Question

I haven´t much experiences with SQL Server 2008, I´d like to rename all columns in my database (add to existing name some prefix).

I’m thinking something like:

Foreach( column in table)
(
    column_name = prefix+column_name
)

Is there any way to do it??

Thanks so much.

You can try the following solution: iterate through records from sys.columns table using cursor and for each record excute the sp_rename system stored procedure.
I think there can be problems with integrity while renaming, so you need to be careful with other objects (for example stored procedures) that refers for these columns.

UPDATE: MVP says:

if you have any indexes, primary keys, unique keys, or foreign keys, they need to be dropped, and then readded, after the columns have been renamed. If you don’t do this in the correct order, you will get lots of nasty error message.
