Foreign Key Constraints problems

1 New Member
I have two simple tables

Employees (primary key table)
Empid, empname,title

MgrXrf (foreign key table)
MgrId,Empid

MgrID & Empid in MgrXrf have a foreign contstrant to EmpID in Employees. That works fine. I don' want to add a record to MgrXRF unless both field values exist in Employees. Problem is I also want to set the delete rule to cascade on both fields, so that if I delete an employee their record is deleted from MgrXRF no matter if they were a manager (mgrID) or an employee (empid). SQL 2005 won't let me do this. When I try to save I get error "introducti ng Foreign key contact FK_MgrXrf_mgrid on table MgrXrf may cause cycles of multiple cascade paths. Specify ON DELETE or ON UPDATE NO ACTION, or modify other foreign constraints." It works fine if I set the DELETE RULE to CASCADE on only one field.

Database 1 is corrupted. Database 2 was created by dba but none of the primary or foreign key constraints were ported over. TOAD won't let me export. I will try ErWin next. What is the best way to recover this information if the views are corrupted and through errors? thanks, Lowly developer

We sometimes get very large databases that we want to cut down to use for testing. The information is all related to a central accounts table. The way I thought of doing this is to grab all the foreign constraints and turn them into cascade delete constraints, then delete as many accounts as I want. After this I will restore the constraints back to their original state.

I've got a problem which I think may be a bug in Postgres, but I wonder if I'm missing something. Two tables, A & B have foreign key relations to each other. A 3rd table C, inherits from A. A stored procedure updates a row in C, adds a row each in B & C. I get an integrity violation. All the foreign keys are deferrable, and the stored procedure is called from within a transaction with constraints deferred. (And the foreign keys do refer to...

Hi all, I read on the manual page for Inheritance that: "A limitation of the inheritance feature is that indexes (including unique constraints) and foreign key constraints only apply to single tables, not to their inheritance children. Thus, in the above example, specifying that another table's column REFERENCES cities(name) would allow the other table to contain city names but not capital names. This deficiency will probably be fixed...

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
