Not that it means much until you upgrade, but you may want to consider avoiding these 2 because they seem to fail in SQL 2012 using Cadavre's test harness:
SELECT DATEADD(dd, DATEDIFF(dd, 0, GETDATE()), 0) + CAST('04:00:00' AS TIME)
SELECT CAST(CAST(GETDATE() AS DATE) AS DATETIME)+CAST('04:00:00' AS TIME)
The message I'm getting is:
Msg 402, Level 16, State 1, Line 40
The data types datetime and time are incompatible in the add operator.
Msg 402, Level 16, State 1, Line 53
The data types datetime and time are incompatible in the add operator.
Another option:
SELECT DATEADD(hour, 4, DATEDIFF(day, 0, GETDATE()))
My thought question: Have you ever been told that your query runs too fast?
My advice:
INDEXing a poor-performing query is like putting sugar on cat food. Yeah, it probably tastes better but are you sure you want to eat it?
The path of least resistance can be a slippery slope. Take care that fixing your fixes of fixes doesn't snowball and end up costing you more than fixing the root cause would have in the first place.
