ALTER TABLE ... IDENTITY question....

Hi,
I am trying to programatically change the seed of an existing IDENTITY
column (Copy_ID). When I run the following command I get the error:
Server: Msg 156, Level 15, State 1, Line 1
Incorrect syntax near the keyword 'IDENTITY'.
ALTER TABLE Copy ALTER COLUMN Copy_ID Int IDENTITY (1,1);
Where am I going wrong?
Thanks in advance,
StuCheck out DBCC CHECKIDENT in the BOL.

ALTER TABLE

I sometimes use the ALTER TABLe to add certain fields in my table. I need to
do it programatically. I will not get into why eventhough I have access to
Enterprise manager and can use that to do it that way.
My question is I'd like to know if there is syntax that I can use when I
ALTER TABLE and ADD COLUMN to a table. I'd Like to specify where in the tabl
e
to place this new column. For example placing the new field in 3rd position
or place in a table of 20 fields. I'd like to specify where in the table to
place this new field...
thanks in advance...AFAIK you can not
If you look in EM when you do it (save change script icon) you will see that
EM creates a new table drops the old one and renames the newly created one t
o
the original one

Sorry, you cannot do this with ALTER TABLE.
You can, of course, try to do what Enterprise Manager does:

Yep, it does. See http://www.aspfaq.com/2528|||Well if you look at the change script you will see that the isolation level
is SERIALIZABLE
This is the highest level, no updates,inserts or deletes can happen on this
table while this script runs

Hi Mike,
AFAIK, that's only necessary for views defined as SELECT * FROM ...
And since you shouldn't use SELECT * in production code anyway, there's
no need to worry.
