如何改變一個表在列上添加一個默認值

Question

我使用ms sql 2008我有問題要添加默認值到特定表上的列。

ALTER TABLE dbo.CmsAuthors 
ALTER COLUMN IsContentAuthorPublished 
    ADD CONSTRAINT DF_CmsAuthors_IsContentAuthorPublished DEFAULT 0 

你能告訴我我在做什麼錯嗎？

感謝

試試這個：

ALTER TABLE dbo.CmsAuthors 
    ALTER COLUMN IsContentAuthorPublished 
    ADD CONSTRAINT DF_CmsAuthors_IsContentAuthorPublished DEFAULT 0 
for <Column Name>
