how to query where date with time = date without time in ms sql

Question

I want to do a query with dates this is my sample tsql:

select * from Bookings where StartTime = \'2/15/2014\'

the starttime has value \'2/15/2

Answer 1

The best way to do this is with a simple comparison:

select *
from Bookings
where StartTime >= cast('2014-02-15' as date) and StartTime < cast('2014-02-14' as date);

This is the safest method of comparison, because it will take advantage of an index on StartTime. This property is called "sargability".

In SQL Server, casting to a date should also be sargable, so you could also do:

select *
from Bookings
where cast(StartTime as date) = cast('2014-02-15' as date) ;
