Script

Hi Folks,
I need a script that it'll changed varchar field to nvarchar a table which i
pass it's name via parameter.
I generated it but it'll raise exception when a field has foreign key etc...
I don't want to spend more time to this work. Do you have a script like
this? Or program?
If you have it could you share with me?
Thanks.Hi
If you try and change a column's data type and the column is referenced by a
foreign key, or is part of a primary key will give you an error. You will
need to drop these before trying to change the columns datatype. The easies
t
way would be to script them, drop them and re-create them afterwards. To dro
p
them see http://www.mssqlserver.com/scripts/drop_keys.sql

But you could script them first, which is what I indicated in the response.
There are several ways to do this, as this is a one off job use Enterprise
Manager. If you take a backup before making any changes and restore the
database under a different name, you could use a tool such as Red Gate's SQL
Compare to check the differences (in fact you could use this to re-apply the
missing FKs and PKs).
