Can you give any example of where converting a literal value to appropriate non-unicode literal could ever cause SQL a performance issue?
Or for dates. Our rule is you convert...

Completely disagree with the first sentence. And even more...

Yeah, definitely not 'sa' or some other existing/standard user.

Never use ISNULL in a WHERE or JOIN clause.
Whether the column is nullable or not is irrelevant.

Excuse me? Are you saying that if a database is mirrored and disk-level corruption occurs the SQL will just pull the data from the mirror??
And I believe it...

The simplest rules is:
Never use ISNULL in a WHERE or JOIN clause.
Whether the column is nullable or not is irrelevant.
The proper way to code this:
where isnull(SalesOrderID,-1) = 43665 --NEVER!!
