Question of the Day

Adding Bits I

I have a table, dbo.bittest, where I am testing an application response. This has this structure:

CREATE TABLE [dbo].[BitTest]
(
[insertdate] [datetime] NULL CONSTRAINT [DF__BitTest__insertd__300F11AC] DEFAULT (getdate()),
[a] [bit] NULL
) ON [PRIMARY]
GO
My application runs this code:
INSERT dbo.BitTest
(
    insertdate,
    a
)
VALUES
(DEFAULT, 'true')
GO
