I have a table with a column defined thus: LOCNumber Varchar(100) in a
table called Bookdata.
If I execute ALTER TABLE BookData ALTER COLUMN LOCNumber varchar(100)
on the table, does any work get done on the table and column?
Or does SqlServer know that the column is already varchar(100) and
nothing
needs to be done?
If it does do some work, how do you tell it not to run this as it is
already a varchar(100) column. Right now my program just blindly does
this ALTER TABLE
statement regardless of any conditions. Is this a potential problem?
Thanks for any help.
