Hello everybody,
I have an intranet application which is mostly a bunch of data editing
forms.
The database has about 20 tables all related together.
Recently somebody deleted a "the wrong record" and the cascade delete
in sql server did its work nicely :(
When they asked me to put the data back, I looked pretty stupid
as I had no idea how.
How is this normally done in ASP.NET app?

I supposed this is not quite an ASP.NET related question, it's more database
related.
So you should tell us what database you're using.And if you're using MSSQL,
you'll get better chance being answered if you're posting in
microsoft.publi c.sqlserver.ser ver newsgroup.

If it's deleted from the database, then it is gone (no "recycle bin")!
Time to check if the backup procedure really works, I'm afraid.

What database is it ? Sql server, Access, ...
Let me know if you have any more questions...

I remember that if it's MS Access or so, when the record is deleted but not
packed, there's some change to recover...

What I would do is set up an identical set of tables, prefaced
"bk_thetablenam e" and store any records deleted in *that* set of tables.
Kind of like an audit trail.
That way, although you delete records,
you still keep all records, deleted or not, permanently.

In sql server you can undelete it by examening the transaction log. There
are tools to make it easy.
A general approuch it to take backups so you can go back in time or do the
undelete manualy with some copy & pasting.

Or you could do a soft delete. When the user deletes a row you flip a switch
in a column, so :
delete from table where id = 8
becomes
update table set deleted = true
You can make it transparent for the developer by making a view of the table
like this :
Employees_All : a table that has also the deleted records
Employees : SELECT * FROM Employees where deleted = false
Let me know if you have any more questions...

Morgan,
This isn't so much of an ASP.NET question as it is an application design
question.
If an application I build allows the user to delete anything it is at most
only a logical delete. Basically I have a field in each table named
isDeleted. If set to true then that row is 'logically' deleted when it comes
to the application but the data is still there.
In one case I even created a Deleted Items page so the admins could go see
what's been deleted and 'un-delete' anything they wanted to.

That is a viable database design idea, too.
