function _update_7000_field_read_fields

Fetches all of the field definitions from the database.

Warning: Unlike the field_read_fields() API function, this function returns all fields by default, including deleted and inactive fields, unless specified otherwise in the $conditions parameter.

Parameters

$conditions: An array of conditions to limit the select query to.

$key: The name of the field property the return array is indexed by. Using anything else than 'id' might cause incomplete results if the $conditions do not filter out deleted fields.

Return value

An array of fields matching $conditions, keyed by the property specified by the $key parameter.
