I need a query to hide the time from a datetime field if the time is midnight.
I tried a case statement but that didn't work any ideas?
Thanks

What format do you want? Why are you doing this in SQL Server instead of doing it in the front end?

where are you displaying this, in SSMS or in some SSRS report?
you can convert the values to varchar with a case statement, but is that what you want?
/* object_id create_date StringDate 14675150 2017-06-08 11:46:34.517 2017-06-08 11:46:34 16771167 2017-08-10 14:12:29.613 2017-08-10 14:12:29 33435193 2016-12-13 15:05:33.830 2016-12-13 15:05:33 38291196 2016-10-14 00:00:00.000 2016-10-14 56387270 2016-11-15 14:31:42.447 2016-11-15 14:31:42 71671303 2016-08-03 00:00:00.000 2016-08-03 */ DECLARE @SampleData TABLE([object_id] int,[create_date] datetime)

SELECT *, CASE WHEN [create_date] = CONVERT(date,[create_date]) THEN CONVERT(varchar(10),[create_date],120) ELSE CONVERT(varchar(30),[create_date],120) END AS StringDate

FROM @SampleData

Using Lowell's sample data, here are 2 other options.
SELECT [create_date], LEFT( CONVERT( varchar(24), [create_date], 121), CASE WHEN [create_date] = DATEADD(dd, DATEDIFF(dd, 0, [create_date]), 0) THEN 10 ELSE 23 END), REPLACE( CONVERT( varchar(24), [create_date], 121), '00:00:00.000', '') FROM @SampleData;

Is your requirement really only for exactly midnight? The options above work for exactly midnight as in 2016-12-13 00:00:00.000, what about 2016-12-13 00:00:00.003?

Thanks everyone I ended up using Luis Example
SELECT [create_date], LEFT( CONVERT( varchar(24), [create_date], 121), CASE WHEN [create_date] = DATEADD(dd, DATEDIFF(dd, 0, [create_date]), 0) THEN 10 ELSE 23 END)
