So I needed to recreate a truncated users table to stop the Drupal admin from barfing all over the admin… the url_alias table has the UID and the user names in it… so why not?

INSERT INTO users SELECT REPLACE(source, ‘user/’, ”) AS uid, REPLACE(alias, ‘users/’, ”) AS name, SHA1(‘nothing’) AS pass, CONCAT(REPLACE(alias, ‘users/’, ”), ‘@no.none’) AS mail, ” AS theme, ” AS signature, ‘filtered_html’ AS signature_format, — make sure this is okay 0 AS created, 0 AS access, 0 AS login, 1 AS status, NULL AS timezone, ‘en’ AS language, 0 AS picture, CONCAT(REPLACE(alias, ‘users/’, ”), ‘@no.none’) AS initial_size, NULL AS data FROM url_alias WHERE source LIKE “user/%” — Only grab users AND source != “user/1” — But not user 1

I didn’t need the emails to be anything useful.
