Naming of ID columns in database tables

Question

I was wondering peoples opinions on the naming of ID columns in database tables.

If I have a table called Invoices with a primary key of an identity column I would c

Answer 1

I do hate the plain id name. I strongly prefer to always use the invoice_id or a variant thereof. I always know which table is the authoritative table for the id when I need to, but this confuses me

SELECT * from Invoice inv, InvoiceLine inv_l where 
inv_l.InvoiceID = inv.ID 
SELECT * from Invoice inv, InvoiceLine inv_l where 
inv_l.ID = inv.InvoiceLineID 
SELECT * from Invoice inv, InvoiceLine inv_l where 
inv_l.ID = inv.InvoiceID 
SELECT * from Invoice inv, InvoiceLine inv_l where 
inv_l.InvoiceLineID = inv.ID 

What's worst of all is the mix you mention, totally confusing. I've had to work with a database where almost always it was foo_id except in one of the most used ids. That was total hell.
