Description
Return a new unique ID in the given sequence.
For compatibility reasons, Drupal does not use auto-numbered fields in its database tables. Instead, this function is used to return a new unique ID of the type requested. If necessary, a new sequence with the given name will be created.
Note that the table name should be in curly brackets to preserve compatibility with table prefixes. For example, db_next_id('{node}_nid');
