sql - Default getdate for Insert date

Question

I have a table called sample and it has a column called [__INSERT_DATE] which is null. Now I want to alter the column with default as getdate(). When I tried the following it gave me an error.

ALTER TABLE sample
ALTER COLUMN [__INSERT_DATE] [datetime] DEFAULT (getdate()) NULL)

Can anyone tell me what the problem is?

Answer 1

Try this:

ALTER TABLE MyTable ADD CONSTRAINT
DF_MyTable_Inserted DEFAULT GETDATE() FOR INSERT_DATE
GO

This assumes your table is named MyTable, the column is INSERT_DATE, and the name of the contstraint is to be DF_MyTable_Inserted
