show tables;

Note the table whose name ends with options. I’m on a DreamHost one-click install of Wordpress, so I don’t know what it’s called in a standard installation. Let’s just say it’s called options.

update options set option_value = 'http://www.echographia.com/blog' where option_name = 'siteurl';

If you’re getting this error:

ERROR:  http://gems.datamapper.org does not appear to be a repository
ERROR:  While executing gem … (Gem::RemoteFetcher::FetchError)
bad response Not Found 404 (http://gems.datamapper.org/yaml)

then do this:

gem sources --remove http://gems.datamapper.org
