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?
/*

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?

Excuse my typos and sometimes awful grammar. My fingers work faster than my brain does :-P

Please always remember to encapsulate your code in IFCode Markup. For example [code=sql] [/code].

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)
