Hello,
I have a table which has a foreign key relationship with itself. I
want and expect my updates to cascade (deletes definitely cascade as
expected) but instead I just get error 1217: foriegn key error.
I have written example code to use in reproducing the problem:
# Create the table

How can you indicate that a FOREIGN KEY constraint references two
columns in two different tables?
"SQL Server Books Online" show an example of how to reference two
columns in the SAME table:
REFERENCES ref_table )
Here is the error and the 'bad' SQL code:
Server: Msg 8148, Level 16, State 1, Line 4

When I delete a user (either through the API or through the site manager)
I get:
DELETE statement conflicted with COLUMN REFERENCE constraint 'FK__aspnet_Me__UserI__0F2D40CE'.
The conflict occurred in database 'DB_68465', table 'aspnet_Membership',
column 'UserId'.
Anyone have any idea?

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,...
