Subject:Re: returning table name
View as plain text  

It looks like the below would be easy with the data reorganized as Tim
suggested. I was wondering about a simlair question in reverse though. I
have three tables that share a item ID as their primary keys , When I delete
an item from the database I need to remove the records from each of these
three tables by itemID. Something like
DELETE  books.*, fbooks.*, sbooks.*
FROM books,fbooks, sbooks 
WHERE books.index=fbooks.index
books.index =3;

But of course this doesn't work.

Can it work? Can you use something like an INNER JOIN with the DELETE?
