  hi,

  I am having a table. which is taking by default NULL values...

  Now i want to update the Column default to'XXXX'

  Script:-

  CREATE TABLE [dbo].[Testowners](

  [owner_id] [int] NULL,

  [owname] [varchar](15) NULL

  )

  Alter Script 1:-

  ALTER TABLE Owners

  ALTER Column [owner_id] INT NOT NULL

  Alter Script 2:-

  ALTER TABLE Owners

  ALTER Column owname VARCHAR(35) Default 'XX'

  The first Alter Statement is working fine.

  Cant i use the Default in Alter statement ....

  Thnaks in advance.......

  That is the Books Online entry for SQL Server Compact 3.5 Service Pack 1.

  You want the SQL Server 2008 entry:
