SQL Entry Update

Hi all, I'm new to the forums.
I'm trying to update an entry in my database via command through a shell prompt but it doesn't seem to be working.

I want to update a column called name with a new name which is in a table called users in database db_db1

How would I go about doing this with the UPDATE, SET, WHERE command in one line?

Anyone know??

You would use something like:
ALTER TABLE users CHANGE name new_name VARCHAR 128;


But you should note that the 'new' column may not have all the attributes that the old column does (NOT NULL, etc) unless you explicitly define them too. Indexes may also need to be modified if they're set for this column/table.

You can find more info athttp://dev.mysql.com/doc/refman/5.1/en/alter-table.html
