Fatal Error: PDOException: SQLSTATE[42000] [1049] Unknown database
This isn't a problem with tables, it's a problem with the name of the database.

Drupal is successfully connecting to your database server, but it isn't finding a database with the name mydevelopmentDB (which must be the name of the database specified in settings.php).

To isolate the problem:


Open up PHPMyAdmin for the server in question and run this query:

SELECT * FROM mydevelopmentDB.users


If you get a similar error then you know that you've definitely got the wrong database name.
Make sure that the name of the database on the server matches the case of the database name in settings.php. Depending on your MySQL settings the server may or may not be enforcing case sensitivity on database/table names.
