I know Scope_Identity(), Identity(), @@Identity, and Ident_Current all get the value of the identity column, but i would love to know the difference.

Don't use this to get() function returns the last identity created in the same session and the same scope.

In SQL Server 2000 or above is there anyway to handle an auto generated primary key (identity) column when using a statement like the following?
Insert Into TableName Values(?, ?, ?)
My goal is to NOT use the column names at all.

Hi, I've got a strange situation with some tables in my database starting its IDs from 0, even though TABLE CREATE has IDENTITY(1,1). This is so for some tables, but not for others. It has worked until today.
