Add default value for time(7) field

How can I add a default value for time(7) field in SQL Server ?

I tried to set "00:00:00"开发者_JS百科 to "default value or binding" in SQL Server Management Studio but it didn't work.

Use this T-SQL statement in SSMS:

ALTER TABLE dbo.YourTable
ADD CONSTRAINT DF_TimeDefault DEFAULT '00:00:00' FOR YourTimeColumn

If you want to use the visual table designer, use this notation:

Put your time into single quotes, and put brackets around the value.
