Thanks friends for all your support
i can achieve this task by the following Query,please let me know your feedback
IF EXISTS ( SELECT * FROM INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_NAME = 'Note'
AND COLUMN_NAME = 'LastModifyBy'
AND DATA_TYPE = 'datetime' )
BEGIN
ALTER TABLE [dbo].[Note] ALTER COLUMN LastModifyBy VARCHAR
UPDATE [dbo].[Note]
SET LastModifyBy='0'
ALTER TABLE [dbo].[Note] ALTER COLUMN LastModifyBy BIGINT
END

Id addition to answering Jeff's question:

What version of SQL Server are you using? - This is a SQL Server 7,2000 forum section.

Have you tested the code?

The OP has ignored repeated requests as to the WHY of it.

On top of that he has been warned repeatedly that is a bad idea.

If all he wants is a code drone to issue an SQL statement and closes the door to man-centuries of expertise in doing it the right way, I suggest we let this thread die right now.

Let us not waste a second more of our time with this.

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.
