date and GETDATE() issue?

Hi All,

this is just to know if the following behavior is expected or a bug of SQL Server 2008 R2.

I have a table test with a columntest_date of type DATE. This table has records with different values oftest_date. When I run the query:

SELECT * FROM [test] WHERE test_date=GETDATE()

I receive 0 results, whereas if I use this one:

SELECT * FROM [test] WHERE test_date=COVERT(DATE,GETDATE())

I see the correct results.

It seems that GETDATE() is not implicitly converted toDATE when necessary. Is this a bug or an expected behavior?

Here the test table and some records:

CREATE TABLE [dbo].[test](
	[test_id] [int] IDENTITY(1,1) NOT NULL,
	[test_date] [date] NOT NULL,
 CONSTRAINT [PK_test] PRIMARY KEY CLUSTERED 
(
	[test_id] ASC
)WITH (PAD_INDEX  = OFF, STATISTICS_NORECOMPUTE  = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS  = ON, ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY]
) ON [PRIMARY]
GO

INSERT [test] (test_date) VALUES (GETDATE());
INSERT [test] (test_date) VALUES (GETDATE());
INSERT [test] (test_date) VALUES (GETDATE());
INSERT [test] (test_date) VALUES (DATEADD(DAY,-1,GETDATE()));
INSERT [test] (test_date) VALUES (DATEADD(DAY,-1,GETDATE()));
INSERT [test] (test_date) VALUES (DATEADD(DAY,-1,GETDATE()));
INSERT [test] (test_date) VALUES (DATEADD(DAY,-2,GETDATE()));
INSERT [test] (test_date) VALUES (DATEADD(DAY,-2,GETDATE()));
INSERT [test] (test_date) VALUES (DATEADD(DAY,-2,GETDATE()));
