Are there any DONT DO for SQL and dates when it comes to performance
Specifically i'm trying to optimise this
If i pass in a @TwoDaysBeforeDate as '2014-3-19'
is this the best way, or should i use something like getDate(-2) for performance ?
select * from vwQuickAlertMaster where vDeviceName != '' and dDeviceLoggedDate >= @TwoDaysBeforeDate and bIsacknowledged = 0 and iSoftwarePriority = 3 and bIsAlert = 1 order by dDeviceLoggedDate desc
