What Features, Commands, Datatypes, Etc. Should Be Generally Avoided?

If you say BETWEEN December 1st and December 31st, SQL Server sees that last parameter as the very beginning of December 31st. Any data from, say, 1AM on December 31st and afterwards is going to be excluded.

Simplicity is a big theme here. Manhandling the engine around with hints usually results in worse performance overall.

Always good advice but its advice for managers rather than developers, right?

Sometimes, a scan is easier especially for grouping.
