function field_permission_example_field_schema in Examples for Developers 7

Implements hook_field_schema().

Defines the database schema of the field, using the format used by the Schema API.

We only want a simple text field, similar to the body of a node.

Note that this field has only a normal text (which translates to 16k of text in MySQL), and so therefore doesn't have an index. More complex schema would probably have at least one indexed column.
