...} Now, all what I have is just category_ID value (Let us say 3), how can I do cascade delete to delete category's record that its ID = 3 and delete all articles and all discussions that found in that category?
I have a logins table, a loginroles table (intermediate), and a roles table When I delete a login from logins I need to delete the roles for that login from loginroles. I know I have to use cascade deletes, but I cannot find the option in sql 2005. Any help would be appreciated. Thank You,Jason
Is it possible to cascade update and delete while DRI remains there ? That is without deleteing refrential integrity. If anyone have example of cascade delete and Update using Pubs or Northwind Example , i'll be really obliged.
