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

My vote is for InvoiceID for the table ID. I also use the same naming convention when it's used as a foreign key and use intelligent alias names in the queries.

 Select Invoice.InvoiceID, Lines.InvoiceLine, Customer.OrgName
 From Invoices Invoice
 Join InvoiceLines Lines on Lines.InvoiceID = Invoice.InvoiceID
 Join Customers Customer on Customer.CustomerID = Invoice.CustomerID

Sure, it's longer than some other examples. But smile. This is for posterity and someday, some poor junior coder is going to have to alter your masterpiece. In this example there is no ambiguity and as additional tables get added to the query, you'll be grateful for the verbosity.
