[support] D7 What is the result of hook_field_schema?

When I install a module with the following .install file: function my_widget_field_schema($field) { $columns = array( 'duration' => array('type' => 'varchar', 'length' => 8, 'not null' => FALSE), ); return array( 'columns' => $columns, ); } What should the impact be on the database tables? I receive no errors, and watchdog says that the module is installed, and that it is enabled, but I see no tables added to the db that reflect the field name, widget name, etc. -- --- drupal.org/user/367108 linkedin.com/in/jeffrgreenberg accidentalcoder.com / ayendesigns.com @accidentalcoder
